Another (in my opinion, less hassle) way to figure out what the exceptions are is to run the emulator in debug. When the exception gets thrown, Eclipse should fire a breakpoint at the current line. In debug mode, press F6 (to go to the next line) and in the Variables tab, there should be an entry for the exception. You can then inspect the exception to read the message to see what caused it.
