// paste this properties in gradle.properties

android.useAndroidX=true

android.enableJetifier=true

  1. First Property will use appropriate androidx libraries instead of using old support libraries.

  2. Second will migrate all third party libraries to androidx libraries.

You need to upgrade the version, you can do this by using the sequence Alt+Enter over the line:

enter image description here

Nowadays you don´t need to use all Google Play Services, just modules, examples:

implementation 'com.google.android.gms:play-services-ads:VERSION'
implementation 'com.google.android.gms:play-services-auth:VERSION'
implementation 'com.google.android.gms:play-services-gcm:VERSION'

but if you really need to use 'com.google.android.gms:play-services:VERSION', to avoid duplicated classes uses this configuration inside your app/build.gradle file:

implementation ('com.google.android.gms:play-services:10.2.4') {
    exclude group: "com.android.support", module: "support-v4"
}
