Java quickstart errors

[augustak]

There are some errors in the Java quickstart:

• codeblock 1: Client needs to be declared with a type

Additionally I think we should remove 'assertions' from the docs and instead show example output

[staalezh]

Client.createDocument should take InputStream as first parameter instead of a byte array.

Apache's HTTP library is not well supported on Android. The J2EEbl standard library has a HttpURLConnection-class that is also supported on Android. This is probably not a critical issue.

@staalezh These issues are relevant for the SDK repo. Can you post the issue there?
