It's not clear from the screen recording at what point exactly it crashed, probably at the end after initial sync is complete.

Of the three Nepal apps, only those two on 1.4.0 have this error: PRTP Gandaki, CHIS Nepal.
mHealth Lumbini is on v1.3.0-alpha-2.lumbini-ne, and this error is not seen.

I've looked into this and I think I've figured out the cause of the error. I couldn't recreate this but judging by the stack trace and the previous error which was fixed #338, I have the following findings.

Here, in the EmbeddedBrowserActivity (the main class/activity for the app) calls the Fragment OpenSettingsDialogFragment class, which will work as expected in a normal case. However, in some cases such as hibernation or pause or something that needs the app to be paused and resumed the Fragment class OpenSettingsDialogFragment fails to obtain the activity from which it is being called. Ref. Hence, the view variable here is set to null as per the exception stack trace and cannot call setOnTouchListener method.

I haven't implemented and tested this all out but the solution seems to be to implement androidx.fragment.app.Fragment and not android.app.Fragment. androidx.fragment.app.Fragment seems to have more flexibility and functionalities to deal with the required functionality.

Using Android emulator with version 12L on small desktop x86 virtual device, the error was reproduced. It occurred when using the "Split" action in the overview to start split-screen mode with a tap.

I was also able to reproduce the error on my phone when switching to a split screen view where one of the open apps was CHT.
