How to Protect Android Memory in Android Apps Using AI
Last updated February 9, 2025 by Appdome
This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously
deliver plugins that Protect Android Memory in Android apps.
What is Android Memory Protection?
Android memory protection secures data stored in an app’s memory (RAM) during runtime, preventing attackers from accessing or modifying sensitive information like user credentials, session tokens, or in-app purchases. Attackers often exploit memory through techniques like memory dumping to steal data or manipulate app behavior, such as altering game scores. By protecting memory, apps prevent unauthorized access to sensitive data, ensuring the security of in-app transactions and data integrity, which is critical for maintaining compliance with standards that require runtime data protection in mobile environments.
How Appdome Protects Android Apps Against Memory Attacks?
Appdome’s dynamic Android Memory Protection plugin secures app-specific data stored in memory during runtime, preventing unauthorized access and modifications. By dynamically protecting sensitive data like user credentials, passwords, and in-app purchase values, Appdome ensures that attackers cannot manipulate the app’s memory for malicious purposes while the app is in use.
Prerequisites for Using Appdome's Android Memory Protection Plugins:
To use Appdome’s mobile app security build system to Protect Android Memory , you’ll need:
Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
Android Formats: .apk or .aab
Android Memory Protection is compatible with:
Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
Select the defense: Android Memory Protection.
Create and name the Fusion Set (security template) that will contain the Android Memory Protection feature as shown below:
Figure 1: Fusion Set that will contain the Android Memory Protection feature
Follow the steps in Sections 2.2-2.2.2 of this article to add the Android Memory Protection feature to your Fusion Set via the Appdome Console.
When you select the Android Memory Protection you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Android Memory Protection.
Figure 2: Fusion Set that displays the newly added Android Memory Protection protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).
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):
Figure 3: Fusion Set Detail Summary
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:
Add the Android Memory Protection feature to your security template.
Navigate to Build > Anti ATO tab > Mobile Account Protection section in the Appdome Console.
Like all other options in ONEShield™, Android Memory Protection is turned on by default, as shown below:
Figure 4: Selecting Android Memory Protection
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.
Toggle On > Android Memory Protection.

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.
Configure the User Experience Options for Android Memory Protection:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.
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.
Short message Option. This is available for mobile devices that allow a banner notification for security events.
Localized Message Option. Allows Appdome users to support global languages in security notifications.

Android Memory Protection Threat Code™. Appdome uses AI/ML to generate a unique code each time
Android Memory Protection is triggered by an active threat on the mobile device.
Use the code in Appdome Threat Resolution Center™ to help end users identify, find and resolve active threats on the personal mobile devices.
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 Android Memory Protection protection is now added to the mobile app
Certify the Android Memory Protection feature in Android Apps
After building Android Memory Protection, Appdome generates a Certified Secure™ certificate to guarantee that the Android Memory Protection protection has been added and is protecting the app. To verify that the Android Memory Protection protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
Figure 6: 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 Android Memory Protection has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Android Memory Protection and other mobile app security features are in each build of the mobile app.
Using Threat-Events™ for Android Memory Intelligence and Control in Android Apps
Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Android Memory is detected. To consume and use Threat-Events™ for
Android Memory in Android Apps, use registerReceiver in the Application OnCreate, and the code samples for Threat-Events™ for Android Memory shown below.
The specifications and options for Threat-Events™ for Android Memory are:
Threat-Event™ Elements
Protect Android Memory Method Detail
Appdome Feature Name
Android Memory Protection
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).

Using Appdome, there are no development or coding prerequisites to build secured Android Apps by using Android Memory Protection. 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.
Releasing and Publishing Mobile Apps with Android Memory Protection
After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
If you have any questions, please send them our way at support.appdome.com or via the chat window on the Appdome platform.
