1)  You could dump the result in a file after the toast:

f = open("myfile", "wb")
f.write(str(average))
f.close()

You can use also pickle module to dump more complex data structure:
http://docs.python.org/library/pickle.html

2) You can dump the result in a database:
http://docs.python.org/library/sqlite3.html

3) you can post the result to the SL4A server, using you own facade to
manage it: https://code.google.com/p/android-python27/wiki/TutorialHowToCreateCustomRpcFacade

I would use 3)
