Hey I just saw that I forgot s.th. within getCount(), so I changed it to
public int getCount() {
//return mThumbIds.length;
if(vidUris!=null){
return vidUris.length;}
return 0;
}
The thing now is that I still cannot see any videos displayed in my
GridView, but I get a message saying: "Sorry, but this video cannot be
played!"
As I don't want to play the videos but only display them in the GridView
like in an directory, do I maybe have to use MediaStore.Video.Thumbnails
instead, which I just found when I googled a little...though I don't know
what I should do with it in my code...if someone could help me out here,
that would be really really great... Thanks
