How to force user to enable permission oontacts, Location and camera on ionic v3

i already have a working app but i need to ask for permission for use of camera, location and access to contact

You will have to add permission in config.xml later that will be added in androidmanifest,xml
Read the plugin readme/docs otherwise use cordova diagnostic plugin

I really advise to use the Diagnostics Plugin. You can easily check and ask for permissions at Runtime.

This is the error i get after following camera implementation on

Please help…

You are testing on a Desktop? The Camera Plugin only works on a real Device
