How to check installed Android SDK versions?

Description

I want to check what Android SDK versions are available on target machines using command-line.

Dev env

• macOS 11.6 (Big Sur) x64
• Android Studio Bumblebee Patch 1
• Android SDK version 31
• Android Gradle Plugin: 4.1.3
• Gradle: 6.5
• Gradle JDK: 1.8
• Kotlin: 1.6.10

Build env

• Ubuntu 18.04.4 LTS
• Android SDK version 31
• Gradle: 6.6
• JDK: 11

Tried approaches

• 2 Ways to Check Android SDK Versions (2022)
  • avdmanager list target
    => It works on mac, only if you use the right avdmanager. In my case, use sh ${ANDROID_SDK_ROOT}/cmdline-tools/latest/bin/avdmanager list target. But this not work in my build env. Maybe cmdline-tools are not installed.
  • android list target
    => Not work for me. This command should be sh ${ANDROID_SDK_ROOT}/tools/android list target, if ${ANDROID_SDK_ROOT}/tools/ not in PATH env var. And the command shows the following error message: 'The "android" command is deprecated.'
• How to determine the version of android SDK installed in computer?
  • /tools/bin/sdkmanager --version
    => Not work for me. "/tools/bin/sdkmanager" will cause NoClassDefFoundError. The correct path for me is "${ANDROID_SDK_ROOT}/cmdline-tools/latest/bin/sdkmanager". But "--version" shows the sdkmanager version, not sdk version. If you want to get installed sdk version, you can use sh ${ANDROID_SDK_ROOT}/cmdline-tools/latest/bin/sdkmanager --list_installed. It shows but only sdk, but all tools and images installed. To show sdk only, you can use sh ${ANDROID_SDK_ROOT}/cmdline-tools/latest/bin/sdkmanager --list_installed | sed -n 's/.*platforms;//p'. But this not work in my build env. Maybe cmdline-tools are not installed.
• Failed to run sdkmanager --list with Java 9
  • /tools/bin/sdkmanager --list with sdkmanager script modified. Where update the file DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'.
    => Not work for me.
• Print the sdk platforms' folders
  • ls ${ANDROID_SDK_ROOT}/platforms
    => It works!

Solutions

• Print the sdk platforms' folders
