I'm working on an android device which runs 5.1.1, and it's rooted. My plan is to implement firebase message service in the application I'm building which should run on the device. But initially It didn't have google play services so I installed in manually with 11.7.44 version. But the problem I'm getting now is, it doesn't get the firebase token still; I'm getting the following message:
FirebaseInstanceId: background sync failed: AUTHENTICATION_FAILED
Note that the device is connected to the internet, and also the program runs perfectly on normal android phones.
I'm suspecting whether I should install some other applications in order to run FCM correctly.
any ideas on that?
Thanks.
