IDE Build Environment for Android Studio

This page discusses how to build the Magic Lantern IDE for Android titles using Eclipse and Ant.

[TOC]

Dependencies

This section identifies dependencies for building the Magic Lantern IDE.

1. Microsoft Visual Studio C++ v6.0 is installed with Service Pack 6 applied or Microsoft Visual Studio 2005 is installed with Service Pack 2 applied.
2. Eclipse for RCP/Plug-in Developers, version 3.7 (or later)
3. Apache Ant, version 1.8.0
4. Oracle Java Development Kit (JDK), version 1.6.0_16

Assumptions

These instructions assume the following

• The dependencies above are installed under a Windows drive labeled "M" (e.g. M:).
• The Magic Lantern software has been downloaded into the "M:\projects\MagicLantern" directory and the MLE_HOME environment variable is set to "M:\projects\MagicLantern".
• You already know how to use the Eclipse IDE
• You already know how to create and use Ant build scripts

Environment Variables

MLE_HOME Environment Variable

Set the variable MLE_HOME to reference the home of the Magic Lantern source. This document assumes that it is set to "M:\projects\MagicLantern".

MLE_ROOT Environment Variable

Set the variable MLE_ROOT to reference the root directory where the Magic Lantern components will be installed. This document assumes that it is set to "M:/projects/MagicLantern".

Note that this variable uses the UNIX-style path delimiter ('/').

MLE_WORKPRINTS Environment Variable

Set the variable MLE_WORKPRINTS to the root directory where Magic Lantern Digital Workprints can be located. This document assumes that it is set to //M/projects/MagicLantern.

The Magic Lantern Studio assumes that the Digital Workprints will be located under the $MLE_WORKPRINTS/workprints directory.

Note that this variable uses a canonical path style for the drive (i.e. //M/).

Build Plugins for Eclipse IDE

This section describes how to use Eclipse to build the Magic Lantern IDE for the Android Platform.

Each component provides an Eclipse project to facilitate building the component in Eclipse. To build a component, use the following instructions:

1. From the main Eclipse toolbar, select the "File->Import..." menu entry. This will display the Import dialog.
2. Select the "Existing Projects into Workspace" entry found under the General category.
3. Select the "Next>" button in the Import dialog. The dialog should now be displaying the "Import Projects" page.
4. Select a directory to search for existing Eclipse projects. Use the the "Browse..." button.
5. The "Projects:" widget should now be showing you list of existing projects that are rooted in the directory specified in the above step. Select the project(s) of interest.
6. To wrap-up the import, select Finish. The project will now be added to your Eclipse Workspace.

By default, Eclipse will build the component when the project is imported.

Build Android Runtime Engine Libraries

This section describes how to build the Android libraries for the Runtime Engine and title parts.

The library of components that are built include

Library	Component	Directory Location	Jar Description File
com.wizzer.mle.runtime	Core Runtime Engine Library	$MLE_HOME\Core\mlert\android\com.wizzer.mle.runtime	mlert.jardesc
com.wizzer.mle.math	Math Runtime Engine Library	$MLE_HOME\Core\math\android\com.wizzer.mle.math	mlmath.jardesc
com.wizzer.mle.parts	Parts Runtime Engine Library	$MLE_HOME\Parts\base\android\com.wizzer.mle.parts	parts.jardesc
com.wizzer.mle.parts.actors	Actors Runtime Engine Library	$MLE_HOME\Parts\actors\android\com.wizzer.mle.parts.actors	actors.jardesc
com.wizzer.mle.parts.mrefs	Media Reference Runtime Engine Library	$MLE_HOME\Parts\mrefs\android\com.wizzer.mle.parts.mrefs	mrefs.jardesc
com.wizzer.mle.parts.props	Properties Runtime Engine Library	$MLE_HOME\Parts\props\android\com.wizzer.mle.parts.props	props.jardesc
com.wizzer.mle.parts.roles	Roles Runtime Engine Library	$MLE_HOME\Parts\roles\android\com.wizzer.mle.parts.roles	roles.jardesc
com.wizzer.mle.parts.sets	Sets Runtime Engine Library	$MLE_HOME\Parts\sets\android\com.wizzer.mle.parts.sets	sets.jardesc
com.wizzer.mle.parts.stages	Stages Runtime Engine Library	$MLE_HOME\Parts\stages\android\com.wizzer.mle.partsstages	stages.jardesc

To build the Java archive, JAR, file for each component, do the following:

1. In Eclipse, open the Jar Description File (e.g. mlmath.jardesc) for the corresponding component by double-clicking on the resource in the Package Explorer view. This will bring up the "JAR Export" wizard.
2. Select the "Next>" button which will display the "JAR Packaging Options" dialog page.
3. Deselect the "Save the description of this JAR in the workspace" button.
4. Select the "Finish" button. The corresponding component JAR will be generated and placed in $MLE_HOME/lib/android-10.

Ant Build Environment

This section describes how to use the Ant build scripts to build the Magic Lantern IDE for the Android Platform.

Update PATH Environment Variable

Building Android outside Eclipse involves using the command line or shell.

Make sure that the "tools" and "platform-tools" folder of the Android SDK installation directory are part of your PATH environment variable.

Create Ant Build Scripts

The Eclipse project generation wizard does not create the required Apache Ant build.xml file. You can generate it from the command line.

To create the Ant build.xml script for the following Magic Lantern projects:

com.wizzer.mle.math

• cd $MLE_HOME/Core/math/android/com.wizzer.mle.math
• execute "android update project --path ."

com.wizzer.mle.runtime

• cd $MLE_HOME/Core/mlert/android/com.wizzer.mle.runtime
• execute "android update project --path ."

com.wizzer.mle.parts

• cd $MLE_HOME/Parts/base/android/com.wizzer.mle.parts
• execute "android update project --path ."
