There have been a gradual increase in number of sensors that are being built into smartphones, in order to make them more intuitive. This has pushed the boundaries for more alternative methods of interaction with the smartphone. Device gesture recognition has been one such aspect that has garnered a lot of interest of developers. The Accelerometer Actions used in iPhone application development is one such framework which takes in accelerometer actions from the controller and generates corresponding callbacks as per defined in the classes.
This little framework is very easy to integrate into the source code of the application and opens a whole new dimensions of interactions. Developers can use these enhanced interactions in the iPhone and the iPod Touch applications to add more functionality. What is more important to understand is the fact that these group of classes have a very little footprint and does not pose a lot of burden in the performance of the application.
The idea is very simple and involves the application to respond to specific motion that take place during the course of a specific gesture. For example, you might tilt the device in a particular direction to incorporate some action. Currently Accelerometer Action Framework supports seven gestures that can be used by the iPhone app developers. Rotation of device sideways in a clockwise direction.
• Rotation of device sideways in an counter-clockwise direction.
• Moving the top part of the device from right to left.
• Moving the top part of the device from left to right.
• Moving the top part of the device in the upward direction
• Moving the top part of the device in the downward direction
• Strongly shaking the device
Although all of these gestures can be pre-defined in classes and then called on an event occurrence, they are only available in the portrait mode and no support is yet available for landscape mode. When the user invokes any of the following gestures, the accelerometer registers a constant acceleration because of the gravity. This action can then be corresponded to the group of classes defined in the code.
A simple example of using this framework could be gesture based call management. If someone calls you, with your iPhone sitting on the table, a simple action to silent the phone using the gesture “Rotating the device from left to right like if you are turning a key to open a door” can be invoked. So when the iPhone is rotated in clockwise direction, the call management service would silence the ringer. Another example would be tilt to zoom in or zoom out of picture. There are a lot of similar real world applications of using this accelerometer based action framework, which developers can utilize.

Apps, Apps everywhere but where is the security! We all are crazy for mobile applications our pricey and high definition smartphones and tablets. But somewhere have we ever thought we are downloading an app giving them access to sync with our device having personal information too so are they secure enough to give them that access.
Hardly anyone think over this. However this is the responsibility of mobile application developers to overcome all security loopholes in their apps. As now applications are not limited for entertainment purpose only. May enterprises are also adopting mobile application for their internal tasks and performance efficiency. So, the need to give priority to security heightens with so companies putting their data at stake for these apps.
The perception of a native app as a secure app is not acceptable. Further, encryption of apps by mobile apps developers to authenticate users is also not enough. However, ignoring such security issues may lead to serious consequences like financial loss, reputation tarnish, public shame, twitter shame etc.
Whenever you hire developers or outsource your app for development always make security integration as the foremost requirement. It is because mobile apps will somewhere use your backend services so don’t take a chance. It would be advisable to be sure to consider the following six security properties to have a secure app without any threat of data mishandling.
Android now flaunts some of the most skilled and talented developers across the world. The all credit goes to the enticing Android application users and Google Play. It is also an escape place for all mobile apps developers from Apple’s strict App Store and absence of any defined approval process makes Google Play a cool place to hangout for mobile apps developers.
It also needs much reduced investment of time and money into Android software programming. However, inspite of all luring and fascinating features of Google Play for mobile application development there are many obstacles between an Android app developer and a top application. The causes of such hurdles are the notorious fragmentation of Android on both Hardware and Software.
To overcome this fragmentation there are some top platforms that can actually make Android app development task incredibly easy. The platforms consists of libraries and services which offer developers concrete foundation of Android applications that would otherwise call for plenty of hours from developer.
Here are 4 ingenious Android platforms:
Mozilla famous for web browser Firefox and Thunderbird email client is having ambitious plans for agnostic mobile application marketplace. Mozilla has a vision of future mobile application which seems like drawing blood from the heart of internet. It is completely different from what we already practices with native mobile application development on Apple, Android and BlackBerry.
According to the sources, Mozilla is planning just another part of internet’s evolution. The web is meant to be redesigned. Mozilla has a plan to teach web the secret behind making awesome applications. This will be done through Web Runtime.
To make these web applications easy to locate, buy and use, Mozilla is planning to offer them through App Marketplace. The business model may look similar to that followed by Apple, Google and RIM mobile application development services; the basic difference for developers and end users is a non issue.
In development of an application and launching it in market there is no need to navigate complex approval channels which are seen in case of iTunes app store or BlackBerry app world. This business model offers benefit for end users in which they don’t have to worry about looking for compatible platform again. It means that the application bought by you or downloaded is always with you no matter what device you are accessing to use it. Thus, it forms a potential shift in table or mobile computing.
While everything about this sounds very fabulous and Mozilla’s dedication to open computing will not permit companies to deploy group or user specific applications. Anyone can download anything from their app store keeping in mind no violation of laws.
Mozilla will provide source code required by individuals and organizations to construct their own private application warehouse which will restrict it to be accessed by authorized users only.
