created issue #1

Component used: Fragment
Version used: 1.1.0-alpha05

There's a number of cases where Fragments should be capped at a lower Lifecycle than the FragmentManager/Activity. For example, off screen pages of a ViewPager shouldn't be resumed.

Ideally, this would be something you could do as part of a FragmentTransaction via an API like:

supportFragmentManager.beginTransaction()
.setMaxLifecycle(fragment, Lifecycle.State.STARTED)
.commit()

Setting the max lifecycle back to Lifecycle.State.RESUMED would effectively remove the restriction (since that's the highest lifecycle state).

This should allow the deprecation of the setUserVisibleHint() API.

This error usually indicates misconfiguration, as @Composable function is not transformed. Make sure you applied Compose compiler to that module.

ap...@google.com <ap...@google.com> #3Apr 16, 2019 05:21PM

I presumed the same, but i think we apply the compose compiler to all of our modules. I'll check again.

Also the fact this works fine for the previous version is odd.

previous versions
compiler 1.5.4
kotlin 1.9.20
ksp 1.9.20-1.0.14

I have the same problem. Seems like it is related to build cache, code stopped compiling when I made an implementation of an open Composable function.

same with compiler 1.5.8

Re #4, it is fixed in compiler v1.5.5

Re #5, could you reproduce in a sample project? The transform works correctly when I try to repeat the steps above.

ap...@google.com <ap...@google.com> #7Apr 18, 2019 07:02PM

Hi,

I have been unable to produce a sample project so far.
I have fixed it in our project by removing one layer of inheritance.

Our paparazzi tests had been structured like
TestClass <- PaparazziText (open) <- BasePaparraziTest (abstract)

removing the abstract class has fixed the issue.

ap...@google.com <ap...@google.com> #8Apr 18, 2019 10:32PM

Able to reproduce it with a commit to a github project.

Call setMaxLifecycle() after add() in FragmentStatePagerAdapter

SetMaxLifecycle() must be called after add() or an
IllegalArgumentException will be called because the fragment is not yet
attached to the FragmentManager.

In instantiateItem(), if used, the call the setUserVisibleHint() will still
happen before the fragment is added. If only the current fragment is resumed,
setMaxLifecycle() will be called after add().

While you're at it, can you rename `getItem(int position)` to `createFragment(int position)`? It's a very common source of bugs.

Shouldn't non-visible fragments also be stopped, not just paused?

Fragment docs mention that fragment is started when it is visible to the user. If fragment is completely hidden, then it should be stopped, right?

Re #15 - that is not possible for FragmentPagerAdapter/FragmentStatePagerAdapter since ViewPager supports margins (i.e., the offscreen pages *are* partially visible), among other complications.

In a non-ViewPager context, setMaxLifecycle() certainly supports stopping Fragments.

I use FragmentVPAdapter with 4 fragments, and there are their life logs, two of them had called onResume , but fragment2 called onPause after onResume:

onAttach 1
onCreate 1
onAttach 2
onCreate 2
onCreateView 1
onActivityCreated 1
onStart 1
onResume 1
onPause 1
onCreateView 2
onActivityCreated 2
onStart 2
onResume 2
onPause 2
onResume 1

```
mViewpager = findViewById(R.id.viewpager)
val adapter = FragmentVPAdapter(supportFragmentManager,RESUME_ONLY_CURRENT_FRAGMENT)
mViewpager.adapter = adapter

class FragmentVPAdapter(
fragmentManager: FragmentManager, @Behavior behavior: Int
) : FragmentStatePagerAdapter(
fragmentManager, behavior
) {

val fragments = listOf<Fragment>(
MyFragment.newInstance(1),
MyFragment.newInstance(2),
MyFragment.newInstance(3),
MyFragment.newInstance(4)
)

override fun getItem(position: Int): Fragment {
return fragments[position]
}

override fun getCount(): Int {
return fragments.size
}
}

Re #17 - please file new issues, rather than tacking issues onto already closed issues. In your case, I believe your issue is already covered by
