Alongside Android 4.1, Google also began to decouple APIs for its services on Android into a new system-level component known as Google Play Services , serviced through Google Play Store . This allows the addition of certain forms of functionality without having to distribute an upgrade to

In the summer of 2019, Huawei announced it would create an alternative operating system to Android known as Harmony OS , and has filed for intellectual property rights across major global markets. Under such sanctions Huawei has long-term plans to replace Android in 2022 with

4450-489: The Storage Access Framework (SAF), a set of APIs for accessing files on the device's filesystem. As of Android 11, Android has required apps to conform to a data privacy policy known as scoped storage , under which apps may only automatically have access to certain directories (such as those for pictures, music, and video), and app-specific directories they have created themselves. Apps are required to use

The company then decided that the market for cameras was not large enough for its goals, and five months later it had diverted its efforts and was pitching Android as a handset operating system that would rival Symbian and Microsoft Windows Mobile . Rubin had difficulty attracting investors early on, and Android
4984-555: The cost of the application is added to the user's monthly bill. As of May 2017 , there are over one billion active users a month for Gmail, Android, Chrome, Google Play and Maps. Due to the open nature of Android, a number of third-party application marketplaces also exist for Android, either to provide a substitute for devices that are not allowed to ship with Google Play Store, provide applications that cannot be offered on Google Play Store due to policy violations, or for other reasons. Examples of these third-party stores have included
