Yes sir I have already used native URL with filepath plugin but same result.
Last msg I have asked a question:-
ur not using "mimeType" in ur code.can u explain me why?

Hi, It's long ago I had created this Gist, so I'm finding difficulty in recalling why mimeType is not used. If all the things are correct but still your not able to upload the image captured from camera means, I would suggest you this repository of mine.

1. Convert image captured from camera to base64 format.
2. Ensure Image is converted to base64 format by logging the output of the base64 plugin.
3. Upload base64 to server and convert it into Image file there. All the modern programming language has support to convert base64 into actual file.
