I am working on App in which I am required to show notification. For notification, i am using FireBase Cloud Messaging (FCM). I am able to get Notification when app is in background.
But when I click on notification, it redirect to home.java page. I want it to redirect to Notification.java page.
So,please tell me how to specify Activity in on Click of notification. I am using two services:
1.)MyFirebaseMessagingService
2.)MyFirebaseInstanceIDService
This is my code sample for onMessageReceived() method in MyFirebaseMessagingService class.
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FirebaseMessageService";
Bitmap bitmap;
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
}
/**
* Create and show a simple notification containing the received FCM message.
*/
private void sendNotification(String messageBody, Bitmap image, String TrueOrFalse) {
Intent intent = new Intent(this, Notification.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("Notification", TrueOrFalse);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setLargeIcon(image)/*Notification icon image*/
.setContentTitle(messageBody)
.setStyle(new NotificationCompat.BigPictureStyle()
.bigPicture(image))/*Notification with Image*/
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
/*
*To get a Bitmap image from the URL received
* */
public Bitmap getBitmapfromUrl(String imageUrl) {
try {
URL url = new URL(imageUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap bitmap = BitmapFactory.decodeStream(input);
return bitmap;
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}
AndroidManifest.xml
Your FirebaseMessagingService.java file onMessageReceived method:
Your cloud function/server code for notification:
Open MyFirebaseMessagingService.java file
inside that file there is a sendNotification() method, there you have to specify your activity you need to navigate to in the Intent as shown below
if you are sending multiple notification and you want to navigate to different Activities on click of a particular Notification you can use any conditional statement to achieve it, my suggestion is to use a switch case as shown below
Using this logic you can open a specific activity on Notification click in FCM. This works perfectly for me. Thanks
When app is in background, Intent must be delivered at your launcher activity . So it opens your Launcher activity. Now you check if there is data in Intent in launcher activity then start your required Activity.
With FCM, you can send two types of messages to clients:
1. Notification messages: sometimes thought of as "display messages."
FCM automatically displays the message to end-user devices on behalf of the client app. Notification messages have a predefined set of user-visible keys.
2. Data messages: which are handled by the client app.
Client app is responsible for processing data messages. Data messages have only custom key-value pairs.
According to FCM document Receive Messages in an Android App
Set
click_action
in the notification payload:So, if you want to process the messages arrived in the background, you have to send
click_action
with message.click_action
is a parameter of the notification payloadIf you want to open your app and perform a specific action, set
click_action
in the notification payload and map it to an intent filter in the Activity you want to launch.For example, set
click_action
toOPEN_ACTIVITY_1
to trigger an intent filter like the following:FCM payload looks like below:
