Activity已泄露最初在此处注册的IntentReceiver.你是否错过了对unregisterReceiver()的调用？

Question

01-16 16:52:42.211: E/ActivityThread(2529): Activity com.Civilcourage.CivilcurageSplash has leaked IntentReceiver com.google.android.gcm.GCMBroadcastReceiver@405282e0 that was originally registered here. 

Are you missing a call to unregisterReceiver()?

上述错误的原因是什么？怎么可以避免？

Answer 1

不要依赖onStop(),因为:

请注意,在低内存情况下,系统没有足够的内存来保持活动进程在调用onPause()方法后运行

在onPause()中取消注册您的接收器:

@Override
protected void onPause() {
    super.onPause();

    unregisterReceiver(yourReceiver);
}

Answer 2

您需要在停止活动时取消注册接收器:

@Override
protected void onStop()
{
    unregisterReceiver(yourReceiver);
    super.onStop();
}

Answer 3

您可以unregister尽快收到broadcastreceiver

 @Override
 public void onReceive(Context context, Intent intent) {
     getActivity().unregisterReceiver(this);
 }
