Installing Android platform tools (ADB) on Ubuntu and Debian systems

Here is a short script I use to install the latest version of Android platform tools on those of my systems I do not need full blown Android SDK on:

The script requires root permissions to install prerequisite packages. It downloads and unpacks adb and fastboot binaries into $ANDROID_SDK_HOME/platform-tools/ folder (or into ~/android/platform-tools/ if $ANDROID_SDK_HOME is not defined). The folder will be added to the current $PATH. And finally the script will create a universal udev rule to take care of device permissions for all Android devices regardless of their VendorID.

The script has been tested on 32 and 64-bit versions of Ubuntu 12.04, 12.10, 13.04, 13.10 and Debian 7.0, 7.1, 7.2.

Universal udev rule for all Android devices

When an Android device is plugged in to a linux system, by default only root has access to the device. In order for regular users to be able to access the device - the device permissions need to be changed. To automate this, Google recommends  adding Vendor ID of every Android device as a separate line per ID.
I thought that there has to be a better way to do it. Here is the rule I came up with:

ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="*:ff420?:*", MODE="0666"

This rule matches all adb and fastboot interfaces for any android device, no matter the Vendor ID.
