Main

public class Main extends Object
This is a set of tests that loads all the framework resources and a project checked in this test's resources. The main dependencies are: 1. Fonts directory. 2. Framework Resources. 3. App resources. 4. build.prop file These are configured by two variables set in the system properties. 1. platform.dir: This is the directory for the current platform in the built SDK (.../sdk/platforms/android-). The fonts are platform.dir/data/fonts. The Framework resources are platform.dir/data/res. build.prop is at platform.dir/build.prop. 2. test_res.dir: This is the directory for the resources of the test. If not specified, this falls back to getClass().getProtectionDomain().getCodeSource().getLocation() The app resources are at: test_res.dir/testApp/MyApplication/app/src/main/res
