Specifically, this part:
Go to sdk manager, and download Android SDK command line tools and try again

I'm having a (seemingly common) unknown license status issue. However, common fixes have not worked, such as flutter doctor --android-licenses, which can be seen in the console output below. I have gone to the link also - not helpful.

Any and all help will be greatly appreciated. Many thanks in advance :)
Installing the Android SDK Command-line Tools should fix the issue. Navigatie to settings,Appearance & Behavior -> System Settings -> Android SDK
Then run:
flutter doctor --android-licenses
Which should give you something like this:
coolcoders#myhost ~ % flutter doctor --android-licenses
5 of 7 SDK package licenses not accepted. 100% Computing updates...
Review licenses that have not been accepted (y/N)? y
I have
Install Andriod Studio and Java. This is the current issue.
I can't do anything. A similar error was posted and confused me futher

After a lot of searching and a lot of diff types of error ranging from environmental variable errors and java errors, i just uninstalled android studio, java and flutter files
deleted appdatas etc. and reinstalled it again now flutter doctors works fine.
i know this is not a good solution but someone could try this if all else fails.
thks
The crux of this issue seem to be with spaces in the Android SDK path, e.g. if your user name on windows is "John Smith", it will fail to detect the android SDK. The solution is to move 'C:\Users\John Smith\AppData\Local\Android\Sdk' to a path with no spaces, e.g. 'C:\Android\Sdk'. Then run the following
flutter config --android-sdk "C:\Android\Sdk"
PS: for a related issue where it says "[!] Android Studio (not installed)", run the following to manually point it to the default Android Studio install location
flutter config --android-studio-dir "C:\Program Files\Android\Android Studio"
I have seen similar issues but they somehow could not resolve my issue.
I am currently using Windows and Versions Java 8, Java SDK 13.0.1, Android Studio v3.5.2.
1) I First typed flutter doctor and got the following error : Android license status unknown.
2) I then entered flutter doctor --android-licenses and got the following command
A newer version of the Android SDK is required. To update, run:
C:\Users\user\AppData\Local\Android\sdk\tools\bin\sdkmanager --update
3) Running this line I ended up here :
D:\flutter\flutter>C:\Users\user\AppData\Local\Android\sdk\tools\bin\sdkmanager --update

Please let me know the simple steps i could follow as I am confused about this a lot!
To resolve, try running flutter doctor --android-licenses. This should prompt you to accept licenses just type y and enter to accept the licence if error persists check out this issue
