Hello Aderalxnu,
The imported folder should just be the folder mopub-sdk and not mopub-android-sdk/mopub-sdk. The mopub-sdk folder should be in the same directory level as your app’s folder.
In Android Studio navigate to your project’s settings.gradle file and include the MoPub SDK as a module as shown below. You may need to sync Gradle again in Android Studio to have the ‘mopub-sdk’ show up in the left Project window.
include ':app', ':mopub-sdk'
Open your app’s build.gradle file and add the MoPub SDK as a dependency:
dependencies {
compile project(':mopub-sdk')
}
Let me know if this fixes your issue. If not, we can troubleshoot further.
Thanks!
