Answer 2

Kindly first of all check your latest sdk first step:

Second step:

Third step: Run flutter doctor --android-licenses Press Y against each agreement

If you have done above steps then please follow the bellow process

Flutter provides a command to update the Android SDK path:

Use flutter config --android-sdk <path-to-your-android-sdk-path>

Normally the Android SDK path is C:\Users[your Local user folder]\AppData\Local\Android\Sdk

For Me. The problem is the antivirus program. It denied access to starting the flutter daemon on port 5037. I disabled/exited the antivirus program. Then it works.

This generally occurs if the platform-tools are not installed properly. Reinstalling the platform tools might fix this problem. Open Android Studio, click SDK Manager in the toolbar or click Tools > SDK Manager, click SDK Tools, then uncheck Android-SDK Platform-Tools (as shown above). After this, open C:\Users\Username\AppData\Local\Android\Sdk and delete the platform-tools folder. Then go back to Android Studio and in the SDK Tools, check-mark ‘✓’ Android-SDK Platform-Tools.

Answer 6

You have to just do this on windows

the adb daemon was unable to start (when trying adb devices). Doing the following via an Admin CMD worked: net stop winnat, then

net start winnat.

Then try again.

Happend to me on osx, somehow just starting Android studio and checking the 'device manager' solved the problem.
