I have tried to call some methods of CameraDialog.java in my MainActivity.java but unable to do so and got some error.

Here is the code which I have tried:-
CameraDialog camdiag = new CameraDialog();
camdiag.triggerUSBCam();

This is the error which I have got during run:-
Attempt to invoke virtual method 'java.lang.Object android.widget.Spinner.getSelectedItem()' on a null object reference

Here is the second code which I have tried:-
CameraDialog camdiag = new CameraDialog();
camdiag.updateDevices();

This is the error which I have got during run:-
java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.Resources android.content.Context.getResources()' on a null object reference

Actually, I just want to bypass this camera dialog.
If there is any other way then please let me know.

Thanks-

How can I set the ApiConfig class to make my app works?

I want to use the USB Camera without showing pop menu. But when I remove the the menu from the code then the USB Camera does not work.

So, how can I remove the pop menu so that the USB Camera still works.

Dear Sir,

According to the title above, may I know how should I initialize the project?
Sorry, I am new to this field.
I would also like to ask, for your knowledge about OpenTok, do you think is it possible to capture laptop's webcam view and live stream it to Android apps with OpenTok?

Thank you

I have created a project in Eclipse and I want to want to use custom_webcam_capturer code in that project but I do not know how can I use this Android Studio code in Eclipse project without any issue.

Please help!!!
