I tried to uninstall, I tried to force stop, restart phone, i cant clear cache, and it wont stop installing. The only option i can think of is to factory reset and i don't want to do that so any help would be fantastic!!!
I am having the same problem with the app 'DroidIn 4 LinkedIn'. I too have tried all of the suggestions in this thread and nothing has worked. I cannot get to the 'Cancel Installation' option.
