The package name of an Android app uniquely identifies your app on the device, in Google Play Store, and in supported third-party Android stores.
Google Play Store
You can find an app's package name in the URL of your app’s Google Play Store listing. For example, the URL of an app page is play.google.com/store/apps/details?id=com.example.app123. The app's package name is com.example.app123.
When you set up an app in AdMob, your AdMob app will use the same package name as your Google Play app if you link the app to the Play Store. If your app shares the same package name in other third-party stores, make sure you also select those stores when setting up your app in AdMob. If you use a different package name for the app on other Android stores, we recommend you create a separate AdMob app for each.
Other supported Android stores
At this time, AdMob supports the Amazon Appstore, OPPO App Market, Samsung Galaxy Store, VIVO App Store, and Xiaomi GetApps.
For these stores, the package name can be found in the AndroidManifest.xml file of the Android app APK. Note that for some stores such as Amazon, the app ID is not the same as the package name.
For additional help finding your app’s package name, refer to your third-party app store’s documentation. Note that package names and format can vary between stores.
