How to get zipalign for mac?

Question

I already have a release unsigned version apk and I am trying to sign it on my mac. On the last step it suggests to zipalign the signed apk but mac doesn't have zipalign.

I did 'brew search ' still can't find it. I searched online and can't find standalone zipalign script. I even downloaded around 90M Android sdk tool from http://developer.android.com/sdk/index.html#Other but still found no zipalign inside.

So my question is, given you an "apk" file to sign on mac, how to get through the last "zipalign" step?

Are you indicating in order to use 'zipalign' I have to download 250M android studio and install it on mac? Cause all those posts mentioned some sort of android sdk install path. – Feuar

I think so yes but no guarantee – Wycoff

if you have the SDK installed you should be able to do "android zipalign -v file.apk dest.apk" on your command line – Vibrissa

Thanks the info from RC.

I finally got through this. I did in following steps:

1. Download 250M+ android studio ide dmg from official site. Drag it into Application folder
2. Open it, and it automatically downloads a lot of additional stuff
3. I even created a empty new project.

Then in certain step(I am not sure which step) it created zipalign here:

~/Library/Android/sdk/build-tools/22.0.1/zipalign

If you only need "zipalign", you don't need to redo those steps, which takes time and disk space. I extracted it into the github(Can't believe no one has extracted it -_- ):

Mac users: If you get an error similar to: unable to execute ./zipalign: Bad CPU type in executable, you may need the 64bit version of ZipAlign. Available here: github.com/spanishsnapper/zipalign (extracted from Studio 29.0.2) – Sino

From your Mac terminal:

Add adb to command line path:

echo 'export ANDROID_HOME=/Users/$USER/Library/Android/sdk' >> ~/.bash_profile

Add build tools to command line path:

echo 'export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/build-tools/28.0.2' >> ~/.bash_profile

Refresh command line with:

source ~/.bash_profile

Then you can run it with:

zipalign -v -p 4 my-app-unsigned.apk my-app-unsigned-aligned.apk

make sure build-tools/version matches your installed version mine was 28.0.3. – Cracow

You can use find ~/Library/Android/sdk/build-tools -name "zipalign" to find the zipalign path in your system – Cracow

Expecting that you already have AndroidSDK, then just use this in terminal sudo ln -s ~/Library/Android/sdk/build-tools/34.0.0/zipalign /usr/local/bin/
