Aligning
I used the full path of zipalign. For mac, I found the executable file in Finder and clicked on it. Then, to publish my app I ran
/Users/username/development/sdk/tools/zipalign -v 4 HelloWorld-release-unsigned.apk HelloWorld.apk
instead of
zipalign -v 4 HelloWorld-release-unsigned.apk HelloWorld.apk
