How to Detect EdXposed Framework to Protect Android Apps

Last updated December 6, 2023 by Appdome

Learn to Detect EdXposed Framework in Android apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is EdXposed Framework?

EdXposed Framework  is a carryover project that stemmed from the original Xposed rooting framework. EdXposed improves on Xposed by using what is known as a Riru module to inject code into Android’s Zygote process as part of initializing Android. Zygote is a low-level Android OS process that enables shared code across Dalvik and Android Runtime virtual machines. The net result is a more efficient way of Rooting Android, as EdXposed ‘modules’ can work across different versions and different ROMs without any changes. As all changes are made in the memory space, you only need to deactivate the module and reboot to get your original system back.

This combination of EdXposed and Riru modules allows users to install EdXposed Framework on devices running Android 10, Pie, and Oreo.  EdXposed is used by pen testers and hackers to modify the flow of an Android app at runtime, by writing custom modules for hooking into the said Android apps.

Why Detect EdXposed Framework in Android Apps?

The reason for blocking EdXposed by adding Appdome’s Root Detection to any Android app is that while a developer or a pen tester may use EdXposed during the development stages of your app, once the app is complete you can assume that any use of EdXposed is made by a malicious party in order to modify your Android app.

Using EdXposed requires having a rooted Android device, as well as the setting Enable Unknown Sources turned on, as this setting allows attackers to install programs whose source is not an approved store (like custom exposed modules) onto an Android device.

In addition to root detection, you can also add the Detect Unknown Sources  protection, thus further tightening the security of your Android app.

Prerequisites for Using Root Detection:

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

Detect EdXposed Framework on Android apps using Appdome

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

  1. Upload the Mobile App to Appdome.

    1. Upload an app to Appdome’s Mobile App Security Build System

    2. Upload Method: Appdome Console or DEV-API
    3. Android Formats: .apk or .aab
    4. Root Detection Compatible With: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps
  2. Build the feature: Root Detection.

    1. Building Root Detection by using Appdome’s DEV-API:

      1. Create and name the Fusion Set (security template) that will contain the Root Detection feature as shown below:
      2. fusion set that contains Root Detection

        Figure 1: Fusion Set that will contain the Root Detection feature
        Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).

      3. Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Root Detection feature via Appdome Console, to add the Root Detection feature to this Fusion Set.

      4. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below): fusion Set Detail Summary image

        Figure 2: Fusion Set Detail Summary
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Circle CI or other system:
        1. Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
        2. Look for sample APIs in Appdome’s GitHub Repository
    2. Building the Root Detection feature via Appdome Console

      To build the Root Detection protection by using Appdome Console, follow the instructions below.

      1. Where: Inside the Appdome Console, go to Build > Security Tab > OS Integrity section.
      2. How: Check whether is toggled On (enabled), otherwise enable it . The feature Root Detection is enabled by default, as shown below. Toggle (turn ON) Root Detection, as shown below.
        If needed, Customize the Threat Notification to be displayed to the mobile end-user in a standard OS dialog notification when Appdome Detects EdXposed Framework.
        Root Detection option

        Figure 3: Detect EdXposed Framework option
        Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

      3. When you select the Root Detection you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Root Detection

        Fusion Set applied Root Detection

        Figure 4: Fusion Set that displays the newly added Root Detection protection

      4. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Root Detection:
        1. Threat-Events™ OFF > In-App Defense

          If the Threat-Events™ setting is cleared (not selected). Appdome will detect and defend the user and app by enforcing Detect EdXposed Framework.

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

          When this setting is used, Appdome detects if the device has been rooted 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™ for Root Detection Intelligence and Control in Mobile Apps.

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

          When this setting is used, Appdome detects and defends against EdXposed Framework (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence 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 Root Detection Intelligence and Control in Mobile Apps.

      5. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
    Congratulations!  The Root Detection protection is now added to the mobile app
  3. Certify the Root Detection feature in Android Apps

    After building Root Detection, Appdome generates a Certified Secure™ certificate to guarantee that the Root Detection protection has been added and is protecting the app. To verify that the Root Detection protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Root Detection shown in Certificate secure

    Figure 5: Certified Secure™ certificate

    Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Root Detection has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Root Detection and other mobile app security features are in each build of the mobile app

Using Threat-Events™ for EdXposed Framework Intelligence and Control in Android Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when EdXposed Framework is detected.

The following is a code sample for native Android apps, which uses all values in the specification above for Root Detection:


Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.



Using Appdome, there are no development or coding prerequisites to build secured Android Apps by using Root Detection. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
