How to Obfuscate Non-Native Android & iOS Code and Frameworks

Last updated January 27, 2022 by Aaron Singer


Appdome’s Non-Native Code Obfuscation obfuscates your source code in the application itself. The files are encrypted inside the application file. This means that no one will be able to read your application contents if they extract its files.

This Knowledge Base article summarizes the steps needed to obfuscate Non-Native Mobile Apps using Appdome’s Non-Native Code Obfuscation. Non-Native Code Obfuscation can be added to any Xamarin, Cordova or React Native JS application on iOS or Android instantly, without code or coding.

Obfuscating non-native mobile apps is a complex and time-consuming process. Several methods and tools need to be employed and the development resources needed to complete the task are highly specialized. Appdome simplifies the challenge of obfuscating non-native mobile apps by eliminating the need for specialized tools or development resources.

We hope you find it useful and enjoy using Appdome!

About Non-Native Code Obfuscation

Using Appdome, there are no development or coding prerequisites. For example, there is no SDK, libraries, or plug-ins to implement. The Appdome technology adds Non-Native Code Obfuscation and relevant standards, frameworks and more to the app automatically, with no manual development work at all. Using Appdome, mobile apps will use Non-Native Code Obfuscation to encrypt Non-Native Code files as if this functionality was natively coded in the application.

Let’s take an application created using “Cordova JS” (this is applicable to the other Non-Native Code solutions as well) take the “.apk”, the “.aab” or “.ipa” file and change the file extension to “.zip”. Now that it’s a zip file, you can extract the source files from it. extract the files to a new folder, for iOS under “Payload/Yourapp/www” and for Android under “assets/www”, you will find the Cordova Javascript files, if you open them – you will see a clear-text representation of the Cordova and your source code.

Now try to build the application with Non-Native Code Obfuscation on, and do the same thing again. If you look at the javascript files in the “www” folder, you can see that they are encrypted. Try installing the application on your phone – and it works just the same as before.

Prerequisites for Using Appdome for Non-Native Code Obfuscation

This article is for organizations and mobile developers that are using Non-Native Development Environments to write code, this includes “Cordova JS”, “React Native JS”, and “Xamarin”. Native Code is an application that is written in the native language of the device and is compiled to run directly on the application. This means that the source code of the application turns into a binary file. Non-Native Code is when the application is written in a high-level programming language (usually JavaScript, C#). The source code files are not compiled into a binary, but instead, they are saved as-is inside the application itself. When the application starts, it reads the code (clear-text) from the saved source code files and runs the code from there. This means that all of your code is available to anyone with the application file in hand.

In order to use Non-Native Code Obfuscation, your application must be using one of the following frameworks: Xamarin, Cordova JS, React Native JS
