Question

I have error when i start running android

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. 

Answer 1

• Go to the android/ directory of your react-native project
• Create a file called local.properties with this line:

sdk.dir = /Users/USERNAME/Library/Android/sdk 

Where USERNAME is your macOS username

Answer 2

1. Go to your React-native Project -> Android
2. Create a file local.properties
3. Open the file

4. paste your Android SDK path like below

   • in Windows sdk.dir = C:\\Users\\USERNAME\\AppData\\Local\\Android\\sdk
   • in macOS sdk.dir = /Users/USERNAME/Library/Android/sdk
   • in linux sdk.dir = /home/USERNAME/Android/Sdk

Replace USERNAME with your user name

Now, Run the react-native run-android in your terminal.
