Android programming implements the method of copying compressed database files to the installation directory _android

This article illustrates how the Android programming implementation will copy compressed database files to the installation directory. Share to everyone for your reference, specific as follows:

public void Copyzip2datadirectory throws IOException {
  FileOutputStream outputstream = null;
  Assetmanager Assetmanager = Context.getassets ();
  InputStream InputStream = Assetmanager.open ("Test.zip");
  Zipinputstream ZiS = new Zipinputstream (inputstream);
  ZipEntry entry = null;
  while ((entry = Zis.getnextentry ())!= null) {
   outputstream = Context.openfileoutput (Entry.getname (), Context.mode_ PRIVATE);
   byte[] buffer = new byte[2 * 1024];
   int len =-1;
   while (len = zis.read (buffer))!=-1) {
    outputstream.write (buffer, 0, Len);
   }
   Outputstream.close ();
  }
  Zis.close ();
  Inputstream.close ();
}

I hope this article will help you with the Android program.
