Main

public class Main extends Object
Entry point for the layoutlib_create tool.

The tool does not currently rely on any external configuration file. Instead the configuration is mostly done via the {@link CreateInfo} class.

For a complete description of the tool and its implementation, please refer to the "README.txt" file at the root of this project.

For a quick test, invoke this as follows: 

$ make layoutlib
which does: 
$ make layoutlib_create <bunch of framework jars>
$ java -jar out/host/linux-x86/framework/layoutlib_create.jar \
out/host/common/obj/JAVA_LIBRARIES/temp_layoutlib_intermediates/javalib.jar \
out/target/common/obj/JAVA_LIBRARIES/core_intermediates/classes.jar \
out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar
