getting this error: java.net.BindException: Address already in use: Cannot bind

Question

Hello am building a flutter apk using vscode but I get the error below, any help on how to go about it. Did a research but am getting no solution. I have configured JAVA_HOME well in gradle setting in android studio yet gradle am still getting the same error

FAILURE: Build failed with an exception.

* What went wrong:
Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the User Manual chapter on the daemon at https://docs.gradle.org/6.5/userguide/gradle_daemon.html
Process command line: C:\Program Files\Android\Android Studio\jre\bin\java.exe --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.invoke=ALL-UNNAMED --add-opens java.prefs/java.util.prefs=ALL-UNNAMED -Xmx1536M -Dfile.encoding=windows-1252 -Duser.country=US -Duser.language=en -Duser.variant -cp C:\Users\cs\.gradle\wrapper\dists\gradle-6.5-all\2oz4ud9k3tuxjg84bbf55q0tn\gradle-6.5\lib\gradle-launcher-6.5.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 6.5

Answer 1

That's because you start debugging while hotspot is active in your device All you need to do is :

1. Open your Task Manager alt+ctrl+delete
2. End-Task of all open-JDKs
3. turn of mobile-hotspot
4. start debug again
5. Keep Coding

Answer 2

What worked for me on Windows;

• I opened task manager (with Ctrl+Alt+Delete).
• Stopped and/or ended processes for all running openJDKs (like any java.exe).
• Just re-run Gradle and done! Worked fine for me.
