hello

after quite a bit of messing around i finally managed to get pd-for-android working yay!
but now i have no idea where to start. im new to pd but not to programming.
ive had a look at the demo's that come with it and dont really know what im looking at.
i can see messages are sent and functions are called from the android java to the pd patch but after that is completely bewildering.

are there any examples or tutorials that show the very basics of whats going on?
for instance, press a button in android and play a sample, or a slider to change pitch of an oscilator.

also is there a code reference for pd?
would be quite handy.

thanks

have fun!

thanks Gromit, some good links there.

so to be sure i understand this, taking PdTest as an example,

in the patch there is an object with 'r left' in it that basically turns the left osc on and off.

in the android bit there is this

PdBase.sendFloat("left", left.isChecked() ? 1 : 0);

and that sends a float of either 0 or 1 depending if the checkbox is checked.

so i follow that basic pattern for any messages i want to send to the patch?

edit;
so i just tried adding a float to change the pitch with a seekbar
and i get
could not find PdCore.apk
any ideas?

Hey tegleg,

You might get some more specific answers regarding libpd on the noisepages forum - http://noisepages.com/groups-2/pd-everywhere/

Peter Brinkmann, the main guy behind libpd, is on there.

Cheers,
Joe

ah thats where that forum has gone, thanks
all the links i found before point to an empty page.

Yeah I think they've updated it recently and broke all the links

NoisePages is pretty hard to use: when I tried to create a new account, it served up a page not found error, and must have failed as I could not log in. If only Peter Brinkmann used these forums instead.

As to using pd on Android, be sure to check out the opensl branch. I originally tried the default branch, and was about to give up: extremely crackly and broken up sound. The opensl implementation, on the same device works a treat.

To get the opensl distribution use:

$ git clone -b opensl git://github.com/libpd/pd-for-android.git
$ cd pd-for-android
$ git submodule init
$ git submodule update

In essence it's the first command that specifies the different branch to use.

wehay it works again
thanks ThisIsNotMe

nowhere have i seen that branch mentioned.
maybe there could be a sub-forum on here for android developent?

Yeah NoisePages looks very funny for me atm, a lot of text is cut-off randomly.

oooh nooooo lol
i restarted eclipse and i get pdcore.apk error again.
so what could be causing this? or what will fix it more like?

edit:
what will fix it is project properties - android
remove pdcore library, apply
add pdcore, apply

i still get the error but at least the app opens

The open sl branch is mentioned in Peter Brinkmann's blog

I suspect it will be part of the main branch once the code is stable.

As to your Eclipse problem, not sure what could be causing that. I do have the other PdCore project in Eclipse, but closed the project. I created a new project called PdCoreOpenSl in Eclipse, and reference that one.

a few days of testing and ive narrowed down the problem area.
when i add PdCore to a new project it crashes when i try to set up the receiver.
all im doing is adding the code from PdTest and seeing whats what.
the app runs fine as long as i dont include the code below

private PdReceiver receiver = new PdReceiver() {

public void receiveBang(String source) {
// TODO Auto-generated method stub

}

public void receiveFloat(String source, float x) {
// TODO Auto-generated method stub

}

public void receiveSymbol(String source, String symbol) {
// TODO Auto-generated method stub

}

public void receiveList(String source, Object... args) {
// TODO Auto-generated method stub

}

public void receiveMessage(String source, String symbol, Object... args) {
// TODO Auto-generated method stub

}

public void print(String s) {
// TODO Auto-generated method stub

}

};
