If you use different version of play services libraries, you will get this error.

For example, below entries in build.gradle file cause the error as versions are different.

implementation 'com.google.android.gms:play-services-maps:11.4.2'
implementation 'com.google.android.gms:play-services-location:11.6.0'

To fix the issue use same versions.

implementation 'com.google.android.gms:play-services-maps:11.6.0'
implementation 'com.google.android.gms:play-services-location:11.6.0'

If you are using more than one libraries of firebase then make sure that the version are same   Before    compile  com google firebase firebase-database 9 2 0      compile  com google firebase firebase-storage 9 2 0      compile  com firebaseui firebase-ui-database 0 4 0      compile  com squareup picasso picasso 2 5 2      compile  com google firebase firebase-auth 9 0 2   After   compile  com google firebase firebase-database 9 2 0      compile  com google firebase firebase-storage 9 2 0      compile  com firebaseui firebase-ui-database 0 4 0      compile  com squareup picasso picasso 2 5 2      compile  com google firebase firebase-auth 9 2 0    in my case i have used auth with 9 0 2  So i changed to 9 2 0

Well  the short answer is  update your library version  Android studio will tell you that there is a new version of it with a message like      A newer version of com google firebase firebase-core than 14 0 4 is   available  16 0 4   Just move to that line  press Alt   Enter and select Change to X X where X X is the newer version   This way  you can update all your libraries  Repeat the process with all the libraries and you are done

This error occurs only due to the difference in version  Whenever this kinda error occurs try to change the SDK versions  Gradle Build versions  or dependency version  If you are using targetSdkVersion   26 compileSdkVersion   26  com android tools build gradle 3 6 3   then add this version for firebase dependencies  implementation  com google firebase firebase-core 11 6 0  implementation  com google firebase firebase-database 11 6 0  implementation  com google firebase firebase-auth 11 6 0   It works

I had such a similar error when i was recently upgrading my play service dependency  It seems to occur when you leave out updating the firebase dependencies that correspond to the version of play services you use  I beleive this is the most recent update of these dependencies  Here is what the two versions of my dependencies were   Error version of dependencies  compile  com google firebase firebase-appindexing 10 0 1  compile  com google android gms play-services-maps 10 0 1  compile  com google android gms play-services-places 10 0 1  compile  com google android gms play-services-location 10 0 1  compile  com google firebase firebase-auth 9 8 0  compile  com google firebase firebase-database 9 8 0  compile  com firebaseui firebase-ui-database 1 0 1  compile  com google firebase firebase-storage 9 8 0    Working version of dependencies      compile  com google firebase firebase-appindexing 10 0 1  compile  com google android gms play-services-maps 10 0 1  compile  com google android gms play-services-places 10 0 1  compile  com google android gms play-services-location 10 0 1  compile  com google firebase firebase-auth 10 0 0  compile  com google firebase firebase-database 10 0 0  compile  com firebaseui firebase-ui-database 1 0 1  compile  com google firebase firebase-storage 10 0 0       Google seems to move play service updates along with firebase updates these days  Hopes this saves a few souls out there
