React Native make android app load in genymotion - react-native

Question

I am trying to build an android app in react native. I have followed the official guidelines and downloaded genymotion and created a new project in react native. How do I open my project in genymotion?
I am getting the following error in my terminal
FAILURE: Build failed with an exception.
Where:
Build file '/Users/adamkatz/Projects/testAndroid/android/app/build.gradle' line: 69
What went wrong:
A problem occurred evaluating project ':app'.
SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
Total time: 6.504 secs
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:

when i added the following
export ANDROID_HOME=/usr/local/opt/android-sdk
i get the following error message

Answer 1

You must define ANDROID_HOME I copied the relevant parts from the React Native setup guide below and link below that.
On Mac, add this to your ~/.bashrc, ~/.bash_profile or whatever your shell uses:
If you installed the SDK via Homebrew, otherwise ~/Library/Android/sdk
export ANDROID_HOME=/usr/local/opt/android-sdk
On Linux, add this to your ~/.bashrc, ~/.bash_profile or whatever your shell uses:
export ANDROID_HOME=<path_where_you_unpacked_android_sdk>
On Windows, go to Control Panel -> System and Security -> System -> Change settings -> Advanced -> Environment variables -> New

Answer 2

Add a properties file called local.properties in your android project directory (e.g. open your project named as xyz and add this file) and add:
sdk.dir=C\:\\Users\\jeey\\AppData\\Local\\Android\\Sdk
in the file and save it.
Re-run your project.

Answer 3

It seems you have no build tool version 23.0.1 installed in your pc. Lunch your sdk manager and install the specified version.
