Android mobile apps are software applications designed to run on devices that use the Android operating system, such as smartphones, tablets, and smart TVs. These apps can be downloaded from the Google Play Store or other app marketplaces and installed on Android devices.

Android apps can be created using various programming languages such as Java, Kotlin, and C++. Developers can use Android software development kits (SDKs) and integrated development environments (IDEs) such as Android Studio to create and test their apps.

There are a wide variety of Android apps available, ranging from games and social media platforms to productivity and utility apps. Some popular examples of Android apps include WhatsApp, Facebook, Instagram, YouTube, Google Maps, and Gmail.

Android apps are typically developed to be compatible with multiple Android devices, allowing them to reach a larger user base. They can also be updated and improved over time, with new features and bug fixes released through app updates.
