Adding Music to Android Using Processing.

Spicee

Hi there,

I'm making a game for my phone but I'm having trouble adding music. I tried using minim but it doesn't work for android. Instead I've used processing sound and while the sound plays find when I run it on my computer, when I try to run in on my phone I get this error message.

FATAL EXCEPTION: Animation Thread

I don't know what this means. Maybe some one else can help?

My code:

@Spicee=== from the error message i guess that there is a problem with a library which cannot be found or loaded; are you sure that your sound lib is compatible with android??? - And why not using the "standard" android mediaPlayer component which runs fine for playing sound files???

Spicee

@akenaton To be honest I have no idea how to do that. Do you think you could show me how to get a wav file to play on android?

koogs

try moving size() to the top of setup() (line 36)

you are trying to load a file and it's possible that the default path hasn't been set up yet (because you're calling it before size())

(we can't run your code because we lack the sound and image files, so the above is largely a guess)

Spicee

@koogs It's really hard to find a guide for importing music in android mode. I'll try what you suggested, thanks.!

akenaton

@Spicee: have you verified wethher the sound library can be used with android??? - that is the first thing to do. As for media player see my code (in some cases you have to add mediaPlayer.prepare() in the init method. see the android doc.

        import apwidgets.*;


        PMediaPlayer player;
        boolean play = false;



        void setup() {

        orientation (PORTRAIT);

        initPlayer();

        }
        void draw() {
        background(0);


        }


        public void onPause(){
          super.onPause();
          if(play){
            player.pause();

            play = false;
          }
          }

          public void onResume() {
            super.onResume();  


            if (play == false) {
              initPlayer();


            }
        }

    private void initPlayer(){
       player = new PMediaPlayer(this); //create new APMediaPlayer   
      player.setMediaFile("your.mp3");
      //player.setLooping(true); 
      player.setVolume(1.0, 1.0);
            player.start(); 
            play = true;
    }



    public void onDestroy() {
    super.onDestroy(); 
     if (player!=null) { //must be checked because or else crash when return from landscape mode
     player.release(); //release the player
     }
    }

@Spicee:: of course you have to find & load the lib apwidgets!!...
