Replace Toast with Snackbar

[abhishekbisht1429]

Actual Behaviour

Currently brief messages at some places in the app use Toast to display brief messages to the user.

Expected Behaviour

According to android documentation -

Snackbar is now the preferred way to display brief, transient messages to the user.

https://developer.android.com/training/snackbar/

Therefore it would be better to replace the Toast with Snackbar, as it is possible that in the future the support for Toast might end.

Steps to reproduce it

• Toast is displayed when the user tries to exit the app
• Toast message is displayed when the user tires to use an option which requires PSLab device without actually connecting the PSLab device.
