Android IntentReceiver泄露

Question

在我的Android应用程序中，我有一个Activity MainActivity，它有一个Fragment MainFragment，它启动一个IntentService，然后转换到Activity SelectPlayersActivity（它有一个Fragment SelectPlayersFragment）。当任一活动位于前台时，IntentService可能会完成。所以我必须在他们的片段中注册BroadcastReceivers。我这样做是通过创建在名为“NewGameServiceReceiver”的两个片段中扩展BroadcastReceiver的子类。在这两个片段中，我按如下方式注册BroadcastReiceiver：

private void registerBroadcastReceivers() {
    IntentFilter newGameFilter = new IntentFilter(BroadcastReceivers.NEW_GAME_BROADCAST_RECEIVER.getName());
    newGameServiceReceiver = new NewGameServiceReceiver();
    getActivity().registerReceiver(newGameServiceReceiver, newGameFilter);

}

这是在两个片段中的onStart（）方法中触发的：

@Override
public void onStart() {
    super.onStart();
    registerBroadcastReceivers();
}

我取消注册的两个片段如下：

@Override
public void onPause() {
    super.onPause();
    getActivity().unregisterReceiver(newGameServiceReceiver);
}

但是，当我逐渐转换到第三个Activity时，DDMS报告NewGameServiceReceiver上的内存泄漏。 unregisterReceiver（）方法应该被调用。

07-31 00:01:30.017: E/ActivityThread(2002): Activity
ws.hamacher.cluebuddy.SelectPlayersActivity has leaked IntentReceiver
ws.hamacher.cluebuddy.SelectPlayersFragment$NewGameServiceReceiver@b3822ea0
that was originally registered here. Are you missing a call to
unregisterReceiver()? 07-31 00:01:30.017: E/ActivityThread(2002):
android.app.IntentReceiverLeaked: Activity
ws.hamacher.cluebuddy.SelectPlayersActivity has leaked IntentReceiver
ws.hamacher.cluebuddy.SelectPlayersFragment$NewGameServiceReceiver@b3822ea0
that was originally registered here. Are you missing a call to
unregisterReceiver()?

这是宣告和处理BroadcastReceviers的正确方法吗？请注意，我已在两个片段中为IntentFilters提供了相同的构造函数参数(BroadcastReceivers.NEW_GAME_BROADCAST_RECEIVER.getName())。这是必要的，因为我不知道哪个片段会收到服务的意图。

感谢任何评论/帮助。

Answer 1

首先尝试取消注册接收器，然后调用super.onPause()

@Override
public void onPause() {
    getActivity().unregisterReceiver(newGameServiceReceiver);
    super.onPause();

}

希望这有帮助。
