How to Reduce Android App Size Without Losing Features
Practical techniques to shrink Android app size: App Bundles, R8, resource optimisation, dynamic features and dependency audits.
In many markets, every extra megabyte reduces installs — users on low-storage phones and costly data plans skip large apps.
Use Android App Bundles
Publishing an AAB lets Google Play deliver only the code and resources each device needs.
Enable R8 shrinking
R8 removes unused code and obfuscates the rest. Configure keep rules carefully and test release builds.
Optimise resources
- Convert PNGs to WebP
- Use vector drawables for icons
- Remove unused resources with resource shrinking
- Limit bundled languages to those you support
Audit dependencies
One convenience library can add megabytes. Review your dependency tree and replace heavy libraries with lighter alternatives.
Dynamic feature modules
Deliver rarely used features on demand instead of at install.
Measure continuously
Track app size in CI and fail builds that exceed a budget.
