"Unfurtunately, Stealth has stopped" FATAL EXCEPTION: main

Regardless of the change I make, I still have no solution to this problem. The android emulator continues to appear on msg "Unfurtunately, Stealth has stopped". Being that on Main does not present any errors, but in the execution of FATAL EXCEPTION: main. All variants are declared correctly. Please kindly give me a light on this. Below I have xml and .java.
