Android Studio - Error:Program type already present

Add this to your module build.gradle file

  configurations.all {exclude group: 'com.android.support', module: 'support-v13'}

I just had the same problem so I will share the solution that worked for me. My error was:

Program type already present: org.json.CDL

and it started appearing after I added compile acra to my gradle file. So the solution was to add acra like this:

    compile('ch.acra:acra:4.5.0') {
    exclude group: 'org.json'
}   

So in OP's case the solution would be to find which one of his dependencies already compiles com.squareup.picasso and exclude like in the code above.
