A short script to perform auto install on multiple Android devices by watching a specific folder for an .apk write. Usage: ./continuous_deploy.sh com.example.package/.MainActivity

continuous_deploy.sh

folder="bin/classes/"
package="$1"

inotifywait -m -q -e close_write "$folder" | while read f; do 
    # take only the filename
    f=`awk '{print $3}' <<< "$f"`

    # rebuild the full path
    path="$folder$f"

    # if it's not an apk or is the unaligned one, skip it
    if [[ $f =~ ^.*unaligned\.apk$ || ! $f =~ ^.*apk$  ]]; then
        echo "Skipping $f"
        continue;
    fi

    # Get the list of device names. This ignores whether they're online or not.
    devices=`adb devices | sed '1d' | awk '{print $1;}'`
    echo "Sending $f.."
    echo "$devices" | (parallel adb -s {} install -r "$path" | sed 's/^/   /') 2> /dev/null
    echo "done"

    # If we provided an activity name, start it on all devices
    if [ $package ]; then
        echo "Starting activity $package.."
        echo "$devices" | (parallel adb -s {} shell am start "$package" | sed 's/^/   /') 2> /dev/null
        echo "done"
    fi
done
