我在运行4.4.2的SAMSUNG-SGH-I337上发生了以下崩溃：

我只在BroadcastReceiver内注册我的MyActivity#onResume，我只在MyActivity#onPause内取消注册。

基本上，似乎onPause在没有相应的onResume的情况下被调用，或Activity#registerReceiver由于某种原因而失败。

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    myFilter = new IntentFilter("myIntent");
    myReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
        }
    };
}

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(myReceiver, myFilter);

}

@Override
protected void onPause() {
    unregisterReceiver(myReceiver);
    super.onPause();
}

这似乎与Receiver not registered类似，但这是由作者没有创建他们的BroadcastReceiver造成的，正如您所看到的，我绝对创造了我的。

Google seems to think this is a Samsung-only problem.因此，我可能只需要通过IllegalArgumentException中的onPause来解决问题。

Android可以在没有Activity＃onResume的情况下调用Activity＃onPause，还是Context＃registerReceiver会失败？
