Settings in the Android-applications

Interested in the topic of development under Android. I am writing a small application. Faced with the fact that not fully understand how to make settings for the application. A little Googling and found an article that helped to understand. Decided to translate the article for the Russian-speaking community, including some comments to the original. 

Options are an important part of applications for Android (and not only on Android - hereinafter translator's note). It is very important - allow users to change application settings, depending on their preferences.

There are two ways to work with the settings in Android - you can create a file in a directory preferences.xml res / xml, or work with the settings from your code. In this article I'll show you how to work with the settings using preferences.xml file.
