this is class for unzipp folder

public class Decompress {

Call Decompress class like this:

String zipFile = Environment.getExternalStorageDirectory() + "/files.zip"; 
String unzipLocation = Environment.getExternalStorageDirectory() + "/unzipped/"; 
 
Decompress d = new Decompress(zipFile, unzipLocation); 
d.unzip();
