Spell check is of the most common programs used to identify words in a document that may not be spelled correctly. Today, one need not carry a dictionary to self spell check. The age of mobile technology has given rise to a number of applications that incorporate the spell checking functionality. Android offers developers a spelling checker framework. In order to implement the spell checking feature, developers need to make use of the SpellCheckerSessionListener interface.

The term proximity is basically the fact, condition or position of being near or close by in space. A proximity sensor is a device capable of detecting presence of nearby objects without any physical contact. Some of the Android phones in the market today come equipped with a proximity sensor.
Through this post, we will learn how to use a proximity sensor in Android. As mentioned in the developer's guide, the Android platform provides a sensor that lets you determine how close the face of a device is to an object (known as the proximity sensor).

As Android developers, we often need to call web services in order to fetch data from a server. We also need to parse the data for displaying it on the user interface. There are various parsers available that enable developers to retrieve data efficiently from a web service. JSoup is one such open source library that provides an API for extracting and manipulating data. Basically, it is an HTML parser used for working with various HTML elements, attributes etc.

Android provides the WiFiManager class for managing all aspects of WiFi connectivity. It is used to to define the names of various Intent actions that are broadcast upon any sort of change in WiFi state. Through this post, we will learn how to display a list of available WiFi networks to which an Android device can be connected. The list can be viewed and updated, and attributes of individual entries can be modified.

As developers, we often need to create applications that can share data with other applications residing on the Android device. A content provider is similar to a database where one can query it, edit its content, as well as add or delete content using insert, update, delete, and query methods. As mentioned on the developer's page, Content providers manage access to a structured set of data. They encapsulate the data, and provide mechanisms for defining data security.
Hello friends!
In the past we have discussed about creating and displaying a basic ProgressBar in Android. A ProgressBar, as the name suggests is basically used to indicate the progress of an operation. By default the progress bar is a spinning wheel (an indeterminate indicator). However, one can also create a circular ProgressBar by applying certain custom attributes. More such styles can be found over here.
In order to create a circular progress bar we need to add a new XML file in the drawable folder.

It's time for another cool Kivy tutorial. In this one I will explain how to use the Clipboard core module to copy text from a Text Input widget. The text thus copied will be applied to a Button, displayed in our layout.
Kivy provides a core class for accessing the Clipboard. It is used mainly to copy some data so that it can be used somewhere else. On the other hand, the Text Input widget provides a box of editable plain text.
Hi guys!
Lightbox is a well-known JavaScript technique used to display images or any web content using modal dialogs. Not too long ago, the lightbox plugin was written in jQuery that allowed developers to modify the code and come up with new plugins that carry out the same task.
Colorbox is one such jQuery plugin that we can use to implement a lightbox. Through this post, I will try to implement a sample HTML page that displays a lightbox using the Colorbox plugin.

Today's Kivy tutorial talks about one of the existing complex UX widgets called TabbedPanel. The TabbedPanel widget manages different widgets in tabs. It consists of a header area for the actual tab buttons and a content area for showing the current tab content. Before you begin implementing this widget you need to understand the concept of a TabbedPanelHeader.
What is a TabbedPanelHeader? An individual tab is called a TabbedPanelHeader.

In my previous Kivy tutorial I talked about the Carousel widget and the AsyncImage class that one can use to display and load images respectively. Today I would be talking about the Graphics module of the Kivy framework! 1. Graphics (kivy.graphics) From the Kivy documentation, the Graphics package assembles all low level functions to draw an object.The entire package is compatible with OpenGL ES 2.0 and has a lot of rendering optimizations.
