I want to create a shake answer for call, Android OS
<p>If to look over the internet the are a lot of applications for Android OS, that provide a shake feature, mean when someone is calling, you can just shake a phone and answer. As I know It is a work with sensors and about sensors I do have some informaiton, how to gather info and etc. 
My question is how to connect my app or maybe it will be service, to android phone call system? 
About my programming for Android I can say that im a new here.</p>

<p>Any information, any, I will be glad to read.
Thank you.
