Install android for linux

Steps to install Android Development Tool for Linux.

1. Download SDK ADT bundle for linux.
2. Unpack the ZIP file (named adt-bundle-.zip) and save it to an appropriate location, such as a "Documents" directory in your home directory.
3. Open the adt-bundle-/eclipse/ directory and launch eclipse.

That's it! The IDE is already loaded with the Android Developer Tools plugin and the SDK is ready to go. 

Caution: Do not move any of the files or directories from the adt-bundle- directory. If you move the eclipse or sdk directory, ADT will not be able to locate the SDK and you'll need to manually update the ADT preferences.

To proceed with the installation

A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
