You can use the local notification plugin to achieve this. Its works perfectly even if you app is minimized.
Here is the link https://github.com/zhuochun/local-notification
You can follow the steps to add the plugin as stated in readme
<script type="text/javascript">
var notification = cordova.require("cordova/plugin/localNotification")
document.addEventListener("deviceready", appReady, false);
function appReady() {
console.log("Device ready");
notification.add({
id: 1,
date: new Date(),
message: "Phonegap - Local Notification",
subtitle: "Subtitle is here",
ticker: "This is a sample ticker text",
repeatDaily: false
});
}
</script>
Try this plugin.
