Method Details

__staticInitializer__

@Implementation(minSdk=35)
protected static void __staticInitializer__()

The ImageReader static initializer invokes its own native methods in static initializer. This has to be deferred starting in Android V.

nativeInit

@Implementation(maxSdk=32)
protected void nativeInit(Object weakSelf,
 int w,
 int h,
 int fmt,
 int maxImgs,
 long consumerUsage)

nativeInit

@Implementation(minSdk=33,
                maxSdk=34)
protected void nativeInit(Object weakSelf,
 int w,
 int h,
 int maxImgs,
 long consumerUsage,
 int hardwareBufferFormat,
 int dataSpace)

nativeClose

@Implementation(maxSdk=34)
protected void nativeClose()

nativeReleaseImage

@Implementation(maxSdk=34)
protected void nativeReleaseImage(Image i)

nativeGetSurface

@Implementation(maxSdk=34)
protected Surface nativeGetSurface()

nativeDetachImage

@Implementation(maxSdk=32)
protected int nativeDetachImage(Image i)

nativeDiscardFreeBuffers

@Implementation(maxSdk=34)
protected void nativeDiscardFreeBuffers()

getSurface

@Implementation
protected Surface getSurface()

This is a Java shim to support ImageReader.setOnImageAvailableListener(OnImageAvailableListener, Handler)} until it is supported in native libhostgraphics.

nativeImageSetup

@Implementation(maxSdk=32)
protected int nativeImageSetup(Image i)

Returns:

A return code ACQUIRE_*

nativeImageSetup

@Implementation(minSdk=33,
                maxSdk=33)
protected int nativeImageSetup(Image i,
 boolean legacyValidateImageFormat)

nativeImageSetupPostT

@Implementation(minSdk=34,
                maxSdk=34,
                methodName="nativeImageSetup")
protected int nativeImageSetupPostT(Image i)

nativeClassInit

@Implementation(maxSdk=34)
protected static void nativeClassInit()

We use a class initializer to allow the native code to cache some field offsets.
