Calling join on adapter/engine before calling createClient/createInstance leads to NullPointerException

[divick]

I am trying to integrate agora-react-native-rtm in my project which is pure ES6 and no typescript code base. I want to use agora livestream along with agora-rtm for messaging.

Based on the example in agora-react-native-rtm/example, I have created rtm-adapter which instantiates rtmEngine. But the moment I call rmtEngine.joinChannel(cid); it causes NPE.

The NPE is happening because the rtmClient instance in AgoraRTMModule.java is not created untill AgoraRTMModule::createInstance is called. From what I could gather, this is to be called from React side. But looking at the example in agora-react-native-rtm, I don't see any call to AgoraRTMModule::createInstance or AgoraRTMModule::createClient.

I tried to call createClient on rtmEngine instance, but it failed because it was unable to find the shared libs on the emulator. I copied the shared libs into android/app/src/main/jniLibs and the agora-rtm-sdj.jar into android/app/libs/ folder but now it complains of missing JNI method. Here is the stacktrace for the same.

I understand that right now it is in alpha/beta stage but is there a way I can make it work for the time being at least on android?

I would appreciate any help.
