Multiple dex files define Lcom/google/android/gms/auth/api/signin/internal/zzg

While running android application I am getting the above error,

I checked this SO and many other posts on the net, no help :(

I have dealt with this already, in the android guide it calls out this line

compile 'com.google.android.gms:play-services-auth:9.2.1'

when I had 9.2.1 version I had the same issue because i am installing a newer version of play services in my emulator. So I changed it to the current for my version which is 11.0.4

compile 'com.google.android.gms:play-services-auth:11.0.4

that solved it for me

following this guide helped me solve the Multiple dex issues

Hello there, This error basically happens if the google plugins are referring to different versions of play-services.

if this occurs on native android just change the build.gradle(Module: app) file to refer to same version number like 11.6.0 or 11.6.2 but nothing like 11.+,

literally every single dependency that starts with com.google.... needs to be overwritten with just one version only.

if you are developing using react native then the guide suggested by @raduflp is a very good one to override all the dependencies to point to one version,.

if you are using a framework like flutter then open the yourapp/android folder in android studio and you will see build.gradle file for the google plugins like firebase auth, messaging etc and you can edit each one to refer to one version of dependency and this should solve your problem.

Regards, Mahi
