Step 2: Add App Information

On the App Information tab, you upload your Android binary files (AAB or APK), indicate which devices your app supports, and more. For more conceptual topics related to binary files, see the following:

• Preparing Your Binary File: Provides information about preparing your binary file and the code wrapper that Amazon uses with your app, as well as size limitations and other details.
• Device Filtering and Compatibility: Explains how attributes in your manifest determine the devices your binary supports.

App Information fields

The following table describes the fields on the App Information tab for Android apps.

App Information tab fields

Field	Description
Add App Bundles or APK Files	Upload an Android App Bundle (AAB) or an APK file. If submitting an APK and you didn't use Android Studio to build your signed APK, you might need to zipalign your file. You can upload multiple binary files by dropping one file at a time into the box. When you add a binary file, you can see its details by clicking the information icon . These details include the version code, version name, file size, package name, minimum SDK version, features, libraries, permissions, localizations, supported screens, compatible screens, OpenGL details, and native platforms. For example: These details determine what devices are supported by your binary file (filtering is explained in Device Filtering and Compatibility). Tip: The package name in your app must be unique, and it shouldn't include amazon in the name. If you use the same package name as another app, you will get an error when uploading the binary. The versionCode must be unique as well (and not the same as the versionCode in a previous binary you uploaded). After you upload a binary, the file receives an alias, for example, "APK1". You can rename the alias as desired. The custom alias is used internally and not be seen by customers. See Preparing Your Binary File and Update a Published App for more details related to binary files.
Allow Amazon to Apply DRM?	DRM (digital rights management) protects your app from unauthorized use. Without DRM, your app can be used without restrictions by any user. Note: If your app uses the Appstore SDK, you won't see this option. You can add DRM to your app by using the DRM API, which is part of the Appstore SDK. For more information, see DRM Overview. If your app isn't using the Appstore SDK, Amazon can automatically add DRM functionality to your app. Select Yes to allow Amazon to add DRM to your app. Select No if you do not want Amazon to add DRM to your app. If you have multiple binary files, your selected DRM setting applies to all of your app's binaries. If you have previously uploaded binary files and are adding a new binary with different DRM settings, you must replace the previous binary files if you want them to receive the updated DRM settings. Otherwise, your previous binary files retain the same DRM settings as before. For more information about automatically-applied Amazon DRM, see About DRM.
App title	A title for your app, used only in the Developer Console. You define the title users see in the Appstore and on devices on the Description tab, in the Display title field.
App SKU	App Stock Keeping Unit string. The SKU is a string unique (which you define based on your choosing) for your app. For example: com.amazon.example.myapp.v1). The SKU becomes the ID for your app for your own tracking purposes. Amazon does not require or use the app SKU. However, adding a unique identifier can help you keep track of multiple versions of your app. Note that SKUs are case-sensitive and have a max length of 150 characters. They can contain the characters a-z, A-Z, 0-9, underscores, periods, and dashes.
App Submission API keys	After you save your app, you will see App Submission API keys. These keys allow you to manage your app information programmatically through the App Submission API.
App category	A category for your app based on your best judgment. Categories are used primarily for setting up the Amazon Appstore browse tree and for grouping together the Similar, Related, and Recommended app suggestions for users. The top-level categories are the same across Fire tablets, Fire TV, and non-Amazon Android devices, though some subcategories might not be available for Fire TV apps. If you don't see an obvious category for your app, choose the closest fit.
Release notes	This field appears only if you are submitting a new version of an existing app. Describe the changes you've made in this update. On your app's Appstore details page, release notes appear in a "Latest updates" section. On Fire TV devices, users (who have installed the app) see the release notes in the Notifications section in Settings. On Fire tablets, users see the updates in the notifications pull-down menu at the top. Note: Only the account administrator and marketer roles can update this field. For more details, see Permissions by role.
Customer support contact	If selected, your default support information (found under Settings > Company Profile in the Developer Console) is used for the Customer support email address, Customer support phone, and Customer support website fields.
Customer support email address	An email address where customers can contact you.
Customer support phone	A phone number where customers can contact you.
Customer support website	The URL for your app’s support website.

Public key and PEM file

In the upper-right area of the tab, there is a link for a Public Key. This public key, which is unique per app, establishes a secure communication channel between the Amazon Appstore and your app. When you generate the public key from the Developer Console, Amazon generates a corresponding private key. These public and private keys form a key pair to sign license responses. Through this key pairing, you ensure that the users who install your app are authorized.

The public key is stored in a PEM file. If your app uses the Appstore SDK or the Appstore SDK plugin for Unity for In-App Purchasing (IAP) or DRM, you must add the PEM file to your project. To configure your app with the public key:

1. Click Public Key.

2. In the Public Key dialog box that appears, click the AppstoreAuthenticationKey.pem link to download the PEM file.

   

3. Copy the AppstoreAuthenticationKey.pem file.

4. Follow the instructions for your project type.

   Android project instructions

   1. Paste the PEM file into the app/src/main/assets folder of your Android Studio project.
   2. In the Project view, the assets folder is usually in app/src/main/assets. If your app doesn't have an assets folder, you must create one. Then drag your PEM file into it.

   Unity project instructions

   1. In the Assets folder of your project, create a new folder named StreamingAssets.
   2. Paste the PEM file in your Assets/StreamingAssets folder.

For more details, see Configure Appstore SDK with your public key or Configure Unity App with Public Key.

Appstore certificate hashes

Certificate information, which includes the SHA-1, MD5, and SHA-256 hashes, is available from a link in the upper-right area of the tab. As part of the ingestion process, Amazon removes your developer signature and applies an Amazon signature. This signature is unique to you, does not change, and is the same for all apps in your account. For more details, see Amazon App Signatures.

Update an existing app

If you're updating an existing app, see Update a Published App. When you make the update, you have the option of replacing the existing binary file and retaining the same Device Support selections, or removing the previous binary file and re-selecting your Device Support details.

Adjust device support for your app

After you upload your app's binary file , the number of supported devices appears in the Uploaded Files section.

To manage which devices your binary supports, select Edit next to the number of supported devices. In the Device Support overlay, devices with an 'X' next to their name are unsupported. Unsupported devices are determined by the attributes in your manifest and the countries you target in the Availability & Pricing tab.

If you see a device marked unsupported, find out why by moving your mouse over the help icon next to the device name in the Device Support dialog box, as shown in the following image.

If necessary, you can manually remove support for devices that have known compatibility issues. The supported devices are grouped into four categories:

• Amazon Fire tablets: Shows the Fire tablet support for your app. See the Tablet Device Specifications for more details. By default, device support for your uploaded binary is turned on for all Amazon Fire tablet devices, and for all non-Amazon Android devices.

• Amazon Fire TV devices: Shows the Fire TV device support for your app. For details on Fire TV device names, see Fire TV naming conventions; for specifications, see Device Specifications for Fire TV.

• Non-Amazon Android devices: Shows Android devices on which your app could be installed through the Amazon Appstore for Android app. The Amazon Appstore supports non-Amazon devices running Android 5.0 and above. This option provides additional distribution avenues for your app (and is especially helpful if your app is only available in the Amazon Appstore, not on Google Play). Within this non-Amazon Android devices grouping, devices are sorted into three groups: Supported (compatible), Excluded (manually de-selected), and Unsupported (incompatible based on your manifest settings).

• Windows devices (Not an option for web apps): Allows your app to be distributed on Windows 11 devices. For details on targeting Windows devices, see Target Windows Devices.

To adjust which devices are supported by your app, click Edit device support and update the devices indicated. Toggle device support on (green) or off (gray) as appropriate. Use the tabs at the top of the dialog to move between categories.

For example, if you're uploading a streaming media app designed for Fire TV devices, click Edit device support on the Amazon Fire TV devices row and select the appropriate device support options on the Amazon Fire TV tab:

For additional information about supported devices for your app, see the following:

• Troubleshooting Android Manifest and Device Filtering
• Device Filtering and Compatibility
• Supported Filters on the Amazon Appstore.

For non-Amazon devices, at the bottom of the Device Support dialog, there's an option for All other Android devices. The Non-Amazon Android devices can be toggled on or off as a whole, or you can manually adjust device support. This setting allows your app to be distributed to any other Android devices, including future compatible Android devices. New devices are added regularly based on device popularity. Through manifest filtering, the Appstore automatically determines the device's compatibility.

If you turn off "All other Android devices," you change your compatibility strategy from using a deny-list to using an allow-list for non-Amazon devices. In other words, your app won't be compatible by default on those devices; instead, you'll need to manually select which third-party devices your app will support.

To add an additional binary for the same app, see the section, Add multiple binaries for the same app.

Devices supporting only 64-bit apps

Some devices no longer support 32-bit apps, including any 32-bit apps currently available on Amazon Appstore. Customers attempting to download a 32-bit app on one of these devices will receive a notification alerting them that the app is not compatible with system requirements.

To make your app available to customers using one of these devices, add 64-bit (arm64-v8a) support to your app and submit an update using the Amazon Developer Console. Do not remove support for 32-bit (armeabi-v7a) while building your app, as it may impact current Amazon device selection.

Add multiple binaries for the same app

The Amazon Appstore supports uploading multiple binaries for both AAB and APK files. For APKs, more conceptual details are explained in Multiple APKs for the Same Application Listing.

When uploading multiple binaries, make sure each file has the same package name in the manifest; however, each individual binary should have a unique versionCode in your Gradle build file.

When your app is available on the Appstore, each device has one APK associated with it. During app submission, when you add multiple binary files, you have to remove support for devices from your first binary that you want to be available for the additional binary files. The following step-by-step instructions and screenshots clarify this selection process.

To upload multiple binary files:

1. If you haven't already uploaded your first binary file, upload it by dragging the file into the App Bundles or APK Files box.

2. For the first binary you uploaded, next to "Supported Devices," click Edit and remove support for devices that you plan to target with your second binary.

   For example, suppose you have two APKs for your Fire TV app — "APK1" and "APK2". With APK1, you want to target all Fire TV devices except Fire TV (3^rd Gen). For APK1, click Edit next to "Supported Devices" in the APK File section. In the Device Support dialog box that appears, clear the check box next to "Fire TV (3^rd Gen)." This makes Fire TV (3^rd Gen) available for APK2 to target. If you don't remove the device support from the first APK, you won't be able to target it with the second APK.

   

   Note that if you're updating an existing binary file, when you clear the checkbox next to some supported devices, you might see a "Reduced device support" warning. This warning lets you know that you're shrinking the number of supported devices for your app. Customers who previously installed your app on those devices (now unsupported by this binary) won't get the update. (You can read more in Warning: Reduced device support.) Because you're uploading multiple binary files, you can disregard this notice. After you upload another binary and target these devices removed from your first binary file, the warning is no longer be applicable.

3. (Optional) Give your binary file a recognizable alias to distinguish it from the next binary you upload.

4. Drag another binary file into the App Bundles or APK Files box. Optionally, change the alias for the new file you upload to distinguish it from the first binary file.

   When you drag another binary file into the App Information tab, the devices supported by the first binary are unavailable for the second binary file — because two binary files can't be installed on the same device. Under the greyed-out devices, you should see the phrase "Targeted by another APK in the current version." ("Targeted" just means that you selected support for the device with your app.) Remember this rule: Multiple APKs cannot be installed on the same device. With the second binary file, you can select support for devices not already selected by the first binary.

   Continuing with our previous example, suppose you upload "APK2" and want Fire TV (3^rd Gen) to support this APK. You already cleared support for this device with the previous APK, so it should now be selectable with this second APK.

   

   With multiple binary files, the Amazon Appstore does not automatically assign the binary based on the API level or versionCode(unlike with Google Play). You must manually select the supported devices when uploading multiple binary files.

5. When finished, click Save.

   You can add more than two binary files per app. Continue adding as many binary files as desired.

Troubleshooting common errors

This section provides troubleshooting information related to binary file submissions on the App Information tab.

Error: Duplicate package name

When uploading a binary file, you see one of the following errors:

• Failed to upload APK. The package name of the uploaded APK, com.amazon.android.yourapp, is already in use by an app owned by a different developer. Please contact us for more information.
• Failed to upload App Bundle. The package name of the uploaded bundle, com.amazon.android.yourapp, is already in use by an app owned by a different developer. Please contact us for more information.

First, check to make sure that you have not uploaded this binary file on another Amazon developer account as either an app submission or Live App Test. If you haven't uploaded this same file under another account, submit a support case reporting the issue and noting the package name. To submit a support case, sign in to the Developer Console, click the ? in the upper-right corner, and click Contact Us.

Note that when using development environments such as Unity or pre-existing manifest files, it's possible that your app's package name will have a placeholder value that should be changed prior to submission. The package name of your binary file must be unique to the app you are publishing and is usually in the format of com.companyname.appname.

If you have an association with a developer or publishing company that might have uploaded your app for Live App Testing, contact your development partner to confirm that they have not submitted your binary file on their account. If they have, ask them to end the current Live App Test. Then contact Amazon with the package name to resolve the issue.

Warning: Reduced device support

When adjusting device support for a binary file, you see a warning that says the following:

• Device support has been reduced from the previous version. Some existing customers will not be able to upgrade. To resolve manifest conflicts, Amazon recommends editing the manifest to retain your current device support.

This message means that, with your newly uploaded binary file, you have introduced new attributes in your manifest or build.gradle file that shrink the number of compatible devices. Most commonly, you might have incremented the API level, which reduces the number of devices that can support the update. As such, the Appstore is warning you that some devices might not be able to install this update.

For example, suppose you publish an APK with manifest attributes that require at minimum API level 19, and customers with a device supporting API level 19 (but not support for any level greater) install the app. Later, you update the app with new features or permissions requiring APK level 22 as a minimum. This new update will be incompatible with the previous version of the app the customer (with API level 19) installed. As a result, the customer will not see that an update is available.

Target device not available

When uploading a new binary file, you see a message that says a particular device is not supported. The message might one of the following:

• Your App Bundle manifest requires capabilities not present on this device.
  android:minSdkVersion = '22'; device requires '15'
• Your APK manifest requires capabilities not present on this device.
  android:minSdkVersion = '22'; device requires '15'

To see the reason the device isn't supported, move your mouse over the help icon next to the device name in the Device Support dialog box. See Adjust device support for your app above for more details. The incompatibility could be due to the API level, OpenGL compression format, CPU, screen size and density, device features, or even other factors about your app such as lack of availability in the geographic locale.

Targeted by another binary in the current version

If you're uploading multiple binaries, the device might already be supported by another binary file. If so, when you move your mouse over the unsupported device, it says:

• Targeted by another binary in the current version.

Multiple binaries cannot support the same device. You must edit the device support for one binary file so that you can select support for the device with the other binary. See Add multiple binaries for the same app for step-by-step details. See Multiple APKs for the Same Application Listing for a more conceptual background.

Upload app bundles

You can submit Android App Bundle  files to the Amazon Appstore, without the need to create separate APKs. The Appstore uses the bundletool to convert the app bundle files into a single universal APK that can be downloaded and installed across client devices. There won't be any change in customer experience or app file size.

For details on how to create, test, and submit app bundles, see App Bundles.
