React Native make android app load in genymotion

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.

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.
