webview在设置放大缩小功能时,android.widget.ZoomButtonsController错误解决办法

错误:

Activity com.example.alex.newtestproject.serverapi.XApiActivity has leaked IntentReceiver android.widget.ZoomButtonsController$1@cab7aff that was originally registered here. Are you missing a call to unregisterReceiver()?

解决办法:

@Override    protected void onDestroy() {        super.onDestroy();        ViewGroup view = (ViewGroup) getWindow().getDecorView();        view.removeAllViews();        wvContent = null;    }
