Steps
* download and install GNU/ARM Linux tool chain
http://www.codesourcery.com/gnu_toolcha ... nload.html
* create C/C++ code. see below for sample code.
* build app without dynamic libraries using GNU/ARM Linux toolchain
ex. arm-none-linux-gnueabi-g++.exe -static -o hello HelloAndroid.cpp
* start emulator in Windows by double clicking on $SDK_ROOT/tools/emulator.exe
* in a Windows Command window, use "adb" to xfer executable to emulator disk
adb push hello /system/sbin/hello
* make your app executable; do not use chmod ugo+x
adb shell chmod 777 /system/sbin/hello
* run your app in a console on the emulator
adb shell
cd /system/sbin/
hello
