react-native-reanimated:androidJavadoc errors running react-native app on android devices

I'm not sure what I've changed, but I can no longer get my app running on android devices. Running npx react-native run-android --deviceId abcdefg123 results in the following errors:
info Done writing bundle output
info Done writing sourcemap output
info Copying 47 asset files

I've been going in circles for a day now, trying to figure it out but I keep coming back to this error. Any ideas what I've done wrong, or what to try next?
Update:
If I remove the --deviceId flag, the app will run on the android emulator just fine. And it also works if I plug in a Samsung device I have.
When I plug in another device (Mi Max 2), I'm now getting a different error - see this post
However, the react-native-reanimated:androidJavadoc error described above still persists for both devices when I attempt to target either of them directly with the deviceId flag.

I was able to solve this issue, by following the installation guide of React-native-reanimated.
First install :
yarn add react-native-reanimated#next
Turn on Hermes engine by editing android/app/build.gradle :
project.ext.react = [
enableHermes: true // <- here | clean and rebuild if changing
]
Plug Reanimated in MainApplication.java
import com.facebook.react.bridge.JSIModulePackage; // <- add
import com.swmansion.reanimated.ReanimatedJSIModulePackage; // <- add
...
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
...
#Override
protected String getJSMainModuleName() {
return "index";
}
#Override
protected JSIModulePackage getJSIModulePackage() {
return new ReanimatedJSIModulePackage(); // <- add
}
};
...
Then clean your project and Build using ./gradlew clean and ./gradlew build in android folder of your project.

Flutter packages path not found

I've installed Flutter without Android Studio following these two tutorials: https://medium.com/#quicky316/install-flutter-sdk-on-windows-without-android-studio-102fdf567ce4 and https://dev.to/ejgamer21/install-flutter-without-android-studio-58bi.
I have connected my phone with USB debugging enabled and I've run flutter doctor: everything seems to be fine (although I haven't configured an IDE yet). Then I've tried to run the "Hello world" example that comes with Flutter using flutter run in the hello_world directory, but I get this error:

("Impossibile trovare il percorso specificato" means "Couldn't find the specified path")
Something seems to be wrong with the path for the packages, I have located the required file at C:\Users\mpepi\Android\flutter\packages\flutter\lib which of course is different from the one in the first line. I have set all environment variables as the tutorials explain, what am I missing?

Delete in the .vscode file. Restart the flutter application of visual studio code and run 'Flutter run'. It worked for me.

You could try to set "File Transfer" mode on your phone, it usually is on the notification bar if the phone is conected

For some cases I've also faced the similar issue. This problem is likely to arise when flutter doesn't get the packages. It wasn't even getting the material package, like your widget package.
Fix: Go to pubspec.yaml file. Make sure your internet connection is on and working. If you're developing in vscode you'll find buttons at top-right corner. Click Get Packages and wait until flutter downloads the packages.
If you don't find those buttons, then from the command line navigate to the project folder and run flutter pub get or flutter packages get.

React-native: RNSvgPackage() error

So I'm getting an error (at the bottom) that's most likely caused by me trying uninstalling react-native-pathjs-charts. The problem below only exists on android and not on ios.
Error:

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

Also have in mind that the package was changed from:
import com.horcrux.svg.RNSvgPackage;
to
import com.horcrux.svg.SvgPackage;
so you have to change from new RNSvgPackage() to new SvgPackage()
hope it helps!

I guess you did not unlink before uninstalling the module. Install again, unlink and then uninstall the module.
npm install react-native-pathjs-charts --save
react-native unlink react-native-svg
npm remove react-native-pathjs-charts --save

Run with yarn add package_name is helped me.

Cordova:Unable to build project with corodva-plugin-calendar

I'm developing the cordova application, in which I want to have some kind of booking functionality through calendar. So for that, I installed very famous EddyVerbruggen/Calendar-PhoneGap-Plugin plugin.
But while building the project, it's throwing following error
/home/admin/Desktop/myApp/platforms/android/src/nl/xservices/plugins/Calendar.java:148: error: cannot find symbol

I also gone through following threads..but still no help
Android M (6) compatibility
Issue related to the new Cordova version CLI >5
My Environment
Cordova-CLI : 6.1.1

So, what should I do to resolve this issue?

I had the same problem after updating my plugins. To save time, I just used an older version of the plugin.
ionic plugin add cordova-plugin-calendar#4.4.4

€ sign in method name fails test case using Gradle

I am using windows 8 as operating system.
I have a test method in Robolectric which has € in method name. When I run the test using Gradle wrapper in Android studio with gradlew test command,

I have researched about it and found out it could be related to encoding to UTF-8
It seems I need to use it without BOM:
Illegal Character when trying to compile java code
Android Project Compiled with Ant doesn't compile, Illegal Character Error
But I do not know how to fix it in a proper way exactly. Do you have any suggestion to fix in Android studio terminal?
Addenda: A friend of mine who uses Linux has no problem to run the test.

The proper way to fix this would be to remove the character from the method name.
I dont know of any actual limitations - you mentioned it works on a Linux machine - but it is terrible practice. Just spell out the word
