Restrict audioformat to 8bit, 16bit or float PCM with an annotation and a warning. TextToSpeech.synthesizeToFile has only ever worked with 8bit and 16bit PCM. In case of float PCM an invalid file would be generated and in case of other encodings the TTS engine would crash. Also add more annotations to SynthesisCallback.

Add new TTS API. Much of existing API is reused (mostly on the service side). The new API provides better support for network-based synthesis, defines explicit synthesis fallback support, has better error handling, allows for multiple different voices per locale, features enumeration and custom extensions on a voice level and many more. If a service does not provide a V2 implementation, a basic adapter from V2 to existing V1 implementation is provided. Bug: 8259486 Change-Id: I797b7fc054f11c9b0d930f4dea582e57596ea127

Simplify the implementation of AudioPlaybackHandler. Now uses a queue of runnables, one per synthesis. Also introduce an abstraction that wraps AudioTrack that implements the blocking semantics that we desire. bug:5680699 Change-Id: I34a1248ff05766a7d9b3002055fb5b24aa9f230b

Fix regressions in TTS completion callbacks. (a) onUtteranceCompleted should be called on errors too. Also, fix up the error handling so that onUtteranceCompleted is always called. (b) Don't treat empty utterances as errors, and let the engine synthesize them, as before. bug:5662598 Change-Id: I9223592bc6fe5f47d71103f4f02f046b54a655a8

Don't allow TTS engines to synthesize too for ahead. For each synthesis request, we inspect the number of bytes of audio that have not been written to the mixer yet and if that is above a certain threshold (currently 500ms), we block the synthesis thread. bug:5214603 Change-Id: I24c64c48466bdb96ce47b34cee7da2523ee5f0eb

Remove the completeAudioAvailable API. Measurements have shown that the audio track in streaming mode is pretty efficient as is, thanks to dalvik's JNI implementation. Also, in streaming mode write( ) blocks until all data has been copied to the mixer, which is the kind of behaviour we want so that we don't have to explicitly block in our code. Also, the java AudioTrack is thread-safe with respect to stop( ) calls during write, which means we can do everything completeAudioAvailable did, just as efficiently without it.

Implement QUEUE_FLUSH and QUEUE_DESTROY addition modes. Note that this change is slightly more flexible, it defines a priority for each playback request. We needn't really throw away synthesis requests from other apps. We could just play them after higher priority ones (for e.g from talkback). Change-Id: I6c7dd9abe4871e87da08d9aaa4c55225a69078e5
