Cannot exit scan QR code without scanning a QR code

This issue is: Ready to be Built

Problem

When a user wants to add another user by scanning the QR code, the full screen camera takeover appears. This view cannot be closed - the user must scan a QR code which can be annoying if they clicked there by accident.
The only way I found to close this view was to force quit the app.

Current	Screens

Solution

Add a material.io top bar (contextual action bar) with a title and close button that takes the user back to the previous screen.

Something like this:

Edit bmarty TODO:
For all the titles to add you can reuse an existing string

• Add a title to the screen CreateDirectRoomByQrCodeFragment (see above)
• Add a title "Scan a QR code" to the screen ScanUserCodeFragment
• Add a title "Scan their code" to the screen QrCodeScannerFragment

Using the regular back button should work, but it,s maybe a bit hidden on new Android system.

Can you add a screenshot please?

Confirmed, the "back swipe" gesture works on Android but this action can be disabled so its best not to rely on it

[bmarty]

If you disable the back gesture then you should have the regular back/home/switch navigation buttons displayed at the bottom of the screen.

But I agree it will be better with a toolbar anyway.

Thanks for the screenshots by the way, here they helped me to understand that you were not talking about QR code scanning for user verification :)
