If zipalign command is not found from Command-Line add file path of zipalign to environmental variables. As mentioned above, it's never good to change exe file location. For Windows users: Add to User->PATH->"path to zipalign folder" In my case it path was C:\adt-bundle-windows-x86_64-20140702\sdk\build-tools\android-4.4W. In that folder is zipalign -v 4 <YOUR_APP_NAME> app-release-final.apk share | follow | answered Jun 18 '19 at 23:47. rohan parab rohan parab. 659 1 1 gold badge 8 8 silver badges 10 10 bronze badges. add a comment | 3. for win10 its in c:\Users, such as: C:\Users\\Android\sdk\build-tools\ share | follow | answered Apr 30 '18 at 20:05. user542319 user542319. 293 2 2 gold badges 4 4 silver badges 14 14 bronze zipalign [-f] [-v] <alignment> infile.apk outfile.apk. where infile.apk is the source file, and outfile.apk is the output file. Furthermore, you can also verify the alignment of an APK file using the following command: zipalign -c -v <alignment> existing.apk. where existing.apk can be any application package that you need to get verified. Also, the <alignment> tag in both the commands needs to 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. This allows all portions to be $ ./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.
