- <![CDATA[
-The Android MIDI API ([android.media.midi][1]) allows developers to connect a MIDI device to Android
-and process MIDI signals coming from it. This sample demonstrates some basic features of the MIDI
-API, such as enumeration of currently available devices (Information includes name, vendor,
-capabilities, etc), notification when MIDI devices are plugged in or unplugged, and receiving MIDI
-signals. This sample simply shows all the received MIDI signals to the screen log and does not play
-any sound for them.
