Release 0.8 page (https://sourceforge.net/projects/gpsmid/files/gpsmid/Release%200.8/) contains debug .jar and .jad files.
But WTK emulator rejects .jad because it references non-debug names:
MIDlet-Name: GpsMid-Generic-full
MIDlet-1: GpsMid-Generic-full,/gpsmid.png,de.ueller.gpsmid.ui.GpsMid
MIDlet-Jar-URL: GpsMid-Generic-full-0.8-map72.jar
The third one has to be changed to launch WTK emulator.
No idea about the second.
The first one has to be without -debug part (should be equal to some string in a .jar file and this line is without -debug part) or WTK won't accept it too.
Should -debug builds be put into a separate folder and have names without -debug part, or should be they patched deeper to have -debug part in all places - no idea.
Cleanest thing probably would be to be have them in a separate folder - the debug ones are built so the build-time name is without "-debug", then renamed to -debug.
There's also quite a bunch of files - would be easier for user to find the needed ones if they were divided to subfolders by device OS.
Maybe for 0.8.1 we'll have j2me, j2me-debug, android & android-debug for the GpsMid*.ja? and *.apk files.
