This project is an advanced native ads example intended to show how publishers might construct a list-based user experience (such as a news feed might have) that incorporates multiple native ad formats. The project uses a single activity that maintains a ListView and an array of items. Most of these items are mocked listings for real estate, which stand in example application data. Placed among the sample listings are AdPlacement objects. These objects us AdFetchers to request ads from DFP Custom Rendering, construct NativeAdView instances to display them, and cache references to individual asset views in AdViewHolders. Most of the AdPlacement classes handle a single type of ad. The MultiFormatAdPlacement, however, can request and display App Install, Content, and either of two custom template formats.

Tinting is set on a nine-patch drawable through the "tint" and "tintMode" parameters. A color state list is referenced as the tint color, which defines colors for different states of a View (for example disabled/enabled, focused, pressed or selected). Programmatically, tinting is applied to a Drawable through its "setColorFilter" method, with a reference to a color and a PorterDuff blend mode. The color and blend mode can be changed from the UI to see the effect of different options.

This sample uses Google Play Services Wearable Data APIs to communicate between applications on a phone and a paired wearable device. Users can create quiz questions on the phone, each of which has an associated DataItem. These DataItems are then received on the wearable, which displays them as notifications. Each notification contains the question as the first page, followed by answers as actions. When an answer is selected, the corresponding question's DataItem is updated, which allows the phone application to update the status of the question (i.e. did the user answer it correctly or not) and prompt the next question.
This phone application uses the enhanced notifications API to display recipe instructions using paged notifications. After starting the application on your phone, you can browse from a short list of recipes and select one to view. Each recipe is broken down into a number of steps; when ready, you can click on the START action in the action bar to send the steps to the wearable. On the wearable device, the steps are displayed as a multi-page notification, with one page for each step in the recipe.

This sample demonstrates how to create watch faces for android wear and includes a phone app and a wearable app. The wearable app has a variety of watch faces including analog, digital, opengl, calendar, steps, interactive, etc. It also includes a watch-side configuration example. The phone app includes a phone-side configuration example. Because watch face apps do not have a default Activity in their project, you will need to set your Configurations to "Do not launch Activity" for both the Wear and Application modules. If you are unsure how to do this, please review the "Run Starter project" section in the Google Watch Face Code Lab. For the Fit Distance related watch face, authentication IS a requirement to request distance from Google Fit on Wear. Otherwise, distance will always come back as zero (or stay at whatever the distance was prior to you de-authorizing the watch face). To authenticate and communicate with Google Fit, you must create a project in the Google Developers Console, activate the Fitness API, create an OAuth 2.0 client ID, and register the public certificate from your signed APK. More details can be found here. If the user has not installed or setup the Google Fit app on their phone and their Wear device has not configured the Google Fit Wear App, then you may get zero steps until one of the two is setup. Please note, many Wear devices configure the Google Fit Wear App beforehand.

The Wear component shows tourist attraction images and summary information, and provides quick actions for nearby tourist attractions in a GridViewPager UI component.
