Android SDK

[2][3] These include a debugger, libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials.

The SDK is part of the official Android Studio IDE but its various tools and resources can be used independently.

Additionally, developers may use any text editor to edit Java and XML files, then use command line tools (Java Development Kit and Apache Ant are required) to create, build and debug Android applications as well as control attached Android devices (e.g., triggering a reboot, installing software package(s) remotely).

[11] Android applications are packaged in .apk format and stored under /data/app folder on the Android OS (the folder is accessible only to the root user for security reasons).

The Android SDK Platform Tools are a separately downloadable subset of the full SDK, consisting of command-line tools such as Android Debug Bridge and fastboot.
