Choose Your Poison

The easiest way to develop Android application is to use Android Studio. So this is about how to manually use different build system.

I know 3 different build system for Android:

• Ant
• Gradle
• Maven

These are general purpose Java build systems that can be adopted to help you build Android. I believe Android Studio uses Gradle.

Android SDK

If you are not going to use Android Studio, you have to get the android sdk components.

• Android SDK and related packages.
• Android Debub Bridge(adb) part of android studio project.

Getting these components on your system might be difficult, best to consult with your distribution.

My Build Script

Below is my build script for building android application using Gradle. You might run into problems with setting up create project because of dependencies and out-of-date settings. The other tough one might be debug depending on your build system. Check out JUnit.

#! /usr/bin/sh

cmd=$1
device="-s emulator-5554"

#device="-s 20080411"

path="oauth"
pkg_file="./build/outputs/apk/"$path"-debug.apk"
src_path="./src"
debug_port=8700

if [ $cmd = "create" ]; then
	android create project \
