you've already posted this post before, a few weeks ago. what's going on?
Anyway, I still think it's weird that Google talks so much about design and keeping the "pure Android" look & feel , yet some of the apps you've chosen do not follow your guidelines, and it's possible to see it even by looking at their screenshots...
Google even talked about it on lectures, that if an app doesn't follow the guidelines, it won't get featured. You've even put a link about Android design, so it doesn't make sense.
Here are some links about Android design that the apps didn't follow:http://developer.android.com/design/patterns/actionbar.htmlhttp://developer.android.com/design/patterns/pure-android.html
Here are the examples:
-Tumblr - no action bar . just 4 tabs.
- Yahoo Weather - IOS style action bar, with title at the middle and buttons on both left and right sides.
- Grand St. - hides the navigation buttons everywhere, doesn't have an action bar and actually have 2 bars with nothing in the middle.
-Pinterest - has an IOS style action bar, with title at the middle and buttons on both left and right sides (search icon on the left?!) .
