Hi there,
I was working on the code below, trying to load all available videos
from the emulator sdcard into my gridview, I compiled and wanted to
test it, but the app has disappeared entirely from my emulator... what
can I do or better what have I done wrong in the code that could cause
a problem like that...???
I could really need some help, so if anyone may see what I have done
wrong, please tell, because I have no idea what's wrong...Thanks in
advance...
