Questions tagged [zipalign]

zipalign is an archive alignment tool that provides important optimization to Android application (.apk) files.

The purpose is to ensure that all uncompressed data starts with a particular alignment relative to the start of the file. Specifically, it causes all uncompressed data within the .apk, such as images or raw files, to be aligned on 4-byte boundaries.
