如何创建运行应用程序甚至用户关闭它的android(how can i create run app even user close it android)

想要创建应用程序cordova和离子为Android到alaram在某些时候像2:50我希望程序运行甚至关闭程序我使用katzer / cordova-plugin-background-mode插件，但当我关闭程序，它是关闭，不要仍然在后台运行这是代码

// 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 () { var dd = new date(); var h = dd.getHours(); var m = dd.getMinutes(); if(h == 2 && m ==50){ alert("2:50"); } }, 3000); } }, false);

如何让应用程序仍然运行甚至用户关闭程序，如闹钟或一些程序提醒？
