Sep 25, 2023 04:05PM

Steps to reproduce:
1) navigate from MainFragment to FirstFragment
2) navigate to SecondFragment

The SecondFragment pops back to the FirstFragment in its onViewCreated method. Then back in the FirstFragment, we pop off the FirstFragment and navigate to the ThirdFragment, this is where app crashes.

This worked perfectly fine with 2.5.3.

Can you pls have a look since this prevents updating to a version newer than 2.5.3?

Stack trace:
java.lang.IllegalArgumentException: The fragment FirstFragment{2c65689} (e99e2eaa-406a-4082-ae76-ad82c6fb308e id=0x7f080138 tag=4a0f0ba7-9c35-4ffb-8791-20508f1c4bd1) is unknown to the FragmentNavigator. Please use the navigate() function to add fragments to the FragmentNavigator managed FragmentManager.

Re-factor how errors are dismissed when query is re-written

This CL changes how we handle errors/warnings if query is
re-written.
There was a bug in expandProjection where we would report warnings
for things that Room already fixes automatically (

b/140759491

).
The solution to that problem (I7659002e5e0d1ef60fc1af2a625c0c36da0664d8)
solved it by deferring validating of columns until after re-write
decision is made. Unfortunately, this required changing PojoRowAdapter
to have a dummy mapping until it is validating, make it hard to use
as it does have a non-null mapping which is not useful.

This CL partially reverts that change and instead rely on the log
deferring logic we have in Context. This way, we don't need to break
the stability of PojoRowAdapter while still having the ability to
drop warnings that room fixes. This will also play nicer when we
have different query re-writing options that can use more information
about the query results.
