Android: Cannot call non W3C standard command while in W3C mode

The problem

On trying to create a new android session, i am seeing this message after the session gets created.
Unknown command: Cannot call non W3C standard command while in W3C mode

I don't see this issue if i remove the capability:
dc.setCapability(MobileCapabilityType.AUTO_WEBVIEW, true);

Switiching to webview works if i use driver.setContext() and i do not see W3C error.
But the error is seen with doesn't work with AutoWebview.

I am using java client 7.2.0 in this process
