6) Application and Market
One of the factors that made ​​the success of Android is the application most useful and free to be developed for this operating system. Apps on Android can be written in Java, Objective-C and some other languages ​​in the SDK (Software Development Kit) was released Google. 's Android applications have access to much more of the application system operating system used on its rivals - iOS. In addition to the calling application (Phone), Messaging (Messaging), Browser (Browser) built by Google, users can download the app from the Market functionally equivalent. These applications are mostly free and sometimes they have the look and performance even better than apps available. Many software developers such as Adobe, Microsoft and writes the software for Android, such as Photoshop Express, Microsoft Bing, ...

Market is "fair" for Android app. The programmers who wrote after finishing his program, through a series of stages registration, censorship, their applications will come to people through distribution channels Market. On the Market has two types of applications, such as toll free. The application is distributed free to all nations, while the application fee appears only in a certain areas of the world.Number of applications on Android is huge and growing. However, due to Google's censorship process is not so strict, some applications "junk", or deceptive applications applications "Virus" (created message to the user and amortization charges, ...) still appear pretty much on Market, not to mention the bad software content, adult content and full attendance. This is the big bad of Market versus the App Store. Therefore, before you install the software, users should check out the features that exploit application on the phone (such as SMS, Network, File, ...). If this function is not suitable for the introduction of the software (such as: application form which should see the message and exploit calls) is 90% which is malicious applications.

The interface of the application are listed Market leading software

Another highlight of Android compared to other mobile operating systems is the ability to support Flash.Flash version 10.1 full version Adobe has been designed for Android, so those using Android version 2.2 and above will have the experience of Flash as on the computer. However, the use of Flash costing the battery pretty fast, the machine becomes hot and slow than normal. This can be found on Android 2.2 devices have low configuration (devices segment cheap). On older versions of Android, users can use Flash Lite to browse the web, but they are not really good and not the device is also equipped with Flash Lite.
