android - 小部件。 Activity 泄露了 IntentReceiver

Question

在我的 Widget 中，我使用:

Intent intent = new Intent(context, ClassForWidget.class); 
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); 
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget1);            
views.setOnClickPendingIntent(R.id.layout_widget1, pendingIntent);`

我的类 ClassForWidget 已经有一个 BroadcastReceiver:

BroadcastReceiver myReceiver = new MyReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(MyService.MY_ACTION);
registerReceiver(myReceiver, intentFilter);

所以，当我点击 Widget 时，出现错误:

Activity .ClassForWidget has leaked IntentReceiver .ClassForWidget$MyReceiver@40ebe710 that was originally registered here. Are you missing a call to unregisterReceiver()?

我该如何解决？谢谢。

通常你应该在onResume注册，在onPause(或onStart和onStop)取消注册。

protected void onPause() {
     if (myReceiver != null){
         unregisterReceiver(myReceiver);
         myReceiver = null;
     }

}

希望对你有帮助。
