Standalone Android app sometimes crashes on app load

Expo SDK
1

Hello all,

Once again, a huge thank you to the Expo team!

I sometimes experience a fatal crash on startup from background on my standalone Android app. Sometimes it fails with an Expo screen like this:

Screenshot_20171019-112637
Screenshot_20171019-1126371440×2560 60.6 KB

and on other occasions, it shows the dreaded “ has stopped working”. When refreshing/restarting the app, it works fine again.

I’ve hooked up my app to Sentry, but I don’t get any useful information on the crash, just a pointer to a linenumber in the minified app bundle.

I’ve tried doing adb logcat ASAP after a crash, and have tried to filter the output to what makes sense for React Native/Expo to the following output:

Once the app is running, it runs great and smooth, but this is a class A deterrent for new users. I’ve only experienced it on my own phone, a Nexus 6P running 8.0, and cannot replicate on my collegue’s Pixel (also 8.0), so it might be something related to hardware/memory.

Any pointers or help would be much appreciated :slight_smile: Thanks!

Maybe related Github issue?

https://github.com/facebook/react-native/issues/16126

Our app is running SDK20 (RN 0.47)

I will try to upgrade to SDK21 and see if it helps, but if it’s the same issue I might have to wait for SDK22 (which I’m hoping is based off 0.49?).

Any chance of an ETA for SDK22?

3

Kept searching, tried random search for Expo SDK 22 - and apparently, the update was posted 16 hours before I wrote this :slight_smile:

I’ll try upgrading and see if it helps and get back with my results.

4

We think this is fixed in SDK 22. Let us know if you run into it again!

5

I have the same problem, even with SDK 22…

https://github.com/expo/expo/issues/779

6

Ok we fixed another issue with this for the SDK 23 release. Sorry this took so long. Hopefully this time it will work in all cases.

7

Thanks for getting back to this thread with an update. When can we expect SDK23? Because the app still crashes on startup sometimes on Android, with the following screen:

Screenshot_20171114-192605
Screenshot_20171114-1926051440×2560 63 KB

Other times it just crashes with “[App] has stopped” - I managed to get a adb logcat dump from one of these as well:

https://pastebin.com/eAP2aTrK

I don’t know what the problem is. It seems there’s trouble adding a view, and that another version of the native library was expected. Is this what you think will be fixed on SDK23, or am I facing a separate issue @jesse

8

That specific issue probably won’t be fixed by SDK 23, which is coming soon (we release ~monthly, give or take a week). It looks like an issue with React Native.

9

Which issue is the one that will be fixed in SDK23? :slight_smile:

10

Anything to do with Views / tags is unchanged. The fix was for “EOFs” related to bundle loading.

11

I misspoke - we also fixed a bug to do with View tags after resuming the app after some time. So the bug you encountered might be fixed – we just released SDK 23 today if you would like to try it out soon.

12

Thanks again.

I’ve been doing some research, too, and have found clues pointing to the use of LayoutAnimation maybe being the culprit. I’m not using it in my own codebase, but was thinking you might in Expo, perhaps within the AppLoading/Splash API/components?

For example this: https://github.com/facebook/react-native/issues/13984

I’ll try upgrading to SDK23 as soon as I can, but can you confirm/deny the above in the meantime? Can you link me the PR with the fix you mention about view tags when resuming?

Thanks :slight_smile:

13

I’ve been testing with SDK23 for a while, and it seems to have fixed the problems I had with startup on Android. Whether it’s Expo’s changes or the updates to RN is unknown.

Thanks for your hard work :slight_smile:

Good to hear that @jhalborg!
