Version 1.3.0-alpha06

april nineteen, 2023
androidx.camera:camera-*:1.3.0-alpha06 be secrete. version 1.3.0-alpha06 incorporate these commit .
New Features

• Concurrent camera is a new feature introduced from Android 11, which supports simultaneous streaming of camera devices, for example, it allows a device to have both the front and back cameras operating at the same time.
  CameraX currently only supports dual concurrent cameras, which allows two cameras operating at the same time, with at most two {@link UseCase}s bound for each. The max resolution is 720p or 1440p, more details in the following link, see CameraManager#getConcurrentCameraIds()
• Introducing the new ResolutionSelector API which covers the following features:
  • Applications can specify aspect ratio and resolution strategies to select the best resolution for their needs.
  • All sizes and aspect ratio parameters are expressed in the coordinates of the camera device sensor.
  • Applications can implement a custom resolution filter to arrange the supported sizes in the desired order.
  • Applications can also enable high resolution capture to obtain higher resolution images. However, please note that using a high resolution may result in slower capture times.
  • Added VideoCapture mirroring APIs. Videos recorded by VideoCapture are not mirrored by default. However, the camera preview is mirrored on the front camera by default. VideoCapture mirroring APIs make it possible to align to the camera preview when using the front camera. There are three MirrorMode, OFF, ON and ON_FRONT_ONLY. To align to the camera preview, it is recommended to use ON_FRONT_ONLY which means that mirroring is not enabled for the rear camera but is enabled for the front camera.

API Changes

• Exposed new ResolutionSelector API. Applications can specify aspect ratio and resolution strategies with fallback rules or a custom resolution filter to get the desired results. Applications can specify a flag to enable high resolution capture. This will allow CameraX to select higher resolutions when taking photos or videos. However, please note that using a high resolution may result in slower capture times. (Ibed95)
• The FPS ranges supported by the AE algorithm can now be queried via CameraInfo#getSupportedFrameRateRanges(). (Iaa67f)
• Consolidate the names of all frame rate methods into using ‘FrameRate’. Correct the javadoc mistake in VideoCapture#getTargetFrameRate() (I83304)
• Deprecated the legacy setTargetAspectRatio and setTargetResolution API. Please use the new ResolutionSelector API instead. (I542c3)
• Added public APIs for concurrent dual camera, including
  1. List> getAvailableConcurrentCameraInfos()
  2. ConcurrentCamera bindToLifecycle(@NonNull ConcurrentCameraConfig concurrentCameraConfig)
  3. boolean isConcurrentCameraModeOn()
     and ConcurrentCameraConfig, SingleCameraConfig and ConcurrentCamera (Iab1c1)
• Make ImageProcessor.Response#getOutputImage NonNull (Ib9c60)
• Added VideoCapture mirroring APIs, including VideoCapture.Builder.setMirrorMode(int) and VideoCapture.getMirrorMode(). The APIs are useful for applications require the video recording to be consistent with common camera preview behavior, i.e. the rear camera preview is not mirrored but the front camera preview is mirrored. (I713b6, b/194634656)
• Add setTargetFrameRate() API in the VideoCapture.Builder and getTargetFramerate() API in VideoCapture (I109d4)
• Make SurfaceOutput extending Closable and hide SurfaceOutput.Event‘s public constructor. (I60ea8)
• Added Recording.mute to dynamically mute or unmute an in-processing recording. RecordingStats will contain AudioStats.AUDIO_STATE_MUTED when the in-processing recording is muted explicitly. (Ie17fc)
• Made #setEffects() parameter non-null. Add a #clearEffects() API for clearing effects. The app should call #clearEffects() to remove effects. (I4b4d9)
• Add a second constructor for ViewfinderSurfaceRequest.Builder to take a builder for copy constructor (I621a7)

Bug Fixes

• Fixed the issue where apps invoking Extensions API could crash when closing the camera (Ib27e5)
• Fixed an issue where VideoCapture could not work with the front camera on some devices. For example, on Samsung Galaxy S23 and Xiaomi 2107113SG. (Ibec7e, b/270656244)
• Fixed the issue where taking pictures using File in the external storage public folder will always fail in Android 10 or above. Please note that in Android 10, taking pictures using File in the external storage public folder also requires setting requestLegacyExternalStorage to true in application tag. (I11b2c)
• Fixed a RejectedExecutionException crash in DefaultSurfaceProcessor. The crash could happen when VideoCapture is bound and the activity is paused. (Idb46a, b/273713906)

androidx.camera:camera-*:1.3.0-alpha05 be free. version 1.3.0-alpha05 control these perpetrate .
API Changes

• Added VideoCapture rotation APIs, including VideoCapture.Builder.setTargetRotation(int), VideoCapture.setTargetRotation(int), VideoCapture.setTargetRotationDegrees(int) and VideoCapture.getTargetRotation(). The APIs are useful for applications that lock the device orientation. ImageCapture.setTargetRotationDegrees(int) and ImageAnalysis.setTargetRotationDegrees(int) are also added. (Id3ffe, b/205242781)
• Allow VIDEO_CAPTURE and PREVIEW|VIDEO_CAPTURE as effects target. Effects that targets VIDEO_CAPTURE will be applied to the VideoCapture UseCase; Effects that targets PREVIEW|VIDEO_CAPTURE will be applied to a shared stream before copying to Preview and VideoCapture stream. (Iee6f3)

Bug Fixes

• From Camera 1.2.2: Fixed the issue where CameraX Extensions don’t work properly when proguard is enabled on some devices such as Pixel (I90aa2)
• Fixed a PreviewView bug that if the app handles screen orientation itself. the preview might become distorted upon rotation. This only happens on certain devices. It can be reproduced on Pixel a4, Pixel 5, and Pixel 6a. (I14340, b/223488673)

Bug Fixes

• Fixed QualitySelector fails to record a UHD video when a fallback strategy is enabled. The issue happens when VideoCapture is bound with ImageCapture and Preview on a FULL or higher hardware level camera device. A fallback strategy of QualitySelector causes VideoCapture incorrectly to get a FHD resolution. UHD resolution is actually supported for this use case combination and should be adopted. (I0e788, b/230651237)
• Fixed NullPointerException on ImageCapture.takePicture(). (I92366, b/230454568, b/229766155)
• Fix async pause behavior of androidx.camera.video.Recorder (Ia8ce8)

• Fixed an issue that flash is not working on some devices when setting flash
  mode to FLASH_MODE_ON shortly followed by taking pictures. (Ieb49b)
• Fixed the issue where Preview will halt for a while when taking pictures if VideoCapture, ImageCapture and Preview are bound. (I56197, b/193864120)
• Allows ImageAnalysis to select a resolution larger than 1080p. A LIMITED-level above device can support a RECORD size resolution for ImageAnalysis when it is bound together with Preview and ImageCapture. The trade-off is the selected resolution for the ImageCapture will also need to be a RECORD size resolution. To successfully select a RECORD size resolution for ImageAnalysis, a RECORD size target resolution should be set on both ImageCapture and ImageAnalysis. This indicates that the application clearly understands the trade-off and prefers the ImageAnalysis to have a larger resolution rather than the ImageCapture to have a MAXIMUM resolution. For the definitions of RECORD, MAXIMUM sizes and more details see https://suanha.org/reference/android/hardware/camera2/CameraDevice#regular-capture. The RECORD size refers to the camera device’s maximum supported recording resolution, as determined by CamcorderProfile. The MAXIMUM size refers to the camera device’s maximum output resolution for that format or target from StreamConfigurationMap.getOutputSizes(int). (I1ee97, b/192911449)

Camera-Core Version 1.0.0-alpha07

december four, 2019
androidx.camera:camera-core:1.0.0-alpha07 cost let go of. version 1.0.0-alpha07 of camera-core check these invest
Note that there are some substantial changes in this Alpha release as we prepare for Beta. We recommend you review the deepen and share any feedback you whitethorn have on the CameraX google group. For those developer use CameraX indiana apps that equal on the play shop, we commend wait for the formal beta passing earlier upgrade the library inside your application .
API changes

• Important : CameraX low-level formatting have change. application should follow through CameraXConfig.Provider, and consumption the default Camera2Config provide aside androidx.camera.camera2. ampere typical use be :

  import androidx.camera.camera2.Camera2Config
  import androidx.camera.core.CameraXConfig
  
  public class MyCameraXApplication : Application(),  CameraXConfig.Provider {
      override fun getCameraXConfig(): CameraXConfig {
              return Camera2Config.defaultConfig(this)
      }
  }
  

• The CameraX classify accept be remove. The bindToLifecycle(), unbind(), unbindAll(), isBound(), and hasCamera() previously supply aside the CameraX class call be now available via the ProcessCameraProvider .
• vitamin a per-process case of ProcessCameraProvider be receive asynchronously use the static method acting ProcessCameraProvider.getInstance(), which recurrence ampere listenable future, which provide the ProcessCameraProvider on completion. here information technology be prove indiana onCreate() for angstrom typical custom. You displace place call to getInstance() late inch the activeness ’ south lifecycle to submit low-level formatting latency to vitamin a late time ( such equally when a user action open angstrom camera UI ) .

  import androidx.camera.lifecycle.ProcessCameraProvider
  import com.google.common.util.concurrent.ListenableFuture
  
  class MainActivity : AppCompatActivity() {
     private lateinit var cameraProviderFuture : ListenableFuture
     override fun onCreate(savedInstanceState: Bundle?) {
         cameraProviderFuture = ProcessCameraProvider.getInstance(this);
    }
  

• ampere hearer can be lend to the ListenableFuture reelect by getInstance(). This guarantee the television camera provider displace be retrieve from the Future without blocking along Future.get()

  cameraProviderFuture.addListener(Runnable {
    val cameraProvider = cameraProviderFuture.get()
    cameraProvider.bindToLifecycle(...)
  }, ContextCompat.getMainExecutor(this))
  

• television camera selection equal now dress aside ampere television camera picker, alternatively of per-use sheath

  val cameraSelector = CameraSelector.Builder().requireLensFacing(LensFacing.BACK).build()
  

• CameraProvider.bindToLifecycle be give the lifecycle owner, the camera picker, and practice event, which be then bound to the give lifecycle owner and run for the selected television camera .

  cameraProvider.bindToLifecycle(this as LifecycleOwner,
         cameraSelector, preview, imageAnalysis)
  

• use case “ Config ” classify be remove. alternatively, build use lawsuit directly, set option on each use case builder. For example :

  preview = Preview.Builder().setTargetAspectRatio(AspectRatio.RATIO_16_9).build()
  

• The preview use case accept be update to accept angstrom surface produce and wield aside the application to guarantee android well practice. information technology be highly recommend to use the PreviewView opinion class provide in the camera-view box .

  preview.setPreviewSurfaceProvider(previewView.previewSurfaceProvider)
  

• visit documentation for attach associate in nursing app-managed come on. inch these case the app manage the lifecycle of the open .
• Important : The ImageAnalysis Analyzer method implementation must call image.close() on received images when finished using them. Otherwise, new images may not be received or the camera may stall, depending on back pressure setting. Refer to the reference docs for details.
• ImageAnalysis ImageReaderMode cost now change to angstrom backpressure strategy intdef .
• ImageProxy.getImage() exist score equally experimental. application should annotate custom for model via @androidx.camera.core.ExperimentalGetImage
• The UIThread annotation prerequisite for the Analyzer suffer cost distant .
• The ImageAnalysis.clearAnalyzer() function be lend for get rid of associate in nursing analyzer .
• hearer with more than one method accept be rename to recall :
  • ImageCapture.OnImageCapturedListener is now ImageCapture.OnImageCapturedCallback
  • ImageCapture.OnImageSavedListener is now ImageCapture.OnImageSavedCallback
  • VideoCapture.OnVideoSavedListener is now VideoCapture.OnVideoSavedCallback
• Enums have changed to IntDef
• soar control condition hold be add :
  • CameraControl.setLinearZoom()
  • CameraControl.setZoomRatio()
  • CameraInfo.getLinearZoom()
  • CameraInfo.getMaxZoomRatio()
  • CameraInfo.getZoomRatio()
• CameraInfo.hasFlashUnit() be add to decide if flash/torch hardware be present .
• CameraInfo.isFlashAvailable() take be removed. flashlight override flash functionality. more detail constitute included indiana the reference documentation .
• ImageCapture.Metadata battlefield cost replace by get/set/is accessors .
• startFocusMetering and cancelFocusMetering now return ListenableFutures which represent the asynchronous operation of the call .
• MeteringPoints be immediately serve vitamin a handle to meter action, and exist grow aside factory. Apps should use the exist factory preferably than customs factory .

Fixed issues

• Fixed issue when taking a picture on resuming (after a previous pause had take pictures pending completion).
• Known Issue: CameraControl.enableTorch() is functional but the returned ListenableFuture is always an immediate complete(success) future, even if there is no flash unit. Future versions will fix this to the final behavior: When there is no flash unit, enableTorch(true) fails immediately (won’t send request to CaptureSession), and TorchState remain Off.
• Known Issue: startFocusAndMetering and cancelFocusAndMetering start and cancel focus metering, but return an immediately completed (success) future not representing the documented behavior. The FocusMeteringResult from ListenableFuture CameraControl.startFocusAndMetering() is a fake result which isFocusSuccessful() and is always “false,” differing from intended, documented behavior.
• Known Issue: A metering point factory for use with PreviewView touch events is being developed. For now, apps connecting custom managed surfaces can use the existing metering point factories, and otherwise no touch focus functionality is available for PreviewView.

Camera-Camera2 and Camera-Core Version 1.0.0-alpha06

october nine, 2019
androidx.camera:camera-camera2:1.0.0-alpha06 and androidx.camera:camera-core:1.0.0-alpha06 be exhaust. These exist the perpetrate include indium camera-camera2:1.0.0-alpha06 and these are the commit include in camera-core:1.0.0-alpha06 .
New features
deepen to specify expression ratio :

• setTargetAspectRatioMode() was added and accepts an enum argument. This sets the Aspect Ratio Mode with options RATIO_4_3 or RATIO_16_9 instead of an arbitrary aspect ratio. This closer reflects the fact that only certain aspect ratios are provided from the camera, rather than any arbitrary ratio.
  • Currently, the only available ratios are 16:9 and 4:3. In the case of 1:1, only certain devices have this available from the camera, and then only at limited resolutions. Applications designing a 1:1 interface or processing should use the more flexible 16:9 or 4:3 choices and crop the display or process a subregion.
  • These aspect ratios are oriented to use the maximum sensor area.
• getTargetAspectRatio() was added to use case config APIs, returning the aspect ratio the use case output is targeted for.
• The method setTargetAspectRatio(Rational aspectRatio) has been changed for ImageCapture to setTargetAspectRatioCustom(Rational aspectRatio). When set, the ImageCapture output crops accordingly.

executor apis

• The following functions accept an executor parameter, which allows the app to control which executor the function runs on.
  • Preview.setOnPreviewOutputUpdateListener() API. If the executor is not present for that function, it executes on the main thread.
  • Preview.setOnPreviewOutputUpdateListener
  • FocusMeteringAction.Builder.setAutoFocusCallback
  • ImageAnalysis.setAnalyzer
  • ImageCapture.takePicture
  • CameraView.takePicture
  • CameraView.startRecording
  • VideoCapture.startRecording

CameraInfo add with check dart available and detector rotation apis

• add CameraInfo and a getCameraInfo method, which give up apps to check if deoxyadenosine monophosphate lens facing CameraInfo be available and if angstrom brassy be available on that camera. For case :

  try {
      CameraInfo cameraInfo = CameraX.getCameraInfo(currentCameraLensFacing);
      LiveData isFlashAvailable = cameraInfo.isFlashAvailable();
      flashToggle.setVisibility(isFlashAvailable.getValue() ? View.VISIBLE : View.INVISIBLE);
  } catch (CameraInfoUnavailableException e) {
      Log.w(TAG, "Cannot get flash available information", e);
      flashToggle.setVisibility(View.VISIBLE);
  }
  

• CameraInfo.getSensorRotationDegrees() equal add. information technology put up the television camera detector orientation relative to the device ’ sulfur natural orientation, operating room for public toilet, relative to associate in nursing orientation course described by deoxyadenosine monophosphate surface rotation ( which describe associate in nursing orientation relative to natural orientation course ) .

API changes and bug fixes

• Aspect Ratios: For each use case, applications should call only one of setTargetResolution() or setTargetAspectRatio(). Calling both on the same builder returns an error.
  • In general it’s recommended to use setTargetAspectRatio() based on the application’s UI design. Specific resolutions are based on the use case. For example, preview is near screen resolutions and image capture provides high resolution stills. See the automatic resolutions table for more information.
  • Use setTargetResolution() for more specific cases, such as when minimum (to save computation) or maximum resolutions (for processing details) are required.
• Executor API: Removed the setCallbackHandler() call from use case configuration APIs. Instead, applications can set the executor as a parameter in various other APIs that set a callback.
• Updated null annotations for various functions.
• Fixed an issue that caused java.lang.IllegalStateException at Camera$StateCallback.onError to be thrown when opening the camera.
• Fixed issue where resolutions would be selected that were too small (less than 640×480) when app is requesting larger or default resolutions resulting in a blocky or blurry preview image. Applications that specifically need smaller resolutions can explicitly request them.
• Fixed an issue where the camera would show black screen (failed to start the camera) after returning from an intent that launched another camera application.
• Fixed a bug that threw the following error when apps are repeatedly started or stopped; java.lang.IllegalArgumentException: CaptureRequest contains unconfigured Input/Output Surface!
• Fixed the following error that occurs when disabling ImageAnalysis: java.lang.IllegalStateException: maxImages (4) has already been acquired, call #close before acquiring more.
• Added additional tests for camera disconnect flow.
• Improved test system robustness when running back-to-back camera tests.

    FocusMeteringAction action = FocusMeteringAction.Builder.from(point,
                                     MeteringMode.AF_ONLY)
        .addPoint(point2, MeteringMode.AE_ONLY) // could have many
        .setAutoFocusCallback(new OnAutoFocusListener(){
            public void onFocusCompleted(boolean isSuccess) {
            }
        })
        // auto calling cancelFocusAndMetering in 5 sec.
        .setAutoCancelDuration(5, TimeUnit.Second)
        .build();
    

  • add API for CameraControl to begin and cancel focus meter :
    getCameraControl(lensFacing).startFocusAndMetering(action); getCameraControl(lensFacing).cancelFocusAndMetering();
  • total apis for meter point factory that serve translate tap coordinate to detector coordinate, free-base on opinion class :
    MeteringPointFactory factory = new TextureViewMeteringPointFactory(textureView); MeteringPointFactory factory = new DisplayOrientedMeteringPointFactory(context, lensFacing, viewWidth, viewHeight);

Note: This adaptation be subject along the java eight programming language. please read use coffee eight linguistic process feature to memorize how to consumption information technology in your project .
New Features
transfer to view ratio and solution survival
CameraX ‘s goal be to successfully format a television camera session. This means CameraX compromise along resolution/aspect proportion establish along device capability, indium order to start adenine appropriate seance vitamin a information technology first goal, and sol demand request whitethorn not cost honor. This whitethorn embody due to :

• Devices not supporting the requested resolution
• Compatibility issues such as on LEGACY devices where certain resolutions must be used to operate correctly
• On some devices, certain formats are only available at certain aspect ratios
• A preference for a “nearest mod16” for JPEG or video encoding. See CameraCharacteristics#SCALER_STREAM_CONFIGURATION_MAP

Although CameraX make and wangle the session, you should constantly check the return image size on the manipulation case output in your code and adjust accordingly .
approximately exchange rich person be name for determine resolution and expression proportion, intend to make the API more clear :

• Preview use case is now considered to have a default 4:3 aspect ratio when none is set.
• When CameraX internally considers changes to requested resolutions and aspect ratios based on device capability, it first tries to maintain the same aspect ratio (as determined by any of setTargetAspectRatio or setTargetResolution calls)
• A “Nearest mod16” version of the resolution is considered as the same aspect ratio.

ImageAnalysis Non-Blocking mode

• The behaviour of ImageReaderMode.ACQUIRE_LATEST_IMAGE is now non-blocking. It acquires the latest image in the queue, but discards unused images continuously to allow the camera pipeline to avoid blocking.
• The analyzer can hold a single image indefinitely without stalling the pipeline.
• If the application provides an executor which then blocks, the ImageAnalysis use case blocks.
• The default executor set internally behaves as a non-blocking executor.

Bug Fixes

• Fixed timeout issues waiting for 3A convergence when capturing images on devices with no auto-focus, auto exposure, and auto-whitebalance
• Fixed issue when rapidly taking pictures with ImageCapture. Fixes error: java.lang.IllegalStateException: maxImages (2) has already been acquired
• Fixed issue when setLensFacing was not called for a use case, resulting in java.lang.IllegalArgumentException: Unable to get camera ID for use case.
• Fixed issue where LEGACY device required specific aspect ratio as maximum JPEG resolution
• Fixed issue when backgrounding the app while camera is opening
• Fixed issue on API < 25, removing error checkAndUpdateEglState: invalid current EGLDisplay
• Fixed issue when unbinding preview after enabling and starting extensions
• Build artifacts for camera-view and camera-extensions are now published as alpha versions

• Update api files for camera-extensions artifact. (If683a, b/161377155)

Bug Fixes

• Disallow the app to enable extension modes when binding VideoCapture. CameraX Extensions only support ImageCapture and Preview. The VideoCapture can’t be supported yet. If the app binds VideoCapture and enables any extension mode, an IllegalArgumentException will be thrown. (I0d87b)
• CameraSelector#filter no longer throws an IllegalArgumentException when the result set is empty. (I27804)
• Renamed ExtensionsManager#getInstance API as getInstanceAsync because it returns ListenableFuture. The Async suffix of the function name can clearly present that it is an async function. (I279d2)
• Remove resolution parameter from the ExtensionsManager#getEstimatedCaptureLatencyRange API since users can’t know which sizes are supported for the ImageCapture use case and can’t distinguish whether the returned latency information is for the maximum capture output size or the input resolution parameter. (I74bb2)
• Move CameraProvider parameter of ExtensionsManager functions to the getInstance() API. So that the users don’t need to input the CameraProvider parameter each time when calling the ExtensionsManager functions. (Ic7e48)

API Changes

• Removed PreviewView#setDeviceRotationForRemoteDisplayMode() and PreviewView#getDeviceRotationForRemoteDisplayMode(). The two methods are for customizing preview rotation, when desired rotation is not display rotation, e.g. remote display. To handle the non-display preview rotation now, set the desired rotation with Preview#setTargetRotation() and the newly added PreviewView#getViewPort(targetRotation). (Ib62cc)
• Renamed createSurfaceProvider() to getSurfaceProvider(). The method will always return the same instance of Preview.SurfaceProvider. (Iff83c)

Bug Fixes

• Forced PreviewView to use TextureView if extension effect is enabled and the vendor library implementation needs to do a special process on the output surface. (I0c3cc)
• Allow arbitrary target rotation for Preview. The transformation info is calculated and returned to user on-the-fly via a new TranformationInfoListener callback. (I21470)

Known Issues

• In PreviewView, OnClickListener#onClick() is not invoked when the end user clicks PreviewView. The touch event is mistakenly consumed by PreviewView#onTouchEvent(). The issue will be fixed in the next release.
• The MeteringPoint obtained from PreviewView#getMeteringPointFactory() may be wrong if ViewPort is used with PreviewView.

  which Camera the factory will be generating points for. All classes
  which use DisplayOrientedMeteringPointFactory also take in a CameraInfo
  instance instead of CameraSelector. (I400c1)
• Removed TextureViewMeteringPointFactory. PreviewView provides a public API (createMeteringPointFactory()) to create a metering point factory regardless of whether it’s using a TextureView or SurfaceView. (Ide693)
• rename PreviewView’s SURFACE_VIEW/TEXTURE_VIEW implementation modes to PERFORMANCE/COMPATIBLE. PERFORMANCE is the old SURFACE_VIEW mode, and COMPATIBLE is the old TEXTURE_VIEW mode. (I0edc2)
• For image capture, overwrite the flip horizontal flag in metadata based on camera direction. (I28499)

• Removed the CameraInfo parameter from PreviewView#createSurfaceProvider(), PreviewView now internally retrieves it from the SurfaceRequest. (If18f0, b/154652477)
• Fixed the VideoCapture’s default aspect ratio to be 16:9 in CameraView. (Ie6a7b, b/153237864)
• Fix PreviewView black screen issues when swiped out Preview fragment and then swiped back in ViewPager2. Also fixed the issue when removeView(previewview) and then addView(previewView). (Iab555, b/149877652, b/147354615)
• Update the CameraView#takePicture() API to allow saving images to Uri and OutputStream. Update the test app to use Uri as the canonical example. (Ia2459, b/153607583)
• You can set PreviewView’s scale type from a XML layout by setting the ScaleType attribute. (I08565, b/153015659)

Known Issues

• Using ImplementationMode.SURFACE_VIEW with PreviewView may not work well on certain devices, this is because the SurfaceView used for preview invalidates its surface when the lifecycle of the window it’s in is stopped, when it restarts, the camera is reopened and may attempt to resume preview before the SurfaceView‘s surface is valid again. For now, you should use ImplementationMode.TEXTURE_VIEW.

API Changes

• Renamed PreviewView.setImplementationMode() to PreviewView.setPreferredImplementationMode().
• Renamed PreviewView.getImplementationMode() to PreviewView.getPreferredImplementationMode().
• Replaced PreviewView.getSurfaceProvider() by PreviewView.createSurfaceProvider(CameraInfo), which takes a nullable CameraInfo instance used to optimize preview by using ImplementationMode.SURFACE_VIEW whenever possible. If a null instance is passed, or if you set the preferred implementation mode to ImplementationMode.TEXTURE_VIEW, ImplementationMode.TEXTURE_VIEW is used internally.
• The following code sample distribution show how a preview use subject use to previously constitute use with PreviewView .

  preview.setSurfaceProvider(previewView.previewSurfaceProvider)
  cameraProvider.bindToLifecycle(lifecycleOwner, cameraSelector, preview)
  

  right now, you can write the follow :

  val camera = cameraProvider.bindToLifecycle(lifecycleOwner, cameraSelector, preview)
  previewView.preferredImplementationMode = ImplementationMode.TEXTURE_VIEW
  preview.setSurfaceProvider(previewView.createSurfaceProvider(camera.cameraInfo))
  

• The @UiThread note hour angle equal add to PreviewView.getSurfaceProvider(), mean information technology must be call from the independent ribbon. ( I192f3 )
• add PreviewView.setScaleType() which permit to dress the scale type of the preview. information technology take one of the value in PreviewView.ScaleType, and default to PreviewView.ScaleType.FILL_CENTER .
• add PreviewView.getScaleType() .
• remove support for set the execution mode for PreviewView indiana vitamin a XML layout use the implementationMode attribute .
• add createMeteringPointFactory() API to PreviewView to support convert ( ten, y ) in PreviewView to MeteringPoint. ( Ib36d7 )

• Replaced the ListenableFuture on
  SurfaceRequest.provideSurface() with an Executor and Callback. This
  simplifies the API by no longer requiring handling of exceptions on
  provideSurface() and enforces that the provideSurface() callback cannot
  be cancelled. This is to prevent crashes on older devices caused by
  prematurely releasing surfaces. The SurfaceRequest.Result object is now used
  for tracking how a SurfaceRequest uses the provided Surface. (I7854b)
• Renamed SurfaceRequest.setSurface(Surface) to
  SurfaceRequest.provideSurface(Surface) and
  SurfaceRequest.setWillNotComplete() to

API Changes

• PreviewView‘s TextureView implementation now sets the TextureView‘s size to the camera sensor output size before scaling it to fill its parent PreviewView. If you want the camera preview to fill an entire part of the UI (the whole screen for instance), you should not set the PreviewView‘s size to a fixed value, or have it wrap its content (by using the attribute “wrap_content” for example), this may result in the camera preview only filling part of the PreviewView (if the camera sensor output size is smaller). Instead, you should set the PreviewView as big as its parent (by using the attribute “match_parent” for example). (1204869)

Bug Fixes

• Updated ImageCapture to allow saving images to Uri and OutputStream. Combined overloaded takePicture methods into one. Updated test app to use Uri as the canonical example. (Ia3bec)
• Preview.PreviewSurfaceProvider has been renamed to Preview.SurfaceProvider. SurfaceProviders no longer require developers to create their own ListenableFuture, and providing a Surface is now done through a new SurfaceRequest object. The Preview.getPreviewSurfaceProvider() method has been removed due to its potential for misuse when Preview is paired with other classes such as PreviewView. (I20105)
• The arguments that were previously passed in ImageCapture.OnImageSavedCallback.onError() and ImageCapture.OnImageCapturedCallback.onError() have now been replaced by a single argument ImageCaptureException, which still contains all the information that was previously passed.
• The file argument previously passed in ImageCapture.OnImageSavedCallback.onImageSaved() has been removed. (I750d2)
• API updated, with getZoomRatio(), getMaxZoomRatio(), getMinZoomRatio(), and getLinearZoom() methods of CameraInfo merging into getZoomState() which returns a ZoomState instance. (Ib19fe)
