Deep Link with Push Notification - FCM - Android

Question

What I want: I want to send push notification to users. When user tap on that notification, user should navigate to specific activity.

What I did: I created one deep link in Firebase console. I implemented FirebaseInstanceIdService & FirebaseMessagingService as well. I'm able to catch Firebase message which I sent from Firebase console.

What is the issue: I'm not able to catch the dynamic link what I have created in Firebase console.

My code is like below.

MyFirebaseInstanceIDService.java

    public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {      private final String TAG = "MyFirebaseInstanceID";      @Override     public void onTokenRefresh() {          String refreshedToken = FirebaseInstanceId.getInstance().getToken();          Log.e(TAG, "Refreshed token: " + refreshedToken);     } } 

MyFirebaseMessagingService.java

    public class MyFirebaseMessagingService extends FirebaseMessagingService {      private final String TAG = "MyFbaseMessagingService";      @Override     public void onMessageReceived(RemoteMessage remoteMessage) {          String message = remoteMessage.getNotification().getBody();          Log.e(TAG, "\nmessage: " + message);          sendNotification(message);     }      private void sendNotification(String message) {          Intent intent = new Intent(this, TestDeepLinkActivity.class);         intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);          Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);          PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);          NotificationCompat.Builder builder = new NotificationCompat.Builder(this)                 .setAutoCancel(true)                 .setContentTitle("FCM Test")                 .setContentText(message)                 .setSound(defaultSoundUri)                 .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)                 .setContentIntent(pendingIntent);          NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);          manager.notify(0, builder.build());     } }

Solution:

• I have to add intent-filter in an activity in manifest file to which I want to go, on-tapping of push notification. This notification will have some url which is being called deeplink in Android Terminology. You can refer below link for more about deeplink.

https://developer.android.com/training/app-links/deep-linking

• I was using these two links as a deeplink: "www.somedomain.com/about" & "www.somedomain.com/app".

• Please do not add http or https in intent-filter, they are not supported. Chekout this conversation for more clarification. I'm putting an image of that chat as well, If in case in future the link gets expire.

• Please refer below code for how I'm passing deeplink to NotificationManager. intent-filter aumatically intercept and launch that particular activity.

MyFirebaseMessagingService.java

public class MyFirebaseMessagingService extends FirebaseMessagingService {      @Override     public void onMessageReceived(RemoteMessage remoteMessage) {          Map<String, String> data = remoteMessage.getData();          String title = data.get("title");         String message = data.get("message");         String deepLink = data.get("deepLink");          Notification notification = new Notification();         notification.setTitle(title);         notification.setMessage(message);         notification.setDeepLink(deepLink);          sendNotification(this, title, message, deepLink);     }      public static void sendNotification(Context context, String title, String message, String deepLink) {          NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);          if (Build.VERSION.SDK_INT >= 26) {             NotificationChannel notificationChannel = new NotificationChannel("any_default_id", "any_channel_name",                     NotificationManager.IMPORTANCE_HIGH);             notificationChannel.setDescription("Any description can be given!");             notificationManager.createNotificationChannel(notificationChannel);         }          Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);          NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)                 .setAutoCancel(true)                 .setSound(defaultSoundUri)                 .setSmallIcon(R.mipmap.ic_launcher)                 .setPriority(android.app.Notification.PRIORITY_MAX)                 .setDefaults(android.app.Notification.DEFAULT_ALL)                 .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher));          Intent intent = new Intent();          intent.setAction(Intent.ACTION_VIEW);         intent.setData(Uri.parse(deepLink));         intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);          PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);          notificationBuilder                 .setContentTitle(title)                 .setContentText(message)                 .setContentIntent(pendingIntent);          notificationManager.notify(0, notificationBuilder.build());     } } 

AndroidManifest.xml

<activity     android:name=".mvp.view.activity.ActivityName"     android:label="@string/title_activity_name"     android:theme="@style/AppTheme.NoActionBar">      <intent-filter>         <action android:name="android.intent.action.VIEW" />          <category android:name="android.intent.category.DEFAULT" />         <category android:name="android.intent.category.BROWSABLE" />          <data             android:host="www.somedomain.com"             android:path="/about"             android:scheme="app" />     </intent-filter>      <intent-filter>         <action android:name="android.intent.action.VIEW" />          <category android:name="android.intent.category.DEFAULT" />         <category android:name="android.intent.category.BROWSABLE" />          <data             android:host="www.somedomain.com"             android:path="/contact"             android:scheme="app" />     </intent-filter> </activity> 

Extra:

• If you want to receive some more data(i.e userId or loanId) in that activity, you can pass it to while sending push notification from your server(i.e back-end or web based dashboard). You can do like below.

  {  "data": {  "userId": "65431214564651251456",  "deepLink": "www.somedomain.com/app",  "title": "This is title!",  "message": "This is message!"  }, "to": "FCM token here" } 

• Important: Below JSON will not work, this is for reference only. This is also nowhere mentioned in documentation. So kindly take care of it. Correct JSON is above.

{     "to": "FCM Token here",         "notification": {             "Body": "This week’s edition is now available.",             "title": "NewsMagazine.com",             "icon": "new"         },         "data": {             "title": "This is title!",             "message": "This is message!"     } } 

• You can receive extra data(i.e userId or loanId) in method onMessageReceived of MyFirebaseMessagingService class like below.

String userId = data.get("userId"); intent.putExtra(Intent.EXTRA_TEXT, userId); 

• And in that activity you can write like below in onCreate method.

Intent intent = getIntent(); if (intent != null) {     String intentStringExtra = intent.getStringExtra(Intent.EXTRA_TEXT);     if (intentStringExtra != null) {         userId = intentStringExtra;     } }
