Expected Behavior

The release build should not crash.

Actual Behavior

The debug build working fine.
The release build crashes on launch after displaying native splash screen.

@YogeshYo are you able to provide us a reproducible demo?

[YogeshYo]

@joshyhargreaves, Thanks for your reply.
What demo do you need on this? Please guide. I have attached screenshot.
The crash takes place as soon as we launch application even before appearing splash screen only in the release build both iOS & Android.
I tried on another system as well but the same result.
I also tried upgrading react-native & reinstalling node modules.
What may be the reason for such type of issue i.e only in release build & Void 0?
Do you need a package.json details?

[joshjhargreaves]

Ideally we’d have a project you’ve uploaded which exhibits this crash; maybe you can reproduce with your depdencies and a new project.

However, when I’ve seen crashes that happen on both iOS and Android at startup, it usually points to a problem that only occurs when building the jsbundle in release mode.

To test this theory, modify your JSCodeCodeLocation on Android or iOS to point to: http://localhost:8081/index.bundle?platform=ios&dev=false&minify=false and see if the stack trace is any more informative.

[YogeshYo]

@joshyhargreaves, I tried above for android
protected String getJSMainModuleName() {
return "http://localhost:8081/index.bundle?platform=android&dev=false&minify=false";
}
but no luck. if you want I can present you the demo.

[joshjhargreaves]

The actual point is finding the cause of the crash!

[YogeshYo]

@joshyhargreaves, With jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.bundle?platform=ios&dev=false&minify=false"];. I am able to get tha same message as i posted earlier.

[YogeshYo]

@joshyhargreaves, anything else I can try? Release build was working fine until last week. I tried a release build with removed lib added since then but same error on release build. "App crashes after splash screen on both Android & iOS"

[joshjhargreaves]

@yogesho, the thing I might suggest, is if you can keep your native dependencies, remove any application code that you don’t want to upload, and create a repro project, then that’s be easier for one of us to take a look.

[YogeshYo]

@joshyhargreaves, i have shared repository details to you at joshyhargreaves@gmail.com

[YogeshYo]

@joshyhargreaves, can you please look into this? I tried to reach you on Gmail. Thanks

[joshjhargreaves]

Hi Yogesh, I’m a bit caught up at work at the moment and I haven’t had the time to look, and it’s unlikely I will be able to tomorrow or over the weekend. Your best bet is to try and create a reproducible sample project that demonstrates this crash and upload this to the GitHub issue. Even if it means keeping your same native decencies, it’s just a lot easier for people to help you if they can try and find out the problem without downloading your production app. Thanks Josh

Hi @joshyhargreaves ,

I will do this still, I think if you have a chance to have at least one look then I am sure you can at least give me hint to move ahead on this. Believe me, I tried everything I can & now I am stuck.
It's already around 10 days so I am requesting you to have one look.

Thanks

HI @joshyhargreaves, reproducible demo added
https://github.com/Tradesmen/CRASH/tree/master.
I request you to remove "Need more information" badge.
Thanks

@YogeshYo I have similar issue and it start happening after upgrade to react-native 0.50.4. I'm told the cause could be a that a dependency violates things that became invalid in react 16.0.0.

[YogeshYo]

@testshallpass, I went line by line & found two culprits for this issue (i.e only in release build).

Platform.select({
"ios": () => StatusBar.setBarStyle("light-content"),
"android": () => StatusBar.setBackgroundColor("#263238")
})();
The second was #4831 for which I got a proper message in the crash log which helped me to fix.

Still, i think for the 1st; either the issue should be rectified in debug build or at least get a proper error message in the crash log.
