How to compile APK from command line?

Create build.xml at project creation time

If you start a new project with:

android create project \
    --target 1 \
    --name MyName \
    --path . \
    --activity MyActivity \
    --package com.yourdomain.yourproject

the build.xml file used by ant will be generated.

The android tool is present in the tools/ directory of the SDK which you downloaded.

Create debug releases

Besides:

ant release

for final releases, you can also create debug releases with:

ant debug

Location of generated apk

Generated apk are placed under bin/.

The most important outputs are:

MyName-debug.apk
MyName-release.apk

but some intermediate apks are also generated, in particular unaligned and unsigned versions.

But most of the time you can forget where they were created and just run:

ant debug install
ant release install

to get them installed. But make sure it is working with adb first: adb devices command not working

Tested on Ubuntu 15.10, Android 23.

Android uses the Ant build system, so you can create a build.xml and build.properties file for your project.

You'll need to create the build.xml file first though:

android update project -p .

This will generate a build.xml file. You should probably customize the build steps and targets for your project. A good idea in your case would be to have the build.properties file generated by your website for the specific build... Then include it via the build.xml file. In particular, you will need to specify in the build.properties file where the signing keys are, and what the password is:

Build.Properties:

key.store=keystore.dat
key.alias=signing_key
key.store.password=password123
key.alias.password=password123

The build process using ant also allows you to do variable replacements in Java files, which might be another idea. It would allow you to customize the build process further on a client by client basis.

By default, the build is triggered by:

ant clean
ant release

Another neat idea: Have Ant copy the resulting APK file to a network share accessible by the website by placing a < copy ... /> line in the < target name="release" > section.
