This is an event that fires when a Cordova application is retrieved from the background.

document.addEventListener("resume", yourCallbackFunction, false);


Cordova consists of two code bases: native and JavaScript. While the native code pulls the application from the background the resume event is fired.

Typically, you will want to attach an event listener with document.addEventListener once you receive the Cordova 'deviceready' event.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Windows Phone 7

Quick Example

document.addEventListener("resume", onResume, false);

function onResume() {
    // Handle the resume event

    <script type="text/javascript" charset="utf-8" src="cordova-2.1.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Call onDeviceReady when Cordova is loaded.
    // At this point, the document has loaded but cordova-2.1.0.js has not.
    // When Cordova is loaded and talking with the native device,
    // it will call the event `deviceready`.
    function onLoad() {
        document.addEventListener("deviceready", onDeviceReady, false);

    // Cordova is loaded and it is now safe to make calls Cordova methods
    function onDeviceReady() {
        document.addEventListener("resume", onResume, false);

    // Handle the resume event
    function onResume() {

  <body onload="onLoad()">

iOS Quirks

Any calls to console.log during your pause event handler will be run now when the app resumes, see the iOS Quirks section for the pause event for an explanation.

  • active event

    This iOS specific event is available as a variant of the resume event, and is often used to detect when the "Lock" button has been pressed to unlock the device when your app is the foreground app. If your app (and device) is enabled for multi-tasking, this will be paired with a subsequent resume event, but only under iOS 5 (effectively all "locked" apps in iOS 5 that have multi-tasking enabled are put to the background).

    Under iOS 5, if you want your app to still run when the device is locked, you will have to disable multi-tasking (UIApplicationExitsOnSuspend - YES) for your app. This is different when you are on iOS 4 - to have your app run when the device is locked, the multi-tasking setting for your app does not matter.

  • resume event

    Interactive functions like alert() when the resume event fires will need to be wrapped in a setTimeout call with a timeout value of zero, or else the app will hang. e.g.

      document.addEventListener("resume", onResume, false);
      function onResume() {
         setTimeout(function() {
                // TODO: do your thing!
              }, 0);
