Unzip files in Android

You need an app that can unzip files? Android provides the classes that are required for this. Basically you will need to checkout two classes. There are other related classes also which would help you with various other things.

1. ZipInputStream
2. ZipEntry

This example shows you how to unzip a zip file through these classes. If you want to create zip files, that's also possible, but we will keep it for later. In this project, there is a zip file, called ZipTest.zip in the assets folder. It's pretty easy to pick up any zip file on your phone through code. For simplicity, I have placed out test file in the assets folder.

The code is simple enough to need any more explanations. I have put comments in the code. So, do check it out and run it. I have logged the steps on the Activity. The output files are not readable yet in this example due to the format of writing that I have done here (Update: As per rekin's comment, this is fixed now). But you get idea about how to unzip those files. You can find the whole working code here.

Note: There's not much error handling code put in place.
