My question is, how do we enable obfuscation for the AP

Answer 1

You can have a look here: https://source.android.com/source/jack.html

From the official documentation:

(Jack) Handles shrinking, obfuscation, repackaging and multidex. Using a separate package such as ProGuard is no longer necessary.

Please notice especially the section "Shrinking and Obfuscation" where it's mentioned that:

Jack has shrinking and obfuscation support and uses proguard configuration files to enable shrinking and obfuscation features.

And also the supported and ignored options are presented too.
