Getting a constant crash on the emulator when running a specific activity in my android project. The main activity of the project, as well as the splash screen run perfectly. The activity I am trying to run is quite complex, with information being read from a phpMyAdmin database.
I have read through the LogCat, but cannot seem to pinpoint the error that is causing the crash. Any nods in the right direction would be much appreciated. Don't have too much experience with this type of stuff.
Many thanks and apologies for the messy LogCat.
