Optimize Load Time for Android Dex Obfuscation

Last updated November 30, 2023 by Appdome

Learn to Prevent long loading times in Mobile apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

How does App Obfuscation Affect Loading Times?

Obfuscation involves removing information that is not required for the program, but is useful to the programmer.  As a result, applying obfuscation usually makes the code smaller, thereby shortening the app’s loading time. However, when security-heavy obfuscation is applied,  which adds more code to the program in order to make reverse analysis more difficult, the application will take more time to load.

How does the Favor Loading Time Option Work?

When enabled (toggled On), the Favor Loading Time option automatically detects and optimizes obfuscation of publicly available components. In so doing, the application loading time is accelerated while the obfuscation remains intact.

Prerequisites for Using Favor Loading Time:

To use Appdome’s mobile app security build system to Prevent long loading times , you’ll need:

Prevent long loading times on Mobile apps using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Prevent long loading times 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. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
    4. Favor Loading Time Compatible With: Obj-C, C+, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more
  2. Build the feature: Favor Loading Time.

    1. Building Favor Loading Time by using Appdome’s DEV-API:

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

        Figure 1: Fusion Set that will contain the Favor Loading Time 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 Favor Loading Time feature via Appdome Console, to add the Favor Loading Time 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, as shown in Figure 1 above, and get 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, Cirlce 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 Favor Loading Time feature via Appdome Console

      To build the Favor Loading Time protection by using Appdome Console, follow the instructions below.

      1. Where: Inside the Appdome Console, go to Build > Security Tab > TOTALCode™ Obfuscation section.
      2. When you select the Favor Loading Time you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Favor Loading Time

        Fusion Set applied Favor Loading Time

      3. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
    Congratulations!  The Favor Loading Time protection is now added to the mobile app

Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using Favor Loading Time. 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 Favor Loading Time

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:
