Error: AGPBI: Program type already present: com.google.android.gms.auth.api.signin.internal.zzg

Question

In my Adrdoi app, where I use Google Login and Firebase Cloud Messaging, I get this error message:

AGPBI: {"kind":"error","text":"Program type already present: com.google.android.gms.auth.api.signin.internal.zzg","sources":[{}]}

Does that mean that the google auth lib was already used somewhere else? Whats that from?

Solution 1

I had the same problem.

Changed by changing

implementation 'com.google.firebase:firebase-auth:11.0.6'

to

implementation 'com.google.firebase:firebase-auth:11.2.2'

The issue happened after adding the firebase plugin at Android 3.

Android Plugin version automatically adds

implementation 'com.google.firebase:firebase-auth:11.0.6' 

but we need to change the version to 11.2.2

Solution 2

Go back to 11.2.2 version of firebase.

For example:

From:

'com.google.firebase:firebase-core:11.4.0'

to

'com.google.firebase:firebase-core:11.2.2'

UPDATE

Even 11.6.0 of firebase has been released, this problem still exist. I found out adding

compile 'com.google.firebase:firebase-core:11.6.0'    
compile 'com.google.android.gms:play-services-location:11.6.0'  

problem disappears.

Solution 3

FWIW I had a similar error with a different library I use in my app, and the workaround for me was setting android.enableD8=false in gradle.properties.

Or upgrading from AGP 3.0.0-beta3 to beta6.

Already Android Studio 3.0.0-Beta 6. Also included android.enableD8=false in gradle.proterties

but, isn't android.enableD8=false deprecated?

[Eric]

@NarendraJi yes, but it wasn't deprecated in September 2017 when I wrote this answer. I'm not sure when this issue was fixed but I'm no longer having the issue and I'm on AGP 3.2.0-alpha08

[Martin Zeitler]

The option 'android.enableD8' is deprecated and should not be used anymore. Use 'android.enableD8=true' to remove this warning.

I had the same problem ,I had 'com.google.android.gms:play-services-auth:15.0.0' dependency . Then I just removed this dependency and the problem was solved/
