For reminding myself.

• Make sure you have JAVA SDK installed and JAVA_HOME, JRE_HOME, PATH configured.
• Download android studio
• Add android_studio/bin to PATH, set alias for android_studio/bin/studio.sh for terminal startup. Put android studio binaries somewhere you have full authority.
• Download android SDK and other tools via SDK manager. Set ANDROID_HOME and add it to PATH.

• Android studio comes with Gradle in android_studio/bin/gradle/gradle-x.y. Setup GRADLE_HOME, add $GRADLE_HOME/bin to PATH.
• I prefer local Gradle to Gradle Wrapper, and choose the local one in preferences menu.
• I prefer local mavenRepository to jcenter, and use mavenLocal() in buildscript.
• Dependency:

buildscript {
    repositories {
        mavenLocal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}

• Moverio API is

ARToolKit is cool!

• Copy ARBaseLib code in the workspace, and in aRBaseLib/build.gradle apply android library plugin:

apply plugin: 'com.android.library'

• Make sure you compile the library prior to the app, add the following to app/build.gradle:

dependencies {
    compile project(':aRBaseLib')
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

ROS Android is awesome!

• Install rosjava_core first. This will create you a local rosjava maven repository.
• Compiling android_core from source is troublesome. An easier way is to clone the rosjava_mvn_repo to your local maven repository, add your local maven repository to your buildscript and you are done! Create ROS Android package as normal android package! Forget about rosjava_catkin!
• A sample top level build.gradle for ROS Android project:

buildscript {
    def rosMavenPath = "$System.env.ROS_MAVEN_PATH".split(':').collect { 'file://' + it }
    repositories {
        rosMavenPath.each { p ->
            maven {
                url p
            }
        }
        mavenLocal()
    }
    dependencies {
        classpath 'org.ros.rosjava_bootstrap:gradle_plugins:0.2.1'
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}
allprojects {
    group 'org.lcsr.moverio'
}
subprojects {
    apply plugin: 'ros-android'
    apply plugin: 'com.android.application'
}
defaultTasks 'assembleRelease', 'uploadArchives'

• Dependencies for a specific application in app/build.gradle:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'org.ros.rosjava_core:rosjava:0.2.1'
    compile 'org.ros.rosjava_messages:sensor_msgs:1.11.7'
    compile 'org.ros.android_core:android_gingerbread_mr1:0.1.2'
}
