Problem adding a dependency in Android Studio?

Question

I am getting a problem when I try to add a dependency in Android Studio. I want to add com.android.support:design:28.0.0 to dependencies, but I am getting an error like this:

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
}

ERROR: Manifest merger failed with multiple errors, see logs

Answer 1

You are using both androidx and android support library. Replace android support library with the existing androidx library.

  androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'

You can find their androidx version here
