Once I try to run the app, a box pops up and says "Unfortunately, Hello has stopped" on the simulator.

Once i try to run the app, a black box with white text pops up and says "Unfortunately, Hello has stopped." on the simulator. "Hello" was the name of the project I created. I looked in the logcat and this is what was shown. I don't exactly know what i'm suppose to look at.
