   The path of `/usr/lib/android-sdk`
   
   should be a directory of several directories, more importantly it should have build-tools, platforms, tools, and platform-tools. See below 
   
   ```
   $ ls
   build-tools  extras    ndk-bundle  platforms       sources        tools
   emulator     licenses  patcher     platform-tools  system-images
   ```
   If `/usr/lib/android-sdk` doesn't look anything like above, then you may have the wrong directory!
   
   Note that some of the command line tools are in these sub-directories. To address that, I have the following inside my .bashrc. While `ANDROID_HOME` should be the only thing that is required for cordova, the other paths may be helpful to debug the android sdk installation.
   
   ```bash
   # ANDROID_HOME should be a directory that looks above
   export ANDROID_HOME="/usr/lib/android-sdk"
   
   # ANDROID_HOME is deprecated and being replaced by ANDROID_SDK_ROOT, but many tools
   # still relies on ANDROID_HOME
   export ANDROID_SDK_ROOT=$ANDROID_HOME
   
   export PATH="$PATH:$ANDROID_HOME/tools" # Required for the android binary
   # export PATH="$PATH:$ANDROID_HOME/tools/bin" # Some android installations have their binaries located in tools/bin instead of tools/
   
   export PATH="$PATH:$ANDROID_HOME/platform-tools" # Required for using adb (Android debug bridge) from command line
   
   # This should be set to the installed build-tools installation, which may be different. 
   # Look inside the build-tools folder to see which build tools versions you have installed, and 
   # use one of them.
   # Required for accessing build and deployment tools such as zipalign
   export PATH="$PATH:$ANDROID_HOME/build-tools/28.0.3"
   ```
   
   Of course after modifying the .bashrc you'll need to restart the terminal for the changes to take effect.
   
   After you restart your terminal if you run `avdmanager --help` then you should see:
   
   ```
   Usage:
         avdmanager [global options] [action] [action options]
         Global options:
     -s --silent     : Silent mode, shows errors only.
     -v --verbose    : Verbose mode, shows errors, warnings and all messages.
        --clear-cache: Clear the SDK Manager repository manifest cache.
     -h --help       : Help on a specific command.
   
   Valid actions are composed of a verb and an optional direct object:
   -   list              : Lists existing targets or virtual devices.
   -   list avd          : Lists existing Android Virtual Devices.
   -   list target       : Lists existing targets.
   -   list device       : Lists existing devices.
   - create avd          : Creates a new Android Virtual Device.
   -   move avd          : Moves or renames an Android Virtual Device.
   - delete avd          : Deletes an Android Virtual Device.
   ```
   
   Then it looks like your environment is configured properly and you can try running cordova again. Hope this helps.
