I've answered in Stackoverflow. Cross-posting in different forums is normally considered rude. Also, this question has been answered quite a number of times in this list, and also in
Stackoverflow. Google is your friend :-)
KANDS has nothing to do with connecting to the demos, and I'm afraid that the first answer is still valid: you'll have to implement the signaling protocol of each demo yourself, if you want to have a native Android app. Please have a look at the documentation if you are a newbie to this, so you understand how the architecture that the tutorials are based on is. The one you've mentioned is the third one in this diagram
That's why KANDS won't help you, as KANDS was connecting directly to the KMS.
