A status bar notification is a nice way to alert the user about some update from your application, when running in background, specially when you require a response from the user for the same. It adds an icon to the system's status bar along with an optional ticker-text message and an expanded message in the Notifications window. When the user selects the expanded notification message, Android fires an Intent that is defined by the notification which is usually used to launch an Activity. In this article, I will show you how we can implement this notification system in our application.
Sometimes we may require the user to set time in our application. While doing so instead of asking the user to enter the time data in raw form, we can provide him with a beautiful GUI to input the data.

Whenever the user has to input a date, its always a good idea to assist him/her with a widget which allows the user to select a particular day, month and year.

As soon as user starts typing in a word or phrase, the application shows a list containing the probable words or phrases that the user wants to type in without the user actually typing it in completely. This feature makes application more user friendly and improves user experience. We will create a textbox widget which supports auto complete feature.
