No Project to Select for Build Target in Android Test Project

Question

I followed the instruction for "Hello, Testing" tutorial but could not found any project to select for build target at this instruction "Test Target: Set "An existing Android project", click Browse, and then select "HelloAndroid" from the list of projects."

Ok, let type the location of an existing project: ~/workspace/HelloAndroid, the Finish button still not enable.

I'm using Android SDK 2.2. and Eclipse Hellios, Java SDK 1.6 on Ubuntu 10.04

What should I do to move on this Hello Testing tutorial?
