My first Android development experiment, so don't expect anything nice here. It needs some work to be fully a proper Android app.

Essentially, this is a little instrument tuner and little game to practice your scales, including feedback.

With ANDROID_HOME set to the location of the sdk and JAVA_HOME set to the jdk, connect your debug enabled phone and type:

ant debug && ant installd

These are the two interesting activities

A Tuner

.. and a scale practice activity showing a histogram of how far off you are for certain notes and gives you a final score.
