FirebaseInstanceIdService is deprecated

AndroidFirebaseFirebase Cloud-Messaging

Android Problem Overview

Hope all of you aware of this class, used to get notification token whenever firebase notification token got refreshed we get the refreshed token from this class, From following method.

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);
}

To use this as i want to implement FCM, I extended MyClass from FirebaseInstanceIdService

But, Showing that FirebaseInstanceIdService is deprecated

Does anybody know this?, What method or class i should use instead of this to get refreshed token as this is deprecated.

I'm using : implementation 'com.google.firebase:firebase-messaging:17.1.0'

I checked the document for same there is nothing mentioned about this. : FCM SETUP DOCUMENT

UPDATE

This issue has been Fixed.

As Google deprecated the FirebaseInstanceService,

I asked the question to find the way and i get to know that We can get the Token from FirebaseMessagingService,

As before, when i asked the Question Documents were not updated but Now Google docs updated so for more info, Refer this google doc : FirebaseMessagingService

OLD From : FirebaseInstanceService (Deprecated)

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);
}

NEW From : FirebaseMessagingService

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Log.d("NEW_TOKEN",s);
}

Thanks.

Update 11-12-2020

Now FirebaseInstanceId is also deprectaed

Now we need to use FirebaseMessaging.getInstance().token

SAMPLE CODE

        FirebaseMessaging.getInstance().token.addOnCompleteListener {
            if(it.isComplete){
                firebaseToken = it.result.toString()
                Util.printLog(firebaseToken)
            }
        }

Yes FirebaseInstanceIdService is deprecated >FROM DOCS :- This class was deprecated. In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed.

No need to use FirebaseInstanceIdService service to get FCM token You can safely remove FirebaseInstanceIdService service

Now we need to @Override onNewToken get Token in FirebaseMessagingService

SAMPLE CODE

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onNewToken(String s) {
        Log.e("NEW_TOKEN", s);
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        Map<String, String> params = remoteMessage.getData();
        JSONObject object = new JSONObject(params);
        Log.e("JSON_OBJECT", object.toString());

        String NOTIFICATION_CHANNEL_ID = "Nilesh_channel";

        long pattern[] = {0, 1000, 500, 1000};

        NotificationManager mNotificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "Your Notifications",
                    NotificationManager.IMPORTANCE_HIGH);

            notificationChannel.setDescription("");
            notificationChannel.enableLights(true);
            notificationChannel.setLightColor(Color.RED);
            notificationChannel.setVibrationPattern(pattern);
            notificationChannel.enableVibration(true);
            mNotificationManager.createNotificationChannel(notificationChannel);
        }

        // to diaplay notification in DND Mode
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = mNotificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID);
            channel.canBypassDnd();
        }

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);

        notificationBuilder.setAutoCancel(true)
                .setColor(ContextCompat.getColor(this, R.color.colorAccent))
                .setContentTitle(getString(R.string.app_name))
                .setContentText(remoteMessage.getNotification().getBody())
                .setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.drawable.ic_launcher_background)
                .setAutoCancel(true);


        mNotificationManager.notify(1000, notificationBuilder.build());
    }
}

#EDIT

>You need to register your FirebaseMessagingService in manifest file like this

    <service
        android:name=".MyFirebaseMessagingService"
        android:stopWithTask="false">
        <intent-filter>
            
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

#how to get token in your activity

>.getToken(); is also deprecated if you need to get token in your activity than Use getInstanceId ()

Now we need to use getInstanceId () to generate token

getInstanceId () Returns the ID and automatically generated token for this Firebase project.

This generates an Instance ID if it does not exist yet, which starts periodically sending information to the Firebase backend.

Returns

  • Task which you can use to see the result via the InstanceIdResult which holds the ID and token.

SAMPLE CODE

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this,  new OnSuccessListener<InstanceIdResult>() {
     @Override
     public void onSuccess(InstanceIdResult instanceIdResult) {
           String newToken = instanceIdResult.getToken();
           Log.e("newToken",newToken);

     }
 });

##EDIT 2

Here is the working code for kotlin

class MyFirebaseMessagingService : FirebaseMessagingService() {

    override fun onNewToken(p0: String?) {

    }

    override fun onMessageReceived(remoteMessage: RemoteMessage?) {


        val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
        val NOTIFICATION_CHANNEL_ID = "Nilesh_channel"

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val notificationChannel = NotificationChannel(NOTIFICATION_CHANNEL_ID, "Your Notifications", NotificationManager.IMPORTANCE_HIGH)

            notificationChannel.description = "Description"
            notificationChannel.enableLights(true)
            notificationChannel.lightColor = Color.RED
            notificationChannel.vibrationPattern = longArrayOf(0, 1000, 500, 1000)
            notificationChannel.enableVibration(true)
            notificationManager.createNotificationChannel(notificationChannel)
        }

        // to diaplay notification in DND Mode
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val channel = notificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID)
            channel.canBypassDnd()
        }

        val notificationBuilder = NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)

        notificationBuilder.setAutoCancel(true)
                .setColor(ContextCompat.getColor(this, R.color.colorAccent))
                .setContentTitle(getString(R.string.app_name))
                .setContentText(remoteMessage!!.getNotification()!!.getBody())
                .setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.drawable.ic_launcher_background)
                .setAutoCancel(true)


        notificationManager.notify(1000, notificationBuilder.build())

    }
}

firebaser here

Check the reference documentation for FirebaseInstanceIdService:

> This class was deprecated. > >In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed.

Weirdly enough the JavaDoc for FirebaseMessagingService doesn't mention the onNewToken method yet. It looks like not all updated documentation has been published yet. I've filed an internal issue to get the updates to the reference docs published, and to get the samples in the guide updated too.

In the meantime both the old/deprecated calls, and the new ones should work. If you're having trouble with either, post the code and I'll have a look.

Solution 3 - Android

And this:

FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken()

suppose to be solution of deprecated:

FirebaseInstanceId.getInstance().getToken()

EDIT

FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken() can produce exception if the task is not yet completed, so the method witch Nilesh Rathod described (with .addOnSuccessListener) is correct way to do it.

Kotlin:

FirebaseInstanceId.getInstance().instanceId.addOnSuccessListener(this) { instanceIdResult ->
        val newToken = instanceIdResult.token
        Log.e("newToken", newToken)
    }

Solution 4 - Android

Simply call this method to get the Firebase Messaging Token

public void getFirebaseMessagingToken ( ) {
        FirebaseMessaging.getInstance ().getToken ()
                .addOnCompleteListener ( task -> {
                    if (!task.isSuccessful ()) {
                        //Could not get FirebaseMessagingToken
                        return;
                    }
                    if (null != task.getResult ()) {
                        //Got FirebaseMessagingToken
                        String firebaseMessagingToken = Objects.requireNonNull ( task.getResult () );
                        //Use firebaseMessagingToken further
                    }
                } );
    }

The above code works well after adding this dependency in build.gradle file

implementation 'com.google.firebase:firebase-messaging:21.1.0'

Note: This is the code modification done for the above dependency to resolve deprecation. (Working code as of 9th May 2021)

Solution 5 - Android

FirebaseinstanceIdService is deprecated. So have to use "FirebaseMessagingService"

Sea the image please:

enter image description here

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        Log.e("NEW_TOKEN",s);
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
    }
}

Solution 6 - Android

Kotlin allows for even simpler code than what's shown in other answers.

To get the new token whenever it's refreshed:

class MyFirebaseMessagingService: FirebaseMessagingService() {

    override fun onNewToken(token: String?) {
        Log.d("FMS_TOKEN", token)
    }
    ...
}

To get the token from anywhere at runtime:

FirebaseInstanceId.getInstance().instanceId.addOnSuccessListener {
    Log.d("FMS_TOKEN", it.token)
}

Solution 7 - Android

In KOTLIN:- If you want to save Token into DB or shared preferences then override onNewToken in FirebaseMessagingService

override fun onNewToken(token: String) {
        super.onNewToken(token)
    }

Get token at run-time,use

FirebaseInstanceId.getInstance().instanceId
                        .addOnSuccessListener(this@SplashActivity) { instanceIdResult ->
                            val mToken = instanceIdResult.token
                            println("printing  fcm token: $mToken")
                        }

Solution 8 - Android

FCM implementation Class:

 public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
if(data != null) {
 // Do something with Token
  }
}
}
// FirebaseInstanceId.getInstance().getToken();
@Override
public void onNewToken(String token) {
  super.onNewToken(token);
  if (!token.isEmpty()) {
  Log.e("NEW_TOKEN",token);
 }
}
}

And call its initialize in Activity or APP :

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(
                instanceIdResult -> {
                    String newToken = instanceIdResult.getToken();
                }).addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Log.i("FireBaseToken", "onFailure : " + e.toString());
                    }
                });

AndroidManifest.xml :

  <service android:name="ir.hamplus.MyFirebaseMessagingService"
        android:stopWithTask="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

**If you added "INSTANCE_ID_EVENT" don't forget to disable it.

Solution 9 - Android

You have to use FirebaseMessagingService() instead of FirebaseInstanceIdService

Solution 10 - Android

And here the solution for C#/Xamarin.Android:

var token = await FirebaseInstallations.Instance.GetToken(forceRefresh: false).AsAsync<InstallationTokenResult>();

Solution 11 - Android

getInstance().getInstanceId() is also now deprecated and FirebaseMessaging is being used now.

FirebaseMessaging.getInstance().token.addOnCompleteListener { task ->
    if (task.isSuccessful) {
        val token = task.result
    } else {
        Timber.e(task.exception)
    }
}

Solution 12 - Android

First import import com.google.firebase.messaging.FirebaseMessaging; then Simply use FirebaseMessaging.getInstance().getToken().getResult(); instead of FirebaseInstanceId.getInstance().getToken().getresult()

That's it.

Solution 13 - Android

You can use service

<service android:name=".utils.fcm.MyFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
 </service>

public class MyFirebaseMessagingService extends FirebaseMessagingService{
           @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        Log.e("NEW_TOKEN = = == = = =",s);
    }

}

If you want to use in Activity

FirebaseMessaging.getInstance ().getToken ().addOnCompleteListener ( task -> {
                Log.e("spalsh",task.getResult());
                    });

Solution 14 - Android

Just Add This On build.gradle. implementation 'com.google.firebase:firebase-messaging:20.2.3'

Solution 15 - Android

Use FirebaseMessaging instead

 FirebaseMessaging.getInstance().getToken()
    .addOnCompleteListener(new OnCompleteListener<String>() {
        @Override
        public void onComplete(@NonNull Task<String> task) {
          if (!task.isSuccessful()) {
            Log.w(TAG, "Fetching FCM registration token failed", task.getException());
            return;
          }

          // Get new FCM registration token
          String token = task.getResult();

          // Log and toast
          String msg = getString(R.string.msg_token_fmt, token);
          Log.d(TAG, msg);
          Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });

Solution 16 - Android

For kotlin I use the following

val fcmtoken = FirebaseMessaging.getInstance().token.await()

and for the extension functions

public suspend fun <T> Task<T>.await(): T {
    // fast path
    if (isComplete) {
        val e = exception
        return if (e == null) {
            if (isCanceled) {
                throw CancellationException("Task $this was cancelled normally.")
            } else {
                @Suppress("UNCHECKED_CAST")
                result as T
            }
        } else {
            throw e
        }
    }

    return suspendCancellableCoroutine { cont ->
        addOnCompleteListener {
            val e = exception
            if (e == null) {
                @Suppress("UNCHECKED_CAST")
                if (isCanceled) cont.cancel() else cont.resume(result as T)
            } else {
                cont.resumeWithException(e)
            }
        }
    }
}

Solution 17 - Android

You can use this method in your activity , this worked for me.

private void registerInBackground() {
    FirebaseApp.initializeApp(SplashActivity.this);
    FirebaseMessaging.getInstance().getToken().addOnCompleteListener(new OnCompleteListener<String>() {
        @Override
        public void onComplete(@NonNull Task<String> task) {
            String token = task.getResult();
        }
    });
}

Solution 18 - Android

From com.google.firebase:firebase-bom:28.4.2 , the way to do it is as such:

FirebaseMessaging.getInstance().token.result

Since this is a Task, though, it doesn't return the value this way. You need to wait for it using a callback.

A nice way to solve it is via this:

@WorkerThread
fun <TResult> Task<TResult>.awaitForResult(): Task<TResult> {
    val countDownLatch = CountDownLatch(1)
    this.addOnCompleteListener {
        countDownLatch.countDown()
    }
    countDownLatch.await()
    return this
}

@WorkerThread
fun <TResult> Task<TResult>.awaitForResultOrNull(): Task<TResult>? {
    val task = awaitForResult()
    return if (task.isSuccessful)
        return task else null
}

So example usage:

val regId : String? = FirebaseMessaging.getInstance().token.awaitForResultOrNull()?.result
