There are various events provided by cordova to be used by the application. The application code could add listeners for these events.
Cordova consists of two code bases: native and JavaScript.
While the native code loads, a custom loading image displays. However, JavaScript only loads once the DOM loads.
This means the web app may potentially call a Cordova JavaScript function before the corresponding native code becomes available.
deviceready : The deviceready event fires when Cordova is fully loaded.
pause : The pause event fires when the native platform puts the application into the background
resume : The resume event fires when the native platform pulls the application out from the background.
