Imagine that you have ordinary Chinese android box with simple remote controller. What YouTube client you should use? Regular client doesn't understand remote controller. Off course you may use official YouTube TV client for Nexus Player. But there is many drawback. One of them is dependencies (e.g. gapps) that box usually don't have. Another drawback is that official client needs minimum Android 5.0. And there comes Smart YouTube TV. It require zero dependencies, minimum Android 4.4.

• consist of two parts: app and standalone browser engine:
  • smartyoutubetv: main app that using browser engine for rendering
  • browser: engine with wide capabilities (e.g. display naked page)
• browser engine can be used independently (currently in development)
• browser engine based on marshmallow-release branch of android open source project

To build project navigate to the root directory then type:

gradlew build

Generated apks will be placed in the directory ./smartyoutubetv/build/outputs/apk/

MyActivity extends MainBrowserActivity {
	@Override
	void onCreate(Bundle bundle) {
		super.onCreate();
		Controller controller = new SimpleUiController(this);
		controller.loadUrl("http://ya.ru");
		setController(controller);
	}
}

MyActivity extends MainBrowserActivity {
	MyActivity() {
		// set preferred engine to XWalk (default - WebView)
		// we must set engine as early as possible
        Browser.setEngineType(EngineType.XWalk);
	}
	@Override
	void onCreate(Bundle bundle) {
		Controller controller = new SimpleUiController(this);
		Intent intent = (bundle == null) ? getIntent() : null;
		controller.start(intent, "http://ya.ru");
		setController(controller);
	}
}

• ability to choose preferred engine type: WebView, XWalk
• you don't have to deal with creating custom methods for managing WebView lifecircle (pause, resume etc)
• ability to easily add tabs, settings and other regular browser-specific features
• all internal state is saved into persistent memory instead of RAM

• Crosswalk - alternative browser engine
• Otto - message bus
• OkHttp - http processing
• Android Logger - logger factory implementation
• Crashlytics - multipurpose crash analytics
• Butter Knife - simplify layout handling

Version name, code and package will be loaded from gradle build script. Crashlytics credentials can be controlled from fabric.properties file.

You can get apiSecret and apiKey from the fabric dashboard fabric.io/settings/organizations where they were created after successful first-time signup with Crashlytics plugin GUI for Android Studio.
