Tips for determining if a mobile web browser is active on a mobile device's foreground or background

I'm currently developing an angularjs html5 application.

Just a quick question - is it possible to utilize pause/resume events in a mobile web application? Alternatively, you can help me by answering my question about how to check if the browser window has focus in a mobile web browser.

I came across a useful reference on how to check if the app is running in the foreground or background in Ionic/Cordova/PhoneGap.

I am unsure whether Cordova/ng-cordova can be used in a mobile web browser. Any guidance on this would be greatly appreciated. My goal is to track events such as: - incoming phone calls
- pressing the home button.

I want to be able to track all these events in a mobile web browser environment.

Implementing the cordova background mode plugin

cordova plugin add cordova-plugin-background-mode

Activating the background mode once the plugin is enabled and the app goes into the background.

cordova.plugins.backgroundMode.isActive(); // => boolean

For more details, visit: https://github.com/katzer/cordova-plugin-background-mode

Follow these steps:

  1. Start by installing cordova-plugin-device, as it's a dependency for cordova-plugin-background-mode. Then proceed with installing cordoba-plugin-background mode

    cordova plugin add https://github.com/katzer/cordova-plugin-background-mode.git

  2. After both are installed, include this code in your controller

     .controller('HomeCtrl', function($scope){

        if(cordova.plugins.backgroundMode.isActive()){
           console.log("Background state");
        }else{
           alert('HELLO');
        }
 });

  3. Step 2 is your opportunity to test if the plugin is functioning correctly. Put your desired background tasks inside the 'if' block.

  4. Attach this controller to an HTML page that gets called regularly, like I've done on Home.html.

Reach out if you encounter any issues.
