How to Detect Banned Devices in Android Apps

Last updated December 6, 2023 by Appdome

This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Detect Banned Devices in Android apps.

What are banned devices?

Banned devices are Android mobile devices that are not included in Google Support’s list of publicly launched devices supported for use with Google Play and your apps. Supported devices are devices that have passed the Android Compatibility Program, which defines technical details of the Android platform and provides tools that allow OEMs to ensure that developer applications run on a variety of devices.

Why Detect Banned Devices in Android Apps?

Organizations may have to prevent mobile apps from running on banned devices in order to comply with a specific internal company policy or an external regulation or government mandate. While restricting the device in Google Play may help in limiting the distribution via the standard way, applications can always be side-loaded via tools such as adb or Android Assistant.
Using Appdome’s Banned Devices feature is a ‘defense in depth’ approach implemented deep within the logic of the mobile app itself. Appdome Android Banned Devices prevention detects if the app is running on untrusted or banned devices. Appdome customers can specify mobile device manufacturers and prevent mobile apps from running on these banned devices.
Appdome automatically identifies the manufacturer of the Android device, once the application loads, and enables you to block the app from running on pre-defined unwanted devices.

Prerequisites for Using Appdome's Detect Banned Devices Plugins:

To use Appdome’s mobile app security build system to Detect Banned Devices , you’ll need:

How to Implement Detect Banned Devices in Android Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Detect Banned Devices without an SDK or gateway:

  1. Designate the Mobile App to be protected.

    1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.

    2. Android Formats: .apk or .aab
    3. Detect Banned Devices is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
  2. Select the defense: Detect Banned Devices.

      1. Create and name the Fusion Set (security template) that will contain the Detect Banned Devices feature as shown below:
        fusion set that contains Detect Banned Devices

        Note: The Appdome Platform displays the Mobile Operation Systems supported by each defense in real-time. For more details, see our OS Support Policy KB.

      3. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Detect Banned Devices:
        1. Threat-Events™ OFF > In-App Defense

          If the Threat-Events™ setting is not selected. Appdome will detect and defend the user and app by enforcing Banned Devices.

        2. Threat-Events™ ON > In-App Detection

          When this setting is used, Appdome detects if the app is running on untrusted or banned devices and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing, enforcement, and user notification. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ to Detect Banned DevicesDetect Intelligence and Control in Mobile Apps.

        3. Threat-Events™ ON > In-App Defense

          When this setting is used, Appdome detects and defends against Banned Devices (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Detect Banned DevicesDetect Intelligence and Control in Mobile Apps.

      4. Configure the User Experience Options for Detect Banned Devices:
        With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.
        1. App Compromise Notification: Customize the pop-up or toast Appdome uses to notify the user when a threat is present while using the protected mobile app.
        2. Short message Option. This is available for mobile devices that allow a banner notification for security events.
        3. Localized Message Option. Allows Appdome users to support global languages in security notifications.

          Localized Message
