Accelerate With Baseline Profiles in Android Apps with Appdome

Discover how to effectively enhance Android app performance by customizing your app with Baseline Profile in a mobile CI/CD environment using Appdome’s Data-Driven DevSecOps™ build system.

What is Baseline Profile Optimization on Appdome?

Baseline Profile optimization allows Android developers to improve app performance by utilizing Ahead-of-Time (AOT) compilation for critical code paths. The Baseline Profile consists of a .txt file generated using Android Studio, which lists important methods and their respective priority levels based on how often they are used. This profile is then compiled into a .prof file, providing performance benefits during app startup and runtime. However, modifications to app files, such as when adding security features, can disrupt this optimization, requiring the .prof file to be regenerated to ensure performance benefits are retained in the secured version of the app.

How Appdome Improve App Performance with Baseline Profile Optimization?

Appdome’s Accelerate with Baseline Profiles optimization feature allows developers to upload their profile.txt files using the --baseline_profile switch. Once uploaded, Appdome regenerates the .prof file to correspond with the protected app after security features are applied. This ensures that the app retains its performance optimizations, even after being secured. By leveraging Appdome’s API, developers can integrate this process into their CI/CD pipelines for automatic profile management with each new build, ensuring that the Baseline Profile is always up to date and optimized without manual intervention.

Prerequisites for Using App Customization with Baseline Profile:

To use Appdome’s mobile app security build system to Customize an App with a Baseline Profile, you’ll need the following:

• Appdome account (create a free Appdome account here)
• A license for ONEShield™ – Accelerate Protected App with Baseline Profiles
• Mobile App (.apk or .aab for Android)

Steps to Integrate Baseline Profile:

1. Designate the mobile app to be protected.
   1.1 Upload a mobile app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
   1.2 Android Formats: .apk or .aab / iOS Formats: .ipa
   1.3 Accelerate Protected App with Baseline Profiles is compatible with Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova, and other Android apps.

2. Select the defense: Accelerate Protected App with Baseline Profiles.
   2.1. Create and name the Fusion Set (security template) that will contain the Accelerate Protected App with Baseline Profiles feature as shown below:

   

   Figure 1: Fusion Set that will contain the App Customization with Baseline Profile feature
   Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).
   

   2.1.1. Follow the steps in Sections 2.2-2.2.2 of this article to add the App Customization with Baseline Profile feature to your Fusion Set via the Appdome Console.

   2.1.2. When you select the App Customization with Baseline Profile feature, you’ll notice that the Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains the App Customization with Baseline Profile feature.

   Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).
   2.1.3. 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):

   Note: This is crucial, as you will need it to make the API call.
   

   2.1.4 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 systems:
   2.1.4.1 Refer to the Appdome API Reference Guide for API building instructions.
   2.1.4.2 Check Appdome’s GitHub Repository for sample APIs.

   2.2. Add the Accelerate Protected App with Baseline Profiles feature to your security template.
   2.2.1. Navigate to Build > Security tab > Appdome Dev Options section in the Appdome Console.

   2.2.2. Upload a Baseline Profile file.
   

    

   2.3. Initiate the build command either by clicking Build My App at the bottom of the Build Workflow or via your CI/CD as described in Section 2.1.4.

Setup your API call

1. Copy your App ID
   
2. Prepare to make a POST request to the appropriate Appdome API endpoint.
3. Refer to the image provided for the correct parameter setup:
   
4. Configure the API Parameters:
   • app_id: The unique identifier for your app obtained from the upload response.
   • fusion_set_id: The Fusion Set ID you copied earlier.
   • action: Set this to “fuse” to initiate the integration process.
5. Baseline_profile: Attach the profiles.zip file containing your Baseline Profile.
6. Send the API Request
7. Appdome’s system will process the Baseline Profile along with your specified Fusion Set and apply the necessary configurations to your app.
8. Verify the Integration

After the API call, you can verify the integration by checking the build status on the Appdome platform. Ensure that the Baseline Profile has been correctly applied as per your configuration.

After successfully integrating the Baseline Profile using the API, your Android app will benefit from optimized performance through enhanced specific code paths. This integration not only improves app performance but also maintains the efficacy of Appdome’s security measures.

This streamlined process simplifies the integration of performance optimization features without the need for manual adjustments in the Fusion Set, allowing for greater flexibility and efficiency in your CI/CD pipeline.
