[英]Firebase Push notification is not playing sound when app is in background
[英]Android Push notification sound is played only when app is in foreground but not playing sound when app is in background
我在代码下方使用 FCM 推送通知,以便在收到通知时播放声音
public void playNotificationSound() {
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(mContext, notification);
r.play();
} catch (Exception e) {
e.printStackTrace();
}
}
我正在调用此 OnMessageReceived 方法,但声音仅在应用程序处于前台时播放,而不是在应用程序处于后台时播放
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.e(TAG, "From: " + remoteMessage.getFrom());
if (remoteMessage == null)
return;
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody());
handleNotification(remoteMessage.getNotification().getBody());
}
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());
try {
JSONObject json = new JSONObject(remoteMessage.getData().toString());
handleDataMessage(json);
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
}
private void handleNotification(String message) {
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
// app is in foreground, broadcast the push message
Intent pushNotification = new Intent(config.PUSH_NOTIFICATION);
pushNotification.putExtra("message", message);
LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
// play notification sound
NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
notificationUtils.playNotificationSound();
}else if (NotificationUtils.isAppIsInBackground(getApplicationContext())){
// If the app is in background, firebase itself handles the notification
NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
notificationUtils.playNotificationSound();
}
}
由于在发送通知对象时不会调用onMessageReceived()
,因此我创建了一个 BroadcastReceiver 来在通知到达时处理它:
public class NotificationReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
playNotificationSound(context);
}
public void playNotificationSound(Context context) {
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(context, notification);
r.play();
} catch (Exception e) {
e.printStackTrace();
}
}
并将其添加到清单中。 Receiver 负责播放通知铃声。
<receiver
android:name=".notification.NotificationReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</receiver>
您需要在高级设置下的 Firebase Notification Composer 中启用声音。 :)
private void sendNotification(String messageBody, Intent intent) {
//intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent/*.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)*/,
PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentIntent(pendingIntent);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);//<--
Bitmap bitmap = getBitmapfromUrl(postImageUrl);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_recive)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.notification_recive))
.setContentTitle(postTitle + "")
.setStyle(new NotificationCompat.BigPictureStyle()
.setSummaryText(postTitle + "")
.bigPicture(bitmap))
.setContentText(messageBody)
.setLights(getResources().getColor(R.color.blue),1000,1500)
.setAutoCancel(true)
.setSound(defaultSoundUri)//<--
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
您需要使用元数据将默认频道设置到您的Manifest.xml
中,如下所示:
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="NAME_OF_YOUR_DEFAULT_CHANNEL" />
您已经拥有 onMessageReceived 方法,firebase 在应用程序处于后台时发送 remoteMessage.getData() 类型。 并且 remoteMessage.getNotification() 将为空。 所以声音只在应用程序在前台时播放,当应用程序在后台时不播放。 你需要添加
if (remoteMessage.getData().size() > 0) {
Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());
try {
JSONObject json = new JSONObject(remoteMessage.getData().toString());
handleNotification(json.getString("msg");//I am assuming message key is msg
handleDataMessage(json);
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
