ExpoKit 27 crash at start

Expo SDK
1

I’m trying to migrate from ExpoKit 26 to 27 but when I test the app on my GenyMotion Emulator I got a “Unfortunately, ‘appName’ has stopped.”

I succefuly upgraded from ExpoKit 25 to 26 in the past, it seems something is wrong this time…

So far, I’ve tried two ways to upgrade:

  1. from a working ExpoKit 26 project:
  1. starting a new Expo SDK 27 Project
  • create a new expo project with the XDE Client
  • copy and past src folders, assets folders
  • complete app.json and package.json to match the previous project.
  • npm install
  • exp detach
  • exp start
  • build in Android Studio and running app.

Both ways lead to the same error. Is there something I missed for the 27.0.0 release?

Here is what I get when running adb logcat

I’ve completed the upgrade for iOS (same project) and it works like a charm.
It seems to be Android related, maybe something is wrong in my MainActivity or maybe I missed somthing somewhere making the app crashing at start on Android…
Any thought?

  • I’ve started a project from scratch using exp init
  • Copy and past sources from my Expokit 26 project.
  • changed App.js / app.json and package.json to match with the libs used and src folder.

From here the app run as it should using exp start and then exp android
Then I detached exp detach and everything compiles.
When lauching the app, it crashed with the same error message.

I’m using 2 lib that need to be linked react-native-fs and react-native-iap.
And even if I don’t link it, the app crashes.

Weird enough I did the same without incorporating my project code:

  • started a project from scratch using exp init
  • changed nothing
  • exp detach
  • run from Android Studio
    and I got the same result: App Crashes at start

In all case i get this error in the console log (where I get exp log): [exp] Metro Bundler failed to start. (code: EPERM)

Hi @alanlanglois! In the future please only post one issue or forum post, it’s difficult to go between the two to figure out what’s going on.

The [exp] Metro Bundler failed to start. (code: EPERM) seems important. It looks like there are a bunch of different solutions that people have tried for that: Metro Bundler failed to start EPERM - Google Search

The stack trace from android suggests that it doesn’t know about the development url. What is in DetachBuildConstants.DEVELOPMENT_URL? It should point to the url printed out by exp start.

Hi @jesse thanks for your help!
The build DEVELOPMENT URL doesn’t seems to be right:
public static final String DEVELOPMENT_URL = "";

It also says: // This file is auto-generated. Please don't rename!
Sounds like it doesn’t auto-generate this var.

I’ve tried anyway and rename this var with another address than the one exactly given in exp start but this one:
exp31805e2108a944619[…]e038://192.168.1.45:19000
rather than this one:
expb7f249fd277[…]2af969157b270://nw-kks.alanlanglois.msfs27.exp.direct:80
PLUS I removed the realtime and cloud firewall to avoid the EPERM error.
and it worked!

I’m not sure why this development URL is not set automatically, but it was definitely the cause of the crash.

Ok I’m glad you figured out the EPERM error.

Sorry that the file isn’t being auto generated. Can you try running exp prepare-detached-build in the project directory and see if it works? It should autogenerate that file. That command is supposed to be ran as a pre-build script when you build the Android project.

Hi @jesse

It changes this variable to DEVELOPMENT_URL = “exp31805e210[…]df4e0bb248e038://localhost:80”
I guess it works even if before it wasn’t localhost but my ip (which should result to the same).
Thanks for the tips, is this referenced in the doc?

Ok, I’m not really sure why that script wasn’t being called when you tried building the app. We don’t reference in the doc because it’s supposed to happen automatically, but it would be good for us to add some steps to debug.

Anyone got any solution ? I am getting the same issue.
I got this in my cli console

..............
:app:installDevDebug
Installing APK 'app-dev-debug.apk' on 'SM-G610F - 7.0' for app:devDebug
Installed on 1 device.

BUILD SUCCESSFUL

Total time: 3 mins 37.821 secs
Starting: Intent { cmp=host.exp.exponent/.LauncherActivity launchParam=MultiScreenLaunchParams { mDisplayId=0 mBaseDisplayId=0 mFlags=0 } }

But when I try to run the app in my device I got the popup “Sample Expo App has stopped … Close app”
Then it got closed.

@anil1712 did you try this?
