When using a Frame inside a BottomSheet, the app crashes while trying to open that BottomSheet on Android.

<!-- bottomsheet -->
<GridLayout rows="*" iosIgnoreSafeArea="true" height="500">
    <Frame id="frameMenu" defaultPage="menu-page" actionBarVisibility="never"/>
</GridLayout>

<!-- menu-page -->
<Page actionBarHidden="true">
    <StackLayout>
        <Button text="Button 1" id="1" tap="onButtonTap"/>
        <Button text="Button 2" id="2" tap="onButtonTap"/>
        <Button text="Button 3" id="3" tap="onButtonTap"/>
        <Button text="Button 4" id="4" tap="onButtonTap"/>
    </StackLayout>
</Page>

Crash log:

While researching I came across this issue: https://github.com/NativeScript/NativeScript/issues/8126 It's about the same error message so it is possible that this issue here is not caused by the bottom-sheet alone. However, the other issue is about suspending and resuming the app which is not the case here, so it might have a different cause.

Which platform(s) does your issue occur on?

• Android
• tested on 6, 9, 10, 11
• emulator and device

Please, provide the following version numbers that your issue occurs with:

• CLI: 7.1.2
• Cross-platform modules: @nativescript/core 7.1.4
• Runtime(s): @nativescript/android 7.0.1 and @nativescript/ios 7.1.1
• Plugin(s): @nativescript-community/ui-material-bottomsheet 5.2.3

Please, tell us how to recreate the issue in as much detail as possible.

Open the sample app provided above, tap the button to open the bottom sheet -> Crash (Anroid)

Is there any code involved?

@felixkrautschuk still happening?

[felixkrautschuk]

@farfromrefug I updated all dependencies (nativescript/core 7.3.0, nativescript/android 7.0.1 and the bottomsheet plugin 5.2.31) and yes, it is still happening the same way.

Updated project: NSBottomSheetNS7.zip

I also tried updating NS 8 in combination with the bottomsheet 5.2.31, but no difference.

@felixkrautschuk it seems to be an issue with N. Something is really wrong with the way N handles fragment managers. It creates a lot of issues all over the place. I cant do much right now as it would requires a lot of time/work to correctly fix this. For now i would suggest not to use a frame inside a bottomsheet. Which btw is not a good ui design. There should be no navigation inside a bottomsheet

[felixkrautschuk]

@farfromrefug thanks for your feedback.

I have already thought of something like that, because I firstly came across this kind of crash in an app without using the bottomsheet. But the sample app containing the bottomsheet was the only app where I could reproduce this crash so I decided to create the issue thread here instead of the core repo :)

[farfromrefug]

@felixkrautschuk yes i understand. Maybe it would be a good thing then to raise ald link this issue in the N one? We now have a reproducible example

[farfromrefug]

@felixkrautschuk i am now thinking it is a bug on the plugin side. The reason is that in N it works for modal views which work the same way as the bottomsheet on android
