Zipalign failure when signing app(w/ screenshot)

Hi guys, Im using macincloud, which comes with Android Studio and SDK apparently.
When signing the app, the zipalign has a red exclamation mark. (The key password is also getting that too, but its because I messed up the passwords when creating the keystore, so now when I type the password, it doesn't go through. I tried recreating the key multiple times, changing the password, but its probably messed up now.)
Anyways, how do I fix the zipalign part? And the password error?

Zipalign has a new location, it is now under sdk -> build tools -> 20.0.0
Thanks, I looked and it turned out the sdk folder was gone. The only Android support was an Android beta program that wasn't the SDK but meant to replace it, but was a bit outdated. I had to download and implement the real android SDK, fixed the password issue, and it worked.
Once I downloaded the SDK, I followed the path you put and found the zip align. Thanks again.
No problem, glad i could help.
