None of that has anything to do with "automatically testing and rating applications in regards to speed, battery usage, and force closes". "Automatically testing" assumes that you (and I do mean *you*) have the ability to create a driver that can exercise arbitrary applications, with no prior knowledge, precisely how users will use them, and somehow come up with "speed, battery usage" data that has real-world ramifications. What you describe in this message is not "automatically testing" anything. What you describe in this message is not bad information to gather (assuming it is opt-in on the part of the user), but it is not "automatically testing". -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.5 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
