Improve UI of scanning devices of bluetooth

[ajay-prabhakar]

Software and hardware versions

Android Samsung J8 and oneplus 6

Problem description

Currently, while scanning the Bluetooth devices around we are using progress dialog according to material design showing progress dialog while the adapter is loading somewhat a bad UI, so while scanning devices without showing the progress dialog show a circular progress bar which is somewhat like I give the gif below so, that user can observe scanning and he can able to click the device and start the transferring the forms without clicking the stop scanning in progress dialog

from this comment @lakshyagupta21 asked an improvement a bit I got this idea

Current Approach

Proposed Approch

Steps to reproduce the problem

Go to Main Activity
Click Receive(if you are not in Bluetooth mode switch to Bluetooth mode)
Observe the progress dialog and how recycler view is loading

Expected behavior

show a circular progress bar which is somewhat like I give the gif above
