Andriod mediaPlayer prepare() failed status=0x1

BigfootSue

I am trying to test the Android's mediaplayer to play sound in a my processing app in Android mode. It keeps failing at prepare. Here is the code.

It fails at player.prepare() and the failure occurs with IOException. I am at a lost. Really appreciate any help.

// libraries
import android.media.MediaPlayer;

// audio variables
MediaPlayer player;

void setup() {

    size (100, 100);

    player = new MediaPlayer();

    try {
        player.setDataSource("wall.wav");
        player.prepare();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    }       

}//setup

void draw () {

}//draw

void mousePressed() {

    if (player.isPlaying()) {//do nothing, is playing
    } else {
        player.seekTo(0); //rewind to beginning
        player.start();
    }

}//mousePressed

void stop() {

    // releases any resource attached with the MediaPlayer object
    player.release();
    super.stop();

}//stop

Hi everyone, I found the solution. I needed to get to the sound file via the android Assets. I found the needed code under a discussion title "Sound Library". Here is the working code. "wall.wav" is just a bell sound located in the data folder.

// libraries
import android.media.*;
import android.content.res.*;

// audio variables
MediaPlayer player;
AssetManager assets;
AssetFileDescriptor fd;

void setup() {

size (100, 100);

player = new MediaPlayer();
assets = this.getAssets();

try {
  fd = assets.openFd("wall.wav");
  player.setDataSource(fd.getFileDescriptor(), fd.getStartOffset(), fd.getLength());
  player.prepare();
} catch (IOException e) {
  e.printStackTrace();
} catch (IllegalArgumentException e) {
  e.printStackTrace();
} catch (IllegalStateException e) {
  e.printStackTrace();
}    

}//setup

void draw () {

}//draw

void mousePressed() {

if (player.isPlaying()) {//do nothing, is playing
} else {
  player.seekTo(0); //rewind to beginning
  player.start();
}

}//mousePressed

void stop() {

// releases any resource attached with the MediaPlayer object
player.release();
super.stop();

}//stop

@marioporty88: Android's MediaPlayer is part of the Android API, so you do not need any additional libraries.
