you are calling:
Using java Syntax Highlighting
Parsed in 0.011 seconds, using GeSHi
and your main.xml doesn't contain a TextView.
This is probably a problem with the emulator, that it doesn't update your application on the emulator.
Run your project once with "-wipe-data" (use the search to find where to put it).
That will reset your emulator and wipes all problems related to it away.
