OpenTok not working on older Android (org/webrtc/voiceengine/BuildInfo.class maybe missing)

I have a React Native Android app with an OpenTok view (written as a native module). I'm experiencing a crash problem (immediately upon attempt to instantiate OpenTok view) affecting older Android versions (SDK 16-19, Jelly Bean through KitKat), with any OpenTok session. More recent Android phones have no issues; OpenTok works perfectly.

Here is the relevant Android logcat output:

Since it looked like org/webrtc/voiceengine/BuildInfo.class was missing, I manually added audio_device_java.jar as a library (as recommended on https://groups.google.com/forum/#!topic/discuss-webrtc/PkfAVr_TYQs ) to see if it fixed the issue.

However, it looked like OpenTok SDK already had it when I tried to build, so manually adding audio_device_java.jar did not help:

:app:transformClassesWithJarMergingForDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/webrtc/voiceengine/BuildInfo.class

Not sure why the app on older Android is missing org/webrtc/voiceengine/BuildInfo.class. What could be happening on older Android?

EDIT: I found that this actually works on Lollipop -- modified this question to reflect that the issue affects up to SDK 19 (KitKat).

Solution

  • Finally resolved it on my own! Posting here so that others may find this useful.

    I had multiDexEnabled set to true, so I needed to explicitly specify certain classes to keep for the older platforms to use OpenTok properly (SDK 19 and earlier).

    This means that I had to include multiDexKeepProguard in my app/build.gradle defaultConfig:

    defaultConfig {
    ...
    multiDexEnabled true
    multiDexKeepProguard file('proguard-rules.pro')
    ...
}

    In my multiDexKeepProguard file (mine happens to be a text file named proguard-rules.pro in the app directory), I had to make sure to include the following lines:

    # Keep the following for OpenTok
-keep class com.opentok.** { *; }
-keep class org.webrtc.** { *; }

    This allowed my OpenTok mobile app to work properly for SDK 16 (Android 4.1 Jelly Bean) through SDK 27 (Android 8.1 Oreo).
