Unable to merge dex

Question

I have Android Studio Beta. I created a new project with compile my old modules but when I tried launching the app it did not launch with the message:

Error:         


        

Answer 1

Installing Google play services (latest version) + including

android {
    defaultConfig {
        multiDexEnabled true
        }
}

in build.gradle solved the issue for me, make sure to clean and rebuild project!
