我刚刚使用主题消息传递实现了 firebase 云消息传递 pushNotification。收到通知,但 MyFirebaseMessagingService 未正常工作。它传递的消息与云消息一样。
完成云消息功能。 创建服务名称 MyFirebaseMessagingService 并使用 FirebaseMessagingService 进行扩展。 将服务添加到 list 。
这是我的 FirebaseMessagingService 类。
@Override
public void onDeletedMessages() {
super.onDeletedMessages();
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String messageTitle = remoteMessage.getNotification().getTitle();
String clickAction = remoteMessage.getNotification().getClickAction();
Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/" + R.raw.hollow);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, getString(R.string.default_notification_channel_id))
.setSmallIcon(R.mipmap.ic_launcher_round)
.setContentTitle("New Notification")
.setSound(soundUri)
.setContentText(messageTitle);
Intent resultIntent = new Intent(clickAction);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setPriority(Notification.PRIORITY_HIGH);
if (Build.VERSION.SDK_INT >= 21) builder.setVibrate(new long[0]);
int mNotificationId = (int) System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(mNotificationId, builder.build());
}
我的 list 文件:-
<service
android:name=".MyFirebaseMessagingService"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="@string/default_notification_channel_id" />
最佳答案
在发送云消息的同时,您还必须订阅要接收通知的主题,例如。
FirebaseMessaging.getInstance().subscribeToTopic("general")
.addOnCompleteListener(task -> {
if (task.isSuccessful())
Toast.makeText(this, "Subs-Successful", Toast.LENGTH_SHORT).show();
else
Toast.makeText(this, "Subs NOT Successful", Toast.LENGTH_SHORT).show();
});
在此我订阅了一般主题,并且只会收到关于这个主题的消息,就像这个一样。
希望这对我有帮助......对我有用!
