Java Batch Collection Pea pod website Android app icon and package name _java

The theme of Android theme developers, if you want to replace the Third-party application icon, you must know the application of the package name. Actually want to know the application of the package name is very simple, directly in the browser to open Google Play or pea pod, open an application page, look at the URL you will find that the URL last "/" after the character is the application of the package name!

It is estimated that some people want to use the commonly used icons and package names to get down, so in Java wrote a small program, batch grabbed peas pod "all software" according to the total download volume ranked 1 to 20 pages of the application icon and package name.

All the icons are named with the package name, and there is a PackageName.txt file, which contains the name of the package to be used for the search.

Java source

Share this Java applet, note that if the Web page structure of pea pods has changed (it is estimated that little change), this small program needs to be modified, if you can understand, the modification is very simple slightly.
