As neo told above Dalvik VM does provide good interface to access GPS. Even that is the normally used
method when they do this on RPI like board too. Read his instructions. You could ask code examples on
android section.

>> Phone eke hardware architecture ??? ??? ???????? ??????? ??????

Why not? It's based on ARM9 or ARM5 and based on the ARM7 ISA set.
If you want to dig into this then you should read a good book on ARM Hardware system design.
This is the book that I'm using ,
ARM System
Developer’s Guide
Designing and Optimizing
System Software
Andrew N. Sloss
Dominic Symes

Learning curve is slow and you requires lots of patience, but it really worth learning it. Because ARM hardware
knowledge is specially asking on job advertisements. There is a professional certification on ARM too:
https://www.prometric.com/en-us/clients ... nding.aspx
Unlike SCJP this is really valid , because very few are doing such exam. And no classes/instructor who teaching
this course locally.

But if you need a video series [entry level ] then while reading that book you could go through this lessons too.
First year of ARM learning you don't need to buy any board , but second year you may need to buy something like
RPI. This is their first video in intro ARM video session,
[media]http://www.youtube.com/watch?v=PkOnQTwRoxw[/media]
It's all about self learning here.

First year you may need a good computer only with linux installed and you need to download the sources of
Qemu and Gcc and make ARM ports. The course will teach you how to.


In any case you want to read Android source , now we have a cross reference: [in the case you don't need
to download whole source tree].
http://androidxref.com/

If you are a beginner then you may find hard time to reverse engineer phone designed in close mind.
But there are some phones which are designed to hack in mind, They are explicitly designed to be hacked.
Life will be easy with such phone.

>> http://www.xda-developers.com/holiday-g ... e-of-2012/

and also xda forum have good source on RE android phones.
as well as this stack exchange : http://reverseengineering.stackexchange.com/ [used this to ask more general questions
on RE , use xda for asking more specific questions on android phones].


Service manuals and schematics are lots of good sources too: for a example.
Nexus Service manual + schematics : http://depositfiles.com/files/6kq0oh29f [posted orignally on xda forum]

Don't try to find a ARM processor reading schematics, you won't find it unless you will find a OMAP or TI chip
which have ARM processor integrated. Android operaring system and drivers should be ported into that chipset.
That's what android porting guys are doing.

So , many things here up to you, since I could give you a very very very little. I'm too so newbie to this field like you.

Lasantha ,
you are describing a 'daughter board' something like this:
http://www.mouser.com/new/microchip/microchipAC32001/

They were used on those cheap sensor networks.
I'm not sure that you would need something like to design your own hardware?
Then a FPGA daughter area is preferred. I think there are sensor arrays with that
daughter area. However I found that above link on the microchip network.
Feel free to ask from their product and sales engineers.
