我有一个带有OpenTok视图的React原生Android应用程序（作为原生模块编写）。我遇到了一个崩溃问题（在尝试示例化OpenTok视图时立即出现），影响了旧版Android（SDK 16-19，Jelly Bean到KitKat），任何OpenTok会话。最近的Android手机都没有问题;OpenTok工作完美。
以下是相关的Android logcat输出：

由于看起来缺少org/webrtc/voiceengine/BuildInfo.class，我手动添加了audio_device_java. jar作为库（根据https：//groups.google.com/forum/#！topic/discuss-webrtc/PkfAVr_TYQs上的建议），以查看它是否修复了这个问题。
然而，当我尝试构建时，OpenTok SDK似乎已经有了它，所以手动添加audio_device_java. jar没有帮助：

: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

不知道为什么旧版Android上的应用程序缺少org/webrtc/voiceengine/BuildInfo.class。旧版Android上可能发生了什么？
编辑：我发现这实际上对棒棒糖有效--修改了这个问题，以反映这个问题影响到SDK 19（KitKat）。
