Preparing for Google Play Store Submission in Jetpack Compose

Introduction

Developing an Android app using Jetpack Compose offers a modern and efficient way to build UI. However, before launching your app on the Google Play Store, you need to navigate the submission process effectively. This guide walks you through essential steps to prepare your Jetpack Compose app for Play Store submission, covering key considerations such as technical, design, and compliance aspects.

Step 1: Optimize and Finalize Your App

1.1 Ensure App Stability and Performance

Before submitting your Jetpack Compose app, thoroughly test it for performance and stability:

• Use Android Profiler to monitor CPU, memory, and network usage.
• Optimize recompositions in Jetpack Compose to prevent unnecessary UI redraws.
• Ensure smooth animations with tools like Compose Preview and Layout Inspector.
• Run performance tests with tools like Macrobenchmark to analyze rendering times.

1.2 Handle Different Screen Sizes and Orientations

Jetpack Compose simplifies responsive UI, but ensure your app adapts well across various devices:

• Use Modifier.fillMaxSize() and Modifier.wrapContentSize() appropriately.
• Support landscape and portrait modes with WindowSizeClass from the Jetpack Compose Adaptive UI library.
• Test on different screen densities using Android Emulator or physical devices.

1.3 Implement Dark Mode and Theming

• Use MaterialTheme to define light and dark themes.
• Ensure UI elements are readable in both modes.
• Test theme switching with Dynamic Color Support on Android 12+.

Step 2: Prepare Necessary App Information

2.1 Define App Name and Package ID

The package ID (e.g., com.example.myapp) is permanent once published, so choose it carefully.

2.2 Create an App Icon and Feature Graphics

• Follow Google Play icon guidelines (512x512px, PNG format, transparent background).
• Prepare a feature graphic (1024x500px) to promote your app visually on the Play Store.

2.3 Write an Engaging App Description

• Clearly define the app’s purpose and features.
• Use SEO-friendly keywords without spamming.
• Highlight unique selling points and user benefits.

Step 3: Implement Google Play Policies and Compliance

3.1 Review Google Play’s Developer Policies

Ensure compliance with:

• Data safety: Declare how user data is collected and processed.
• Privacy policy: Link a GDPR-compliant privacy policy on the Play Store listing.
• Content policies: Avoid inappropriate content, misleading claims, or deceptive behavior.

3.2 Implement Permissions Properly

• Request only necessary permissions.
• Justify permissions in the Google Play Console.
• Use Foreground Services instead of background tasks for better power efficiency.

Step 4: Generate and Sign Your APK/AAB

4.1 Choose the Right Format: APK vs. AAB

Google Play prefers Android App Bundles (AAB) for more efficient delivery. Use the following command to generate an AAB:

./gradlew bundleRelease

4.2 Enable App Signing

• Use Google Play App Signing for enhanced security.
• Generate a keystore file using:

keytool -genkeypair -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-key-alias

• Configure signingConfigs in build.gradle:

android {
    signingConfigs {
        release {
            storeFile file("my-release-key.jks")
            storePassword "your-password"
            keyAlias "my-key-alias"
            keyPassword "your-key-password"
        }
    }
}

Step 5: Test with Internal and Closed Testing Tracks

5.1 Upload to Internal Testing

• Use Google Play Console > Testing > Internal Testing to distribute the app to a small group.
• Collect feedback before a wider rollout.

5.2 Use Firebase Test Lab

• Run automated UI tests to detect crashes before production.
• Test on real devices using Firebase Cloud.

Step 6: Submit Your App to Google Play

6.1 Create a Google Play Developer Account

• Pay a one-time $25 fee to register as a Google Play Developer.
• Set up a payment profile if your app includes in-app purchases.

6.2 Fill Out Store Listing Details

• Provide a high-quality app title, description, and graphics.
• Upload at least 2–8 screenshots for different device sizes.
• Add a promo video (optional) for extra engagement.

6.3 Set Up Pricing and Distribution

• Choose between free or paid models.
• Select the countries where your app will be available.

6.4 Submit for Review

• Review warnings or errors in the Pre-launch report.
• Click Publish and wait for Google’s approval (typically 24-48 hours).

Conclusion

Submitting a Jetpack Compose app to the Google Play Store involves careful preparation, from optimizing UI performance to meeting compliance requirements. By following these steps, you can ensure a smooth submission process and a successful launch for your Android application.
