i found a few related posts on this forum, but none of the suggested solutions worked for me.
the problem seems to happen for others as well.

i have PdDroidParty running on my Galaxy A3, Android Version 5.0.2.
i put the test files from http://droidparty.net/ onto my sd card in a folder called
PdDroidParty but the app does not find any patches.
i only see a black screen with "PdDroidParty compatible patches found:"
"finding patches" is performed at startup but the screen stays empty.
i tried other locations for the pd-patches and naming the folder differently according to my web-searches with no success.
any help please?

the patch to be loaded should be called droidparty_main.pd is that the case in your setup ?

the path to this patch should be :
/sdcard/PdDroidParty/MyPdPatch/droidparty_main.pd

and the patch will be listed in the app as 'MyPdPatch' if everything goes right

thanks for the reply.
but yes i tried with this path (even naming a folder sdcard)..!
see attached screenshot.
in the meanwhile i also tried on other phones with the same result.
is there any way to do a manual browsing to the folder?
or other kind of trouble shooting?
thanks

Strange behaviour, did you try with other patches or the same patch on another phone?
If you cannot solve the problem try to ask Chris Mccormick. Once I had an issue with PDDroidParty and I contacted him directly and he answered me solving the problem. He's a nice guy! cheers

what a good advice (;
chris told me to try saving the patches on the phone instead of the sdcard.
this works now :: a folder in the root directory of the phone called PdDroidParty

also i post a message from mxa on GitHub:
AFAIK Android versions 4.1(?) and up only allow apps to read and save data from the SD-Card which are in their folders, which is SD-Card/Android/data/net.droidparty/ or similar

thanks to all

THANK YOU KLAUSF! I spent hours trying to figure out why it wouldn't work for me. I was moving that PdDroidParty EVERYWHERE all over my phone with no luck. I wasn't smart enough to try the most obvious choice of the main directory.
