Setting up Android Development Environment

Due to the increase in the android users the demand for quality applications is also increasing. As a result more and more programmers are jumping into the field of android development. Developing any android application requires certain development tools. In this android tutorial I am telling you the step by step procedure for setting up android development environment.

Steps for Setting up Android Development Environment

The first step of getting started in android application development is to setup an android development environment. There are two choices:

The first one is using Eclipse IDE
The Second one is using Android Studio

Since Android Studio is still the beta version (that means it is not completely tested) so we will focus on setting up Eclipse IDE

1. The first thing we need to do is installing Java JDK. Download the latest version of java from below link.
http://www.oracle.com/technetwork/java/javase/downloads/index.html

2. The next thing we need to do is install Eclipse IDE (the software we are going to use to develop android applications). Visit the link below and download eclipse for java developers.
https://eclipse.org/downloads/packages/eclipse-ide-java-developers/lunasr1

3. Now we need to is install the android sdk. This sdk is required to run your custom android projects on emulator in order to debug it. You can also use android devices to debug your projects. Download Android SDK from the following link.
http://developer.android.com/sdk/older_releases.html

4. After downloading extract the sdk folder and open sdk manager, select available packages, check the android Repository and hit install selected.

5. Accept all the licenses and download it (if you are an advance user you can select only the required packages).

6. Now we need to set preferences so open eclipse IDE go to Windows > Preferences > Android > SDK Location > Browse the files that we have extracted (SDK MANAGER).

If you are getting any difficulty in above steps then you can check below video tutorial.

4 Best Tips For iOS Application Development

There is no question of the popularity of iOS platform. In the Smartphone world, the iOS platform is the most admired mobile OS. However, it is ranked as the second best platform if their market shares are considered (as, Android possesses over 85% share whereas iOS exhibits around 12% market share).

Tips For iOS Application Development

1. Quite Basic but highly essential requirement: Mac and Xcode

To begin the iOS app development, a Mac device is a must and preferably it should be OS X 10.8 or a higher version, since, it can ensure a smooth and proficient development process. Another basic requirement is the Xcode, an Apple IDE (Integrated Development Environment) that offers an ideal app development framework. It is recommended to install the latest version of Xcode and develop your iOS application with greater precision with the included prolific tools.

2. App Approval From The App Store Is Not The Ultimate Victory

Although, registering a developers account and getting your developed app approved from the Apple App Store is an imperative step, but it is just half the battle. By just getting the approval, your app will not get noticed and generate money. For that, you will need to promote your app with ideal marketing strategies.

For efficiently promoting an application

First of all, streamline your target audience by keeping the prime goal of your application in mind. This will help you make strives for surefire results.
To ensure that your app gets some initial momentum upon its release in the App Store, it is essential to optimize your app for better marketing. The iTunes basically acts as a search engine, and thus can crawl the keyword-rich app content and index them with ease.
Create an online presence of your application to efficiently promote it. Although, the App store facilitates a page to showcase the captivating attributes of your app, but you cant rely only on that . You either create a blog or website to support your application. There you can flaunt all the intriguing features and amazing capabilities of your application.
You can even hire some experts to promote your app over different channels to attract potential customers.
Analytics can help you determine your user behavior, so that you can make strives in the correct direction and improve your app.
Consider your customer feedback. Whether its a positive feedback or negative, accept it. And, try to amend the best possible solution to further improve your app.
Generate as much buzz as you can and gather the attention of journalists bloggers worldwide. This will encourage them to write about your app and thus, will help efficiently promote your app. And, this can definitely do wonders on the launch day of your app.

3. Stay Calm And Be Patient

Developing an iOS application is not a childs play. It could take a few days or a few months, depending upon how complex your application is. From the moment you get some innovative application idea in your head to the moment it gets approved could take a lot of time. In fact, once you submit your app for approval, it is not essential that it will immediately get published. The process could consume a substantial time, thus, it is better to stay patient and watch out the results.

4. Other Essential Key Points For Your Consideration

Plan well while equally balancing both the design and development strategies.
Keep the targeted audience in mind while developing an application. This way you will be able to develop something useful that can best cater to the needs of your potential customers.
Dont wait for application development to be completed, you can start promoting your application alongside the development process. This way you can create a good market base for your application.
Most importantly, dont forget that you are targeting the touch-screen devices. Think of the app functions and features while keeping that in mind.

Final Thought

The aforementioned useful tips and facts can help you ensure a great iOS application development with an optimal approach. Go through these tips and prepare yourself for the forthcoming challenges that you might face during the development process. Create a remarkable application and promote it globally to enhance your business values and generate greater ROI.

Swift A New Programming Language Introduced by Apple For iOS and OS X Development

Swift is an object-oriented programming language for iOS and OS X development which is recently introduced by Apple at its WWDC 2014. It is intended to coexist with Objective-C, the current programming language for Apple operating systems. Swift is designed to be more resilient against erroneous code. It is built with the LLVM compiler.

Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works. On June 2, 2014, the WWDC conference app became the first publicly released Swift app.

Example code

let people = ["Anna": 67, "Beto": 8, "Jack": 33, "Sam": 25]

for (name, age) in people {

println("(name) is (age) years old.")

}

Swift: A New Programming Language Introduced by Apple For iOS and OS X Development

Some awesome features of Swift Programming Language

Safe

Swift pairs increased type safety with type inference, restricts direct access to pointers, and automatically manages memory—making it easy to create secure, stable software.

Modern

Swift includes optionals, generics, tuples, and other modern language features. Inspired by and improving upon Objective-C. Swift code feels natural to read and write.

Powerful

Take advantage of powerful pattern matching in Swift to write simple, expressive code. Format strings naturally with string interpolation. Use frameworks like Foundation and UIKit directly from Swift.

Interactive

Use playgrounds to experiment with new technologies, analyze problems, and prototype user interfaces

Fast

The Swift compiler applies advanced code analysis to tune your code for performance, letting you focus on writing great apps instead of on implementing complex optimizations.
