Application Fundamentals Android apps are written in the Java programming language. The Android SDK tools compile your code—along with any data and resource files—into an APK: an Android package, which is an archive file with an .apk suffix. One APK file contains all the contents of an Android app and is the file that Android-powered devices use to install the app. Once installed on a device, each Android app lives in its own security sandbox: The Android operating system is a multi-user Linux system in which each app is a different user. In this way, the Android system implements the principle of least privilege. However, there are ways for an app to share data with other apps and for an app to access system services: It's possible to arrange for two apps to share the same Linux user ID, in which case they are able to access each other's files. That covers the basics regarding how an Android app exists within the system. The core framework components that define your app. App Components Activities Services <?
Multitasking the Android Way [This post is by Dianne Hackborn, a Software Engineer who sits very near the exact center of everything Android. — Tim Bray] Android is fairly unique in the ways it allows multiple applications to run at the same time. Developers coming from a different platform may find the way it operates surprising. Understanding its behavior is important for designing applications that will work well and integrate seamlessly with the rest of the Android platform. Design considerations Mobile devices have technical limitations and user experience requirements not present in desktop or web systems. We did not want to require that users close applications when "done" with them. The first two requirements highlight an interesting conflict. When does an application "stop"? A common misunderstanding about Android multitasking is the difference between a process and an application. The fact that you can see an application's process "running" does not mean the application is running or doing anything.
