Ok, I've actually managed to get this working after a Sunday of hacking (thanks again to the tremendous work by Peter Brinkmann). Here is the code if you want to check it out:
http://gitorious.org/~chr15m/pd-for-android/aurioid-pd-webkit
If you have an Android device you can download the .apk file directly from here:
http://mccormick.cx/dev/Aurioid-debug.apk
Try putting the Pd message "freq 220" into the textbox to get a taste for what is going on.
Just to re-iterate what it is. This is Pd for Android with a WebKit front-end. It should make it simple for media people to build Pd + HTML/javascript instruments and package them as redistributable Android apps. The audio backend is Pd patches, and the interface frontend is regular old HTML, CSS, and javascript files.
The HTML/javascript is in "assets/index.html". The Pd file is in "res/raw/test.pd".
To send a message to Pd you use the Javascript call "pd.send('my message');" which is received by the receiver named '[r gui]' in your Pd patch.
To send a message from Pd to the front end, use the sender '[s android]' which calls the Javascript callback "pd_receive(msg)" in the frontend.
There seems to be some latency between the frontend and Pd.
An example of what you could do with this: set up some HTML toggle boxes, and use them to control a beat in Pd. Pd could send back a 'tick' to indicate which toggle it's currently up to.
You can also trivially change the icons and name of the app if you wanted to release your own Pd patch as a branded Android app.
I would love to build some Android-Pd-HTML-Javascript instruments now, but it's 2am here and I have to work tomorrow.
Goodnight!
Chris.
PS incidentally, here is the Android device I am using: http://www.merimobiles.com/Witstech_A81_E_Android_2_1_WinCE6_0_Free_Case_p/meri0306.htm It has many flaws but it is playing simple Pd patches ok. :)
PPS Note on the license: I would love to release my contribution (Aurioid.java) as GPLv3 but since it's 90% Peter's code, based on PdServiceTest.java with some WebKit thrown in, I am not sure if it's within my rights to change it from BSD. Opinions?
[Deeply ironic that you can't do this on an iPhone/iPad/iPod even though Jobs is jonesing for HTML5. No problem. Keep your walled garden.]
