Run the following commands on the terminal, or save them inside one of these existing files on your system: ~/. bash_profile , ~/. profile or ~/. zshrc

export ANDROID_HOME=~/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools

Answer 2

Caio, a question, has the environment variable ANDROID_HOME set? If you do not know, run the command: echo $ANDROID_HOME for mac or linux. If you haven’t set the variable, set it by pointing to where your Android SDK is.

If the variable is set, do the following:
Open Genymotion > Settings > ADB > Check the box Use custom Android SDK tools > Select the folder that is set your ANDROID_HOME.
