Ionic Native Camera question with DevApp

I am relatively new to Ionic and I am trying an example which is very similar to this.

When I run it in my local

$ ionic cordova run browser

It runs fine, takes pictures and displays it as expected but I am unable to run this successfully in DevApp.

Usually for other apps, I run

$ ionic serve --devapp

and as long as I am connected to the same WiFi on the phone, I see the app and I can use it but this time, I am unable to see the app.

I tried a workaround with entering the IP address and port but when I do this, everything works fine except that it takes the picture etc but it’s not displaying inside the tag. Any help would be appreciated.

When I am using cordova, how do I make it work right on DevApp?
