Hello and thanks for the reply. No, the FieldGuide line that is commented out does not cause the crash. To the contrary, it actually works properly when starting that activity in the main app. Below you are looking at the code that causes the crash (the geotest activity). I had all of the below code in another application with other activities, and everytime I tried to start this activity, it would crash. So in an effort to isolate the problem, I made a new Android project and put only the crashing activity in it, and it is still crashing (which allows me to rule out the other activites/code in the main app for causing the problem). I get a nullpointerexception when trying to start the activity (see logcat output below). I'm very curious if someone else copy/paste all the code below into a new project, do they have the same problem?
