I am about moderately experienced but in c/winapi got not a knowledge of android , I am searching for some open source android game source I could look on (online or download, preferebly online) and study for learning purposes, something small with no opengl etc just basics or maybe something a bit bigger - but just native core api of android to get some idea

(i would like to learn android not external libs)

maybe someone could provide some links to such things, I got a bit trouble to find something and i am totally blank page in android environment

When it comes to Android development, the decision will have to be made whether or not you are going to go the native route, or use Java. With that said, if you choose the native route, then having the C experience will carry over somewhat. At a higher level there isn't much difference between a native Android application ( developed with the NDK ) and a application you would develop in C ( ..this is a gross oversimplification, but serves to illustrate that there is no secret sauce to Android programming ). There is online documentation for the NDK so you could probably start from there before jumping into a full fledge Android game( regardless of its complexity ).

Typing in "android game source code" into Google brings up a first page with huge repositories of source code, and large collections of games with source. They range from tic-tac-toe to fairly complex games. Sites range from Google code repositories, to tutorial sites, to broad lists of open source projects. One of the first listings is even a step-by-step tutorial to build a flappy birds clone, complete with source listings and graphics.

Is there some specific reason that search engine results are not good enough?

I dont know, I searched a bit (more under the "android tutorial " though) but this what i find doeas not fitted my needs

android sin is this that i like to program from something very simple one line to run then build it up to two lines and run then 5 lines 10 lines 15, 20, 30 lines etc

android makest this entry point not point but large pool of config files and other things I dont know

So i was started thinking that maybe it would be better for me to start for looking at this entry "point " in the form of some small game - it would be quicker maybe

As to sources even if i found something in google it is not bad for me to chat with some people fellows maybe they will suggest me something (I often do things this way - it may be not speed optimal, as chatty way etc, but I prefer slow programming where i can find more time for some ideas maybe and a bit down the killing tempo ,)

Bit later found something called PongTime

https://github.com/tinkerlog/PongTime

this seem to be easy enough, i will be studying it tmorrow
