Android and web client

Having problems with connection between web client (custom implementation) and android
web client sends offer in JSON sturucture, but android excepts it in string (like form demo.openwebrtc.org)

demo to android:

question

Is it in plans that android sdk also uses JSON structore not that string?

No files, tests, or entry points are named. Start by tracing how the Android SDK parses session descriptions and comparing that format with the web client's JSON examples; done should establish and document an agreed representation or a concrete compatibility change.
