Updating Android studios to version 2.2, the following error will appear in the compiler version, and why? I don’t understand, ask permission, thanks.

Updating to the latest version of AndroidStudio no longer occurs, is this a tool error?

Answer 1

Have you tried using the latest version in the build.gradle file?

 dependencies { classpath 'com.android.tools.build:gradle:2.2.1' }
