Program type already present: android.support.v4.media.MediaBrowserCompat$CustomActionCallback

Question

I completely new to Android Development and can\'t seem to resolve this error: \"Error: Program type already present: android.support.v4.media.MediaBrowserCompat$Custom

Answer 1

At least for me the issue was with the implementation 'androidx.legacy:legacy-support-v4:1.0.0-alpha1' dependency. I went into the menu in Android Studio to create a Blank Fragment in Kotlin just to see what that would look like and the dependency above was added.

Once i removed that dependency the error went away.

Answer 2

Some of your existing dependencies are using older versions of support library, try this

implementation 'androidx.legacy:legacy-support-v4:1.0.0-alpha1' {  
exclude group: 'com.android.support'  
exclude module: 'support-v4'
}

Answer 3

Option 1

Following worked for me Add the following in your gradle.properties file

android.useAndroidX = true
android.enableJetifier = false

Option 2 (if above does't work)

1. Android studio -> Navigate -> Class
2. Check include non-project classes
3. Copy full class path android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat
4. See where it is used. You may need to remove, one of them.

Option 3 you might be including package which is including modules as well so exclude the support-v4 module with following method

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

You can analyze the conflicting modules using ./gradlew :YOURPROJECT:dependencies from a command line in your project repository. Check especially your third party libraries for occurences of "com.android.support-":

Then exclude the conflicting modules from these dependencies like:

   implementation ("com.jakewharton:butterknife:8.8.1") {
    exclude group: 'com.android.support', module: 'support-v4'
    exclude group: 'com.android.support', module: 'support-annotation'
    exclude group: 'com.android.support', module: 'support-compat'
}

Answer 4

Im using flutter, and Im adding some native libraries in android, I tried the solutions posted here, but the trick for me was android.enableJetifier = true instead false

So, adding the following code to the gradle.properties, my apps are running:

android.useAndroidX = true
android.enableJetifier = true

Answer 5

if you still getting error after

# gradle.properties
android.useAndroidX = true
android.enableJetifier = false

then you probably forgot about main activity that calling android.support.v7.app.AppCompatActivity change it to androidx.appcompat.app.AppCompatActivity
