Applications:-

These are the basics of Android applications:

• Android applications are composed of one or more application components (activities, services, content providers, and broadcast receivers)
• Each component performs a different role in the overall application behavior, and each one can be activated individually (even by other applications)
• The manifest file must declare all components in the application and should also declare all application requirements, such as the minimum version of Android required and any hardware configurations required
• Non-code application resources (images, strings, layout files, etc.) should include alternatives for different device configurations (such as different strings for different languages)

Google, for software development and application development, had launched two competitions ADC1 and ADC2 for the most innovative applications for Android. It offered prizes of USD 10 million combined in ADC1 and 2. ADC1 was launched in January 2008 and ADC 2 was launched in May 2009. These competitions helped Google a lot in making Android better, more user friendly, advanced and interactive.

How to get started with android:- Check out our guide on how to set up an android phone for an idea of what you’ll need to do to get started. One of your first tasks will be to create a Google Account (or sign in with an existing one). This gives you email functionality and also provides a great way to backup your contacts, save your files online and so on.

The benefit of this is that if you lose your phone, all of your numbers and important data will be saved. The next time you get an Android phone (or other device) and sign in with your Google Account, all of your contacts and numbers will be displayed in your new phone’s address book immediately. No need to transfer them over or back them up anywhere else.

In fact, you can sync your personal info across all kinds of Android devices. This includes favourite websites, calendar entries and purchased apps. This is all backed up seamlessly, in the background.
