Fire proactively brings your apps and content to customers with the enhanced home carousel.

Fire’s home screen includes several capabilities to help customers do things quickly. Beyond fast and predictable navigation with the right and left panels and the app grid, the home carousel helps customers get right back into your app.

Grabbing Your Customer’s Attention

The carousel widget enables you to expose content related to your app without the customer needing to launch your app. You customize the user interface to keep customers informed even when they’re not in your app and then, give them easy access back into your app.

Developers often track engagement metrics like 1-day, 7-day and 30-day retention and they work to increase the number of people that use their app day to day. Of course this starts with interesting content, but it’s also important to draw people back into the app using a devices services like Game Circle and Notifications . Now, with the release of Fire, there are two new ways to augment your app: Firefly and the Active Carousel Widget.

The Active Carousel Widget contains a list or grid and you can also configure it to show more information when the customer uses peek. The examples below show how a widget might look as a simple list or with more detail like icons, descriptive text or star ratings.

Beyond seeing information from your app, customers can also tap an item in the widget to launch your app. The widget communicates with your app through intents that you define. Your app manages all changes to the widget, including the information shown and the behavior it invokes. When the customer taps an item, they are taken directly to the right place in the app – it can start an activity, or broadcast the intent.

So, with Fire, you have more ways to attract your customer’s attention and to engage with them.

What Developers are Already Building

Zillow

StubHub

Terraria

The designs for each of the examples above are intentionally different. They’re tailored to that app and it’s customers. Because this is about how you can engage with your customers, it’s important to think through the scenarios that would interest and bring them back to your experience.

Creating and Managing a Carousel Widget

For carousel widget development, you’ll be interacting with the HomeManager to create a widget, update a widget, react to taps, define the empty widget behavior and add numeric badges to your app icon.

Here’s an overview of the code you’ll need to create a widget. Please see more detail in the SDK documentation.

//Instantiate your widget

	GroupedListHeroWidget listWidget = new GroupedListHeroWidget();

//create list entries

ListEntry listEntry = new ListEntry();
listEntry.setVisualStyle(SHOPPING);
listEntry.setPrimaryText("Hello, world!");
listEntry.setPrimaryIcon(ICON_URI);

//add your list entries to a list

List listEntries = new ArrayList();
listEntries.add(listEntry);

//add your list to a group and add the group to the widget

Group group = new Group();
group.setListEntries(listEntries);
listWidget.addGroup(0, group);

//finally, add your widget to the Carousel by replacing the default system widget

private HomeManager mHomeManager;
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  // ... create widget
  mHomeManager = HomeManager.getInstance(this);
  mHomeManager.updateWidget(listWidget);
}

You can then update the content of your app widget at any time. If the widget is in focus when you update it, the new data appears immediately. Otherwise, the new data appears the next time the widget is created. If you are using a list display, you can add, update, or remove items from the list incrementally without forcing a refresh of the entire list. Incremental updates are animated. 

Adding a Numeric Badge

// Pass a value (int) to the HomeManager’s updateNumericBadge method.

mHomeManager.updateNumericBadge(38); //numbers over 99 are shown as 99+

// hide numeric badge by setting value to zero

mHomeManager.updateNumericBadge(0);

Reacting to User Taps

At the time you create an item you can define an intent that gets sent when that item is tapped. You can optionally include extra string data that identifies your item to give the receiving activity the ability to know which item was tapped. Use the item's setContentIntent(HeroWidgetIntent) method to set an intent.

HeroWidgetActivityStarterIntent intent =
  new HeroWidgetActivityStarterIntent(
    FULLY_QUALIFIED_CLASS_NAME,
    EXTRA_STRING_DATA
  );
listEntry.setContentIntent(intent);

If you use a HeroWidgetIntent intent, you need to declare a broadcast receiver in the AndroidManifest.xml. A broadcast receiver registered at runtime does not receiveHeroWidgetIntent intents. (See example Manifest and broadcast handling code)

Using the API Simulator Tool

The Fire Phone SDK includes an API Simulator tool for developers who do not have access to a Fire phone. The API Simulator enables you to test basic app features, such as side panels and home carousel widgets using a regular Android device or emulator.

The API Simulator Tool page explains, step by step, how to configure your app for use with the API Simulator and test your app's use of Peek, Tilt, panels and the home carousel widget on a stock Android device or emulator.

Fire, the first smartphone designed by Amazon, introduces a new technology called Firefly which enables customers to quickly identify printed web and email addresses, phone numbers, QR and bar codes, plus over 100 million items, including movies, TV episodes, songs, and products. Customers simply press and hold the dedicated Firefly button to discover useful information and take action in seconds. 

With the Firefly SDK, developers can build apps that recognize real world objects—music, movies and more—and let customers interact with them. As a developer, you can create more immersive experiences that increase both engagement and the frequency of app use. The Firefly SDK comes with built-in recognizers and databases for products, music, movies, URLs, and websites, as well as built-in actions such as dialing a phone number, looking up an object on Amazon or going to a website. Developers can use the Firefly SDK to take advantage of the built-in recognizers, databases and actions.

A New Way to Engage with Customers

An important success metric for any app is engagement, a measure of how frequently and how long people use your app. You need to find ways to bring customers back day after day. Building a Firefly-enabled app is a new technique you can use to get customers to discover your app, sign up and then to come back frequently.

A Firefly-enabled app delivers actionable options (for example, customers can buy concert tickets for a recognized artist) or supplemental item information (for example, the amount of calories in a drink). Customers then have fast and easy access back to your apps, services and brand when they’re actively engaged and interested.

How Developers are Already Using Firefly

Here are a few examples of how iHeartRadio, StubHub and MyFitnessPal have made use of Firefly to give their apps greater exposure to both new and returning customers. All of these examples start when the customer activates Firefly. They do this by pushing and holding the Firefly button on the left side of Fire. Once an item is identified, a list of actions showing the Firefly-enabled apps is offered.

iHeartRadio

iHeartRadio enables customers to listen to live radio stations, create their own artist or song-based custom station from a catalog of more than 19 million free songs, or tune in to thousands of shows and personalities on demand for free. When paired with Firefly, the customer can identify a song with one button press and then directly launch iHeartRadio to create their own station based on that artist.

The team at iHeartRadio utilized the Firefly SDK’s built-in music recognizer and music database to identify songs.  They built their own Firefly action to create iHeartRadio Custom Stations based on the artist and song that Firefly recognizes. “Our integration allows listeners using Firefly to seamlessly discover music in a whole new way,” said Brian Lakamp, President of Digital for Clear Channel/iHeartRadio.  “The Firefly SDK implementation enables music lovers to quickly dive into an iHeartRadio custom experience featuring a variety of songs similar to the one they just heard with just a touch of a button.”

StubHub

StubHub allows fans to buy and sell event tickets. StubHub used the Firefly SDK to let customers identify songs playing in the background and take various actions. “StubHub used the FireFly SDK and the built-in song recognizer, added a Firefly database of concerts and created a ticket purchase action so when customers hear a song in the background they can find out if the band is playing in their area and buy tickets,” said Brendan Weinstein, Android Development Lead at StubHub. “We extended the experience further by using the Dynamic Perspective SDK to bring users right into the concert—letting them look around a stadium or arena to get the feel for the specific seat they are interested in.”

This is a new way for customers to use the StubHub services. When they use Firefly to identify a song or an artist, they have direct access to the Firefly-enabled StubHub app and can be browsing upcoming events before the song is even over.

MyFitnessPal

MyFitnessPal is a free and easy health and fitness system that helps you attain fitness goals. Using Firefly’s built-in product recognizers, the team at MyFitnessPal has added custom actions to give customers nutrition information and to help them easily track their daily calorie intake.

When a customer scans a physical product, barcode or QR code for a food item, MyFitnessPal’s actions and extra information about that food are offered to the customer. They can then tap the item and go directly and add that food item to their diary in the MyFitnessPal app.

Improved discovery of your apps and services

In all of these examples, the app and its services were activated in the context of the customer’s activity. They didn’t need to open an app and navigate to the right screen. Instead, they were able to identify a song, product, barcode, QR code or movie soundtrack, and then launch directly into the app they wanted to use.

Firefly-enabled apps have more options for bringing in new customers and then engaging with them more frequently. Better engagement leads to higher customer satisfaction and ultimately, to better revenue.

@PaulCutsinger

Fire represents a huge leap forward in mobile UX (user experience). As a developer, you’ll want to design the best customer experience possible for this new platform.  To help you achieve that, we’ve outlined the core design principles that will allow you to take advantage of Fire’s unique Dynamic Perspective features. The good news is that if you are an Android developer your app will work on Fire with little or no work, and as you will see, just a few modifications to your app’s UX will let it better take advantage of what the Fire SDK has to offer.

Design Principles

At the core of the Fire UX is the following principle: connect the real world to the digital world, with immersive experiences and rewarding moments. While it’s easy to dive into the deep end and use everything the Dynamic Perspective SDK and Firefly SDK have to offer, the real question you should be asking yourself is: “how will each Fire feature improve the user’s experience?” 

Here are three best practices for designing with the Dynamic Perspective SDK.

Supporting One-Handed Shortcuts with Dynamic Perspective

One way users will interact with the UI elements in Fire-optimized apps is through one-handed shortcuts. You are probably already familiar with incorporating gestures into your UX designs, but what makes Fire unique is the one-handed shortcuts that are driven by a user’s physical interaction with the device. The unique head tracking capability tracks the position of the user’s head relative to the device and when combined with other sensor inputs enables the entire UI to respond to how the device is held, moved and where the user looks.

To help illustrate this, let’s look at the orientation of the device itself.

Here you can see we have the three axes you’ve come to expect in 3D space: x, y and z. By moving the phone along a particular axis the user is able to trigger a gesture. There are three main gestures the user will come to rely on.

Peek

A Peek is triggered when the user subtly rotates the phone around the Y-axis. By slightly angling the device, the perspective of the Dynamic Perspective UI shifts to reveal contextual content.  

Here you can see on the home screen, the device is being held at the default orientation directly facing the user and the top status bar is hidden.

When the user angles the phone to the right, it enables the peek gesture, which will begin to display contextual information such as the top status.

It’s important to keep the following in mind when adding peek experiences to your own app:

• Show things that help the user in the moment. The best way to think of this is mouse-overs on desktop computers that reveal contextual tooltips.
• Reveal secondary information that the user may be looking for, but don’t ‘hide’ primary information on peek.
• Reward close inspection.
• Peek gestures work best in the primary panel.

Tilt

Rotating the phone around the Y-axis will trigger a Tilt. While Peek is a subtle movement, Tilt is at the far end of the movement’s spectrum. Tilt is designed to pull open the left and right panels.

Tilting the phone to the far right on the home screen you will pull up the Left panel. Left panels are typically used for menus and navigation, such as in the below example from the Fire home screen:

For many, this will represent a totally new way of interacting with a digital device and its intention is to invoke a sense of playfulness and delight for the user. In addition to the left panel, there is a right panel, which we’ll talk about more in the next section. You can use a tilt gesture in the opposite direction, moving the right side of the phone towards you, to pull up the right panel. These gestures become intuitive for users since they are facsimiles of how we would interact with physical objects in the real world.

While it’s important to be playful in your design, it’s critical that you don’t make the user work too hard to understand your app’s UX. The key goal is to make the primary UI clean and visually easy to scan by distilling it down to only the essential information.

Working with Fire’s Panels

Fire apps consist of three different panels that help tie the entire experience together for the user. These are the Left Panel, Primary Panel and Right Panel. Let’s take a look at each one and how they work.

Primary Panel

The primary panel is the main application space where most of the action takes place. Here you can see in the Maps app that we are presented with a standard Android View that displays the main UI of the App.

Left Panel

As we discussed in the previous section, the left panel contains quick navigation, refinement controls, sort controls, and other contextual controls. User actions on this panel change the view in the primary panel.

The left panel should contain your app’s actions that are not key to the primary interaction of the app. Core UX should always be contained within the primary panel.

Right Panel

The right panel helps users discover new things or perform essential tasks more quickly without leaving the current context.

The right panel is always contextual whereas the left panel is constant throughout the app. This means that the right panel can also be used for quick summaries, actions tied to what is being displayed on the primary view, or additional shortcut actions that wouldn’t make sense to be exposed in the left panel. The right panel is a good place to positively surprise the user with information that is delightful in the moment, but which they didn’t know to expect. For example, the Amazon MP3 app surfaces song lyrics in the right panel.

By taking advantage of these panels, you’ll also be integrated into the system-wide gesture events. A great place to start is by going through the phone’s default apps such as Email, Maps, Messaging and even the Silk Browser to see how they are setup.

Designing for the Home Carousel

The next important thing to also consider is how your app will look on the home screen carousel. Each app is represented in the carousel with two parts—an icon on top and a widget below the icon.

In the image above, the highlighted red area is your app icon and the area highlighted in green is the widget area.  The widget allows you to expose content without needing the user to launch the app. Text and images can be presented in a grid or list.

The widget communicates with your app using an intent. When the user taps an item in the grid or list, the intent you defined for the item is sent. If you do not provide a widget for your app, the system displays a default widget that shows “Customers Also Bought” content related to your app.

Be creative with this space and use it to drive user engagement.  You could use it to help users quickly launch your app.  Or, use the space to expose a summary of past activity the user may be searching for again.

Today in Seattle, Amazon founder Jeff Bezos unveiled Fire, the first phone designed by Amazon. Fire is the first and only smartphone with Dynamic Perspective and Firefly. Dynamic Perspective is an entirely new technology that responds to the way a customer holds, views and moves the phone. For example, Zillow is using the Dynamic Perspective SDK to create the ability to zoom in on pictures within their app by just moving the phone closer to the user. The revolutionary Firefly technology already recognizes movies, music and more and with the Firefly SDK developers can extend the use of the Firefly button to enable new actions their users can take based on what they can identify. As a developer, these new technologies enable you to create more immersive experiences in your apps and games that increase user engagement.

The Fire SDKs are available now, and make it easy for developers to take advantage of these features in their apps. These SDKs were designed to offer developers power and flexibility with pre-built controls, low level APIs, and complete UI frameworks. You can download both SDKs here.

How Developers Are Using Dynamic Perspective

Fire apps are built with the same familiar Android development environment you are used to. Fire provides a powerful set of hardware to bring your apps alive. With 2 gigabytes of RAM, a powerful Qualcomm Snapdragon 800 Quad-core 2.2 GHz CPU and an Adreno 330 GPU, Fire will support the high performance game experiences customers crave. For detailed technical specifications of Fire, click here.

Zillow used the Dynamic Perspective SDK to integrate real-time information into their app’s user experience. In the Zillow app for Fire, customers can view new listings or nearby homes for sale and rent, right on the Fire carousel without having to open the Zillow app. In addition, Zillow brought a new photo experience to the device so users can use their head to zoom in on a bedroom or peek to see what's around the kitchen corner. “Real estate shopping is an inherently mobile experience so any chance we have to bring listings or new information to a home shopper while they're out on the go is a great thing,” said Jeremy Waxman, Vice President of Marketing and Mobile, Zillow. “Photos are incredibly impactful for home shoppers—it is the most common activity for users of our app. We are thrilled to be able to go one step beyond static images and offer our users the opportunity to zoom in on the photos and then peek around the room with the Dynamic Perspective SDK.”

Ezone.com, the creators of Snowspin and Crazy Snowboard, used the Dynamic Perspective SDK to allow a customer to navigate the endless runner game with just their head—no tapping on the screen necessary. Using head and hand movements, users can control direction and speed. Users can interact with games in a more immersive way – without their hands getting in the way of game play. Additionally, Ezone.com created a special flip jump in Snowspin currently exclusive to Fire customers with just a flick up of the head. “Porting our existing Android versions of Snow Spin and Crazy Snowboard to Fire couldn’t have been easier, and we were able to add new innovative game moves such as a double backflip with just the flick of your head, enabling even higher scores,” said Simon Edis, CEO of Ezone.com. “The Amazon team had all the tools ready to go, making it super easy for us to just drop them in our games and publish.”

CrowdStar used the Dynamic Perspective SDK to create the ability for Covet Fashion users to select their favorite fashion choices for their model. Using zoom and tilt, players can see details of outfits to vote on looks. “Dynamic Perspective is so innovative we’ve just begun to figure out how to take advantage of all the technology has to offer. The simplicity of the user interface and design around a one handed experience will really allow us full creativity as we look ahead in our portfolio of apps and games,” said Jefferey Tseng, CEO of Crowdstar. “Dynamic Perspective has unlocked capabilities we’ve always wanted to create in our game—incorporating zoom and pan in an incredibly natural way without having to touch the screen, is the first example.”

Firefly – Experiencing the World around You

Firefly understands your surroundings, instantly helping you to learn more, discover new things, and take action on the world around you. It can scan physical objects, identify them, and obtain related information about them. Everything from book covers, album covers, bar codes, QR codes, movies, television shows, songs and more. Developers can use the Firefly API to supplement item identification or build actionable options for customers after an item is recognized. For example, iHeartRadio used the Firefly SDK’s built-in music recognizer and music database to identify a song playing. Then they built their own Firefly action to create a station based on the song Firefly recognized.

Go beyond Touch with Shortcut Gestures

Because phones are often used with only one hand, Fire also offers one-handed shortcuts that go above and beyond touch. These shortcut gestures allow you to simply angle the device and “peek” into additional information that your apps can display on screen. For example, customer ratings in the Amazon Appstore instantly appear over each app’s icon when the device is tilted. Navigation is enhanced with gestures: moving back is as simple as flicking up on the screen with a finger, while tilting the device in either direction brings up two additional panels for navigation and contextual information. Gestures can even be integrated inside your games so that users can experience the game in a more intuitive way. Imagine moving a character on screen simply by titling the device instead of having to cover what’s on the screen with your finger.

Creating Multi-Dimensional Experiences inside Your Apps with the new SDKs

Fire enables new ways of interacting with your phone by simply rotating the device around X, Y and Z axes. These gestures were designed to be used with only a single hand, a common scenario when using a phone. We’ve created a framework that integrates directly with these gestures and Fire’s new sensors, making it a simple process to integrate within your own apps.

Fire SDKs and APIs

The underlying technology for Dynamic Perspective and Firefly is sophisticated, but Amazon makes it simple for developers to harness their capabilities. See a full breakdown of the SDKs and their contents here.

Dynamic Perspective SDK

The Dynamic Perspective SDK includes a series of APIs and Controls to help developers create peek, tilt and zoom capabilities within their app based on customer head movements, create multi-dimensional game play, or provide quick navigation menus by tilting the device to the left or right. These experiences are created through a variety of visual effects including adding shadows, depth and tracking head and motion gestures. For example, you could create an app that allows you to peek at how many pages are left in the book you are reading, or browse your apps as if you were flipping through a physical file drawer. Flat cartoonish icons and graphics could be replaced with realistic visuals that use lighting, shadows and motion to create an experience you would want to show off at every opportunity.

Firefly SDK

With the Firefly SDK, developers can build apps that recognize real world objects—music, movies and more—and let customers interact with them. As a developer you can create more immersive experiences that increase both engagement and the frequency of app use. The Firefly SDK comes with built-in recognizers and databases for products, music, movies, URLs, and websites, as well as built-in actions such as dialing a phone number, looking up an object on Amazon or going to a website. Developers can use the Firefly SDK to take advantage of the built-in recognizers, databases and actions.

Fire is Android Compatible

Fire is based on Fire OS so if an app runs on Android it can run on Fire with little to no work. For a developer who just wants to get started with Fire they can do a simple port, or they can use the Fire SDKs to easily integrate UI features such as shadows or hovering images within the app or game, or creating left and right panels based on Fire’s three-panel UI design.

Fire uses the same familiar Android development environment, and while Android Studio is fully supported IDE, you can also use Eclipse and other IDEs. Android Studio Gradle support is also supported for builds. An API simulator for the Side Panels and Carousel is included to test code on stock Android emulators and devices without needing a physical Fire device.

We know that many Android apps and games are built with various technologies so the Fire SDK includes support for those as well. Unity, HTML5 and C++ are all supported. For additional details on using third-party frameworks click here.

By optimizing your apps for Fire, you have the opportunity to create compelling experiences that combine realistic visuals, with both depth and perspective allowing customers to use their smartphone in ways never done before. Starting today we are updating Appstore Developer Select offerings, Amazon Mobile Ads API, and Amazon Testing Service with special Fire incentives.

Amazon Developer Select: Amazon will offer 500,000 Amazon Coins ($5,000 value) for each of your qualifying paid apps or apps with in-app purchasing that meet the additional program requirements for Fire Phone. You can create campaigns via the Promotions Console to give these Coins away to consumers purchasing any of your paid apps or in-app items. For more details on the Amazon Developer Select program for Fire click here.

Amazon Mobile Ads API: Developers earn $6 for every thousand interstitial ads displayed across any supported device in August and September (up to one million impressions per app per month) when they distribute their apps on Fire phones and send the first ad request from a qualified app. For more details on the Amazon Mobile Ad Network Interstitial CPM Offer promotion click here.

Amazon App Testing Service: We have also expanded our testing tool to Fire. Developers can now test their Fire apps before submitting them to the Amazon Appstore. Developers simply drag and drop an app and most will receive feedback about their app’s compatibility within 90 seconds. Additionally, registered developers have access to additional Fire test results that check the app’s experience. These tests enable developers to see how an app looks and performs on an actual device sitting in an Amazon device lab.

With the launch of Fire, Amazon now offers a complete device and apps ecosystem spanning across tablet, phone and TV. Customers pay for your apps once and interact with the experiences you create across all their screens. As a developer, you only need to submit your app once and with few changes make it available to your customers across all Amazon devices. Now is the time to submit your apps and games!
