automatically downloading pre-requisites

[jimmckeeth]

Needs Java SDK & Android Studio. See if it is possible to automatically download and install them. Provide option for user.

• Adopt Open JDK v8 with Hotspot JVM
• Android SDK Command line tools from the bottom of the list and not the full Android Studio.
• Use the sdkmanager command-line tool to install as follows

  sdkmanager "cmdline-tools;latest" "platform-tools" "platforms;android-30"
  
  

Could also use SDK Manager to install updates, etc.
