I am using admob and facebook for ads in my app and its done but I want to check it so i have added Mediation Test Suite depnedancy
implementation 'com.google.android.ads:mediation-test-suite:2.0.0'
And the app could not build it shows
Duplicate class com.google.android.flexbox.AlignContent found in modules jetified-flexbox-1.1.1-runtime (com.google.android:flexbox:1.1.1) and jetified-flexbox-3.0.0-runtime (com.google.android.flexbox:flexbox:3.0.0)
Duplicate class com.google.android.flexbox.AlignItems found in modules jetified-flexbox-1.1.1-runtime (com.google.android:flexbox:1.1.1) and jetified-flexbox-3.0.0-runtime (com.google.android.flexbox:flexbox:3.0.0)
And many more Duplicate Class of Flexbox
my admob version
implementation 'com.google.android.gms:play-services-ads:20.4.0'
The package name is wrong.
com.google.android:flexbox:1.1.1
Here is the correct one. ↓
implementation ('com.google.android.ads:mediation-test-suite:2.0.0') {
exclude group: "com.google.android", module: "flexbox"
}
It worked for me.
