在后台获取Ionic/Cordova app中的位置

Question

如果我关闭我的Ionic/Cordova应用程序(iOS和Android),是否可以运行后台服务？

为此,我选择了插入https://github.com/katzer/cordova-plugin-background-mode

到目前为止我有这个代码:

$ionicPlatform.ready(function () {
            cordova.plugins.backgroundMode.isEnabled();

            cordova.plugins.backgroundMode.configure({
                silent: true
            }) 
              ............
            ///do some task
)}

如果应用程序转到前台,它可以正常工作,但是一旦我关闭应用程序,我运行的任务也会停止.那么即使应用程序关闭,有没有任何解决方法/方法可以让我的任务运行？

编辑:

我还为iOS和Andorid添加了权限,但我得到了相同的结果.

编辑2:

我在后台尝试做的是编写自己的重要位置更改服务实现,因为没有适用于iOS和Android的Cordova或PhoneGap的免费插件.

我最近在我的项目中实现了这样的功能.我确实使用了Ionic,我确实使用了Katzer的Cordova插件背景模式.(现在我正在通过iOS 9.2模拟器运行后台进程).

这是一个让它工作的代码片段:

// Run when the device is ready
document.addEventListener('deviceready', function () {

    // 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.
    cordova.plugins.backgroundMode.setDefaults({ 
        title:  'TheTitleOfYourProcess',
        text:   'Executing background tasks.'
    });

    // Enable background mode
    cordova.plugins.backgroundMode.enable();

    // Called when background mode has been activated
    cordova.plugins.backgroundMode.onactivate = function () {

        // Set an interval of 3 seconds (3000 milliseconds)
        setInterval(function () {

            // The code that you want to run repeatedly

        }, 3000);
    }
}, false);

这是一个Ionic 2示例ES6准备就绪:

// Import the Ionic Native plugin 
import { BackgroundMode } from 'ionic-native';

// Run when the device is ready
document.addEventListener('deviceready', () => {

    // 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.
    BackgroundMode.setDefaults({ 
        title:  'TheTitleOfYourProcess',
        text:   'Executing background tasks.'
    });

    // Enable background mode
    BackgroundMode.enable();

    // Called when background mode has been activated
    // note: onactive now returns an returns an observable that emits when background mode is activated
    BackgroundMode.onactivate.subscribe(() => {
          // The code that you want to run repeatedly
    });
}, false);
