Important Note: Zipalign and APK Signing
A critical mistake beginners make is signing the APK before zipaligning.
The Rule: Zipalign must be performed BEFORE signing the APK.
Why? Because signing attaches a signature file that must remain intact. If you modify (align) an already signed APK, you break the digital signature. The workflow should always be:
- Build unsigned APK.
- Run Zipalign on the unsigned APK.
- Sign the aligned APK using
apksignerorjarsigner.
