Google does not pay for app downloads on the Google Play Store. Instead, developers can monetize their apps through a variety of methods, including in-app purchases, subscription models, and advertising. The amount of money a developer can earn through these methods will depend on a variety of factors, including the popularity of the app, the quality of the app, and the monetization strategy employed.
It’s worth noting that getting 1000 downloads on the Google Play Store is just one step in the process of monetizing an app. Once an app has been downloaded, the developer will need to focus on engaging users and encouraging them to make in-app purchases or use paid features in order to generate revenue.
