Solution

This issue is referenced here which occurs in project including non ASCII class names. The issue will be addressed from version 2.4 of gradle Android plugin (not yet released at this time).

An alternative is to downgrade to 2.2.3 :

classpath 'com.android.tools.build:gradle:2.2.3'

I was just going to move to v2.2.3 of Android Studio, this saved me. Thanks alot.

These non-ascii chars are coming from Razorpay dependencies. If you check their code, they're using obfuscation that uses non-ascii chars. Seems they're taking great pains to make deciphering their SDK harder XD

Is there a way to enable instant run in this case??
