please note this

For Android's permission, you have to configure it yourself (using Dexter, etc.). This plugin is made to support my other plugin adv_image_picker, so this permission is handled in adv_image_picker

On Android, you have to request permission manually, you can use dexter or another permission requestor plugin on Java. or you can see my code at adv_image_picker

or you can manually set camera permission on Android setting
