Processing + Android

Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.

• Free to download and open source
• Interactive programs using 2D, 3D or PDF output
• OpenGL integration for accelerated 3D
• For GNU/Linux, Mac OS X, and Windows
• Projects run online or as double-clickable applications
• Over 100 libraries extend the software into sound, video, computer vision, and more...
• Well documented, with many books available

Processing for Android project is aim to make it foolishly easy to create Android apps using the Processing API. Once you have Processing on your machine (and the Android developer tools), you can simply write a line of code, hit Run (Ctrl-R or Cmd-R), and have your sketch show up in the emulator as a working Android app. Select Run on Device (Ctrl-Shift-R or Cmd-Shift-R) to have it run on an Android device that you have plugged into your machine. That's good stuff!

Release MediaPlayer in onDestroy() and onPause()

If you try run the last exercise of "Simple example of using MediaPlayer", you can notice that if you exit the app, the sound will still playing, and then switch back to the app, both old sound and new sound will overlap.

Actually, you have to release the MediaPlayer in onDestroy() and onPause(), when the app exit. Or any other handling method, depends on your own case.

 @Override
 protected void onDestroy() {
  // TODO Auto-generated method stub
  super.onDestroy();
  if (mediaPlayer != null) {
   mediaPlayer.release();
   mediaPlayer = null; 
  }
 }

 @Override
 protected void onPause() {
  // TODO Auto-generated method stub
  super.onPause();
  if (mediaPlayer != null) {
   mediaPlayer.release();
   mediaPlayer = null; 
  }
 }
