How to Detect Java and Kotlin Dumps in Android Apps Using AI

Last updated September 10, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Detect Java and Kotlin Dumps in Android apps.

What Are Java and Kotlin dumps?

Java and Kotlin dumps occur when attackers extract objects and classes from an Android app’s runtime environment. By dumping in-memory structures, adversaries can recover business logic, cryptographic keys, or sensitive variables without reverse engineering the APK. These attacks exploit debuggers, instrumentation frameworks, or malware to bypass traditional code protections. Because runtime objects exist only in memory, static analysis and obfuscation are not enough to stop dumps. Detecting and blocking such activity is critical to prevent intellectual property theft, app manipulation, and compliance risks under data protection regulations.

How Appdome Protects Android Apps Against Java and Kotlin Dumps

Appdome’s dynamic Detect Java and Kotlin Dump plugin continuously monitors runtime objects to identify suspicious dump operations. It prevents debuggers, hooking frameworks and memory dumping tools from extracting class structures or sensitive variables from memory. Upon detection, a user will be presented with a pop-up screen stating the attack and that the app will close. Alternatively, mobile developers can leverage Appdome’s Threat-Events framework to create custom UI and UX experiences based on Java and Kotlin Dump detections. 

Prerequisites for Using Appdome's Java and Kotlin Dumps Plugins:

To use Appdome’s mobile app security build system to Detect Java and Kotlin Dumps , you’ll need:

How to Implement Detect Java and Kotlin Dumps in Android Apps Using Appdome

On Appdome, follow these simple steps to create self-defending Android Apps that Detect Java and Kotlin Dumps 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. Java and Kotlin Dumps is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
  2. Select the defense: Java and Kotlin Dumps.

      1. Create and name the Fusion Set (security template) that will contain the Java and Kotlin Dumps feature as shown below:
        fusion set that contains Java and Kotlin Dumps

        Figure 1: Fusion Set that will contain the Java and Kotlin Dumps feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Java and Kotlin Dumps feature to your Fusion Set via the Appdome Console.

      3. When you enable Detect Android Memory Dump you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Java and Kotlin Dumps.

        Fusion Set applied Java and Kotlin Dumps

        Figure 2: Fusion Set that displays the newly added Java and Kotlin Dumps protection
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      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 3: Fusion Set Detail Summary

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:
        1. Refer to the Appdome API Reference Guide for API building instructions.
        2. Look for sample APIs in Appdome’s GitHub Repository.
    1. Add the Java and Kotlin Dumps feature to your security template.

      1. Navigate to Build > Anti ATO tab > Mobile Account Protection section in the Appdome Console.
      2. Toggle On Detect Android Memory Dump > Java and Kotlin Dumps.
        Note: The checkmark feature Java and Kotlin Dumps is enabled by default, as shown below. Java and Kotlin Dumps option

        Figure 4: Selecting Detect Java and Kotlin Dumps

    2. Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.
    Congratulations!  The Java and Kotlin Dumps protection is now added to the mobile app
  3. Certify the Java and Kotlin Dumps feature in Android Apps

    After building Java and Kotlin Dumps, Appdome generates a Certified Secure™ certificate to guarantee that the Java and Kotlin Dumps protection has been added and is protecting the app. To verify that the Java and Kotlin Dumps protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Java and Kotlin Dumps 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 Java and Kotlin Dumps has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Java and Kotlin Dumps and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Java and Kotlin Dumps Intelligence and Control in Android Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Java and Kotlin Dumps are detected. To consume and use Threat-Events™ for Java and Kotlin Dumps in Android Apps, use registerReceiver in the Application OnCreate, and the code samples for Threat-Events™ for Java and Kotlin Dumps shown below.

The specifications and options for Threat-Events™ for Java and Kotlin Dumps are:

Threat-Event™ Elements Detect Java and Kotlin Dumps Method Detail
Appdome Feature Name Java and Kotlin Dumps
Threat-Event Mode
OFF, IN-APP DEFENSE Appdome detects, defends and notifies user (standard OS dialog) using customizable messaging.
ON, IN-APP DETECTION Appdome detects the attack or threat and passes the event in a standard format to the app for processing (app chooses how and when to enforce).
ON, IN-APP DEFENSE Uses Appdome Enforce mode for any attack or threat and passes the event in a standard format to the app for processing (gather intel on attacks and threats without losing any protection).

With Threat-Events™ enabled (turned ON), Android developers can get detailed attack intelligence and granular defense control in Android applications and create amazing user experiences for all mobile end users when Java and Kotlin Dumps are detected.


The following is a code sample for native Android apps, which uses all values in the specification above for Java and Kotlin Dumps:


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.

Device Binding in the Age of AI

For years, fraud prevention solutions have tried to use Device IDs to bind (or link) a user’s account or session to a specific device to prevent unauthorized access from other devices. However, until recently, Device IDs lacked persistence and the broad threat context needed to stop fraud and ATOs …
