问题
I inadvertently accepted android studio's upgrade suggestion to 2.3 (canary), although I had always had it set to check for the developer channel, not canary, somehow that got switched. Now I no longer have a 'Launch Standalone SDK Manager' option in my 'SDK Manager' window.
I liked the standalone manager for various reasons, including that it suggested what needed to be downloaded and upgraded. The regular sdk manager lists a lot of things I expect I don't need like 'CMake', 'LLDB', 'Constraint Layout for Android', 'Solver for ConstraintLayout', 'Google Play APK Expansion Library' ('Google Play APK Expansion Library rev 3' is already installed, so do I need this too?), etc.
Is the standalone sdk manager unavailable for 2.3 canary 2, or is there something more I need to do to get it?
回答1:
I also have updated to the Canary version 2.3 and I'm amazed that they took it away there.. but you can still start it via the SDK Manager.exe located in your sdk folder
C:\Users\You\AppData\Local\Android\sdk

Present:Today when i was trying to launch, the terminal says,
The android command is no longer available.
For manual SDK and AVD management, please use Android Studio.
Past:
I also face the problem after updating to Canary version 2.3 on my mac.. On Mac or Linux, open a terminal and navigate to the tools/ directory in the location where the Android SDK is installed, then execute android sdk
or for only mac user go to folder located in /Users/your mac account name/Library/Android/sdk/tools
and double click android to Launch Standalone SDK Manager
My Advice: Stop Searching for Launch Standalone SDK Manager and get use to be of android studio SDK manager and just choose the Show Package Details for more detailed description like Launch Standalone SDK Manager.

With the 2.3 Canary update, when using SDK Manager.exe or tools/android.bat, no manager is opened. However tools/android.bat give a pretty good answer to why it is not working:
The "android" command is no longer available.
For manual SDK and AVD management, please use Android Studio.
For command-line tools, use
tools\bin\sdkmanager.bat and tools\bin\avdmanager.bat
We can still use command-line tools, but no more standalone SDK manager.

Yes, "Launch Standalone SDK Manager" option in Android Studio V2.3 is not available, But you can still start it via SDK Manager.exe located in your sdk folder.
c:\Users\You_User_Account_Name\AppData\Local\Android\SDK Manager.exe
Enjoy Android Studio with new features.

I just received an official response from AOSP - Project Member #1 uchid...@google.com deprecated feature , please check latest stable version Android 2.3
The link is now gone, and it is intentional.

Yes the standalone sdk manager option is missing in Android Studio 2.3. Get yourself used to the sdk manager available in Android Studio settings.
Also if you are installing Android Studio from scratch, you will not be available to find Sdk Manager.exe from C:\Users\You\AppData\Local\Android\sdk or anywhere you install it.
