This spins off parts of 5620 to bake while we work through how to do the rest of libviewer.so -> viewer.apk.

-HelloSkia
-=========
-
-Intro
------
-
-This is a minimal Android app that uses JNI and Skia to do rendering.
-
-Setup
------
-
-These instructions need to be followed only once to setup your copy of HelloSkia. Path parts that
-are surrounded with curly braces should be replaced with the paths that are described.
-
-1. Follow the quick start guide on building Skia for Android.
-
-2. Copy {Skia root directory}/trunk/out/config/android-{your architecture}/{Relase or
-Debug}/lib.target/libskia_android.so into {HellSkia root directory}/jni/skia/libskia_android.so
-
-3. Copy {Skia root directory}/trunk/include into {HellSkia root directory}/jni/skia. This should be
-done so that the path {HellSkia root directory}/jni/skia/include is a folder that contains, to name
-just a few, the folders config and core.
-
-
-Building
---------
-
-The following assumes that the platform-tools directory of the Android SDK and the Android NDK
-directory are both on the system path. This also assumes that adb is working and connected with some
-device or virtual device.
-
-1. Open a terminal to the HelloSkia root directory and enter these commands:
-
-$ ndk-build # Builds the modules inside of jni/
-$ ant debug # Builds the Activity and packages it with all resources and modules of jni/
-$ adb install -r bin/HelloSkia-debug.apk # Installs the app onto a device
-
-2. To run the app, open your Android device's launcher and start the application labeled
-HelloSkiaActivity.

- To customize existing targets, there are two options:
- - Customize only one target:
- - copy/paste the target into this file, *before* the
- <import> task.
- - customize it to your needs.
- - Customize the whole content of build.xml
- - copy/paste the content of the rules files (minus the top node)
- into this file, replacing the <import> task.
- - customize to your needs.

- ***********************
- In all cases you must update the value of version-tag below to read 'custom' instead of an integer,
