As of 2015, Android Studio is the official IDE however, developers are free to use others, but Google made it clear that ADT was officially deprecated since the end of 2015 to focus on Android Studio as the official Android IDE.

Until around the end of 2014, the officially-supported integrated development environment (IDE) was Eclipse using the Android Development Tools (ADT) Plugin. As of March 2015, the SDK is not available on Android itself, but software development is possible by using specialized Android applications. Currently supported development platforms include computers running Linux (any modern desktop Linux distribution), Mac OS X 10.5.8 or later, and Windows 7 or later. These include a debugger, libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials.


The Android SDK is a software development kit that includes a comprehensive set of development tools.
