An interactive Bash function that allow you to select an Android device in a list then Sets ANDROID_SERIAL

adb-setdev.sh

# Display a list of all connected Android devices
# Set ANDROID_SERIAL environment from selected item
# Example of use : # adb-setdev && adb install -r myapp.apk
function adb-setdev()
{
    devices=($(adb devices|grep "device$"|cut -f1))
    devices_count=${#devices[*]}
    if [ "$devices_count" -eq "0" ]
    then
        unset ANDROID_SERIAL
    elif [ "$devices_count" -eq "1" ]
    then
        export ANDROID_SERIAL=$devices
    else
        # Ask for a device to select
        declare -a named_devices
        for device in ${devices[*]}
        do
            name=`adb -s $device shell ls | grep fstab | cut -f2 -d\.`
            named_devices+=("${device}/${name}")
        done

        select named_device in ${named_devices[*]}
        do
            device=`echo "${named_device}" | cut -f1 -d/`
            export ANDROID_SERIAL=$device
            break
        done
    fi
}

This modification adds the device type to the output... at least on the devices I have handy. It looks for a file "fstab.X" and displays <device_serial>/ in the menu. This makes it easier to pick the right device if you have different types of devices and don't know all of their serial numbers.
