APMediaPlayer doesn't seem to work with Android. I'm following a standard procedure but every time it returns the error:

FATAL EXCEPTION: Animation Thread

java.lang.NullPointerException

at processing.test.screenpad2.screenpad2.setup(screenpad2.java:34)

at processing.core.PApplet.handleDraw(Unknown Source)

at processing.core.PGraphicsAndroid2D.requestDraw(Unknown Source)

at processing.core.PApplet.run(Unknown Source)

at java.lang.Thread.run(Thread.java:856)

The same error message came when we tried Minim library as well. Kindly suggest possible solution. We are in dire need.

Csoundo works for Android, if your prepared to learn how to write a bit of Csound code you can do just about anything in terms of audio. Get in contact if your setting it up. https://github.com/rorywalsh/Csoundo
