The entry of smart phones in our lives has made us lean completely towards technology. Mobile phones have now become a necessity mainly because of the new and interesting apps and addictive games which are being launched everyday on the app store. Such mobile app development takes place on various platforms like Android, Windows and iOS and there brings about several features which always makes us stick to our mobile screens.
Various mobile app development companies are gaining importance with the drastic increase in the number of apps and games being launched on app store. There is an increasing demand of new ideas for apps by various businesses. The craze is such that even iOS developers are shifting themselves to developing apps on Android platform. But, the main problem they face is the proper execution of apps in Android app development. So, here we are with some information for iOS turned Android app developers. Hope it turns out to be useful.
Android app development and iOS are quite similar
The developers shifting from iOS app development to Android app development have a misconception that they would have to go through the process of learning a whole new language all together. But, that is not the truth, because you already have those developing skills present in you. Also, being an iOS developer, you must be quite aware of Objective-C or Swift.
While programming with Android, we use the concept of Object Oriented Programming and Java as the base which is similar to Objective-C and Swift. The concept of Delegates, overriding methods and subclasses are also used in iOS and therefore Android app development becomes easy for the iOS developer. Almost all the concepts and logics being used in both platforms are same, it’s just that in Android app development, Java language is used. Therefore, the developer has to get well versed with Java keywords as he will be using keywords like override, implements, extends, etc., and not the ones used in iOS.
Android Studio and X code- Usage Difference
Many a times it is quite annoying to use the Xcode IDE but now there are some major improvements made it in over the last few years. In Android app development through Android studio, some of the Xcode features can also be implemented.
The standard coding practice for overriding methods, subclasses, import statements, etc., used in iOS development is reduced to a great extent by Android Studio by making use of Java keywords. Although both Xcode and Android Studio work quite similarly, there are still some differences in the UI code written in both the IDEs. Where on one hand Android uses separate xml files, on the other hand Xcode uses storyboards and nibs.
Screen size difference
Dealing with screen sizes had been an issue for the iOS developers. This is because earlier they used to deal with only one screen size, whereas in Android app development, developers deal with multiple screen sizes. The later addition of multiple screen sizes in iPhones landed the iOS developers into a problem. But, the Android platform has always been experimenting with the screen sizes and coming up with new additions to it by making improvements in tools. Now, in Android one can not only deal with multiple screen sizes but also with multiple screen densities.
The developers of Android platform seem to be much satisfied with the Android XML attributes and layouts of the file structures than the size classes and Auto Layout in iOS. One can easily see the difference between Android and iOS while using various XML concepts like wrap content and match parent.
