android - 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，所以我这样做是为了你，但我知道这是不合适的。

原因是当app最小化，或者在后台时，通知投递到Android notification delivered to Android notification tray。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。
