Changes to the Android SDK Tooling
Changes to how the Android SDK manages the installed API levels and AVDs.
Changes to Android SDK Tooling
In modern versions of the SDK Tools for Android, Google has removed the existing AVD and SDK managers in favour of new command line interface (CLI) tooling. The former android program has been removed and the the GUI(Graphical User Interface) managers in Visual Studio for Mac and older versions of Xamarin for Visual Studio will no longer work past version Android SDK Tools.
Attempting to use the android program via the command line will result in an error message like the following:
The "android" command is deprecated. For manual SDK, AVD, and project management, please use Android Studio. For command-line tools, use tools\bin\sdkmanager.bat and tools\bin\avdmanager.bat
Thus you will need to use the CLI tools to manage and update your emulators and Android SDK.
The following programs now make up the command line interface for the Android SDK tools:
Added In: Android SDK Tools 25.2.3 (November, 2016) and higher.
There is a new program called sdkmanager in the tools/bin folder of your Android SDK. This tool is used to maintain the Android SDK at the command line. For more information about using this tool, see sdkmanager.
Added In: Android SDK Tools 25.3.0 (March, 2017) and higher.
There is a new program called avdmanager in the tools/bin folder of your Android SDK. This tool is used to maintain the AVD's for the Google Android Emulator. For more information about using this tool, see avdmanager.
You can downgrade your Android SDK Tools version by installing a previous version of the Android SDK from the Android Developer website.
Using the old GUI
You can still use the original GUI by running the android program inside your tools folder as long as you are on Android SDK Tools version 25.2.5 or lower.
