- added an example of the creation of new BazaarRequest

- changed test category id to "testCategory1022". The other was not
returning anything.

- There is no OnUiBazaarResponse class in the Android SDK. There is a
similarly named class in the sample apps that is used to do the thread
safe UI change for the TextView. I changed the MainActivity to
implement OnBazzarResponse interface and I moved the onResponse and
onException methods to the MainActivity class.

- small edit to the request.sendDisplayRequest method.

- added a TextView to make thinks cleaner and conform to Android
practices.

- put a couple more examples of code of the entire onCreate method and
MainActivity class.
