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 alignmentrelative 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. This allows all portions to beaccessed directly with mmap() even if they contain binary data with alignmentrestrictions. The benefit is a reduction in the amount of RAM consumed when running theapplication.

Hello, I have build my app. 1 point 14 days ago. $ zipalign -v 4 HelloWorld.apk Now we have our final release binary called HelloWorld.apk and we can release this on the Google Play Store for all the world to enjoy! (There are a few other ways to sign APKs. $./zipalign -v 4 android-release-unaligned.apk HelloWorld.apk instead of the proposed one: $ zipalign -v 4 HelloWorld-release-unsigned.apk HelloWorld.apk And it worked! If you only need zipalign to get your Android app ready for being published you may try to just use the enclosed zipalign tool instead of downloading the entire Android Studio. Zipalign is a program that is shipped with the Android SDK.You can find it under the build-tools folder. It is highly advised that you use Visual Studio's Publishing feature to accomplish the complete signing and zipaligning process for you.
This tool should always be used to align your APK file before distributing it to end-users. TheAndroid build tools can handle this for you. Android Studio automatically aligns your APK.
Caution: You must use zipalign at one of two specific points in the app-building process, depending on which app-signing tool you use:
- If you use
apksigner, zipalign must only be performed before the APK file has been signed. If you sign your APK using apksigner and make further changes to the APK, its signature is invalidated. - If you use
jarsigner, zipalign must only be performed after the APK file has been signed.
The adjustment is made by altering the size of the 'extra' field in the zip Local File Header sections. Existing data in the 'extra' fields may be altered by this process.

Usage
To align infile.apk and save it as outfile.apk:
To confirm the alignment of existing.apk:
The <alignment> is an integer that defines the byte-alignment boundaries. This must always be 4 (which provides 32-bit alignment) or else it effectively does nothing.
Flags:
-f: overwrite existing outfile.zip-v: verbose output-p: outfile.zip should use the same page alignment for all shared object files within infile.zip-c: confirm the alignment of the given file
zipalign is an archive alignment tool that provides importantoptimization to Android application (.apk) files. The purpose is to ensure that all uncompressed data startswith 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. Thisallows all portions to be accessed directly with mmap() even if theycontain binary data with alignment restrictions. The benefit is a reduction in the amount of RAM consumed when running the application.
This tool should always be used to align your .apk file before distributing it to end-users. The Android build tools can handlethis for you. When using Eclipse with the ADT plugin, the Export Wizardwill automatically zipalign your .apk after it signs it with your private key. The build scripts usedwhen compiling your application with Ant will also zipalign your .apk,as long as you have provided the path to your keystore and the key alias inyour project ant.properties file, so that the build tools can sign the package first.
Caution: zipalign must only be performedafter the .apk file has been signed with your private key.If you perform zipalign before signing, then the signing procedure will undothe alignment. Also, do not make alterations to the aligned package.Alterations to the archive, such as renaming or deleting entries, willpotentially disrupt the alignment of the modified entry and all laterentries. And any files added to an 'aligned' archive will not be aligned.
