How can I allow orientation rotation while using manifest.json?

Question

When I use a manifest.json file within my web application and "add to home screen" on Chrome for Android, it loads in fullscreen mode (great) but also gets locked in portrait orientation (not great).

I want to load in fullscreen, but still allow for orientation rotation. Is this possible?

{
  "name": "MyApp",
  "icons": [
    {
      "src": "launcher-icon-0-75x.png",
      "sizes": "36x36",
      "type": "image/png",
      "density": 0.75
    }
  ],
  "start_url": "/home",
  "display": "standalone",
  "orientation": "natural" // I have tried natural, any, leaving this property out altogether without success
}

According to boyofgreen, you should be able to supply one of many orientation options .

Answer 1

It turns out Chrome for Android was aggressively caching my manifest.json file. By manually clearing the cache "from the beginning of time" and setting the orientation property to a value of any I was able to get the desired behavior.

Worth noting, an orientation value of natural did not allow the screen to rotate.

Answer 2

I had the same problem with my app (linkthethings.com). I had used the android add to home screen. As well as removing the manifest.json orientation value I also had to uninstall the app and install it again. Even using clear cache option described in Clear Workbox cache of all content had no results.
