Fail to connect to camera service in Example(Android Native API)

I downloaded the sdk and copied all files into new project.

and now app is working perfectly on Samsung s4 but not working in Moto X(API 23).

and my manifest file:

Please have a look at the runtime permission handling on Android API 23+.

A simple implementation is part of latest SDK Sample application, further details at
