Your project has set `android.useAndroidX=true` but configuration `debugRuntimeClasspath` still contains legacy support libraries

Question

I am getting an warning in android studio when I run my app. the warning is- Your project has set android.useAndroidX=true, but configuration debugRuntimeClasspath still contains legacy support libraries, which may cause runtime issues. And a error- Manifest merger failed with multiple errors, see logs I checked my manifest file and there is no error in my manifest file. I tried debugging the app but it still doesn't fix. I am getting this after updating android studio from android studio arctic fox to android studio bumble bee which is recently released. I updated the gradle version tried cleaning project, invalidating caches but nothing worked. I increased the memory heap size and enabled multidex but still it is not fixed. Please help me out.

Please review your project dependencies if they contain legacy libraries – Alexaalexander

Answer 1

1. Comment this line in settings.gradle

repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)

2. Add this in build.gradle (project level):

allprojects {
   repositories {
       google()
       jcenter()
       maven { url "https://jitpack.io" }
   }
}

3. Add in gradle.properties:

android.enableJetifier=true
android.useAndroidX=true

Dmz

still not working have any other solution?? – Deem

For me, It worked with the line "android.enableJetifier=true" and by setting maven { url "jitpack.io" } in settings.gradle file. – Kristlekristo

jcenter() is shot down since February 1, 2022 and can no longer be used. – Exterminatory

Why do we need Jitpack.io here? – Lanam

I did same things without using maven { url "https://jitpack.io" } and it solved my problem – Loop

Answer 2

Add these in gradle.properties:

android.enableJetifier=true
android.useAndroidX=true

Sync your gradle and Run the app. It worked fine for me and I didn't have to do the changes in setting.gradle and build.gradle (Project level) or any other files.

This worked fine and No needed to change anywhere else. – Pincers

Answer 3

My solution is simialar to @JJ Smith one. But I didn't do anything to build.gradle file. So:

1. Comment this line in setting.gradle:

repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)

2. Make sure you have these 2 lines in gradle.properties (if not add them or change them to true):

android.enableJetifier=true
android.useAndroidX=true

3. Sync gradle

I DID NOT change the build.gradle(at project level) file. I report it here just for the sake of completeness:

buildscript {
    repositories {
        google()
    }
    dependencies {
        //...
    }
}


plugins {
    id 'com.android.application' version '7.2.0' apply false
    id 'com.android.library' version '7.2.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.21' apply false
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Operable

Answer 4

Check if you the following dependency:

implementation 'com.android.support:multidex:1.0.3'

If you have it, just remove it. It worked for me.
