If your Android based DAP runs actual Android apps, its pretty simple to check to see that the Playlist Settings need to be in Dapper.
The key is running the DAP in Android mode and then downloading and running "ES File Explorer" to see what your DAP thinks it's cards names are:
Boot the DAP in Android modeDownload/Install ES File Explorer (I believe it may also come installed on a lot of DAPs)
Run the Explorer app.
At the top of the screen you will see some text showing you where ES File explorer currently is looking at your storage. It is in blue on the top left next to the list button that looks like three lines. Mine shows Playlists:
Tap that entry and you will see a list of storage areas pop up with little SDCard icons to their left:
We're interested in the last two - the ones that refer the the major storage of your DAP. This is either the internal and external storage or in the case of a dap with 2 cards, its going to be the last two entries - in the above case sdcar - the two cards.If you select one of them you will see in the top bar of the aand sdcard2.
Select the first storage area you would use for your DAP. once again, for a DAP with internal storage and 1 drive its probably doing to be the first in the list.
For a DAP with two SDCards, its likely going to be the one that references the first SDCard - in the above case this is clearly sdcard1
Once you have selected it you can see in the bar at the top the actual name the DAP uses to refer to the card.
Above you see / > storage > sdcard1
So, in Dapper under card 1 I would type in: /storage/sdcard1
If you do the same for the second card I see:
And that entry for Card 1 in Dapper is therefore /storage/sdcard2
In fact when you're done with this and you hit the select button again you'll see the list of the storage areas you had selected in the history list, which for me was /storage/sdcard1 and /storage/sdcard2
I put those in the Playlist Format settings in Dapper: (See bottom right of the image below)
