Error JAVA_HOME is not set while it is set

When I try to run command:

    react-native run-android

I get this error:

Scanning folders for symlinks in /home/x/myApp/node_modules 
(10ms)
JS server already running.
Building and installing the app on the device (cd android && 
./gradlew installDebug)...

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.

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

JAVA_HOME is set correctly (I think)

java -version

and 

echo $JAVA_HOME

return correct results. Screenshot: 1 JAVA_HOME is set in /etc/environment /etc/profile /bashrc /bash_profile

I did source /bashrc etc too

Virtual device is connected too. I'm able to open this project in android-studio and generate apk

In linux you don't need to restart your PC, if you have ubuntu or a derivative the file that contains the PATH is in /etc/enviroment , check that file to see if JAVA_HOME is set there.

Aditionally, you might wanna use JDK8 , since JDK9 and 10 don't work well with react native.

Then close your session and login again

Make sure you have java installed

after that

if your path is wrong do this:

export | grep JAVA

THE RESULT: what java home is set to

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home

follow the path to see if the directories are correct i did this in my terminal:

open /Library

then i went to /Java/JavaVirturalMachines turns out I had the wrong "jdk1.8.0_202.jdk" folder, there was another number... 4. you can use this command to set java_home

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
