Extracted from here :

Android 1.6 and higher SDK platforms include a new application
pre-installed on the emulator, called Gestures Builder. You can use
this application to create a set of pre-defined gestures for your own
application…

…

As you can see, a gesture is always associated with a name. That name
is very important because it identifies each gesture within your
application. The names do not have to be unique. Actually it can be
very useful to have several gestures with the same name to increase
the precision of the recognition. Every time you add or edit a gesture
in the Gestures Builder, a file is generated on the emulator’s SD
card, /sdcard/gestures. This file contains the description of all the
gestures, and you will need to package it inside your application
inside the resources directory, in /res/raw.

Here you have the source code of Gesture Builder

Gesture builder is installed in the emulator , but you can download it from here
