Hi Bruno,
Please make sure you have the account authenticator xml added in you application and authenticator service in AndroidManifest.xml. Please refer the document links to which are given in README.md.

Hi @Ruqiya-Kaladgi!
The MASAuthenticatorService is allready added to the AndroidManifest, i think it might have a different cause, thanks anyway.
This is the top offensor crash in or app, we have 10k+ crashs in the last 7 days and 98% of them are from Samsung devices with Android 9.
Any help is much appreciated.

Hi @bruno-cunha
Please give details on the use case.
ADB logs would really help.
Is your app being installed first time on the devices?
The failure could occur if you already have an app with account manager setup and you try to install same app with different signature.

@Ruqiya-Kaladgi, unfortunately I haven’t been able to to reproduce the error, all I have is the report on fabric.

@bruno-cunha
Is your app being used afresh by the users or is it an ugrade to previous version?
Is it possible to give details like on which Device and Android version the issue is happening?

[bruno-cunha]

@Ruqiya-Kaladgi
The app is an update from previous versions.

Those are the devices with most occurrences in the last 90 days, all of the them with Android 9:

Device	%
Galaxy J6	11%
Galaxy S8	11%
Galaxy J6+	8%
Galaxy J7 Pro	8%
Galaxy J8	7%
Galaxy S8+	7%
Galaxy J4+	4%
Galaxy J7 Prime 2	3%
Galaxy Note8	3%
Galaxy S9+	2%

Is your app available to everyone, so we could get it installed and see?
