One thing that apparently already is working its way out in the open (unlike the mythical Nexus One Froyo update that's only reaching a blessed few) is the new crash report tool for Android applications. We got a look at this during the keynote on Thursday at Google IO, and it's a nice little feature. If an app crashes on you, tap the "Report" button. Then you can send your system data directly to the developer, so they can figure out what happened. You also can leave "Feedback." Try to keep that constructive, huh?
Developers then get the bug reports and can act on them. Below is what we see. Pretty cool, huh? I've got the report feature on the Droid and Nexus One, but not the Evo 4G thus far. Thanks, @macprv!
