Plz help me...
Sorry you are having so much trouble, and also sorry for the delay in replying (I've been unable to check this forum for a while).
It looks like you are using a version of Python for Android (v3?) other than the one used in the book. The Py3k4a webpage describes their software as "beta", which you should read as an indication that it is not yet ready for prime-time.
Other readers have had similar problems with using versions of SL4A and Py4A that differ from the book. All of their problems went away whenever they matched the downloads and versions exactly to those in the book.
Unfortunately, I'm not in a position to try out the versions you are using myself. But, what's in the book does work.
