// Minimal binary interface definitions for AImage,AImageReader
// and ANativeWindow based on include/media/NdkImage.h,
// include/media/NdkImageReader.h and include/android/native_window_jni.h
// from the Android NDK for platform level 26+. This is only
// intended for use from the AndroidImageReader wrapper for building
// without NDK platform level support, it is not a general-use header
// and is not complete. Only the functions/data types which
// are currently needed by media/gpu/android/image_reader_gl_owner.h are
// included in this ABI
//
// Please refer to the API documentation for details:
