Android Apps are written in Java. The Android SDK tools compile the code, data and resource files into an APK (Android package). Generally, one APK file contains all the content of the app.

Each app runs on its own virtual machine(VM) so that app can run isolated from other apps. Android system works with the principle of least privilege. Each app only has access to the components which it requires to do its work, and no more. However, there are ways for an app to share data with other apps, such as by sharing Linux user id between app, or apps can request permission to access device data like SD card, contacts etc.
