There are a number of Android apps that produce music in a MIDI format (from on-screen keyboards etc) and use MIDI over WiFi or Bluetooth. <br />
Look at<a href="http://thesundancekid.net/blog/fingerplay-midi/" rel="ugc"> Fingerplay</a> or <a href="https://market.android.com/details?id=souvey.musical.pro&hl=en" rel="ugc">Musical Pro</a> as &nbsp;examples. <br />
The big problem with MIDI has been the lack of support for the javax.sound.midi class on Android.<br />

Maybe I need to refine my question as following.<br />
<br />
How can I make a sound on my Android 4 phone (e.g. Galaxy Nexus) by specifying instrument, note, duration, etc. ? Which class I can make it happen ? (I do not want to use the JetPlayer)<br />
<br />
Cheers.

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).
