Android SDK Tools option is missing from SDK Manager in Android Studio 3.6.1

Question

On a freshly installed macOS Catalina, I installed Android Studio 3.6.1.

I've got the following error when I ran flutter doctor in the course of setting up flutter SDK on my Mac.

[!] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
    ✗ Android license status unknown.
        Try re-installing or updating your Android SDK Manager.
        See https://developer.android.com/studio/#downloads or visit
        https://flutter.dev/setup/#android-setup for detailed instructions.

I re-installed Android Studio and follow the instructions in the second link in the error message, but these links do not seem to help resolving the issue. I also tried the following:

$ flutter doctor  --android-licenses

Which gives the following error:

Android sdkmanager tool not found
(/Users/username/Library/Android/sdk/tools/bin/sdkmanager).
Try re-installing or updating your Android SDK,
visit https://flutter.dev/setup/#android-setup for detailed instructions.

I checked my installation and found out that tools directory is missing under ~/Library/Android/sdk/.

Also, I found out Android SDK Tools option is missing from SDK Tools tab in SDK Manager of the Android Studio as shown in this screenshot. (Android SDK Tools option was present on my previous installation of Android Studio 3.5.3.)

Has anyone had the similar problem? I am not sure what I'm doing wrong. If anyone can show me how I can fix this issue, I'd appreciate it! (This is my first question on Stack Overflow. Please excuse me for lengthy post.)

Seriously, they want every time their developers spend hours in doing R&D just to get little things done after their new release. – Jadda

Answer 1

I'm using Linux but I guess the problem might be the same.

Launch Android Studio and go to "SDK Manager" - you can launch it after creating a blank project and going "Tools -> SDK Manager" under the "AVD Manager" option. In the new window open "System Settings -> Android SDK". From there pick "SDK Tools". Now you need to uncheck the "Hide Obsolete Packages" option in the bottom of the window. Now there should appear a new option: "Android SDK Tools (Obsolete)" - check that, hit "Apply" - it will download the files and "Tools" folder will appear in the Android folder. Then simply run "flutter doctor" in the terminal and you should be asked to accept some licenses - simply run:

$ flutter doctor --android-licenses

It helped me. I don't know why this option went obsolete when Flutter requires it anyway. Check the settings printscreen.

Unchecking Hide Obsolete Packages solved the issue. Thank you for pointing it out! – Itin

Step1. Download latest sdk tools from https://androidsdkmanager.azurewebsites.net/SDKTools.(changed https://androidsdkmanager.azurewebsites.net/sdk_tools.html) up to 2020-03-08 the latest version is 26.2.0.

Step2. Unzip and then copy "tools" folder into android-sdk folder. "tools" and "build-tools" is in the same depth.

Step3. flutter doctor --android-licenses

Step4. flutter doctor

I wonder why this URL is not documented anywhere on the Android Studio download page; it would have saved me so much time! Thank you for that! – Solace

Above link is not working anymore. – Fiord

Answer 3

1. Open the Android Studio SDK Manager
2. In the Android SDK tab, uncheck Hide Obsolete Packages
3. Check Android SDK Tools (Obsolete) Check and download it!

Answer 4

I had a similar problem with Android Studio 3.6.1 (not involving flutter): the platform-tools directory got installed within another platform-tools directory, so Android Studio couldn't find adb, and so couldn't communicate with my phone. A completely fresh re-install of Android Studio didn't even help. I ended up manually moving the platform-tools one directory up and that fixed it:

% cd ~/Library/Android/sdk
% mv platform-tools platform-tools-bad
% mv platform-tools-bad/platform-tools .
