无法在模拟器上获取 FIS 身份验证令牌

Question

Im using firebase for sending notification.

my version of firebase-messages is:

implementation ("com.google.firebase:firebase-messaging:20.0.0") 

I configure my firebase with google-service.json

The weird issue that when I run my app on the emulator on browserstack I get this error: Failed to get FIS auth token and java.util.concurrent.ExecutionException: com.google.firebase.installations.FirebaseInstallationsException

it seems it comes from the installation

but when I run it on physical android device I don't get the error and I succeed to get Token... I checked only on one physical device.In addition I checked on like 10 different emulators devices (include my physical device just on emulator) and they all show the same error.

I tried to change the firebase-messaging to version 20.1.0 but it didn't change anything... I don't understand what might be the issue for that especially that it worked before and I didn't change anything and why it happens only on emulator and not on physical device

Answer 1

From my understanding, BrowserStack offers real devices. In case the issue doesn't appear on a local device, I would suggest reaching out to the BrowserStack Support team at support@browserstack.com and they should be able to throw some lights towards this.
