Be patient from 00:10 to 00:24 as I run the program.
Here I wrote a small Robotium project to test Skype apk I got from Google Play after properly processing it. No source code is needed. I clear previous user name and enter new username/ password, go to contact, call Echo / Sound Service, turn on speaker to make it louder, take a screenshot at exact 5 seconds (or any time you want), then end call, go back and log out.
The screen shot is in Robotium-Screenshot folder on sdcard. You can add time stamp to the file name in Robotium so you can take a lot of screenshots.
The only drawback is that the password will show up on device, whether you use enterText() or typeText(). I think I might have a solution but I haven’t try it out.
