[Bug] Android : Java.Lang.IllegalStateException: Fragment FragmentContainer{7f20e26} (f17e4f2b-a95f-41fd-ade2-368ecc2dd0b4) id=0x2 android:switcher:2:-1519590384} does not have a view
Description
I have a TabbedPage which is using tabs on the bottom. Each page was a MasterDetails page and since I migrated them to Flyout Page I have this exception making my app crash : Java.Lang.IllegalStateException: Fragment FragmentContainer{7f20e26} (f17e4f2b-a95f-41fd-ade2-368ecc2dd0b4) id=0x2 android:switcher:2:-1519590384} does not have a view
Steps to Reproduce
- Use a Tabbed Page as the main page (not shell).
- Create some FlyoutPage having a NavigationPage as the details and a ContentPage as the flyout.
- Launch the app
- Use some other apps (especially memory consuming one)
- Launch again your app from the "main icon"
Expected Behavior
The app is displayed.
Actual Behavior
This exception makes the app crash :
Java.Lang.IllegalStateException: Fragment FragmentContainer{7f20e26} (f17e4f2b-a95f-41fd-ade2-368ecc2dd0b4) id=0x2 android:switcher:2:-1519590384} does not have a view

@jonathanantoine Can you attach a small repro of this crash? I'm not seeing anything in the stack trace that gives me any indication of what might be wrong here
I'm seeing similar crash reports in appcenter, the app doesn't use the flyout page, and it seems like it's crashing on startup, but I was not able to reproduce it, using xamarin forms 5.0.0.2012

@PureWeen Crash reproduces after changing font size in OS settings and switching back to the app.
XF 4.8 works OK - no crash, app relaunched. XF 5.0 crashes
Not sure if this is the reason, but JNI-used constructor is missing from FlyoutPageContainer
@PureWeen @melimion I did some investigation and it appears it works fine with XF 5.0.0.2012 and FlyoutPage.
Now I am supsecting one of the latest Xamarin.AndroidX nuget package to be the culprit. I am now upgrading them one by one to detect which one is causing the issue.
Here is my working AndroidX packages versions, updating one of them to the last makes the bug to be here :
<PackageReference Include="Xamarin.AndroidX.Fragment" Version="1.2.5.4"/>
@melimion can you tell me if you have one in a higher version than this ?
Edit - I am trying to update them one by one to find the culprit(s). Here is the list of excluded one :

@jonathanantoine I have all packages updated to latest version.
Downgrading to versions that you specified fixed the problem.
Do you need to reference all those AndroidX packages? Can you just remove them all and just use what transiently comes in with XF?
@PureWeen yes, it's asked by the Android x migration tools and build failed if not added.
If I run the "Migrate to Android X tool" they are all added back so I can't think it's a good idea to remove them.
I'm seeing this issue after upgrading to the latest packages as well. I upgraded both Xamarin.Forms and all the Xamarin.AndroidX packages, so I'm not sure which of them caused it.
I'm using a FlyoutPage, but no tabs.
If I don't upgrade Xamarin.AndroidX.Fragment and stay to the Version 1.2.5.4, the crash do not seems to happen. I think we have our culprit.
Can someone attach a small sample project reproducing the issue so that we can investigate further? I've tried and unfortunately have been unable to reproduce the issue myself :/

@rachelkang @jonathanantoine I'm still getting the crashes in 1.2.5.4. Note: I'm using Shell. There are other issues found with this package as well: https://github.com/xamarin/Xamarin.Forms/issues/13843

@rachelkang here's a repo: https://github.com/Jakar510/DebugXamarinAndroidX/tree/master
Got this issue also randomly with a TabbedPage, no navigation page inside, no flyout. This happens often when the app is idle/backgrounded for a long time and re opening it. Never had the chance to reproduce on debug builds, only release ones.
XF 5.0.0.2012 Target Framework : 11
I was able to reproduce the issue by :
- Enabling the setting "Don't keep activities"
- Minimize the application
- Open the application from recent apps menu
I've reverted the recent AndroidX updates that I've installed in order to prevent the error to happen.
@ducmerida can you share which androidX packages you downgraded (fragment I guess ?), but from which version to which version . Cause I don't have a direct reference to fragment, I want to be sure its the one that causes the issue
@vincentcastagna you can add a direct reference to Android.X.Fragment in it's "1.2.5.4" version. It should do the job.
@vincentcastagna you can add a direct reference to Android.X.Fragment in it's "1.2.5.4" version. It should do the job. This fixed it for me.
Based on the conversations here it sounds like this PR should resolve
https://github.com/xamarin/Xamarin.Forms/pull/14101
If you can test the nugets here that would be helpful
https://github.com/xamarin/Xamarin.Forms/issues/13843#issuecomment-819121845
@PureWeen it does not seems to fix the issue. I think you can reopen it :(
@jonathanantoine what version of Android Fragment works for you?
If you update to the latest version https://www.nuget.org/packages/Xamarin.AndroidX.Fragment/
does that work for you?
I have the same problem. Xamarin.Forms 5.0.0.2012 and Xamarin.AndroidX.Fragment 1.3.2 installed, also using TabbedPage
@jonathanantoine what version of Android Fragment works for you?
If you update to the latest version https://www.nuget.org/packages/Xamarin.AndroidX.Fragment/
does that work for you?
@PureWeen nope, with the latest Xamarin.AndroidX.Fragment can reproduce, app crashes after I reopen it from multitask
The version 1.2.5.4 crashes for me. The latest that does not crash is "1.2.5.3"
Hi @PureWeen after update to the latest version i get similar exception. But only sometimes:

We also get this on anything that triggers an activity restart (plugging in a USB keyboard or changing the font size while the app is backgrounded for example).
Downgrading the androidx fragment package to 1.2.5.5 solved out issue.
1.2.5.5 solves the problem any version above this is crashing. anyone has proguard settings for this library? should this be just fine?
-keep public class androidx.fragment .** { *; }
I also have the same bug in android I have the latest version of XF:
android.runtime.JavaProxyThrowable
crc643f46942d9dd1fff9.FormsAppCompatActivity.n_onStart
This is what Google /ARN says
any solution???
This is a serious error in production, according to Google/ARN it has occurred in Xiaomi and OnePlus with Android 10 and 11
@jsuarezruiz why unverified ? You have a repro project ? @jfversluis this is for this reason I ask you if I were not doing a repro for nothing...😔
@jonathanantoine I don't understand. Javier removed the unverified label. I have seen your reproduction and I will get to it, but I haven't had the time yet. Your effort has not been for nothing, don't worry.
This bug seems to have disappeared in the newest versions, at least for me (but I'm using a FlyoutPage, not a TabPage, so I cannot speak for everybody in here).
I'm currently on Xamarin.Forms.5.0.0.2125 and Xamarin.AndroidX.Fragment.1.3.6.3, and haven't seen this crash since I upgraded the NuGet packages 10 days ago.
