Chris McCormick has done a wonderfull android app, it enable you to run your pd patches on your android smartphone and play with them anywhere, provided that you keep it vanilla.

1- Go there : http://droidparty.net/
and download the apk on your PC

2- Download the attached zip, (it's a tested and working patch.) unzip it on you computer.

3- Search File Expert on the android market and install it (https://market.android.com/details?idxcxin.filexpert)

4- Once file expert is installed, fire it up, and click on Share (in the bottom line) -> choose "enable web sharing" (this will share your sdcard localy). A message appears and gives you info such as an adress, a username and a password (remember it, or keep it displayed onto your phone)

5- On your pc, launch your preferred browser enter the adress, it will prompt you for usename and password.

6- Double click on the big icon, and you have access to your SDcard.

7- Create a folder of you choice (right click -> New Dir), enter it and upload the apk (right click ->upload). Once the upload finished, just click the uploaded file it will install on its own.

8- Go back to the root folder of the SDcard, create a new folder of you choice to put your patches (say "Pure-Data"), enter it. Create a new folder called XY-Pad, and upload all the files from the zip in this folder. "droidparty_main.pd" is the main patch you can have a look at it on your PC first.

9- Close File Expert on your phone by pressing back several times, and launch PdDroidParty it will find your patches on its own.

10- Have Fun !

note : I choose to use an app to share you sd card wia wifi (because it's faster than pluging and mounting your phone each time you want to test something), but you can of course use USB cable to do all the transfers beetween phone and computer. But you'll need a file browser anyway to install the transfered apk

edit : you need to authorize non-market apps to be installed. Just go in Parameters -> Application and check the first box (something like "authorize non-market application")

@Cristian

• create a folder called 'patch' and put your patch (which has to be named as "droidparty_main.pd') into it
• './pack-patch' is a bash script, if you wanna see what it does open it with a text editor and try to read it.
• if you cannot run './pack-patch', .zip your patch folder and put it into res/raw directory
• README.txt resides in the main folder called MySynthesizer

I am stuck at the starting gate. When I run PdDroidParty on my Samsung tablet it finds no compatible apps. So all I have is a black screen with a message at the top. There seems to be no way to put in a search path.

I have a folder on my internal SD card named pdDroidParty. In it are the three folders created by the demo, test, and abstractions archives. I would assume that at least these would be found!

Thanks for any help.

If some people are still trying to publish apps from pddroiparty I would advise to look here :

http://forum.pdpatchrepo.info/topic/9753/ppp-pure-data-libpd-based-jamming-system

Is it possible to manually edit data structures in droid party?

I think it's not possible.

Data structure are not supported in the sense that there is no class to display them as gui elements on the android side.

Dan Wilcox at pd-party (ios version) as listed this as a possible future feature. It's probably something that would be interesting but may require a consequent amount of work.

What would you like to do that isn't possible to do yet ?

I'm interested in being able to manipulate graphics on touchscreen devices as a control interface for a patch

something like what was done in plasma sound?

Looks interesting. I'll check this out. thanks

There is actually several options here

• either you are a developper so you can directly use libpd as an audio engine, and use the api to send or receive data from your patch to/from you favorite language (c# c++ java etc.) you can then create your ui in this programming language. Plasma sound uses a mix of android specific code and the processing-for-android drawing api. With this method you need to use something like eclipse or android studio but you can create binary signed apps that you can upload to the android store. (it works great, I've published several apps with this combination).

• either you want to stick with pd :
  1- pddroidparty will run your patch in a specific android app emulating the pd gui with a few additions (touch surface etc.), the sources from Chris target android only. But Pd-party by danomatika will target ios soon (now beta I think).
  2- mobmuplat is also a very neat project, where you can do probably a little more with the graphics. android and ios.
  3- sceneplayer on android is also a way to read patchs on android, it provides a way to display/hide and move images too. It target android, the ios version rjdj is sadly long lost.
  4- ppp mentionned before, will help you publish app using pd as a wysiwyg editor in the same way of pddroidparty, but you'll end up with a signed binary ready to distribute. It also packs a midi clock shared via wifi to sync several apps with one another.

I think it sums up all the options here.

So back to data-structures : data-structures are in libpd, but none of the projects above supports them to my knowledge, you can't display or interact with them. If you program you can probably access them through libpd, draw/manipulate them in the programming language of your choice.

Hey there! I'm using a Huawei P9 Lite with Android 7.0
If you guys don't see any patches in your installed PdDroidParty app, try to put the files on your internal storage. PdDroidParty did not see the folders on my SD card and every source on installation says that you should make a folder on your SD card. Maybe this is because of newer version of Android, I don't know. Anyway it works like charm, if anyone wants to get started with this, definitely check out the demo, test .zip files!
