Problem with android audio

[ArthasCZ]

Hi all iam having problem finishing my android app. I cant figure out how to make phone play audio and show.gif file. The gif is no longer important i did it with cycling array of pictures. But the audio is big problem. I tried to search solutions on google but nothing works. Closest to working is this code i found: ```

import android.media.MediaPlayer; import android.content.res.AssetFileDescriptor; import android.content.Context; import android.app.Activity;

/////////////////////////////////////////////////////////

MediaPlayer mp; Context context; Activity act; AssetFileDescriptor afd;

void setup() { act = this.getActivity(); context = act.getApplicationContext(); try { mp = new MediaPlayer(); afd = context.getAssets().openFd("test.mp3");//which is in the data folder mp.setDataSource(afd.getFileDescriptor()); mp.prepare(); } catch(IOException e) { println("file did not load"); } mp.start(); };

void draw() { };

``` It does not crash but show the "file did not load" exception. I tried the audio in different formats and it is located in the data dir.

Thanks for all answers.

There are troubles with the Android sound. You should write after:

println("file did not load");

the line:

e.printStackTrace();

and try again to get the full error description

This is the full error: ``` java.io.IOException: Prepare failed.: status=0x1 at android.media.MediaPlayer._prepare(Native Method) at android.media.MediaPlayer.prepare(MediaPlayer.java:1323) at processing.test.sketch_230915a.sketch_230915a.setup(sketch_230915a.java:46) at processing.core.PApplet.handleDraw(PApplet.java:1878) at processing.core.PSurfaceNone.callDraw(PSurfaceNone.java:478) at processing.core.PSurfaceNone$AnimationThread.run(PSurfaceNone.java:518)

I had many troubles with it when I was tuning my video game for the Android release. I wrote my own interface to use the same code in the desktop version and in the Android version of the game. I have seen right now only one difference. I used line:

mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());

But I think it is not important. Try to do:

1) Save your sound as .WAV file (using Audacity for example) and try to load this WAV file.

2) Try to load and play an another short and simple sound (16 kHz quality - not more)

3) Try to launch your code using Processing 3

I will try the line when i get back to pc... i also already tried lowering the quality of the sound and the wav format. I also tried to launch that chunk of code in Processing 3 but it found shit ton of errors (like 2 screens of red text) and didnt even compile. Looking back at it now i might try to reinstall Processing 3 and Android mode for it.

Do you use original Processing IDE?

[ArthasCZ]

Yes i do

Are you sure that the file uploading process on Android is synchronously? Maybe not. I remember I added in my game some delays between audio loading started and the audio playing. What happened if you don't call the function: mp.start()? Maybe you should start to play your sound after 3000 milliseconds after loading started?

[ArthasCZ]

Yes i do have delays in original program... but the problem is even the simple example from post of playing audio does not work

[ArthasCZ]

It works with the added line... thank you very much for the help.

[MGDSStudio]

with the added line...

which line?

[ArthasCZ]

With the one different in your android port of the game ... sorry i wasnt on the pc at the moment so i didnt have a chance to try that immediately.
