September 13, by Bryan Wilde Mobile application development is the hottest thing in the programming world right now. The two most popular mobile platforms are Android and iOS Apple.
Although the numbers tend to fluctuate frequently, it seems that Android has taken the top spot from Apple. If it seems like a popular platform that you should be learning nowyou are right! Not only is Android popular, but it could also become a very profitable platform once you start creating your own apps.
If you already have some experience in Java, you are one step ahead of the curve. If not, consider taking the Java Programming Tutorial to get up to speed in Java programming quickly.
Each android application is comprised of four unique components. Combined, these four components create all Android applications currently available via the Google Play Store or other outlets such as the Amazon App Store. You can learn more about these components in Android Development for Beginners.
Activities In Android, an activity is any single screen with a user interface. A good example is an email application. One activity shows you the inbox, another activity is used to compose new emails, and another activity nandwrite android apps you to read emails.
For the uninitiated, this may seem like extra work. Actually, this makes your job as an Android programmer much easier because the modular design allows you to change one aspect of the application without affecting the rest.
For instance, you may want a different color scheme when users create a new email that differs from colors used in the rest of the app. Using activities makes this a very simple task. Services Services run in the background. They are responsible for long-running operations or performing work that does not require user interaction.
Services do not have a user interface. Music players often run as services so the music will continue to play in the background even when the user switches to a different screen.
Another popular service implementation is retrieving background data. For instance, if you ever use Gmail, you are familiar with push notifications. A service running in the background checks for new mail periodically without manual intervention from the user.
This is a perfect example of a service in action. Content Providers Content providers help manage application data. In the Android operating system, data can be stored within the file system, in a separate SQLite database, on the Web, or in other storage locations such as a microSD card.

This application is able to read or write information to the contacts database using content providers. Broadcast Receivers This component is responsible for responding to system wide broadcast announcements.
Although most broadcasts are initiated by the Android system, your application can also create broadcasts that let other system applications know what is going on.
This could be as simple as a status bar notification or it could start another activity or service automatically. Unique Android Components There are numerous reasons why Android is a unique platform that allows developers of all experience levels to successfully create functional applications.
In fact, there are way too many to discuss here.
However, one of the most important Android features that allows you to start building complex applications quickly is that your application can start activities and services of existing applications very easily. If your application needs to use the camera so a user can take a picture, there is no need to write the code for the camera because it already exists.
All you need to do is start the activity for the camera application and your application will automatically have full control of the camera and any pictures that are recorded using the camera activity.Read&Write for Android is an easy to use alternative keyboard with integrated features to help you with writing content such as emails, social media, or interacting with online forms etc.

Although Apple and Google champion specific programming languages for mobile development (Objective-C/Swift for Apple’s iOS, and Java for Google Android), independent developers spend a lot of time figuring out how to build iOS and Android apps using other programming languages.. Some alternative languages include C# (Xamarin) and Pascal (Embarcadero-Rad Studio).
