Description

Hi,

In Android the app randomly crashing with the below error. Got this in firebase crashlytics dashboard and there is no log to debug and reproduce. and We see this crash mostly happens on Samsung devices.

Any solution??

Version

Output of npx react-native info

No response

Steps to reproduce

Got it in Firebase Crashlytics.

Snack, code example, screenshot, or link to a repository

No response

[dmytrorykun]

Hello @nmanvitha , TypeError: null is not an object (evaluating 'U.networkType.value') makes me think that this may be not a React Native issue. To help us investigate, please do the following:

• Provide a reproducer with clear steps to reproduce. This way we can be sure that it is actually a React Native issue.
• Provide a symbolicated crash log.
• Provide proper npx react-native info output. The text you've posted is not it.

[github-actions[bot]]

:warning:	Missing Environment Information
:information_source:	Your issue may be missing information about your development environment. You can obtain the missing information by running react-native info in a console.

[github-actions[bot]]

:warning:	Missing Reproducible Example
:information_source:	It looks like your issue is missing a reproducible example. Please provide a Snack or a repository that demonstrates the issue you are reporting in a minimal, complete, and reproducible manner.

[nmanvitha]

This issue i got in firebase crashlytics. There is no log and I'm unable to reproduce the crash.

[dmytrorykun]

@nmanvitha unfortunately without those details we cannot help. It is important for us to be sure that we are working on actual React Native issues here.

[RowlandOti]

I am also facing this issue - and just like you it happens in a way I can't reproduce, however, this is a log am seeing in my diagnostics.

[santitopo]

Same thing here. We are seeing crashes reported in the Play Store crashes & ANR console. This is all we get as the stack trace (I realize it might not be the same network error originally reported in this issue):

[n-kulic]

@dunicn @rezq2009 can you paste your app dependencies? I want too see if it's related to some package

<details>
<summary>package.json dependencies</summary>

[paste dependencies from package.json here]  
</details>

Here's mine:

[rezq2009]

hi @n-kulic

The dependencie that I use from your list is only react-native-permissions

I don't think this is the package related problem.

[hassey13]

I have the same issue but in getting deeper in the logs I found the actual error, which is unrelated to react native. If you have this I would recommend a better crash reporting lib or on the device to use adb get the logs and get the error.

[monokaijs]

Seems like problem was caused by ProGuard. You can try disabling it by modifying your app's build.gradle (which is located in ./android/app/build.gradle) Set:

minifyEnabled false
useProguard false

So your buildTypes configuration section looks like this:

buildTypes {
    debug {
        signingConfig signingConfigs.debug
    }
    release {
        // disable proguard
        minifyEnabled false
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
    }
}

Goodluck.

[jeffinhk]

Not the best answer out here, but in my case I increased the target SDK and maximum SDK to 33 (latest).

Thanks . i am trying it out. crossing my fingers that its a fix . i'll let you know how it goes .

[monokaijs]

Don't use useProguard false if you're using newer versions of React otherwise it will prevent you from building application. A clean build is also required.

[k3nnet]

disabling Proguard or bumping up the target SDK doesn't seem to resolve my issue @monokaijs @jeffinhk . my app is still crashing on start up after install . although now i am getting a different error . i am using expo managed workflow and disabling proguard in app.json like so "enableProguardInReleaseBuilds":false , now i am getting this error java_vm_ext.cc:534] JNI DETECTED ERROR IN APPLICATION: java_object == null

[HyopeR]

I'm having the same problem. And I can't reproduce.

[vaish8529]

Got similar issue. Any solution?
