After initializing my project with react-native init AwesomeProject I try to run it in the simulator via react-native run-android
However I get the following error:
ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
error Failed to install the app. Make sure you have the Android development environment set up: https://facebook.github.io/react-native/docs/getting-started.html#android-development-environment.
Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081
However I followed the Getting Started Guide and the JAVA_HOME Evironmental Variable is set and C:\Program Files\Java\jdk1.8.0_221\bin is also in the Path var.
I am trying this on Windows 10 with the WSL bash.
I was able to fix this by creating a new project. The problem was that I run react-native init AwesomeProject from the WSL bash in windows. I could reproduce this.
When running the same init command in the command prompt it works.

Sometime we need to manually set the path (environment) of JAVA_JDK . Install latest JAVA JDK from official website. And set the path of jre and bin folder. After looking your directory C:\Program Files\Java\jdk1.8.0_131 I guess you are on windows , So I'm not sure how to set environment variable for windows but definitely you could get help from youtube.

Failed to open /qemu.conf, err: 2
What the wrong move that I did in this situation?
You can checkout the same question at this. Edit your environmental variable.
Go to User Variables and Edit the path and add %JAVA_HOME%\bin.
Now in your system variable environments: edit the path and click new and add this C:\Program Files\Java\jdk1.8.0_241\bin
Again in system variable environment click on the path and click on new add this line C:\Program Files (x86)\Common Files\Oracle\Java\javapath
Now save and restart your system. this would help you.
You need to setup the JAVA_HOME environment variable that will be called when running react native android build.
Setup guide for JAVA_HOME.

Anyone can tell what's the problem, after I've run "react-native run-android" command.
That question's solution is type following command in cmd for following:
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_144
