I installed Android Studio 0.5.1 and my project is not working any more. Error it provides is:
The project is using an unsupported version of Gradle. Pleas
Try this:
Modify the gradle-wrapper.properties
distributionUrl=http\://services.gradle.org/distributions/gradle-1.11-all.zip
and your build.gradle
compileSdkVersion 19
buildToolsVersion "19.0.1"
running:./gradlew clean assemble in the terminal

I finally solved it, by removing .idea folder and all .iml files and imported project as new one.
