Saúl Ibarra Corretgé 1460e15a45 Fix NPE when converting camera2 supported sizes
StreamConfigurationMap.getOutputSizes() may return null:
https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap#getOutputSizes(java.lang.Class%3CT%3E)

Fixes:

Fatal Exception: java.lang.NullPointerException: Attempt to get length of null array

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/.
