closed #79 it is a design decision of android not to show text in these
screen resolutions so dont let me fight with Android :) I can fight but
it is useless. so used a more proper solution. I changed the icon with a
next icon(previously done icon) and added title and subtitle.

resolves #80 added a function(isliveStreamExists) to server so android
client call this function and if it doesnt exists, it returns false. It
returns true if it exists.
