Compile production-ready Android App Bundles (.aab) signed with release keystores for publishing on Google Play Store. Nativine handles Gradle build optimization, asset compression, and manifest verification automatically.
1. What is an Android App Bundle (AAB)?
An Android App Bundle (.aab) is Google Play's required publishing format for new applications:
- Play Feature Delivery: Google Play uses your AAB file to generate optimized APKs tailored to each user's device architecture (ARM64, x86), reducing download size by up to 30%.
- APK vs AAB: Use APK files for direct testing on physical Android devices. Use AAB files for uploading to Google Play Console releases.
- Release Keystore Signing: Every AAB must be cryptographically signed with a release keystore certificate before Google Play accepts the upload.
2. No-Code App Builder Setup Guide

3. Frequently Asked Questions (Q&A)
Why did Google Play give "Version Code must be higher" error?
Every time you upload an update to Google Play Console, you must increment the Version Code integer (e.g., from 1 to 2) in the App Builder before generating your new AAB package.
Can I install an AAB file directly on my Android phone?
No. Phones require .apk files for direct side-loading. To test your app locally on a phone, compile an APK package under the Builds tab.
