Question

我们仅在一种设备类型上使用我们的应用程序，我们经常会在其上遇到此错误。

PackageManager的唯一实例是BootupReceiver：

public class RestartHelper extends BroadcastReceiver
{
     @Override
     public void onReceive(Context context, Intent intent) {
          Logger.getInstance().Log("Restart received");

          Intent i = context.getPackageManager().getLaunchIntentForPackage( context.getPackageName() );
          i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
          context.startActivity(i);
     }
}

例外：

此错误与硬件/系统有关吗？

Answer 1

android.os.DeadObjectException意味着你链接到不再存在的东西。

我案例的解决方案是一个与硬件相关的问题，它在设备的后台创建了所有类型的系统进程崩溃。

Answer 2

显然还有另一个PackageManger调用，但不仅仅是在RestartHelper.java中：

at com.cotris.roosapp.StandardActivity.onCreate(StandardActivity.java:49)

你需要检查一下代码细节。

包管理器死了，DeadObjectException
