Android Studio - Error:Program Type Already Present

What does Program type already present mean?

This problem usually come from a naming conflict, in your case the support-v4 library, which is use by several libraries.

To find the list of dependencies for the module app (default module's name for the app) we can do a gradlew app:dependencies to retrieve a list of all the libraries.

We found that support-v4 is used by:

//short version of the dependencies list highlighting support-v4
+--- com.android.support:support-v13:27.1.0
|    \--- com.android.support:support-v4:27.1.0

+--- com.google.android.gms:play-services-maps:12.0.1
|    +--- com.google.android.gms:play-services-base:12.0.1
|    |    +--- com.google.android.gms:play-services-basement:12.0.1
|    |    |    +--- com.android.support:support-v4:26.1.0 -> 27.1.0 (*)

+--- org.eclipse.paho:org.eclipse.paho.android.service:1.0.2
|    +--- com.google.android:support-v4:r7  // <- problem here

We see that the support-v4 on Maps will use the version provided from support-v13.

We also see that the eclipse library is using another version (r7 ??).

To resolve your issue, you can try to exclude the module support-v4 from this eclipse library like this:

implementation ('org.eclipse.paho:org.eclipse.paho.android.service:1.0.2') {
    exclude module: 'support-v4'
}

Then you should be able to compile your application.

Btw you should take care that the eclipse module won't break by testing your code.

Getting Program type already present error in Android Studio

After 2 days of RND, finally I got the answer. Adding below code in my app-level build.gradle file worked for me--

android {
    dexOptions {
        preDexLibraries = false
    }
} 

For more details, please check the answer given by "iceman" on this post.

What is Program type already present?

 implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'

downgrade the version of dependency to

 implementation 'com.android.support:appcompat-v7:27.1.0'

and also add the design dependency

 implementation 'com.android.support:design:27.1.0'

check it once this works for me

AGPBI: {kind:error,text:Program type already present:

Starting from version 18.0.0 dependency com.google.android.gms:play-services-ads uses AndroidX packages instead of Support Library. This dependency adds androidx libraries to your project transitively, you can check it using "gradlew app:dependencies" task:

+--- com.google.android.gms:play-services-ads:18.0.0
|    +--- androidx.collection:collection:1.0.0
|    |    \--- androidx.annotation:annotation:1.0.0
|    +--- androidx.core:core:1.0.0
|    |    +--- androidx.annotation:annotation:1.0.0
|    |    +--- androidx.collection:collection:1.0.0 (*)
|    |    +--- androidx.lifecycle:lifecycle-runtime:2.0.0
|    |    |    +--- androidx.lifecycle:lifecycle-common:2.0.0
|    |    |    |    \--- androidx.annotation:annotation:1.0.0
|    |    |    +--- androidx.arch.core:core-common:2.0.0
|    |    |    |    \--- androidx.annotation:annotation:1.0.0
|    |    |    \--- androidx.annotation:annotation:1.0.0
|    |    \--- androidx.versionedparcelable:versionedparcelable:1.0.0
...

Each androidX dependency contains both android and androidx packages. Since gradle sees two different dependencies with the same packages inside, it has no other choice but to throw an error.
As a solution, you can downgrade your 'com.google.android.gms:play-services-ads' to version 17.2.1, since it's the last version that uses old support packages. Other solution might be migrating your project to AndroidX

Android program type already present error

one of these lines might define ff.ecochallenges.game twice:

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation project(":garden-release")
implementation project(":game")

would assume, that there either is a .jar contained in the libs directory

or module garden-release might have a dependency on module game.

eg. you could use api project(":game") in module garden-release.

Program type already present: BuildConfig

You are getting this error because you a have library module which has the same package name as the app module.

The solution would be to change package name of your library module. You can follow the accepted answer in this SO which describes how to change the package name in android studio.

Error: Program type already present: androidx.core.R

You have a problem with the order of plugins applied.

apply plugin: 'com.google.gms.google-services' This should always be kept at the end of file.

Also, apply plugin: "io.fabric" should be applied after com.android.application.

If you still have confusions on build.gradle. Edit your question including both buid.gradle files from app and root project, and inform me by commenting on this answer.

    apply plugin: 'com.android.application'
    apply plugin: "io.fabric"

    apply plugin: "kotlin-android-extensions"
