Android programming on Linux

Setup your development environment

• install the Java Development Kit (JDK)

  # On Redhat or Fedora run the following
  
  yum install java-1.7.0-openjdk
  yum install java-1.7.0-openjdk-devel

• install the android sdk:

  http://developer.android.com/sdk/index.html

• adjust your path environment variable

  # echo 'export PATH=$PATH:/home/fox/android/tools:/home/fox/android/platform-tools' >> ~/.bashrc
  echo 'export PATH=$PATH:/path/to/android/tools' >> ~/.bashrc

• optionally install eclipse

• create an ADV (android virtual device) emulator

Tip: Add the platform-tools/ as well as the tools/ directory to your PATH environment variable.

Create an android project on the cli

reference: http://developer.android.com/guide/developing/projects/projects-cmdline.html

The following cli command will create an android project skeleton named HelloWorld in your home directory.

android create project \
   --package com.example.helloworld \
   --activity HelloWorld \
   --target 3 \
   --path ~/HelloWorld

target

The "build target" for your application.

This corresponds to an Android platform library (including any add-ons, such as Google APIs) that you would like to build your project against.

To see a list of available targets and their corresponding IDs, execute: android list targets.

name

The name for your project.

This is optional. If provided, this name will be used for your .apk filename when you build your application.

path

The location of your project directory.

If the directory does not exist, it will be created for you.

activity

The name for your default Activity class.

This class file will be created for you inside <path_to_your_project>/src/<your_package_namespace_path>/ .

This will also be used for your .apk filename unless you provide a name.

package

the package namespace for your project

This will follow the Java programming language standards.

Programming the HelloWorld project

modify your source code...

Building and running from the command line

Reference: http://developer.android.com/guide/developing/building/building-cmdline.html

The Ant script compiles and builds your project into a .apk file which may be installed on an emulator or device.

Ant provides the following two build modes:

• Test or Debug (Development)
• Release (Production)

Regardless of the build mode chosen the application must be signed before it can be installed on an emulator or device.

In development (debug mode) the SDK will automatically sign your project with a development key. An application signed with a development key cannot be distributed.

In production (release mode) the SDK will not sign the .apk file, you will need to do this manually using the Keytool and Jarsigner.

Building in debug mode (development)

1. Navigate to root of the project

2. Compile the project using Ant.

   ant debug

Install debug application to emulator

1. Start your AVD (android Virtual Device) emulator.
2. Install your application using the adb script which exists in the platform-tools/ directory of the SDK.

adb install ~/HelloWorld/bin/HelloWorld-debug.apk

You might need to specify the device serial which is found on the top of the virtual device titlebar.

adb -s emulator-5554 install ~/HelloWorld/bin/HelloWorld-debug.apk

A top secret command for both building in debug mode and deploying to a running emulator use the following command:

ant install 

How to update Android SDK

Periodically you may want to update your development environment, here's how:

• open a Terminal (ctrl+alt+t)
• type 'android' and press enter
• click the 'Installed packages' tab
• click the 'Update All...' button

Installing Scala

Not directly related to Android development, but I plan to learn Scala (expand my use of functional langs) while building android apps. Replace version with latest in the subsequent code block.

# download & unzip
wget hhttp://www.scala-lang.org/files/archive/scala-2.11.0.tgz
tar -xzvf scala-2.11.0.tgz

# install
sudo mv scala-2.11.0 /usr/share/scala
sudo ln -s /usr/share/scala/bin/scala /usr/bin/scala
sudo ln -s /usr/share/scala/bin/scalac /usr/bin/scalac
sudo ln -s /usr/share/scala/bin/fsc /usr/bin/fsc
sudo ln -s /usr/share/scala/bin/scaladoc /usr/bin/scaladoc
sudo ln -s /usr/share/scala/bin/scalap /usr/bin/scalap

might need sbt (scala build tools)

libGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, Mac OS X, Android, your WebGL enabled browser and iOS.
