By placing the command "react-native run-android with the phone simulator with Genymotion it does not execute me, I have configured the environment variables of the JDK several times and I still can not move forward.

It is a problem in the configuration of the environment variable JAVA_HOME that is apparently pointing to the JRE directory when it should point to the JDK, for example in my case it is:
C:\Program Files\Java\jdk1.8.0_151
This route is where you are: "tools.jar"
