React-native-webview: net::ERR_FAILED

Bug description:
The first time I open my app the website loads correctly in the WebView. Then I go to the homescreen and after a while I return to the app and gets the following error:
Website not available
The website at https://www.example.com?param=value could not be loaded because:
net::ERR_FAILED
Has anyone seen this error before?
Here is some logs from Android Studio that may or my not be related/useful.

To Reproduce:
I have only been able to reproduce this error in release - not in debug. This error happens after loading the app the first time, then leaving it and return to the app after a few hours.
Maybe it is related to cache.
The problem persist when I force quit the app. If I reinstall the app it is working for a while.
Expected behavior:
Website should fully load.
Screenshots/Videos:
Environment:
- OS: Android (Huawei P20 Pro and multiple other Android phones)
- OS version: Android 8
- react-native version: 59.3
- react-native-webview version: 5.6.2

I found a fix for this issue!
It looks like a broken service worker stalled the website.
I solved it by using the injectedJavascript prop in my WebView to inject the following lines of code:
navigator.serviceWorker.getRegistrations().then(function(registrations) {
for (let registration of registrations) {
registration.unregister();
}
});
It is a bug in Google Chrome 75.

My app restarted itself, log shows ChimeraModuleLdr: Module config changed, forcing restart due to module

I was testing my app and I saw it restart itself, was really weird. I looked and looked on the logs and I couldn't find anything odd except for this line ChimeraModuleLdr: Module config changed, forcing restart due to module. This is on a Pixel XL with Oreo.
Here are the last few lines of the log and the start up of the app after it was killed.

10-18 22:49:31.641 13717 13717 I MultiDex: VM has multidex support, MultiDex support library is disabled.
Any idea about what triggered this?

It seems that the ChimeraModule (or Dynamite) is the dynamic module loading system used by the Google Play Services (more details here).
I guess that, if your app is using a specific module from the Google Play Services, when that specific module is updated your app is restarted as well.

Adding to what #bonnyz already said, I fixed it by removing all references to the libraries updated by the module, in my case the android vision library.

Adding further,
In context of Xamarin Forms project, the error you describe was caused by the Xamarin.Forms.GoogleMaps V4 package. reverting to V3.x.x solved the problem for me.

NativeLibraryUtils: java.lang.UnsatisfiedLinkError: dlopen failed: 32-bit instead of 64-bit

I got this error when I deploy my Android APK onto a device. The same error is reported by the Google Play Pre-launch report:

There are some others with the same problem, but they are often related to Swift Android development. For instance, a similar (the same?) issue has been reported here: “dlopen failed: is 32-bit instead of 64-bit” in tests only. I am on Xamarin. The error makes no sense to me nor does anything related to what I am reading.
I tried all sorts of solutions such as, but not limited to:
different linker options (None, SDK only etc.)
recompile of all custom assemblies
clean builds, forced NuGet package download etc.
different supported ABI settings
If I run the code in debug mode on my emulator, everything is fine. The version built in release mode via VSTS and deployed onto Google Play doesn't work.
Any tip, hint and wild guess will be appreciated.

Google Mobile Vision library not downloading

I am trying to implement the Google Mobile Vision TextRecogniser API into my app, to read text off a given Image. When I try to use the feature, I get this error:
W/DynamiteModule: Local module descriptor class for com.google.android.gms.vision.dynamite not found.

I/Vision: Loading libocr library

Meaning, I believe, that the library wasnt downloaded to the phone.
I have troubleshooted for common error sources, including missing internet connection, lack of memory, missing dependencies, rebooting the phone, updating Google play services, waiting a while etc. Google repository and Play services are also updated in Android studio.
Yet, I still get the same error, even when trying my App on different devices.

I believe that the download is performed by the Google Play Service App. The Libraries are downloaded as a zip file in the folder
/data/data/com.google.android.gms/cache/downloadservice
and are extracted to
/data/data/com.google.android.gms/files/com.google.android.gms.vision
and our app always check for the library in path
06-02 22:43:53.379 30258-30419/pzy64.searchbot I/Vision: Loading library libocr.so
which shows the error if the files are absent

otherwise

After download,
In my case (ARM) the folder size of
/data/data/com.google.android.gms/files/com.google.android.gms.vision
is around 5MB.(So the file downloaded is less than this size, The size may vary for different architecture .It took more time to download in my Asus Phone (x86)).

The app i'm working on

I do "Clear Data" of the Google Play Service app and it works!

I think you missed out adding the "meta-data" tag in manifest file of your application. This meta-data tag tells your application to download and integrate the library to your application. Try adding a meta-data tag in your "application" tag above "activity" tag in the manifest file. See below:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version"/>
<meta-data android:name="com.google.android.gms.vision.DEPENDENCIES" android:value="barcode"/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
This might solve your issue.

I don't know if I am too late, but guys, after hours of challenges for me the problem was solved by Updating Google Play Services to version (12.6.85). I restarted the device and guess what? The app worked fine.
For updating this Google play service these instructions.

after some trials I figured out that in the gradle file you have to add these lines, too:
compile 'com.android.support:support-v4:24+'
compile 'com.android.support:design:24+'
So apart from this one
compile 'com.google.android.gms:play-services-vision:10.2.1'
the other two lines are important, too.

I had the exact same problem. As soon as I logged in to Google Play service then it downloaded and the barcode detector worked in the camera.

Android app becomes slow after adding Firebase Analytics and Crash Reporting

Before adding firebase analytics my app worked really fast. It has a lot of request which are sequential.
However, as soon as I added firebase analytics my app's internet requests froze and I got a lot of logs which consume time for no purpose.
W/System: ClassLoader referenced unknown path: /data/app/my.project.-1/lib/arm64
W/art: Verification of void my.project.App.<init>() took 133.425ms
D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.
D/FirebaseApp: Initialized class com.google.firebase.iid.FirebaseInstanceId.
V/GoogleSignatureVerifier: com.google.android.gms signature not valid. Found: <Some big sequence of characters>
I/FA: Tag Manager is not found and thus will not be used

I/DynamiteModule: Considering local module com.google.android.gms.crash:0 and remote module com.google.android.gms.crash:2
D/ChimeraFileApk: Primary ABI of requesting process is arm64-v8a
D/FirebaseCrashReceiverServiceImpl: onCreate
I/DynamiteModule: Selected remote version of com.google.android.gms.flags, version >= 1
This is quite important, because I wait about 5-6 seconds until my own requests start to execute.
