Gradle: More than one variant of project :myLib matches the consumer attributes

Solution 1:

The google-services gradle plugin is made to work with Google Play Services and Firebase 15+, but you're using it with version 12.0.1.

The solution is to either:

• Upgrade your Play Services and Firebase dependencies to version 15+ (note that they have different versions now)
• Cancel your google-services upgrade to 3.3.0 until you upgrade to 15+, that is, downgrading the gradle plugin to version 3.2.1.

EDIT 1: There's a known issue about using google-services 3.3 in multimodule apps. That means downgrading to google-services to 3.2.1 may be your only option until a new version that fixes the bug is released.

EDIT 2: The bug mentioned above has been fixed in the version 4.0.1 of the google-services gradle plugin! (and the version 4.0.2 also fixes an NPE that occurred in some cases)

BTW, you should move to FCM. GCM will stop working in a not too distant future.

Solution 2:

I got this error when I use google-services:3.3.0.

Downgrade to classpath 'com.google.gms:google-services:3.2.1' in your project .gradle.

It should solve the issue.

Update: It should probably not occur in the current versions.

Solution 3:

Faced with similar issue while upgrading to 3.3.1

Fixed it by downgrading to 3.2.1

We can use firebase version >=15 with 3.2.1

Solution 4:

Below steps worked for me ---

1. Go to the android/build.gradle file.
2. Search for jcentre() method.
3. Shift all the jcenter() methods to the bottom inside its block.
