Crash on Android: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.view.View.getId()' on a null object reference

[BrandonWade]

Description

While upgrading an app to RN 0.80.1, I've encountered a crash on Android that only occurs in the new architecture. I can reliably reproduce it in that project, but am unable to share it as the code belongs to my employer. That project uses many libraries, but I've created a reproducer with just a few to help narrow down the cause. While I am able to reproduce it every time in the project I am upgrading, the reproducer triggers it often but not 100% of the time, so it might take many tries before it happens. I have seen this issue both in the Android emulator (for the project I'm upgrading as well as the reproducer) as well as on an actual device (for the project I'm upgrading only).

To run:

1. Install the dependencies with npm i
2. Start Metro with npm start
3. In a new terminal, run the app on Android using npm run android

I believe all of the following must be true for the crash to occur:

• The new architecture must be enabled
• There must be two TextInput components within a ScrollView
• You must type in the first TextInput
• The second TextInput must be focused before clicking submit
• The submit button must:
  1. Display a Toast using Toast.show (from the react-native-toast-message library)
  2. Attempt to navigate using navigation.popTo or navigation.replace. I have been unable to reproduce it with navigation.navigate (from the react-navigation libraries)

When the app crashes, the Metro logs show nothing other than the websocket disconnecting when the app closes. The stack trace with the exception is captured by Logcat. I've included a recording demonstrating the problem with Logcat in the background in case it is useful, and included the exact stack trace from that recording in this report.

Apologies if this is the wrong place to post this - I'm not totally sure if this is an issue with React Native, React Navigation, or React Native Toast Message as I required all 3 to reproduce this issue. I opted to put it here since I was only able to reproduce the problem with the new architecture enabled. I also searched for existing issues as well as any other users who encountered this but found nothing. If you require any additional information, please let me know. Additionally, if the problem lies with one of the other projects and I'll open an issue there.

Steps to reproduce

1. Focus the "Title" field, and type some text
2. Focus the "Description" field
3. Click the "Submit" button

Note that the crash doesn't occur 100% of the time, and might take many tries to reproduce.

Thanks for the report. I think that it might have something to do with a null check we forgot to add.

This is the line that is crashing. I believe that host.getChildAt(0) might be null.

@cortinico what do you think?

[cortinico]

This is already fixed in:

• Fix Custom Focus Ordering for FocusForwar, FocusBackwards and nested children #51575

Shipping in 0.81

[BrandonWade]

That's great to know, thank you. Is there any timeline for when this fix would make it into a stable release, either in a 0.80.X or 0.81.0 non-RC version?

[cipolleschi]

0.81 will be shipped mid august

[pierroo]

Hey @cipolleschi , I just wanted to make sure this was indeed fixed in 0.81 ?
Since I didn't find a mention of this issue in the changelog for 0.81 (unless I missed it)
Thank you!

Hey @cipolleschi , I just wanted to make sure this was indeed fixed in 0.81 ? Since I didn't find a mention of this issue in the changelog for 0.81 (unless I missed it) Thank you!

This fix landed in 0.81. It was not mentioned in the changelog because the commit was marked as internal: 2c04b54
