libpd on Android using Windows as Dev Platoform?

in Android Processing • 5 months ago

Hi,

I am working on a space, trance inducing, game for android (well actually want it to work in most platforms), and I need to add generative sound to it.

I am wondering if there is a way to get libpd + Processing working in Android using Windows as development platform?

After searching for two days I could not find the answer, as there were some posts (somewhere else) sort of implying that they were able to generate the windows binaries somehow.

Now if this is not possible under Windows, does anyone know if there is any project to get it working?

Or what other options do I have to get generative audio in Android?

Yes it's possible, but for now you can't do it in processing's IDE.

You'll have to use something like eclipse. So you need :

1- to install eclipse

2- to install drivers for you phone(some need drivers), and the ADT (Android Developpement Tools) plugin for eclipse

3- download libpd from github

4- import PdCore in eclipse, make sure it is handled as a library (properties -> Android -> isLibrary must be ticked) clean & build to get rid of errors.

5- import PdTest and try to compile it on your phone.

6- write the beginning of a sketch in processin IDE, save it and export it to an android application

7- import this in eclipse as new android project

8- link to pdCore : properties -> Android -> Add... select pdCore

then it's done :)

you need to import your lib in your app :

import org.puredata.android.io.AudioParameters;
import org.puredata.android.io.PdAudio;
import org.puredata.android.service.PdPreferences;
import org.puredata.android.service.PdService;
import org.puredata.android.utils.PdUiDispatcher;
import org.puredata.core.PdBase;
import org.puredata.core.PdListener;
import org.puredata.core.PdReceiver;
import org.puredata.core.utils.IoUtils;

Here is tome code to get started setting up libpd :

private static final String TAG = "myapp";
private PdUiDispatcher dispatcher;
private PdService pdService = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try{
initPd();
loadPatch();
}catch (IOException e){
//Log.e(TAG,e.toString());
finish();
}
}
// we specify a dispatcher in this method to receive messages from pd
public void initPd() throws IOException{
// conf audio glue
int sampleRate = AudioParameters.suggestSampleRate();
PdAudio.initAudio(sampleRate, 0, 2, 8, true);
// create and install dispatcher to receive messages from pd
dispatcher = new PdUiDispatcher();
PdBase.setReceiver(dispatcher);
dispatcher.addListener("step_draw", new PdListener.Adapter(){
@Override
public void receiveFloat(String source, final float x){
//Log.i(TAG,"step_draw : "+x);
beat =x; // put what we receive in a variable
}
});
}
private void loadPatch() throws IOException {
File dir = getFilesDir();
IoUtils.extractZipResource(getResources().openRawResource(R.raw.patch),dir,true); // fetch patch.zip
File patchFile = new File(dir,"_main.pd"); // extract and fetch _main.pd
PdBase.openPatch(patchFile.getAbsolutePath());
}
protected void onResume(){
super.onResume();
PdAudio.startAudio(this);
}
protected void onPause(){
super.onPause();
PdAudio.stopAudio();
}
public void onDestroy(){
super.onDestroy();
PdAudio.release();
PdBase.release();
}

Now you can send a message from processing to pd like this :

PdBase.sendFloat("myPdReceiver", myVariableToSend);

From pd to processing, you need to use a dispatcher, see the code above in the initPd() function.

Maybe there are some better ways of doing this, and there should be easier ways as soon as the Pure Data lib for processing will be up and running. But or now, that's it and it works for me

Excellent Beregerr!!! Thank you very much for a most informative post.

I have another question: since it is much more efficient to code and test on the PC, I am wondering if it is possible to get Processing + PD working under Windows as well?

At this point my game at an advanced alpha stage, and it was built in Windows entirely, with frequent testing in android mode. This workflow is very efficient and I would hate having to wait for the device (currently a Nexus 7) every time I need to run the code.

Any ideas?

P.S. Is there any info or timeline for the aforementioned Pure Data lib for Processing?
