How to sell an idea or application for Android?

It’s no secret that you can make money on a good idea, but it’s not as easy as it seems.
In particular, if you look in the direction of Android applications, then after writing the program you need to attend to the issue of getting into the Android Market. As well as issues of advertising promotion of its program.
Most do not bother with such questions and work through publishers who promote and register your program in the Android Market.



Now actually, in fact. Now you can chat with one of the western publishers of applications for Android. Personally, I am far from programming for Android and I cannot ask any specific questions.
Therefore, I would like to ask for help from habro users. What questions are interested in a developer for Android? Maybe there are suggestions for improving partnership schemes with the publisher?
I will collect questions and make an article-interview, which will be very useful for those who decided to make their lives easier and not bother with the nuances of promoting and publishing their programs.
