打开应用时,应用未显示接收FCM的通知 [英] App not showing Notification receiving FCM when the app is Open
问题描述
当我从Firebase发送推送消息时,如果该应用处于后台或关闭状态,我会收到通知,但是当该应用处于打开状态时则不会...
When I send a push from Firebase, if the app is in background or closed, I'm receiving the notification, but when the app is open not...
调试我观察到它特别在onMessageReceived处在MyMessagingService中停止,所以我想我的问题与生成通知有关(或者可能与通知有关).
Debugging I've observed that it's stopping in MyMessagingService specifically at onMessageReceived, so I guess that my problem is in regards of generating the notification (or maybe the intent which goes with the notification).
我已经实现了该服务:
public class MyMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyMessagingService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
Log.d(TAG, "From: " + remoteMessage.getFrom());
if(remoteMessage!=null)
{
String id = null;
String title = null;
String message = null;
String launchPage = null;
if(remoteMessage.getNotification()!=null)
{
if(remoteMessage.getNotification().getTitle()!=null)
{
title = remoteMessage.getNotification().getTitle();
}
if(remoteMessage.getNotification().getBody()!=null)
{
message = remoteMessage.getNotification().getBody();
}
}
if(remoteMessage.getMessageId()!=null)
{
id = remoteMessage.getMessageId();
}
Log.e(TAG, "id: " + id);
Log.e(TAG, Consts.TITLE + title);
Log.e(TAG, Consts.MESSAGE + ": " + message);
// Check if message contains a data payload.
if (remoteMessage.getData()!=null && remoteMessage.getData().size() > 0)
{
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
if(remoteMessage.getData().containsKey(Consts.LAUNCH_PAGE))
{
launchPage = remoteMessage.getData().get(Consts.LAUNCH_PAGE);
}
Log.e(TAG, Consts.LAUNCH_PAGE + ": " + launchPage);
sendNotification(title, message, launchPage);
}
}
}
// [END receive_message]
/**
* Create and show a simple notification containing the received FCM message.
*
* @param messageBody FCM message body received.
*/
private void sendNotification(String title, String messageBody, String page)
{
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra(Consts.TITLE, title);
intent.putExtra(Consts.MESSAGE, messageBody);
if (launchPage != null)
{
intent.putExtra(Consts.LAUNCH_PAGE, launchPage);
}
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.status)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
} }
我的清单上有:
<!-- [START fcm_default_icon] -->
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/status" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/accent" />
<!-- [END fcm_default_icon] -->
<!-- [START fcm_default_channel] -->
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="@string/default_notification_channel_id"/>
<!-- [END fcm_default_channel] -->
<service
android:name=".controller.service.MyMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service
android:name=".controller.service.MyInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
关于在应用程序前台运行时如何生成通知的任何建议?
Any suggestion of how to generate the notification when the app is en foreground?
推荐答案
更改您的MyFirebaseMessagingService代码,
Change your MyFirebaseMessagingService code,
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
String channelId = "Default";
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody()).setAutoCancel(true).setContentIntent(pendingIntent);;
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId, "Default channel", NotificationManager.IMPORTANCE_DEFAULT);
manager.createNotificationChannel(channel);
}
manager.notify(0, builder.build());
}
}
