first you have to define the color (or you can use one of those that are already defined)

app\App_Resources\Android\src\main\res\values-v21\colors.xml

<resources>
	. . .
	<color name="my_white">#fff</color>
</resources>

function getNavBarHeight() {
  const app = require("application");
  if (app.android) {
    let navBarHeight = 0;
    let windowManager = app.android.context
      .getSystemService(android.content.Context.WINDOW_SERVICE);
    let d = windowManager.getDefaultDisplay();

    let realDisplayMetrics = new android.util.DisplayMetrics();
    d.getRealMetrics(realDisplayMetrics);

git fetch origin pull/ID/head:BRANCHNAME

• ID: ID of the PR,
• BRANCHNAME: name of the local branch which doesn't exist yet.

example:

shiv19

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

after this you can `http-server -S -o` to run it on localhost in https mode.
