PdDroidParty is an open source Android app you can use to run your Pure Data patches on Android. Simply copy your Pd patch onto your device's storage. You get a list of all of the Pure Data projects on your device's storage and you simply select the one you want to run.

The way it works is you create a special patch called droidparty_main.pd in your project folder and then copy the whole folder onto your device storage. PdDroidParty will show you a list of all of the folders containing a droidparty_main.pd file and when you choose one the patch will be loaded. When you run the droidparty_main.pd patch the user interface will be emulated by PdDroidParty and can be themed with SVG widgets.

You can also create a native Android app from your Pd patch using PdDroidParty. More information is available at the website.
