我正在facebook integrating with existing apps之后的棕色地带工作。到目前为止，所有人似乎都在建所以我用MyReactActivity换了一个当前工作的Activity - 只是为了快速看到我的React App连接到应用程序。我成功构建但是当我单击按钮启动MyReactActivity时，应用程序崩溃了。希望有人有另一个建议。
这是我换出的内容（刚刚更改为MyReactActivity）
context.startActivity(MyReactActivity.intent(context));
看github issues我注意到了一个推荐的修复，但我的代码实际上已经有了，可能是因为我正在使用react v.40：
-keepclassmembers class * { @com.facebook.react.uimanager.annotations.ReactProp <methods>; }
-keepclassmembers class * { @com.facebook.react.uimanager.annotations.ReactPropGroup <methods>; }

答案 0 :(得分：1)
对我而言，解决方案是改变：
compile ("com.facebook.react:react-native:+") {
exclude group:'com.facebook.stetho', module:'stetho'
}
为：
compile ("com.facebook.react:react-native:0.42.3") {
exclude group:'com.facebook.stetho', module:'stetho'
}
这是因为我们内部的maven中心只允许我们将React Native更新为.20，即使使用+。较旧版本的react native与大于23的SDK或Google支持库不兼容，我们使用的是25。
