通知声音在安卓 10 中无法播放

Question

我正在通过Firebase Cloud Messaging 发送通知，但是声音和振动没有在装有Android 10的手机上播放，但声音正在装有Android 9的Android模拟器中播放。由于它是一个模拟器，我不能说它是否有振动。

我已经检查了其他StackOverflow帖子，但无法获得解决方案。

这是我的代码-

import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Build;
import android.util.Log;
import androidx.core.app.NotificationCompat;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
/**
* NOTE: There can only be one service in each app that receives FCM messages. If multiple
* are declared in the Manifest then the first one will be chosen.
* <p>
* In order to make this Java sample functional, you must remove the following from the Kotlin messaging
* service in the AndroidManifest.xml:
* <p>
* <intent-filter>
* <action android:name="com.google.firebase.MESSAGING_EVENT" />
* </intent-filter>
*/
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
/**
* Called when message is received.
*
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

Log.d(TAG, "From: " + remoteMessage.getFrom());
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());

}
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}

}

private void handleNow() {
Log.d(TAG, "Short lived task is done.");
}

private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = getString(R.string.default_notification_channel_id);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.logo)
.setContentTitle("Brain Filter")
.setColor(getResources().getColor(R.color.colorAccent))
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

我还在清单中添加了振动和互联网权限.xml并在推送任何通知时始终在 Firebase 控制台中启用声音。

卸载您的应用程序并重新安装将解决此问题。

这些设置是在首次创建通道时设置的，然后不会修改，除非您通过全新安装或清除数据手动执行此操作。
