Now let’s see how to implement progressive web app in your website and install it in android.

NOTE* This code only allows installing of your website in Android devices, so It won’t work for IOS or desktop applications.


STEP 1 : 

  • Create a file with name manifest.json and copy and paste the below code.
  • Change the required details according to you.
    • Name : Your website name
    • Short Name : Name to show with icon.
    • Description : Your website description.
    • Scope & Start URL* : Your website’s main URL. (Important)
    • Background color 
    • Theme Color : Your websites theme color.
    • Icon->src : Icon to show after installing app.
    "name": "Vbloggers",
    "short_name": "Vbloggers",
    "description": "Vbloggers For you, For Me, For All.",
    "scope": "",
    "start_url": "",
    "display": "standalone",
    "orientation": "portrait",
    "theme_color": "#c80000",
	"icons": [
	      "src": "",
	      "sizes": "512x512",
	      "type": "image/png",
          "purpose": "any maskable"

STEP 2 : 

  • Create a another file with name sw.js and copy and paste the below code.
  • Change index.php to your home index page.
  • Sometimes changing the file name to other may not be visible in your website due to cache, Like changing index.php to index.html and saving file, but when you open that URL the file name may not change to index.html rather shows index.php event it exists in your core file.
  • This is due to cache, In that case change the file name and try again, It works. 
self.addEventListener('install', function(event) {
    event.waitUntil('sw-cache').then(function(cache) {
        return cache.add('index.php');
self.addEventListener('fetch', function(event) {
    caches.match(event.request).then(function(response) {
        return response || fetch(event.request);

STEP 3 : 

  • Upload both manifest.json and sw.js to your root folder
  • Now link the manifest.json file  and copy the below script.
  • Inside navigator.serviceWorker.register include your sw.js file name, If you have another file name then change to it.
<meta name="theme-color" content="#c80000">
<link rel="manifest" href="manifest.json">
	if('serviceWorker' in navigator){
  •  That’s it now save your header and run the website in your android device. and click on the bottom link which says add Vbloggers to home page.
  • Click on that link then a pop up opens and says install, Click on install, and your web app is installed 
  • To check it go to your apps list and search for your app and open it, You can see a feel and look of android application.
