React Native WebStorm Emulator cannot start - error Failed to launch emulator. Reason: No emulators found as an output of `emulator -list-avds`

I'm new to WebStorm and React Native and I encountered an error while setting up my environment that appears unique compared to the other post I've seen.
Objective
I've set up a default project in WebStorm, my goal is to run that project on an Android emulator, I'm using a Windows PC.
What I've tried
I've set up a simple Debug configuration in WebStorm
I've also downloaded an Android Emulator thru Android Studio and I have it running on my computer.
Now when I click on run for my debug emulator I get the following error:
info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag.
Jetifier found 864 file(s) to forward-jetify. Using 4 workers...
info JS server already running.

Other Information
Here is a picture of my Path System variables:

adb is not on your %PATH%; make sure to add the folder where adb.exe is located (usually $ANDROID_HOME/platform-tools, where $ANDROID_HOME is your Android SDK install dir, usually C:\Users\Your.Name\AppData\Local\Android\sdk, you can run where adb command in Windows cmd console to find it) to %PATH% under System environment variables and then restart WebStorm.
You also need defining %ANDROID_SDK_ROOT% environment variable per suggestion in the error message

Just to add, windows environment variables are case sensitive and adding %LOCALAPPDATA%\Android\Sdk like the react-native website says will not work, you need to add %localappdata%\Android\Sdk

react-native can't find android sdk

I have gone through every similar question on here but can't find a solution. I am testing out react-native on my xubuntu 18.04 and I'm stuck on the last step of launching the app on my phone. I have installed android-sdk and it is located in /usr/lib/android-sdk,
I also see my device attached when I do adb devices
I have added the below inside the .bashrc file and have done $ source ~/.bashrc and restarted the terminal and tried running the app again
export ANDROID_HOME=/usr/lib/android-sdk
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/build-tools/24.0.0:$PATH
I keep getting:
FAILURE: Build failed with an exception.

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/getting-started.html
I also tried the local file approach with local.properties file and adding sdk..what am I doing wrong here?

Please check the version of the sdk installed and the version of the sdk in the gradle
It should be the same.
It worked for me when giving the same versions.

Android React Native build fail

I create the simple React Native Project.
Step 1.
C:>react-native init AwesomeProject
Step 2.
C:>cd AwesomeProject
Step 3.
C:>react-native run-android
After that I faced the following error.

Android sdk path in your enviroment is not correct.

Ionic app build issue

I am new to ionic. I have developed sample application ionic.
When I try to execute below command it gives gradle error.
$ ionic build android
Below is the build error:
Error: /home/myapp/platforms/android/gradlew: Command failed with exit code 1 Error output:
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred starting process 'Gradle build daemon'
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Gradle version is 3.3

Android SDK and Android Studio located in /usr/local/ folder
You will either have to move it to your home directory (that involves reinstall).
Or run ionic build commands with sudo
sudo ionic build android
You could technically change permissions of the specific sdk and studio folders but it is not advisable especially in /usr directory.

Unable to build Android using ionic

I am trying to setup Ionic framework for developing android apps on my mac but I am having some problems in building android apps.
I have followed following procedure for installing ionic :
Run: "sudo npm install -g cordova"
Run: "sudo npm install -g ionic"
Run: “android” then install the following packages
Tools: Andoird SDK Tools, Android SDK Platform-tools, Android SDK Build-tools
Android 4.4.2 (API 19)
Extras: Android Support Library
My .bash file is like this :
export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=${JAVA_HOME}/bin:$PATH
export PATH=${PATH}:~/Library/Android/sdk/tools:~/Library/Android/sdk/platform-tools
This is the error I am getting while building android app :
You have been opted out of telemetry. To change this, run: cordova telemetry on.
Running command: /Users/coderahul/sampleIonicApp/hooks/after_prepare/010_add_platform_class.js /Users/coderahul/sampleIonicApp

ANDROID_HOME=/Users/coderahul/Library/Android/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home

Please install Android target: "android-23".
Hint: Open the SDK manager by running: /Users/coderahul/Library/Android/sdk/tools/android
You will require:
1. "SDK Platform" for android-23
2. "Android SDK Platform-tools (latest)
3. "Android SDK Build-tools" (latest)

This happened to me just type this in your terminal "/Users/coderahul/Library/Android/sdk/tools/android" and proceed with the steps to download the sdk for android-23.
This happens because your device is using the higher version of OS than the sdk version
