This form of displaying information can be efficient and used for a quick display on the home screen. The implementation for creating an App Widget is also extensive and can be found through the android developer guide at http://developer.android.com/guide/topics/appwidgets/index.html.

Since app widgets are a great way to embed information on the home screen and Due to these reasons, we are looking into displaying the information in our application using widgets for the android platform.

In order to create an application widget for android, the following are needed:

AppWidgetProviderInfo.xml
AppWidgetProvider class implementation
View layout xml

Standard Widget Anatomy

The typical Android app widgets are made up of three components:

bounding box
frame
widget's graphical controls and other elements

Determining the size a widget

Each widget takes up a defined width and height. On phones the typical grid is a 4x4 and on tablets the grid is an 8x7. The following table helps with relative sizes for the # of cells relative to dp.

App Widget Templates Pack

It is also a good idea to look at the widget design templates for styles when updating or creating a new widget. The package includes 9 background graphics, XML, and source Adobe Photoshop files.

Comparison Factor

An app with a similar implementation of widgets for data monitoring to our current plans is called Onavo. In their application they provide 3 widgets for the home screen as shown below:

App Watch - to track data used by each app in a selected time frame
Data Plan Used - notifies you of how much of your data plan is left this month using a progress bar
Live Data Usage - monitors which apps have been using data in the last 30 min.

Onavo also offers a service for iOS devices that allows data to be compressed through Onavo's servers, however there are no widget options for iOS devices.

Our application on the other hand will focus on the biggest factor for users which is the 2nd widget above. The major use for our app widget will be to show the data usage in one pay cycle in an innovative and fun way that looks appealing on the home screen.
