@yogeshcprajapati Can you give us more details, how do you get the error?

What device do you used? Which android version? Which google playservices version? etc

[yogeshcprajapati]

@fvermeulen I have managed to solved it. If we call TakePicture method under separate task then it is working fine. Below is the working code. System.Threading.Tasks.Task.Run(() => { cameraSource.TakePicture(.......); }

Sorry for wrong reporting...
