Plugin for the Cordova framework to perform infinite background execution.
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 ope.githubn while in background, but does not deliver the data until the app resumes.
This and other Open-Source Cordova Plugins are developed in my free time. To help ensure this plugin is kept updated, new features are added and bugfixes are implemented quickly, please donate a couple of dollars (or a little more if you can stretch) as this will help me to afford to dedicate time to its maintenance. Please consider donating if you're using this plugin in an app that makes you money, if you're being paid to make the app, if you're asking for new features or priority bug fixes.

This Plugin is a fork of this absolutely awesome Plugin by Katzer! Because it is unmainted, i decided to create this and keep it updated.
Infinite background tasks are not official supported on most mobile operation systems and thus not compliant with public store vendors. A successful submssion isn't garanteed.
Use the plugin by your own risk!
- Android/Amazon FireOS
- Browser
- iOS
- Windows (see #222)
The plugin can be installed via Cordova-CLI and is publicly available on NPM.
Execute from the projects root folder:
$ cordova plugin add cordova-plugin-advanced-background-mode
The plugin creates the object cordova.plugins.backgroundMode and is accessible after the deviceready event has been fired.
It also includes an Ionic Wrapper
document.addEventListener('deviceready', function () {
// cordova.plugins.backgroundMode is now available
}, false);
<!-- Ionic Wrapper -->
import BackgroundMode from 'cordova-plugin-advanced-background-mode';The plugin is not enabled by default. Once it has been enabled the mode becomes active if the app moves to background.
cordova.plugins.backgroundMode.enable();
// or
cordova.plugins.backgroundMode.setEnabled(true);To disable the background mode:
cordova.plugins.backgroundMode.disable();
// or
cordova.plugins.backgroundMode.setEnabled(false);Once the plugin has been enabled and the app has entered the background, the background mode becomes active.
cordova.plugins.backgroundMode.isActive(); // => booleanA non-active mode means that the app is in foreground.
The plugin fires an event each time its status has been changed. These events are enable, disable, activate, deactivate and failure.
cordova.plugins.backgroundMode.on('EVENT', function);To remove an event listeners:
cordova.plugins.backgroundMode.un('EVENT', function);Android allows to programmatically move from foreground to background or vice versa.
cordova.plugins.backgroundMode.moveToBackground();
// or
cordova.plugins.backgroundMode.moveToForeground();Override the back button on Android to go to background instead of closing the app.
cordova.plugins.backgroundMode.overrideBackButton();Exclude the app from the recent task list (works on Android 5.0+).
cordova.plugins.backgroundMode.excludeFromTaskList();Include the app to the recent task list (works on Android 5.0+).
cordova.plugins.backgroundMode.includeToTaskList();The method works async instead of isActive() or isEnabled().
cordova.plugins.backgroundMode.isScreenOff((bool) => {
...
});A wake-up turns on the screen while unlocking moves the app to foreground even the device is locked.
// Turn screen on
cordova.plugins.backgroundMode.wakeUp();
// Turn screen on and show app even locked
cordova.plugins.backgroundMode.unlock();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, text and icon for that notification can be customized as below. Also, by default the app will come to foreground when tapping on the notification. That can be changed by setting resume to false. On Android 5.0+, the color option will set the background color of the notification circle. Also on Android 5.0+, setting hidden to false will make the notification visible on lockscreen.
cordova.plugins.backgroundMode.setDefaults({
title: String,
text: String,
icon: 'icon' // this will look for icon.png in platforms/android/res/drawable|mipmap
color: String // hex format like 'F14F4D'
resume: Boolean,
hidden: Boolean,
bigText: Boolean
})To modify the currently displayed notification
cordova.plugins.backgroundMode.configure({ ... });Note: All properties are optional - only override the things you need to.
In silent mode the plugin will not display a notification - which is not the default. Be aware that Android recommends adding a notification otherwise the OS may pause the app.
cordova.plugins.backgroundMode.setDefaults({ silent: true });Various APIs like playing media or tracking GPS position in background might not work while in background even the background mode is active. To fix such issues the plugin provides a method to disable most optimizations done by Android/CrossWalk.
cordova.plugins.backgroundMode.on('activate', function() {
cordova.plugins.backgroundMode.disableWebViewOptimizations();
});Note: Calling the method led to increased resource and power consumption.
