It is okay to use AImageReader_\\* and AImage_\\* methods within the callback. Note that it is possible that calling [AImageReader_acquireNextImage](/ndk/reference/group/media#group___media_1ga3f270ebce75bdecc4744f5a72100e1e6) or [AImageReader_acquireLatestImage](/ndk/reference/group/media#group___media_1ga1b6d5dfa37992c8f3dfb8a1b0d7decbd) returns [AMEDIA_IMGREADER_NO_BUFFER_AVAILABLE](/ndk/reference/group/media#group___media_1gga009a49041fe39f7bdc6d8b5cddbe760ca62da64570ae5163a55c88927f8c1f432) within this callback. For example, when there are multiple images and callbacks queued, if application called [AImageReader_acquireLatestImage](/ndk/reference/group/media#group___media_1ga1b6d5dfa37992c8f3dfb8a1b0d7decbd), some images will be returned to system before their corresponding callback is executed."]]
