应用程序关闭或最小化时推送通知没有声音

Question

我正在使用 fcm 在我的 Android 应用程序中获取推送通知。当应用程序打开和关闭或最小化状态时，我也能很好地收到通知。但问题是当应用程序处于最小化或关闭状态时我没有收到通知声音。

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {


@Override
public void onTokenRefresh() {
   String refrehedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d("refreshedtoken",refrehedToken+"");
    PrefUtils.saveToPrefs(getApplicationContext(),PrefUtils.DEVICETOKEN,refrehedToken);
    sendRegistrationToServer(refrehedToken);

}

private void sendRegistrationToServer(String refrehedToken) {

}

}

我没有足够的声誉来添加评论，所以我是为你这样做，但我知道这是不合适的。

原因是当应用最小化时，或者在后台，通知传递到 Android 通知传递到 Android 通知托盘。有两种有效载荷，一种是“数据有效载荷”，另一种是“通知有效载荷”。只需删除“通知负载”即可正常工作。

我已经编辑了我的代码，你忘了添加 .setSound。我还添加了一些您将来可能需要的其他内容。

private void sendNotificatin(String title, String message) {

private void sendNotificatin(String title, String message) {
    Intent intent = new Intent(this,SplashScreen.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent, PendingIntent.FLAG_ONE_SHOT);
     Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.app_ic)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(sound) // changed from SET_DEFAULTS
            .setContentIntent(pendingIntent);
            /* Begin other added stuff */
            .setLights(0xffff0000, 500, 250);
            .setWhen(System.currentTimeMillis())
            /* End other added stuff */
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    Random random = new Random();
    int num = random.nextInt(99999-1000)+1000;
    notificationManager.notify(num,notificationBuilder.build());

    }
