android test automation, but only apk file available

From this video, how he could do it? http://ift.tt/18WC6yF

For that I have

1. Resigned the apk file with debug sign.


2. Created a test project based on existing project in Eclipse and then change the android:targetPackage field to the apk's pocket name.


3. Change the pocket name in project's src folder to the apk's pocket name.

They all don't work.

What more to do for it? Thank you.
