At the time of writing, there are 3 different `sdkmanager` binaries after updating. ```bash $ANDROID_SDK_ROOT/tools/bin/sdkmanager --version #=> 26.1.1 $ANDROID_SDK_ROOT/cmdline-tools/tools/bin/sdkmanager --version #=> 3.6.0 $ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager --version #=> 4.0.0 ```
