(Android) Native API support of WebRTC

[Kailash Kumar]

Hi,

I am planning to use WebRTC C++ APIs in JNI layer of Android app.

Here is what I have done so far:

1) Compiled WebRTC libraries for android platform and ARM architecture. Verified that compiled libraries are for ARM 32 bit architecture.

2) Copied WebRTC headers into Android Project specific folder.

3) Just added one header file to begin with  -   "webrtc/api/peerconnectioninterface.h" file in one of JNI C++ file.

With both libjingle_peerconnection.so as well as libwebrtc.a, I am getting undefined reference errors for symbols in webrtc code base:

Sample error:

webrtc/api/datachannelinterface.h -

Error:(66) undefined reference to 'rtc::CopyOnWriteBuffer::CopyOnWriteBuffer(rtc::CopyOnWriteBuffer const&)'

Error:(64) undefined reference to 'rtc::CopyOnWriteBuffer::~CopyOnWriteBuffer()'

May more such undefined symbol errors follow.

Is it possible to use WebRTC libraries in completely C++ codebase using above approach on Android platform?

Thanks

Kailash

Any reason you can not use the JAVA API (https://webrtc.org/native-code/android/) for your android application?

Thanks Kaiduan. At present I am looking for feasibility of WebRTC APIs completely in C++ codebase for Android Platform.

If not possible, I will definitely look into Java implementation.

Please let me know if pure C++ support over webrtc is possible for Android Platform.

Thanks

The audio layer needs Java and there are most likely more parts that depend on Java, e.g. video.
