For comparison, here's before and after the action bar overlay change. It's quite impressive (if I may say so myself) how much better it looks without a heavy block of color hanging above these beautiful high-res promo images. Not to mention that you have just that much more vertical space above the fold for your content.
I don't think that immersive mode would necessarily work for something like browsing, searching and buying stuff in the store. It's not like you're spending time on the same canvas like in books, newsstand or even maps. But I'll leave that to our designers.
+Blendi Krasniqi It looks like it has a ridiculously tall action bar. No thanks.
+Kirill Grouchnikov This looks very good in your screenshots, but I've seen many lighter pics on Play Newsstand on the top which almost hide the buttons up top. Is there a dynamic way to change the color of the buttons based on the background?
+Abhilash Bingi - if you write a bunch of image processing code on the device side. Also, nothing guarantees that the top part of the image is uniformly colored, so you'd need to "protect" each icon separately. Which is why we're using translucent black gradient along the top edge of the hero image.
You can do static translucency gradient values, or you can sample pixels along the top part of the image and make those values dimmer if you detect that the image has too many bright pixels or too much variation in brightness.
In the real app, I don't see any overlay. But when you scroll, the cookies background fades in, so vanished icons become visible again. Also, on all screens mine shows the overflow menu at the far right. It looks nice, then scrolling makes it look practical.
+Kirill Grouchnikov Is it possible that the translucent action bar does not work for some media outside the US? Can't seem to find it for books and movies in Germany, although music and profile work fine.
