play-services-ads conflicts with appcompat

Question

When I add implementation \'com.google.android.gms:play-services-ads:18.2.0\' to my build.gradle, Android Studio highlights implementation \'com.android.s

Answer 1

You are using

implementation 'com.google.android.gms:play-services-ads:18.2.0'

Google Play services migrated to AndroidX in the latest release.

Dependencies using groupId com.android.support and androidx.* can not be combined

It means that you are using both, support libraries and androidx libraries.

You can:

• migrate to androidx as described below (in your case you have to migrate appcompat to implementation 'androidx.appcompat:appcompat:1.0.2')
• downgrade your google play ads dependencies (but it is not a real solution because you have to migrate sooner or later)

You can check the official release notes:

Warning: This release is a MAJOR version update and breaking change. The latest update to Google Play services and Firebase includes the following changes:

Migration from Android Support Libraries to Jetpack (AndroidX) Libraries. Libraries will not work unless you make the following changes in your app:

• Upgrade com.android.tools.build:gradle to v3.2.1 or later.
• Upgrade compileSdkVersion to 28 or later.
• Update your app to use Jetpack (AndroidX); follow the instructions in Migrating to AndroidX.
