如果您使用的是 IDE“构建签名的 apk”GUI 功能，则不需要 zipalign，因为最后一步将由 IDE 完成。
如果您使用命令行，请执行以下步骤:Signing manually

Zipalign

Caution: zipalign must only be performed after the .apk file has been signed with your private key. If you perform zipalign before signing, then the signing procedure will undo the alignment. Also, do not make alterations to the aligned package. Alterations to the archive, such as renaming or deleting entries, will potentially disrupt the alignment of the modified entry and all later entries. And any files added to an "aligned" archive will not be aligned.
