Answer 1

I had the same problem after SDK update. In my case the solution was to remove 24.0.0-alpha1 folder from sdk/extras/android/m2repository/com/android/support/appcompat-v7 and to delete <version>24.0.0-alpha1</version> line from sdk/extras/android/m2repository/com/android/support/appcompat-v7/maven-metadata.xml

Answer 2

This worked for me.

In build.gradle of Project (not module) i changed the classpath.

It now looks like this

dependencies {
    classpath 'com.android.tools.build:gradle:1.3.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

Hope it helps someone.
