# The base working dir is assumed to be $HOME/Android
mkdir $HOME/Android
cd $HOME/Android

# Download and unpack the SDK from
# http://developer.android.com/sdk/index.html
wget http://dl.google.com/android/android-sdk_r21.1-linux.tgz
tar xzvf android-sdk_r21.1-linux.tgz

# Add "platform-tools" and "tools" to the PATH
export ANDROID_HOME=$HOME/Android/android-sdk-linux
export PATH=$PATH:$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools

# List packages
android list sdk --extended

# Install packages. Use this same command line to update the packages
android update sdk --no-ui --filter platform-tools,android-17,sys-img-17,extra-android-support

# Check what targets are available
android list targets

# Create an Android Virtual Device (AVD)
android create avd --target android-17 --name android-17-x86 --abi x86

# Install "ant" to build packages
sudo aptitude install ant

# Create a Hello World application

# Build the App

cd $HOME/Android/Apps/MyFirstApp

# Start the emulator, hardware accelerated:
# http://developer.android.com/tools/devices/emulator.html#vm-linux
emulator -verbose -avd android-17-x86 -scale 0.9 -gpu on -qemu -m 512 -enable-kvm

# Install the App into an Android [Virtual] Device
adb devices -l
adb -s emulator-5554 install bin/MyFirstApp-debug.apk

# Launch your application from the HOST
adb -s emulator-5554 -e shell am start -a android.intent.action.MAIN -n com.example.myfirstapp/com.example.myfirstapp.MainActivity

# See logs, e.g. only errors
adb -s emulator-5554 logcat *:E

# Connect to the emulator via telnet if needed
telnet localhost 5554
