-Cordova Background Plug-in -========================== +Cordova Background Plugin [![npm version](https://badge.fury.io/js/cordova-plugin-background-mode.svg)](http://badge.fury.io/js/cordova-plugin-background-mode) [![Build Status](https://travis-ci.org/katzer/cordova-plugin-background-mode.svg?branch=master)](https://travis-ci.org/katzer/cordova-plugin-background-mode) +========================= -[Cordova][cordova] plugin to prevent the app from going to sleep while in background. +Plugin for the [Cordova][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 open while in background, but does not deliver the data until the app resumes. -### Plugin's Purpose -This cordova plug-in can be used for applications, who rely on continuous network communication independent of from direct user interactions and remote push notifications. +#### Store Compliance +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. -### :bangbang: Store Compliance :bangbang: -The plugin focuses on enterprise-only distribution and may not compliant with all public store vendors. - -__Update:__ The plugin ID has changed to cordova-plugin-background-mode and is available under npm.

That might increase the chance to submit the app to the app store. ## Usage -The plugin creates the object `cordova.plugins.backgroundMode` with the following methods: - -1. [backgroundMode.enable][enable] -2. [backgroundMode.disable][disable] -3. [backgroundMode.isEnabled][is_enabled] -4. [backgroundMode.isActive][is_active] -5. [backgroundMode.getDefaults][android_specifics] -6. [backgroundMode.setDefaults][android_specifics] -7. [backgroundMode.configure][configure] -8. [backgroundMode.onactivate][onactivate] -9. [backgroundMode.ondeactivate][ondeactivate] -10. [backgroundMode.onfailure][onfailure] - -### Plugin initialization -The plugin and its methods are not available before the *deviceready* event has been fired. +The plugin creates the object `cordova.plugins.backgroundMode` and is accessible after the *deviceready* event has been fired. ```javascript document.addEventListener('deviceready', function () { @@ -133,134 +55,110 @@ document.addEventListener('deviceready', function () { }, false); ``` -### Prevent the app from going to sleep in background -To prevent the app from being paused while in background, the `backgroundMode.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. +### Enable the background mode +The plugin is not enabled by default. Once it has been enabled the mode becomes active if the app moves to background. ```javascript cordova.plugins.backgroundMode.enable(); +// or +cordova.plugins.backgroundMode.setEnabled(true); ``` -### 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. - +To disable the background mode: ```javascript cordova.plugins.backgroundMode.disable(); +// or +cordova.plugins.backgroundMode.setEnabled(false); ``` -### Receive if the background mode is enabled -The `backgroundMode.isEnabled` interface can be used to get the information if the background mode is enabled or disabled. +__Note:__ By using `wkwebview-engine` on iOS, the plugin is enabled by default and cannot be disabled. -```javascript -cordova.plugins.backgroundMode.isEnabled(); // => boolean -``` - -### Receive if the background mode is active (Android/iOS only) -The `backgroundMode.isActive` interface can be used to get the information if the background mode is active. +### Check if running in background +Once the plugin has been enabled and the app has entered the background, the background mode becomes active. ```javascript cordova.plugins.backgroundMode.isActive(); // => boolean ``` -### Get informed when the background mode has been activated (Android/iOS only) -The `backgroundMode.onactivate` interface can be used to get notified when the background mode has been activated. +A non-active mode means that the app is in foreground. + +### Listen for events +The plugin fires an event each time its status has been changed. These events are `enable`, `disable`, `activate`, `deactivate` and `failure`. ```javascript -cordova.plugins.backgroundMode.onactivate = function() {}; +cordova.plugins.backgroundMode.on('EVENT', function); ``` -### Get informed when the background mode has been deactivated (Android/iOS only) -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. - +To remove an event listeners: ```javascript -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 be activated (Android/iOS) or enabled (Windows 10). - -The listener has to be a function and takes the following arguments: - - errorCode: Error code which describes the error - -```javascript -cordova.plugins.backgroundMode.onfailure = function(errorCode) {}; +cordova.plugins.backgroundMode.un('EVENT', function); ``` -## Examples -The following example demonstrates how to enable the background mode after device is ready.

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 isPublic to true will make the full notification show on a secure lockscreen. - -All of these fields are optional - only override the things you need to. +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. ```javascript cordova.plugins.backgroundMode.setDefaults({ title: String, - ticker: String, text: String, - icon: "icon" // this will look for icon.png in platforms/android/res/drawable - resume: true / false, - color: "#123456", - isPublic: true / false, + 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 }) ``` -#### Modify the currently displayed notification -It's also possible to modify the currently displayed notification while in background. - +To modify the currently displayed notification ```javascript -cordova.plugins.backgroundMode.configure({ - title: String, - ... -}) +cordova.plugins.backgroundMode.configure({ ... }); ``` +__Note:__ All properties are optional - only override the things you need to. + #### Run in background without notification 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. ```javascript -cordova.plugins.backgroundMode.configure({ - silent: true -}) +cordova.plugins.backgroundMode.configure({ silent: true }); ``` +## Quirks + +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. + +```javascript +cordova.plugins.backgroundMode.on('active', function() { + cordova.plugins.backgroundMode.disableWebViewOptimizations(); +}); +``` + +__Note:__ Calling the method led to increased resource and power consumption. + + ## Contributing 1.
