Adding advertising to your apps is easy. Integrating ads doesn’t require a major redesign of your app and has minimal impact on your app’s functionality. It is as simple as making space for the ad on the screen. The Amazon Mobile Ads API (Beta) enables you to display high-quality ads provided from the Amazon Mobile Ad Network in a matter of minutes. This article explains how to place ads into an existing app using the Amazon Mobile Ads API.
First and foremost, submit your payment information through the Payment Information Page and your tax information through the Tax Identity Interview. You can skip this step if you have already submitted this information through the Amazon Mobile App Distribution Portal. This is required to receive ads.
The Amazon Mobile Ads API utilizes a unique Application Key to identify and interact with an app. Every app will have its own Application Key. If your app is already on the Distribution Portal, you can find your Application Key on the app’s detail page. Otherwise, create a new app and fill in the “App title” and “Category” fields. Locate the Application Key value and set that aside. We will use that later to register with the Amazon Mobile Ad Network.
Next, you will need to add the Amazon Mobile Ads API to your project. For the purposes of this example, we will use Eclipse.
Download the Amazon Mobile Ads API (Beta) from here (this should link to our API landing page which has the file for download and the legal verbiage) and unzip it locally.
Add the JAR to Your Project
Modify the build path of your project and add the amazon-ads-<x.y.z>.jar found in the zip under the /Ads/lib folder.
This step is required to set up ads through the xml layout. Copy the amazon_ads_attr.xml file from the zip located in /Ads/res/values/ into your project’s res/values/ folder.
The Amazon Mobile Apps API requires the following permissions and activities:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<activity android:name="com.amazon.device.ads.MraidBrowser" android:configChanges="keyboardHidden|orientation"/>
<activity android:name="com.amazon.device.ads.VideoActionHandler" android:configChanges="keyboardHidden|orientation|screenSize"/>
Now that the project is set up to use the Amazon Mobile Ads API, the next step is to add an ad to the application layout.
Now we can call the Amazon Mobile Ads API to load ads.
Time to put that Application Key to work. In your activities onCreate, call the AdRegistration method to register your app and then call the Amazon Mobile Ads API to load an ad. Please note that you may only use an Application Key to display ads on the specific app for which it was issued.
//Register App with the Ad Network
//Load ad on to AdLayout
adview = (AdLayout)findViewById(R.id.adview);
Submit your app to Amazon to display ads to your U.S. users and follow the attribution guidelines set forth here. The Amazon Mobile Ads API can also be used with apps that are distributed through any Android stores. Apps that use the Amazon Mobile Ads API may be distributed through any Android store as long as they are distributed through Amazon.
Your app is ready to display high-quality ads from the Amazon Mobile Ad Network. This is the simplest of configurations but the Amazon Mobile Ads API has several features for customizing your ad layout, ad targeting, error handling, debugging, and more.

Amazon will be sending tens of millions of dollars to Kindle Fire users; money that can only be used to buy apps for Kindle Fire. If you don’t want to miss a minute of that action, make sure your app is available for sale on Kindle Fire devices, or submit a Kindle Fire compatible app by April 25 for the best chance of getting in the Amazon Appstore in time. (If you submit after 4/25, your app will still be eligible, but may not make the start of the gold rush.)
In May, Amazon is introducing Amazon Coins, a new virtual currency that customers can use to pay for apps and most in-app-purchase items. To help promote this new currency, Amazon is going to give away tens of millions of dollars in Amazon Coins to Kindle Fire users. This money will be burning a proverbial hole in customers’ pockets as they look for places to spend it. We’d like your app to be one of the tempting places to spend that currency.
U.S. customers will be able to spend Amazon Coins on apps and most in-app purchase items. (Subscriptions cannot be purchased with Amazon Coins.) Each Amazon Coin is worth 1-cent, so a $2.99 app will cost 299 coins. The way you get paid doesn’t change if the customer pays with Amazon Coins or a credit card; you get paid in real U.S. Dollars, at the same 70% revenue share you normally receive.
If your app is available for sale on a Kindle Fire device, then you’re done; nothing else to do. It doesn’t matter if your app is also available on other Android devices, as long as it is available on a Kindle Fire device, it is eligible.
If you already have an app in the Amazon Appstore for Android, it’s fairly easy to make it available for Kindle Fire Tablets. Take a look at the Kindle Fire Development Best Practices here for hints on how to make your app shine on Kindle Fire, and then re-submit your app with the appropriate Kindle Fire devices selected on the Binary Files tab (see below).
Please submit your apps by April 25th to give us the best chance of having enough time to review them and get them in the Amazon Appstore before tens of millions of dollars in Amazon Coins arrive in customers’ accounts.
If you don’t have an app in the Amazon Appstore, don’t worry. You may be able to submit your existing Android app without too much work. If you use Google Play Services for In-App Billing, Messaging, or Maps, you will need to replace them with the corresponding Amazon APIs before submitting. These APIs are:

Amazon Coins is launching in May. Tens of millions of dollars of Amazon Coins will be given to customers for free to spend on Kindle Fire apps, games, and in-app items. If your apps are already on Kindle Fire, then no action is required. If you have new apps or games ready, submit them by April 25th to ensure we have time to review your apps before millions of dollars in Amazon Coins arrive in customers' accounts.

Following the success of the In-App Purchasing API, we are pleased to introduce a new monetization option for app developers, the Amazon Mobile Ads API. Now, whether you monetize through paid apps, in-app purchases, or mobile advertising, Amazon offers a solution to help grow your business.
The Amazon Mobile Ads API is an in-app display advertising API, which offers:
The Amazon Mobile Ads API serves ads to U.S. users, and works with mobile apps on Kindle Fire, Kindle Fire HD, and Android phones and tablets. Apps that use the Amazon Mobile Ads API may be distributed through any Android platform as long as they are available for download from Amazon as well.
Developers who participated in the private beta program reported an increase in ad revenue, especially on their Kindle Fire optimized apps, after integrating with the Amazon Mobile Ads API.
“We switched to Amazon from another major ad network and have seen revenue lift of 200%. Now, I call Amazon first, then another network, so my overall revenue increased 250%. The results from Amazon have greatly exceeded our expectations.”
-- James Farrier, Founder (Simple-List Free)
“Our experience with Amazon has been nothing but great. We were able to integrate in 15 minutes with the easy to follow API and documentation. We’re excited about the eCPM and fill rate so far. Our users have been happy with the quality and relevance of ads they are seeing.”
-- Steve Boymel, Co-Founder of Farlex (Dictionary)
“We decided to try Amazon's ads because our overall revenue and eCPM was low on tablets when we were using another network. We initially integrated the Amazon Mobile Ads API in one of our apps distributed through Amazon since the majority of our users there are on Kindle Fire devices. Our effort has paid off! We saw eCPM jump 300% and our revenue doubled even though fill rate was lower at the beginning. Now we have the Mobile Ads API integrated in all our free apps distributed through Amazon.”
-- Anatoly Lubarsky, Founder of x2line.com (Baby Adopter)
At Amazon, we love apps—so much, in fact, that we develop many mobile apps ourselves, and even have an in-house game studio. On the heels of the recent press from the Localytics report that the leading Android tablet is Kindle Fire (with 33% of market segment share worldwide and more than half in the US), we wanted to post some best practices for using in-app purchasing from our colleagues at Amazon Game Studios—developers of the recently released game Air Patriots.
This post is from Ernie Ramirez, Executive Producer, Amazon Game Studios:
Air Patriots is a new type of tower defense game where players control a squadron of airplanes by drawing the attack paths they use to engage the enemy. Air Patriots launched on November 1, 2012, on Amazon, iOS, and Google Play. Although our monetization on Amazon has been great (generating 73% higher ARPU than iOS, and both stores generated similar total revenue), we had some key learning during our initial launch. For example, our focus groups indicated that the two things customers would like to buy were more maps & more planes, in that order. This meshed with our goal of providing Air Patriots customers “big value” for in-app purchases. We reasoned that we would emphasize additional maps for purchase because it would give customers significantly more play time and provide a feel that they paid for something really big and worthwhile.
We originally structured Air Patriots to provide gamers 2 of the 7 maps for free, with the remaining 5 requiring an in-app purchase. Additional airplanes were available using the in-game “soft currency” (gears). As a test, we also included a fully-loaded helicopter available via in-app purchase. It turns out that, after launch, the helicopter was our top-selling individual in-app item, and customers were responding negatively to the 5 additional maps. We received feedback that customers were feeling arbitrarily blocked from progressing in the game, which was not our intention!
We updated the game—reduced prices of our in-app items, increased the amount of maps available with the in-game “soft currency” and offered more planes for sale with in-app purchasing. Customers responded immediately—the sales picked up and we started receiving reviews describing the game as “so darn addicting—pay a couple bucks for different planes. So cool!”
To recap, here are a few things that we recommend to other mobile game developers:
We discovered that selling main-line game content like levels or expansion packs via in-app purchasing in a freemium game risks making customers feel arbitrarily blocked and frustrated
Customers prefer to buy things that improve their performance and/or give them new abilities to make them feel “stronger”

In a recent study of more than 500 games that utilize in-app purchasing on Amazon, we found that mobile games using Amazon GameCircle’s leaderboards and achievements monetized significantly better than other games.
For the three-month period from November 2012 to January 2013, games using GameCircle produced 38 percent higher conversion rates and 33 percent more in-app orders per paying customer than games that didn’t use GameCircle. Conversion was measured by calculating the percentage of app users that made at least one in-app purchase. Combining the impact of both of these variables, GameCircle-enabled games earned 83 percent more average revenue per user (ARPU) than non-GameCircle games.
The free-to-play (or freemium) model, where consumers download and play a game for free, has become one of the most prominent business models in mobile gaming today. However, the biggest challenge for game developers following the freemium model is figuring out how to generate more revenue by converting non-payers into payers and keeping those paying users engaged.
Many of Amazon’s mobile game developers have discovered how GameCircle’s services–Achievements, Leaderboards and Whispersync–have contributed to their success at Amazon. GameCircle lets players connect with other players to compare achievements and compete for higher scores. These social elements get the competitive juices flowing, which may increase a user’s willingness to pay for in-game content, leading to higher conversion rates for developers. “PlayFirst's games on Amazon have performed above and beyond our expectations, and we believe GameCircle has enhanced our ability to connect and engage with Amazon customers, encouraging more play sessions," said Paul Chen, VP of Business Development at PlayFirst.
GameCircle also offers new discovery mechanisms that are an important factor helping drive increased engagement rates. For games that have integrated with GameCircle, players can see their friends, achievements, and leaderboard activity before launching the application, since all of this information is visible right from the user’s game library. Leading games such as Skylanders Cloud Patrol, Diner Dash, and Temple Run 2 have already integrated with GameCircle. The image below showcases how a user’s library is populated with GameCircle meta-data.
This added visibility is a powerful engagement tool. A related study that we conducted in January 2013 found that, on average, games using GameCircle over-indexed on the number of player sessions (defined by the number of times users opened the applications on their device) by 32 percent when compared to the average for the entire games category. For freemium games that monetize by selling in-game content, this enhanced level of engagement is critical to expanding customer lifetime values. "We see superior engagement, retention and monetization from players who download our games from Amazon. The GameCircle integration is helping us achieve 40 percent better per user monetization rates compared to non-Amazon players," said Sean Thompson, Vice President of Mobile Deluxe.
For you, GameCircle represents another opportunity to provide gamers with a more seamless and entertaining in-game experience, which can lead to increased engagement and monetization.

Today we announced the upcoming launch of Amazon Coins, a new virtual currency for U.S. customers to purchase apps, games, and in-app items on Kindle Fire. When Amazon Coins launches in May, we will be giving out tens of millions of dollars worth of Coins to customers to spend on Kindle Fire apps, games, or in-app items.
For customers, it's an easy way to spend money on Kindle Fire apps and games. They'll be able to purchase as they do now, but with the ability to choose to pay with a credit card or using Coins. For you, it's another opportunity to drive traffic, downloads, and increased monetization. Plus, there's no integration required--you'll get paid the same 70% revenue share whether the customer chooses to use Coins or their own money.
To take advantage of this unique opportunity, you only need to do one thing: make sure your new apps and app updates are submitted and approved by April 25th so they'll have the best chance of being available for Coins purchases at the launch of the program (and when we give customers their free Coins).
