Answer 1

I have faced the same issue after upgrading to latest studio.

I am not sure about the root cause but what I did is

comment below line from volley build.gradle

apply from: 'bintray.gradle'

As I can see there many project are there in you dependencies. If possible comment same from all and try syncing again.
