How to Obfuscate Security Features on Appdome
Learn to Obfuscate Security Features in Android apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.
What is the 'Obfuscate Security Feature' on Appdome?
The Obfuscate Security Features protection is an integral component of Appdome’s ONEShield suite. This innovative tool is specifically designed to hide and safeguard Appdome’s unique code. In essence, it offers businesses the benefit of using Appdome’s robust security solutions while keeping their choice of third-party security vendor undisclosed and preventing attackers from discovering where Appdome’s protections are located or how they work.
Why Use Appdome's 'Obfuscate Security Features'?
Prerequisites for Using Obfuscate Security Features:
To use Appdome’s mobile app security build system to Obfuscate Security Features , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Obfuscate Security Features
- Mobile App (.apk or .aab for Android)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
Obfuscate Security Features on Android apps using Appdome
On Appdome, follow these 3 simple steps to create self-defending Android Apps that Obfuscate Security Features without an SDK or gateway:
-
Upload the Mobile App to Appdome.
-
Upload an app to Appdome’s Mobile App Security Build System
-
Upload Method: Appdome Console or DEV-API
-
Android Formats: .apk or .aab
-
Obfuscate Security Features Compatible With: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps
-
-
Build the feature: Obfuscate Security Features.
-
Building Obfuscate Security Features by using Appdome’s DEV-API:
-
Create and name the Fusion Set (security template) that will contain the Obfuscate Security Features feature as shown below:
-
Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Obfuscate Security Features feature via Appdome Console, to add the Obfuscate Security Features feature to this Fusion Set.
-
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 2: Fusion Set Detail Summary
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory). -
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:
-
Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
-
Look for sample APIs in Appdome’s GitHub Repository
-
Figure 1: Fusion Set that will contain the Obfuscate Security Features feature
Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required). -
-
Building the Obfuscate Security Features feature via Appdome Console
To build the Obfuscate Security Features protection by using Appdome Console, follow the instructions below.
-
Where: Inside the Appdome Console, go to Build > Security Tab > ONEShield™ section.
-
How: Check whether is toggled On (enabled), otherwise enable it . The feature Obfuscate Security Features is enabled by default, as shown below. Toggle (turn ON) Obfuscate Security Features, as shown below.
Figure 3: Obfuscate Security Features option
-
When you select the Obfuscate Security Features you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Obfuscate Security Features
Figure 4: Fusion Set that displays the newly added Obfuscate Security Features protection
-
Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
-
Congratulations! The Obfuscate Security Features protection is now added to the mobile app -
-
Certify the Obfuscate Security Features feature in Android Apps
After building Obfuscate Security Features, Appdome generates a Certified Secure™ certificate to guarantee that the Obfuscate Security Features protection has been added and is protecting the app. To verify that the Obfuscate Security Features protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
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 Obfuscate Security Features has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Obfuscate Security Features and other mobile app security features are in each build of the mobile app
Using Threat-Events™ for Security Features Intelligence and Control in Android Apps
Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Security Features is detected. To consume and use Threat-Events™ for Security Features in Android Apps, use registerReceiver in the Application OnCreate, and the code samples for Threat-Events™ for Security Features shown below.
The specifications and options for Threat-Events™ for Security Features are:
Threat-Event™ Elements | Obfuscate Security Features Method Detail |
---|---|
Appdome Feature Name | Obfuscate Security Features |
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). |

The following is a code sample for native Android apps, which uses all values in the specification above for Obfuscate Security Features:
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 Obfuscate Security Features. 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 Obfuscate Security Features
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:
- Customizing, Configuring & Branding Secure Mobile Apps
- Deploying/Publishing Secure mobile apps to Public or Private app stores
- Releasing Secured Android & iOS Apps built on Appdome.
