created issue #1

Dec 23, 2020 01:53PM

Component used: Fragment Version used: 1.3.0-rc01 Devices/Android versions reproduced on: No specific version

If this is a bug in the library, we would appreciate if you could attach:

Sample project to trigger the issue.
A screenrecord or screenshots showing the issue (if UI related).

With Fragment 1.3.0-rc01, doing a fragment transaction in viewLifecycleOwner.lifecycleScope in the onViewCreated crashes the application.

Crash doesn't happen if transaction happen outside of viewLifecycleOwner.lifecycleScope or if we use launchWhenStarted instead of launch.

I used NavigationBasicSample application with updated fragment library version (1.3.0-rc01) and added onViewCreated method in TitleScreen

Added code to reproduce the crash.

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        viewLifecycleOwner.lifecycleScope.launch {
            parentFragmentManager.beginTransaction()
                    .replace(R.id.my_nav_host_fragment, Register())
                    .commit()
//            Both of them fails
//            findNavController(this@TitleScreen).navigate(R.id.action_title_screen_to_register)
        }

//        Calling navigation outside of the lifecycle scope doesn't crash
//        parentFragmentManager.beginTransaction()
//                .replace(R.id.my_nav_host_fragment, Register())
//                .commit()
    }

Marked as fixed.

Project: platform/frameworks/support
Branch: androidx-master-dev

commit c60f33e229e31ab328ef6b59dab63b264954831c
Author: Alexandre Elias <aelias@google.com>
Date: Fri Jul 10 16:23:09 2020

Semantics no-op cleanups

Partly in response to lmr's broad code review, I did a pass of
superficial API/implementation cleanup. The main changes are:

- I changed each Boolean SemanticsProperty where false is equivalent to
not being present to take "Unit" instead. This is conceptually
clearer: it avoids questions like "can I cancel out a semantics from a
merged child by setting it to false?" Because "property = Unit" looks
weird, I also changed the style of these to "property()".

- I moved the Semantics id generator closer to where it's used, in
SemanticsModifierCore. I made it internal and an AtomicInt.
(Note that integer ids are heavily used in the Android
AccessibilityNodeInfo APIs so I can't simply remove them entirely.)

- I deleted dead code. Some examples include SemanticsHintOverrides,
a public API not connected to anything, and SemanticsPropertyKey
merge() open method which is never called. (In both cases I have
a different plan in mind for accessibility.)

Fixes: 145951226
Fixes: 145955412
Test: existing tests
Relnote: "Single-value semantics properties now use a calling style.
For example, 'semantics { hidden = true }' is now written as:
'semantics { hidden() }'."

Is there a way we can pull in the fix from depending directly on some sort of nightly build, rather than reverting rc01?

https://androidx.dev/ has details on how to use snapshot builds

Possible similar: in alpha06 all is ok but in rc01, rc02:
