android - OpenTok 不适用于较旧的 Android(可能缺少 org/webrtc/voiceengine/BuildInfo.class)

Question

我有一个带有 OpenTok View 的 React Native Android 应用程序(编写为 native 模块)。我在任何 OpenTok session 中遇到崩溃问题(在尝试实例化 OpenTok View 时立即发生)影响旧的 Android 版本(SDK 16-19，Jelly Bean 到 KitKat)。最近的 Android 手机没有问题； OpenTok 完美运行。

这是相关的 Android logcat 输出:

由于看起来缺少 org/webrtc/voiceengine/BuildInfo.class，我手动将 audio_device_java.jar 添加为库(按照 https://groups.google.com/forum/#!topic/discuss-webrtc/PkfAVr_TYQs 上的建议)以查看它是否解决了问题。

但是，当我尝试构建时，OpenTok SDK 似乎已经有了它，因此手动添加 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

不确定为什么旧版 Android 上的应用程序缺少 org/webrtc/voiceengine/BuildInfo.class。在较旧的 Android 上会发生什么？

编辑:我发现这实际上适用于 Lollipop——修改了这个问题以反射(reflect)该问题影响到 SDK 19 (KitKat)。

Answer 1

终于自己解决了!在此张贴，以便其他人可能会觉得有用。

我将 multiDexEnabled 设置为 true，因此我需要明确指定某些类以保留旧平台以正确使用 OpenTok(SDK 19 及更早版本)。

这意味着我必须在我的 app/build.gradle defaultConfig 中包含 multiDexKeepProguard:

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

在我的 multiDexKeepProguard 文件中(我的恰好是 app 目录中名为 proguard-rules.pro 的文本文件)，我有确保包括以下几行:

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

这让我的 OpenTok 移动应用程序可以在 SDK 16(Android 4.1 Jelly Bean)到 SDK 27(Android 8.1 Oreo)上正常工作。
