What is Vulkan

Vulkan is a low-overhead, cross-platform 3D graphics and compute API.

Vulkan targets

Vulkan targets high-performance realtime 3D graphics applications such as games and interactive media across multiple platforms providing higher performance and lower CPU usage.

Libraries

JarJar'd OkHttp Dependencies

Due to a bug in the packaging of Android OS "L", dependencies which reference Okio need to be repackaged.

For more information see square/okhttp#967

Usage

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	/**
	* Downloads all android-all dependencies and copies them to the mavenLocal() repository
	*
	* Once applied to your gradle project, can be executed with ./gradlew robolectricSdkDownload
	*/

	import java.nio.file.Files

	// The general idea of this was borrowed from https://gist.github.com/xian/05c4f27da6d4156b9827842217c2cd5c
	// I then modified it heavily to allow easier addition of new SDK versions

	def robolectricVersion = '3.3'

	def androidSdkVersions = [
	'4.1.2_r1-robolectric-0',
	'4.2.2_r1.2-robolectric-0',
	'4.3_r2-robolectric-0',
	'4.4_r1-robolectric-1',
	'5.0.0_r2-robolectric-1',
	'5.1.1_r9-robolectric-1',
	'6.0.0_r1-robolectric-0',

	public class AndroidApplication extends MultiDexApplication {
	public static final String TAG = AndroidApplication.class.getSimpleName();

	@Override
	public void onCreate() {
	super.onCreate();
	registerComponentCallbacks(new ComponentCallback());
	}

	private class ComponentCallback implements ComponentCallbacks2 {

	Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21.
	To use the support version of these attributes, remove the android namespace.

	For instance, "android:colorControlNormal" becomes "colorControlNormal".

	These attributes will be propagated to their corresponding attributes within the android namespace
	for devices running Lollipop. Any exceptions to this will be noted by including the "android:" prefix.
