I tried generating logs and searched on internet the errors i was getting on logs but found nothing

this error is caused by the absence of the index.android.bundle file in the ./android/app/src/main/assets directory
First step:
Create the assets folder if it does not exist in the android/app/src/main/ directory
Second step:
Run the following command line:
react-native bundle --platform android --dev false --entry-file index.js --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest ./android/app/src/main/res/
Step three:
Compile the application in release mode

How to fix React native app stopped working on android

i added firebase to my react native project and it's stopped running on my emulator. I've had this issue with firebase & react-native some years back, don't know what the fix was.
Running adb logcat displays this

Fixed it
According to the stacktrace, it was an issue with react-native-webrtc

Flutter crash after open apps

I usually build my mobile apps using build service from codemagic.com. During this week i didnt change anything of my code except build number.
Today I got my mobile phone crash after new AppBundle Compile with below error stack from firebase console.
Fatal Exception: java.lang.NoSuchMethodError

This crash occurs this week (last week was okay), this means There's something update on the 3rd party plugin library or from flutter, but I don't know which plugin causes this crash because I didn't change anything of my code.

any idea?

Could you try updating your firebase packages dependencies?

Flutter app crashes at startup are mainly caused by the any Package dependency issue
causing error can be debug via following command inside project folder into terminal
adb logcat
in your case 08-17 11:18:42.282 12595 12600 I zygote64: Increasing code cache capacity to 128KB 08-17 11:18:42.283 12595 12595 I CrashlyticsInitProvider: CrashlyticsInitProvider initialization successful 08-17 11:18:42.285 12595 12595 D AndroidRuntime: Shutting down VM
it seems crashlytics error
check if you have applied required dependency in android/app/build.gradle
as shown in picture
apply plugin: 'io.fabric'
adb logcat can provide the detail for exact error causing issue

project build.gradle
Whether androidx.core version is specified
Similar to the following
rootProject.allprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'androidx.core') {
details.useVersion "1.0.1"
}
}
}
}
If so, delete it

I had a similar issue with codemagic this week, but when I built locally and pushed to Google Play Console/App Store Connect the app runs successfully. Maybe an issue coming from codemagic?

Release application always crashing on splash screen

I'm facing an issue with React Native release builds. Either on iPhone or Android, my application works fine in debug mode, but after building with release configuration, the app always crashes on the splash screen.
On Android, I'm getting an OutOfMemory in the log triggered by WebSocketReader.java. Here is the Android log :

Does someone face a similar issue?

Try adding android:largeHeap="true" to your manifest under application:
Ex. <application android:label="YourApp" android:largeHeap="true"></application>

Found solution. The error was triggered because of the static image used in the application were too big.
See https://facebook.github.io/react-native/docs/images for more explanations.

Xamarin: Couldn't find "libmonodroid.so" emulator error

I've been getting this problem for a couple days and haven't found a solution yet.
I've been using an Android 7.0 ARM (armeabi-v7a) image for my emulator. Because it's so painfully slow, I've been trying to use Android 7.0 Intel Atom (x86_64) with HAXM but I get the following error when opening the app.

So i know it can't find this lib, but I don't know why it can't find this lib and I don't know how to fix it.
I've tried uninstalling the app, cleaning the solution, and rebuilding.
I've tried the 6.0 as well as 7.1.1 system images.
I haven't tried reinstalling xamarin or anything else because that would take the rest of the day on the network I have available to me.
Why doesn't libmonodroid.so exist and how do I fix it?
EDIT
x86_64 is enabled. Here is a screenshot of my device and the advanced android options.
AVD Settings-
Build Options-

I found a solution!
Disable ever ABI except x86_64.
I don't know yet which ABI causes the conflict. I think maybe X86. Because he always deployed a MonoRuntime...

Enable the x86_64 ABI in your Android Build Advance options:

Removing everything except x86 and x86_x64 will disable debugging on physical device.
The correct solution is to remove arm64-v8a and it will work alright.

Recently installed Xamarin and ran into the same issue, found the error in the Android Device Log (Visual Studio: Tools/Android/Device Log...) and this solution did resolve the issue. I went one step further and narrowed down the issue (at least in my case) to the need to remove supported architecture: armeabi. None of the other supported architectures caused the issue. I'm running Xamarin for Visual Studio 4.2.2.11, with Android 7.1.1 under the Android Emulator using Google APIs Intel Atom (x86_64) and Google's Nexus 5 device.

On, Visual Studio for Mac (8.7.1) this issue came up recently and there is an installation package for the Xamarin.Android SDK has been given in the GitHub issue.
Please check: https://github.com/xamarin/xamarin-android/issues/4983

As mentioned here, it started happening again and is fixed in the latest update of Visual Studio. So just check for updates and then install them.
