-- 1. Prerequisites --

Do steps 1-4 before git clone.
Step 5 is included in the source code. Skip it.

1. Android SDK
http://developer.android.com/sdk

2. Android Kernel
git clone git://android.git.kernel.org/kernel/common.git
// qemu kernel
// git clone git://android.git.kernel.org/kernel/qemu.git

3. ARM Compiler
http://www.codesourcery.com/sgpp/lite/arm

4. Goldfish
cd <KERNEL_ROOT_FOLDER>
git branch -a
git checkout remotes/origin/archive/android-gldfish-2.6.29
// qemu kernel
// git checkout remotes/origin/android-gldfish-2.6.29
cat arch/arm/configs/goldfish_defconfig

5. Config & Makefile
create and start an AVD

cd <KERNEL-ROOT-FOLDER>
adb pull /proc/config.gz
gunzip config.gz
mv config .config
// qemu kernel
CONFIG_MODULES=y

change 2 lines in Makefile:
ARCH ?= arm
CROSS_COMPILE ?= arm-none-linux-gnueabi-

6. Compile
make goldfish_defconfig
make

on sucess:
Kernel: arch/arm/boot/zImage is ready

7. Emulator
ae <AVD>

-- 2. .bashrc References --

alias agcc='arm-none-linux-gnueabi-gcc'

-- 3. Let 2 emulators talk --

Suppose the AVD for the host and guest OS are 'host' and 'guest' respectively.
The emulators are 5554 and 5556 respectively.

1. Run the host and guest OS
aes host
aes guest

2. Push TCP client and server
cd tcp
make
make install

3. TCP forwarding
adb -s emulator-5556 forward tcp:7000 tcp:7000

4. Sending from host OS (client) to guest OS (server)
adb -s emulator-5556 shell /data/server 
adb -s emulator-5554 shell /data/client msg

-- 4. Using avmt.sh --
The server is written into the ramdisk for guest OS and starts automatically from init.rc.
There's no need to push it to guest OS manually.
With the avmt shell script, part 3 becomes simpler.

1. Run the host and guest OS
./avmt host
./avmt guest

2. TCP forwarding, client compiling and pushing
./avmt setup

3. Sending from host OS (client) to guest OS (server)
./avmt send msg

4. Unzip and zip ramdisk
./avmt unzip-ramdisk
./avmt zip-ramdisk
