All com.android.support libraries must use the exact same version specification

Question

After updating to android studio 2.3 I got this error message. I know it\'s just a hint as the app run normally but it\'s really strange.

All com.andr

Answer 1

I ran ./gradlew tasks --all and checked for dependencies that were a different version from the targeted version (25.3.1). You'll get something like this:

In this case, I was targeting 25.3.1, and had some dependencies targeting different versions when I ran this command. The trick is to identify the dependencies in this list that are targeting previous versions, and overriding that by importing the most recent version of the dependency in Gradle.
