Cross-platform background-fetch for Cordova / PhoneGap Tutorial
Follows the Cordova Plugin spec, so that it works with Plugman.
This plugin leverages Cordova/PhoneGap's require/define functionality used for plugins.
The plugin creates the object window.plugins.backgroundFetch
with the methods configure(success, fail, option)
, start(success, fail)
and `stop(success, fail).
1.Download the repo using GIT or just a ZIP from Github.
2.Add the plugin to your project (from the root of your project):
phonegap plugin add https://github.com/christocracy/cordova-plugin-background-fetch.git
A full example could be:
onDeviceReady: function() {
var Fetcher = window.plugins.backgroundFetch;
// Your background-fetch handler.
var fetchCallback = function() {
console.log('BackgroundFetch initiated');
// perform your ajax request to server here
$.get({
url: '/heartbeat.json',
callback: function(response) {
// process your response and whatnot.
Fetcher.finish(); // <-- N.B. You MUST called #finish so that native-side can signal completion of the background-thread to the os.
}
});
}
Fetcher.configure(fetchCallback);
}
Implements performFetchWithCompletionHandler, firing a custom event subscribed-to in cordova plugin.
