Java API for android acoustic echo cancellation.

webrtc-based-android-aecm

Java API for android acoustic echo cancellation.

I already tested and using it on a LAN demo several monthes ago, it worked well most of the time but sometimes with little squeal, I know there must have something todo to make it better. To make it better

1. Maybe I should build the whole VOE and using the C++ interface proveded by apm? I'll try this later.
2. The API is a low level one, most of them are just wrappers of native WebRTC aecm interface. We should handle so many things by ourselves, like estimate the echo tail，handle capture/render threads etc. I'm planning to provide a higher level of the API, which can handle those things for us automatically.

TODO List

1. Build the apm interface.
2. Provide a higher level of the API.
3. Provide a VoIP demo to show how to use this API instead of doing AECM on PCM files.
