Sami Kalliomäki 9160b627d7 Improve thread safety of AndroidVideoTrackSource::SetState.
1. Prevents deadlocks from AsyncInvoker destructor
2. Makes future state() calls are guaranteed to return the new state after
   SetState() completes.

I am not sure if it is allowed to call FireOnChanged from non-signaling
threads so I will leave the post for now.

This directory holds a Java implementation of the webrtc::PeerConnection API, as
well as the JNI glue C++ code that lets the Java implementation reuse the C++
implementation of the same API.

To build the Java API and related tests, make sure you have a WebRTC checkout
with Android specific parts. This can be used for linux development as well by
configuring gn appropriately, as it is a superset of the webrtc checkout:
fetch --nohooks webrtc_android
gclient sync

You also must generate GN projects with:
--args='target_os="android" target_cpu="arm"'

More information on getting the code, compiling and running the AppRTCMobile
app can be found at:
https://webrtc.org/native-code/android/

To use the Java API, start by looking at the public interface of
org.webrtc.PeerConnection{,Factory} and the org.webrtc.PeerConnectionTest.

To understand the implementation of the API, see the native code in src/jni/pc/.
