var queryParams = window.location.search.substr(1).split('&').reduce(function (qs, query) {
  var chunks = query.split('=');
  var key = chunks[0];
  var value = decodeURIComponent(chunks[1] || '');
  var valueLower = value.trim().toLowerCase();
  if (valueLower === 'true' || value === 'false') {
    value = Boolean(value);
  } else if (!isNaN(Number(value))) {

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Here the SDK is under /usr/local/share/android-sdk because I may switch to a different Catalina user in the future, but it works fine under /Users/<your_user>/Library/Android/sdk as well.

Prerequisites:

See for brew, python3 and NodeJS on nvm see gist https://gist.github.com/agrcrobles/3d945b165871c355b6f169c317958e3e
