D8：程序类型已经存在：android.support.v4.media.MediaBrowserCompat$CustomActionCallback

Question

I am new to flutter and i build a very little app showing current latitude and longitude which required me to add two dependencies in pubspec.yaml :-

location and simple_permissions to get current user location and asking for location permission.

but when i ran the app it shows following error:-

Gradle task 'assembleDebug'...
D8: Program type already present: android.support.v4.media.MediaBrowserCompat$CustomActionCallback

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

BUILD FAILED in 9s
Finished with error: Gradle task assembleDebug failed with exit code 1

i think it is because of adding a library two times but i am not adding dependencies manually so it is flutter error inside.

Please tell me solution of it

Answer 1

This gradle error messages are so hard to solve... Well I had some problems like this and I wrote how I solved here . Anyway I advise you to use updated packages in your pubspec. simple_permissions package has been a while there is no updates, try permission_handler package instead. Other point to avoid future build problems is migrate your app to androidX and use dependencies which already using androidX too, a lot of official plugins are migrating to it and when we mix support library with androidX in the same project the build process fails sadly. If you are planning include google_maps in you app I really recommend you migrate to androidX instead avoid it.

AndroidX is the original support library packages and classes with other namespace. Full description here .

You can migrate to androidx manually or you can use android-studio migration tool that some times fails. A migration process with android-studio tools has been already described here in details.

To migrate manually you need replace all your support library dependencies by respective androidx package. An example is:

dependencies {
   // using support library
   implementation 'com.android.support:appcompat-v7:$version' 
}

Must be replaced by

dependencies {
       // using androidx
       implementation 'androidx.appcompat:appcompat:$version' //androidx artifact 
    }

Androidx artifact mappings can be found here In your gradle.properties file you need insert this two lines below

android.enableJetifier=true
android.useAndroidX=true

And make sure your flutter dependencies are using androix too.

Take a look at this flutter page it talks about androidX compatibility and migration.

I hope it helps.

Answer 2

I had same problem

added this in gradle.properties

android.enableJetifier=true 
android.useAndroidX=true

In build.gradle (app level) Removed : implementation 'com.android.support:support-v4:27.1.1'

added :

implementation `"androidx.legacy:legacy-support-v4:1.+"`

and Run Clean and Invalidate Cache & Restart - worked out

Answer 3

Using Ionic, solved by adding following plugins

cordova plugin add cordova-plugin-androidx
cordova plugin add cordova-plugin-androidx-adapter

Regards!

Answer 4

对我来说是插件cordova-plugin-mfilechooser，它已经没有使用androidx（使用Phonegap）
