Solution:

Step 1 :  

Either local.properties file is missing in your android folder of react native app or the sdk path is incorrect in the file 

(i) Make sure you have local.properties file in your android folder if not add local.properties file 

Create local.properties file under android folder in react native app if you don't find it there

(ii) Open Android Studio get the Android SDK Location from 

Android Studio -> Preferences -> Appearance & Behaviour -> System Settings -> Android SDK 

Here you can copy the path provided in the box next to Android SDK Location and add to your local.properties file as such 

sdk.dir = SDK PATH COPIED

(iii) Next from Visual Studio Terminal enter the command 

cd android 

and then 

./gradlew clean

(iv)  Enter the command below to enter the react native project created 

cd PATH_OF_YOUR_REACT_NATIVE_APP

and then run the app with the below command 

npx react-native run-android 

Step 2:

Open gradle-wrapper.properties from Android Project and change your distribution url as below and sync

distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip
