Question

我无法在Google Play控制台中找到实际处理我的应用程序代码的堆栈跟踪部分。我得到的只是系统内容，没有显示我的代码中导致错误的位置。

java.lang.RuntimeException:

Answer 1

Android是完全开源的。如果您查看ActivityThread handleReceiver()，则可以看到当您的应用收到广播时，系统会调用<receiver android:name=".MyBroadcastReceiver" android:exported="true">。

如果您阅读the source code，您可以看到广播从Android操作系统进入，并转到清单中声明的类。在该页面上给出的示例中，您的清单看起来如下：

public class MyBroadcastReceiver extends BroadcastReceiver {

然后你需要一个像

我会从堆栈跟踪中猜出你在清单中声明了你的APK没有的广播接收器。要么你忘记编写代码，得到类名错误，要么像proguard错误地剥离它（不太可能）。
