What are APK files and why is there a need to download such files? APK files are meant for smartphones for example android smartphones. They're app files, as well as can be used to install applications on mobile phones.

The most popular smartphones these days are, of course, Android smart phones. Applications may be downloaded into these phones through a channel referred to as the Android Market. Android Market, a web page owned by Google, is a marketplace that distributes smartphone apps.

Often, for some reason, mobile phone owners are not able to download apps directly from the Market. For example, some models are not supported by the Market, so users can not login and download directly. But this will not mean that the phone is incapable of running applications. Here is where APK files come in.

APK programs are actually application files. In Windows, we have been all familiar with executable (EXE) files. They function in a similar manner. Whenever you click on an APK file, you are launching the installer for the application. The app can then be installed directly on the device. So if you cannot access the Android Market for some reason, then your only option is to look elsewhere.

Obviously, for security reasons, you should only download and install these files from trusted sources. Before installing, ensure that your particular have modified your settings to allow app installations from unknown sources. So where can you find reliable app. files?

Such files can be created by making a backup of existing apps. Most free apps which are available publicly may be backed up into an APK file. The file may then be re-distributed to be installed on other smartphones. Some developers release APK installers for the benefit of all users. These files tend to be released in apps-related blogs and forums. You shall find a great deal of APK installers in developer forums.

Oftentimes, an app might be updated, causing the smart-phone to crash. It means that the updated app is no longer usable. Since you can't revert back to the older version (there's absolutely no option to do that), you will be forced to uninstall the new app and look for the old version. Even when you have access to the Android market, the old version may no longer be available. This really is the time to request or search for an apk game files file.
