Hybrid App development A hybrid application (hybrid app) is one that combines elements of both native and Web applications . Native applications are developed for a specific platform and installed on a computing device. Web applications are generalized for multiple platforms and not installed locally but made available over the Internet through a browser. Cordova Apache Cordova is an open-source mobile development framework. It allows you to use standard web technologies - HTML5, CSS3, and JavaScript for cross-platform development. Applications execute within wrappers targeted to each platform, and rely on standards-compliant API bindings to access each device's capabilities such as sensors, data, network status, etc. Web applications cannot use native mobile functionalities by default. This is where Cordova is coming in. It offers a bridge for connection between web app and mobile device. By using cordova we can make hybrid mobile apps that can use camera, geolocation, file ...

PhoneGap Framework Building applications for each platform–iPhone, Android, Windows and more–requires different frameworks and languages. PhoneGap solves this by using standards-based web technologies to bridge web applications and mobile devices. Since PhoneGap apps are standards compliant, they’re future-proofed to work with browsers as they evolve. The PhoneGap framework was contributed by the Apache Software Foundation (ASF) under the name Apache Cordova and graduated to top-level project status in October 2012. Through the ASF, future PhoneGap development will ensure open stewardship of the project. It will always remain free and open source under the Apache License, Version 2.0. To develop apps using Phonegap, the developer does not require top have knowledge of mobile programming language but should know languages like, HTML, CSS, JScript. PhoneGap takes care of rest of the work, such as look and feel of the app and portability among various mobile operat...

What is a widget?  In Android , the word widget is a generic term for a bit of self-contained code that displays a program, or a piece of a program, that is also (usually) a shortcut to a larger application. We see them every day on web pages, on our computer desktop and on our smartphones, but we never give too much thought into how great they are. Widgets first appeared in Android in version 1.5, and really gained traction thanks to HTC's Sense-flavored version of the operating system. Prior to the release of the HTC Hero and our first taste of HTC Sense, widgets were functional, but pretty bland in appearance. Since then, the people making our phones and independent developers alike have done some marvelous things with widgets, and it's hard to imagine using Android without them. Android support to implement widgets for both, the home screen and the lock screen. Common Types of Android Widget Widget typically fall in one of the following categories 1. Inform...

WiFi is a technology for wireless local area networking with devices based on the IEEE 802.11 standards. Devices that can use Wi-Fi technology include personal computers, video-game consoles, smartphones, digital cameras, tablet computers, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet via a WLAN and a wireless access point. Such an access point (or hotspot) has a range of about 20 meters (66 feet) indoors and a greater range outdoors. Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometers achieved by using multiple overlapping access points. Android allows applications to access to view the access the state of the wireless connections at very low level. Android provides WiFi API through which applications can communicate with the lower-level wireless stack that provides WiFi network access. Almost all information from the device supplicant is available, includ...
