Cordova Background Plug-in
Cordova plugin to prevent the app from going to sleep while in background.
Most mobile operating systems are multitasking capable, but most apps dont need to run while in background and not present for the user. Therefore they pause the app in background mode and resume the app before switching to foreground mode. The system keeps all network connections open while in background, but does not deliver the data until the app resumes.

Plugin initialization
The plugin and its methods are not available before the deviceready event has been fired.
document.addEventListener('deviceready', function () {
// cordova.plugins.backgroundMode is now available
}, false);
Prevent the app from going to sleep in background
To prevent the app from being paused while in background, the backroundMode.enable
interface has to be called.
Further informations
- The background mode will be activated once the app has entered the background and will be deactivated after the app has entered the foreground.
- To activate the background mode the app needs to be in foreground.
cordova.plugins.backgroundMode.enable();
Pause the app while in background
The background mode can be disabled through the backgroundMode.disable
interface.
Further informations
- Once the background mode has been disabled, the app will be paused when in background.
cordova.plugins.backgroundMode.disable();
Get informed when the background mode has been activated
The backgroundMode.onactivate
interface can be used to get notified when the background mode has been activated.
cordova.plugins.backgroundMode.onactivate = function() {};
Get informed when the background mode has been deactivated
The backgroundMode.ondeactivate
interface can be used to get notified when the background mode has been deactivated.
Further informations
- Once the mode has been deactivated the app will be paused soon after the callback has been fired.
cordova.plugins.backgroundMode.ondeactivate = function() {};
Get informed when the background mode could not been activated
The backgroundMode.onfailure
interface can be used to get notified when the background mode could not been activated.
The listener has to be a function and takes the following arguments:
- errorCode: Error code which describes the error
cordova.plugins.backgroundMode.onfailure = function(errorCode) {};
Examples
The following example demonstrates how to enable the background mode after device is ready. The mode itself will be activated when the app has entered the background.
document.addEventListener('deviceready', function () {
// Android customization
cordova.plugins.backgroundMode.configure({ text:'Doing heavy tasks.'});
// Enable background mode
cordova.plugins.backgroundMode.enable();
// Called when background mode has been activated
cordova.plugins.backgroundMode.onactivate = function () {
setInterval(function () {
console.log('App is running in background');
});
}
}, false);
Platform specifics
Android Customization
To indicate, that the app is executing tasks in background and being paused would disrupt the user, the plug-in has to create a notification while in background like a download progress bar.
The title, ticker and text for that notification can be customized in the following way at any time:
cordova.plugins.backgroundMode.configure({
title: String,
ticker: String,
text: String
})
By default the app will come to foreground when taping on the notification. That can be changed also.
cordova.plugins.backgroundMode.configure({
resume: false
})
