- Measure firstUse the APK/AAB size breakdown to find the biggest contributors before optimising.
- Ship an App BundlePublish an .aab so Google Play delivers per-device code and resources.
- Enable R8 code shrinkingminifyEnabled true removes unused classes and methods in release builds.
- Enable resource shrinkingshrinkResources true drops resources no longer referenced after shrinking.
- Strip unused densities/localesUse resource configuration splits or bundle config to ship only what's needed.
- Use WebP / vector drawablesConvert PNGs to WebP and simple icons to vector drawables.
- Compress and right-size imagesRemove oversized art; avoid duplicate assets across densities.
- Trim native librariesKeep only required ABIs; let the bundle split per-ABI.
- Remove debug/unused dependenciesDrop libraries you don't ship; avoid pulling whole SDKs for one feature.
- Avoid uncompressed assetsDon't store large raw files in assets/ when they can be compressed.
- Reuse resourcesConsolidate near-duplicate drawables, strings, and layouts.
- Re-measure after each changeConfirm the size actually dropped and nothing broke.
