android - 包管理器已死，DeadObjectException

Question

我们只在一种设备类型上使用我们的应用程序，并且经常在该设备上遇到此错误。

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);
     }
}

异常(exception):

此错误是否与硬件/系统相关？

Answer 1

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

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

你需要检查里面的代码细节。
