Question

在我的应用中，我使用下面的代码向用户显示通知设置。

以下是代码。

    private void startNotificationSettings(){
    final Activity activity =  getActivity();
    Intent intent = new Intent();
    intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS");

    if(UIUtils.isAVersion(8)){
        intent.putExtra("android.provider.extra.APP_PACKAGE", activity.getPackageName());

    }else if(UIUtils.isAfterVersion(Build.VERSION_CODES.LOLLIPOP )){
        intent.putExtra("app_package", activity.getPackageName());
        intent.putExtra("app_uid", activity.getApplicationInfo().uid);
    }else{
        Util.alert(activity,"Warning!","Operation not supported for your OS version",Util.ALERT_NO_ACTION);
        return;
    }
    startActivity(intent);
}

它没有问题但是当我按下后退按钮时它会抛出下面的错误。

Activity com.android.settings.Settings$AppNotificationSettingsActivity has leaked IntentReceiver com.android.settings.accounts.AuthenticatorHelper@cb5c59f that was originally registered here. Are you missing a call to unregisterReceiver()?

知道怎么不泄漏这个？

由于

Answer 1

您没有为unregisterReceiver()

上BroadcastReceiver注册的registerReceiver()致电AppNotificationSettingsActivity的问题

在停止活动时取消注册您的收件人：

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

启动android通知设置活动会导致泄漏意图接收器
