gcm token will sometimes return to the "MESSENGER".

[fwith]

Recently.. Sometimes gcm token, it will be returned to the "MESSENGER".

Gcm token to retrieve them as follows:

InstanceID instanceID = InstanceID.getInstance(getApplicationContext());
String token = instanceID.getToken(getString(R.string.gcm_defaultSenderID), GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

Most of the cases are sometimes good, but sometimes returned as a token of unknown "MESSENGER".

Are you sure about this? Please tell us if there is a solution.

Same here, only using the Firebase API:
FirebaseInstanceId.getInstance().getToken()

We've also seen the gcm token returned as "AP".

Same here, We also have seen it sometimes return the package name for the app, as well as sometimes the string "null", which is well, unexpected.

[rajool]

Same here,
We saw this on the original instance_id service (As we did not switch to Firebase yet)

Does anybody know solution for this issue?

Same, detecting "MESSENGER" using the Firebase API.

Hi All, this is a known issue and a fix is in progress, I will respond here once the fix is out.

[srihards]

How long for the issue to be resolved? Our users are getting really angry about not receiving notifications.

[traunay]

Okay,
So this thing is still going with no fix after a month? I just ran few tests and it happened on devices with 4.2 installed (which I still support)

Hi, All.
The fix is out? and i have a just simple question.
How can we apply to fixed thing to exiting app if this issue is fiexd?
Will it be done by updating Google Play Service on Android Studio?

[tpurtell]

I am seeing this behavior too.

[dcarey]

Me too

@kroikie Your message says this is a known issue. Can you please elaborate? Is there a bug filed in the AOSP that I can star? Is there any workaround or even a complete problem definition? It's been a while since you took assignment of this issue. If you are busy, maybe another contributor can take this on and get it closed.
