I want to use minifyEnabled true

and try to generate signed Apk but get error

Warning: Exception during processing java.io.FileNotFoundException: \ app \ build \ intermediates \ proguard-rules \ release \ aapt_rules.txt (the system cannot find the path specified).

What can I do to avoid this error?
