Android Studio - Error:Program type already present

Question

When I try to compile the code, the following error appears on Android Studio 3.0.1

Error:Program type already present: com.squareup.picasso.Action$RequestWeakReference

My gradle code:

  ...
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:design:26.1.0'
    compile 'com.android.support:support-v4:26.1.0'
    compile 'com.android.support:support-vector-drawable:26.1.0'
    compile 'com.android.support.constraint:constraint-layout:1.1.0-beta4'
    compile 'com.google.firebase:firebase-messaging:11.8.0'
    compile 'com.google.firebase:firebase-ads:11.8.0'
    compile 'com.google.gms:google-services:3.1.0'
    compile 'com.google.android.gms:play-services:11.8.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    testCompile 'junit:junit:4.12'

}

apply plugin: 'com.google.gms.google-services'

How do I fix my gradle script to fix the error?

Answer 1

Add this to your module build.gradle file

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

Answer 2

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.

Answer 3

Check the compile version in your App settings. I changed it to the version compatible with the API level I've built my project with. This fixed the problem for me.

Answer 4

I faced nightmare of multiple troubles building APK after I upgraded Android Studio to 3.1.2 and targetSdkVersion to 27. This was one of them.

implementation 'me.leolin:ShortcutBadger:1.1.21@aar' 

This line causing build error Program type already present: me.leolin.shortcutbadger.Badger

For now I just commented it out and it compiled smoothly.
