We can see that many Android applications have the automatic update function. You can update the software with one click. Thanks to the software package management and installation mechanism of the Android system, this function is quite simple to implement. Let's take a look at it. First, the interface effect is provid
This article is for you to share the implementation of the Android app version update feature.

Android Studio installation Update Ultimate SolutionPreviously wrote a blog that the Android SDK could not be updated, in fact, the same way for Android studio, you can download the network sharing the small software, if the search to the channel after the prompt need to be more fine, you can also choose to
:
public class Global {
Version information
public static int localversion = 0;
public static int serverversion = 0;
public static String Downloaddir = "app/download/";
}
Because this article only focuses on updating updates, in order to prevent too many other extraneous code redundancy, I directly define the method Initglobal () method in Subwayapplication.
Copy Code code as follows:
