Gradle keep asking for update and demotion?

Question

I keep getting “Gradle Sync Error”, so I checked version 1.8. updated to 1.10, then he said that I need 1.9, so I lowered the rating to 1.9, said I need 1.8, when I go down to 1.8, he says I need 1.9.

Answer 1

Gradle 1.10 is not yet supported in AS, the Android Tools development team is working on this and will probably be available in a future version.

Now make sure all your build.gradle files in the project using gradle 1.9 as a dependency

  buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.7.+' } } 

Update:

Gradle 1.10 is now supported in Android studio after the release of 0.4.3, so in the future you can start using the 1.10 plugin with 0.8.+ In your classpath like this

 classpath 'com.android.tools.build:gradle:0.8.+'
