I wanted to start learning Flutter, so I'm following the guide, but I'm already stuck on the very first step. I haven't done anything other than create a brand new app, but when I hit "Run" in Android Studio I get the following error:
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Failed to install the following Android SDK packages as some licences have not been accepted.

To build this project, accept the SDK license agreements and install the missing components using the Android Studio SDK Manager.

Looking at people with similar problems, the most common solution seemed to be running yes | ~/Android/tools/bin/sdkmanager --licenses, but I don't have a folder or file called sdkmanager. My entire document tree is different actually, although I just went through the official Android Studio download process for Ubuntu. For my document structure, I have
~/Android/Sdk/$ ls
build-tools patcher platform-tools sources
emulator platforms skins
none of which contain tools, bin, or sdkmanager.
I also opened SDK Manager in Android Studio, and went to the SDK Tools tab and updated Build-Tools and accepted the license, then quit and reopened Android Studio, but I'm getting the same error. I can't find anyone with the same file structure as me. Anyone know what I can do?
I'm starting to think the real issue is the contents of my Android folder. When I run flutter doctor I get this message
[✓] Flutter (Channel stable, v1.12.13+hotfix.8, on Linux, locale en_US.UTF-8)

Try re-installing or updating your Android SDK Manager.

But when I run flutter doctor --android-licences I get the following error message:
Android sdkmanager tool not found (/home/greg/Android/Sdk/tools/bin/sdkmanager).

I don't in fact have a tools folder, or bin, or sdkmanager. I did try uninstalling and reinstalling Android Studio, but nothing changed. Did I download an incorrect package or something? I downloaded it directly from https://developer.android.com/studio/#downloads, so how is it possible that the contents seem to be incorrect? I have 100GB free, so space constraints didn't stop it from being installed. I don't have any internet issues either.
I'm facing the same issue too on MacOS.
I just downloaded the Android Studio today (android-studio-ide-192.6241897-mac) and the /tools folder is missing for me too.
The only way I can see an 'sdkmanager' inside the 'Android/' directory is when I install cmdline-tools and find it in the bin folder. but that doesn't solve the problem.
EDIT
Found the solution. Apparently, the 'tools/' folder doesn't exist in the latest Android Studion build.
You can still install the SDK tools using the SDK manager in the Android studio.
Open the SDK manager and go to the 'SDK Tools' tab. On the bottom uncheck the 'Hide Obsolete packages' checkbox.
After doing that an option to install the 'Android SDK Tools (obsolete)' package will appear.
Install them and run the flutter doctor again.
And it works after accepting the licenses
