I just started learning react-native a couple days ago, and I got a bug during installation and setting up. The moment I run the cmd "npx react-native run-android", and I got this error.

Jetifier found 896 file(s) to forward-jetify. Using 8 workers... info JS server already running. info Installing the app...

FAILURE: Build failed with an exception.

  • What went wrong: Could not determine the dependencies of task ':app:installDebug'.

java.io.IOException: The filename, directory name, or volume label syntax is incorrect

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

  • Get more help at https://help.gradle.org

BUILD FAILED in 3s

error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup. Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081

FAILURE: Build failed with an exception.''

Please help me guys. Thank you very much.

Might be the issue with the incorrect SDK location. Can you verify if there is a local.properties in your android folder under your React Native project with right sdk location path in it

Also verify the below code in gradle-wrapper.properties present in gradle/wrapper folder

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.3- 
all.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
