FirebaseInstanceId does not exist anymore

Question

I just did an upgrade to all my Firebase dependencies and I have an issue, FirebaseInstanceId is not recognized anymore. I have used it to get the token id like this:

String tokenId = FirebaseInstanceId.getInstance().getToken();

This is the error:

Cannot resolve symbol 'FirebaseInstanceId'

Here is my build.gradle file:

//Firebase
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-firestore:17.0.1'

//FirebaseUI
implementation 'com.firebaseui:firebase-ui-auth:4.0.0'
implementation 'com.firebaseui:firebase-ui-database:4.0.0'
implementation 'com.firebaseui:firebase-ui-firestore:4.0.0'

How can I get the token id using the latest dependencies?

Solution 1

add the following to the build.gradle file:

 implementation 'com.google.firebase:firebase-messaging:17.0.0'
 implementation 'com.google.firebase:firebase-core:16.0.0'

more info here:

https://firebase.google.com/docs/cloud-messaging/android/client#set-up-firebase-and-the-fcm-sdk

Solution 2

I also faced the same problem. From the doc, it says FirebaseInstanceId is no longer available and says to use FirebaseMessaging.getInstance().token as below

FirebaseMessaging.getInstance().token.addOnCompleteListener(OnCompleteListener { task ->
    if (!task.isSuccessful) {
        Log.w(TAG, "Fetching FCM registration token failed", task.exception)
        return@OnCompleteListener
    }

    // Get new FCM registration token
    val token = task.result
})

Solution 3

I was also facing the same problem. Actually, FirebaseInstanceId has been shut down, replaced with Firebase Installation.

Try:

FirebaseInstallations.getToken();

Solution 4

Add into Gradle:

  implementation 'com.google.firebase:firebase-messaging:22.0.0'

  implementation 'com.google.firebase:firebase-core:19.0.0'

Then add the following code to get the token:

public static String returnMeFCMtoken() {
        final String[] token = {""};
        FirebaseMessaging.getInstance().getToken().addOnCompleteListener(new OnCompleteListener<String>() {
            @Override
            public void onComplete(@NonNull Task<String> task) {
                if(task.isComplete()){
                    token[0] = task.getResult();
                    Log.e("AppConstants", "onComplete: new Token got: "+token[0] );

                }
            }
        });
        return token[0];
    }

FirebaseMessaging.getInstance().getToken() is an asynchronous call, so return token[0] would return "". you need a way to wait for the response
