I have a screen that's making use of AndroidView to contain a layout that in turn contains a com.google.android.gms.maps.SupportMapFragment. It works fine if that's only screen but just added some navigation and when I show another screen and then come back to this one again I'm getting following. Is there any recommended approach available right now to work around this?

Binary XML file line #6: Duplicate id 0x7f08009a, tag null, or parent id 0xffffffff with another fragment for com.google.android.gms.maps.SupportMapFragment

can you file bug for this?

[John O'Reilly]

just created https://issuetracker.google.com/issues/160765224 ....let me know if you need any more info

[John O'Reilly]

I guess this is general issue for child fragments included this way....but is hope that a Google map will be supported as first class composable?

Also, please never use the <fragment> tag, use FragmentContainerView

[John O'Reilly]

I switched it to use FragmentContainerView ....it doesn't crash now when I show that "screen" again but just does't render map

[Ian Lake]

Makes sense. Removing the parent view that hosts one or more Fragments (which I would assume would be the case when you go to your next screen and the AndroidView is no longer in the composition) doesn't do anything to the FragmentManager's state - the Fragment would still be in the resumed state, trucking along. Same is true in the non-Compose world

[Ian Lake]

(which is WAI and required to support cases such as ViewPager2 where they are controlling the placement and attachment of a Fragment's view with the overall hierarchy)

@John O'Reilly Hi I wanna use map and see your weblog, but seems that not woking. Main error is the way you used android view.

AndroidView(resId = R.layout.map_layout, modifier = Modifier.weight(0.4f)) {

[John O'Reilly]

@Mahdi that project is still using alpha04....perhaps something has changed since then. Will try and grab some time later and take a look. What error are you seeing btw?

[Mahdi]

Thanks John. In your method that part is not working any more.
I'm looking for new ways. If you had time please take look at this:

https://github.com/joreilly/galway-bus-android is the project that's still on alpha04.....but.....I think I updated that since that article, primarily based on what was in Crane app which it sounds like you've tried as well
