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.

Answer 1

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

Answer 2

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 -_- ):
