One of the libraries i am using was containing the google GSON package and when i am trying to run the build , it shows me error of duplicate entry. Then i used a tool called JarSplice to merge both of the libraries into one, and while merging this tool remove the duplicate items and create a standalone Jar file.

I also had the same problem. Adding the following to the buildTypes section fixed it for me.

debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
