cordova-plugin-foreground-service

NOTE: This plugin does not on its own allow the user to execute javascript while the app is in the background. This must be accompanied by another plugin that will create a background process that will give the application background cycles. This plugin mainly exists to solve the problem outlined here. An app will have restricted background processing if it is not considered a "foreground app" for android API 26+ and will prevent background pluggins from functioning properly. With this plugin your application will be a foreground app and let your background services run properly. This plugin may also help with android doze where an application may not run in the background unless it also has a foreground process. Do not expect this plugin on its own to allow your app to execute javascript while in the background.

---

This plugin allows for android devices to continue running services in the background, using a foreground ongoing notification. This is targeted towards use with plugins such as 'cordova-geolocation' that will not run while the app is in the background on android API 26+.

Requirements

Parameters

Icon

The drawable icon can be any drawable image that exists in the resource folder. This means you must copy the icon you want to use into the platforms/android/app/src/main/res/drawable folder set. If no icon can be found using the icon name parameter, a default star icon will be used.

NOTE: The normal android drawable (R.drawable) icons are not available for use as icons. You cannot reference these icons through the start icon parameter. Include your icon manually in the folders mentioned above.

Notification ID

The notification id is a customizable integer that is used to reference the notification that will be launched. This is customizable to avoid conflicting with any other notifications. If this is not included, a default id will be used.

Notification Importance

Notification importance dictates how the notification is initially presented:

Value	Importance	Description
1	IMPORTANCE_LOW	Does not make a sound or heads-up display. (Default)
2	IMPORTANCE_DEFAULT	Makes a sound, but no heads-up display.
3	IMPORTANCE_HIGH	Makes a sound and heads-up display.
