Is there any possibility to hook in a custom maps app into the Android Auto framework? Are there any guide for that?

Musste gerade herzhaft lachen: Sybille Zarg (Eva Löbau) über +Antoine Monot​ (als er selbst): Das ist doch der aus Hangover! ;)

Wobei Junior auf dem Traumschiff auch mal was hätte, aber nicht als Ersatz für Heide Keller, sondern nur zusätzlich.

OK #Google : I like the new gestures on the #Android #Wear devices. But can you please make this scrolling gestures available for APPs and not only in the card view? And can you also include a gesture to swipe away cards with a gesture, maybe for example if you lift your arm in a outbound direction to get rid of a particular currently focused card? That would be very helpful.

Added photos to GDG Rhein-Main TalkTime Xmas Special 2014.

Does anyone know a good data format to save and quickly access graphs to / from binary files? Like a basic graph db would do? I thought of maybe using adjacent lists with pointers to byte indexes within the file. Any hints on this?

Finally I found some time to play around with #Google Cloud Messaging (GCM) in terms of the #XMPP  Stream variant (not the HTTP everyone uses it variant!). What I found was the following: After I finally got a #TLS secured connection to the Cloud COnnection Server (CCS) and got the first response the Google Server closes the connection, no chance to send the authentication XML piece. Any hints anyone?

Btw. +Android Developers : Please correct the typo error on this page: http://developer.android.com/google/gcm/ccs.html . It features a response XML element of "str:features" but the actual answer I receive from the CCS is "stream:features" (which is slightly longer, but makes more sense).

Very cool photo by +Brian Matiash on my #Chromecast. I really like many of the pictures featured there!

So this is why I think #Google 's " #material " design language isn't just a fancy way of new graphical user interface design but maybe a revolution on how we really interact with future devices supporting it!

+Matias Duarte really understands what designing user interfaces mean! (Have a special look at the part of the attached video where he describes the metaphors of the "Desktop").

So why do I think that "material" is something bigger than only a new fancy design with drop shadows and animations? - I think with a new framework like this, it is possible to define depth in graphical user interfaces like an ordinary button on your phone, tablet, watch, whatever has. So it may be possible to produce a device in the future (to be honest: I think Google is working on that with partners!) that can take that information and maybe let a touch display somehow feature the height information for visually impaired persons or at least making inputs on your touchscreens more reliable and therefore enhance accuracy and speed on user input! How may that be done? Imagine a phone vibrating stronger if a virtual material object is closer to screen glass or the other way round. But that doesn't stop there: Imagine a display that really can let the user feel physical depth with micro steps between different pixels. The result may be a really touchable interface that follows human experiences of material interaction in the real world. #Google  even did announce this feedback indirect during their "material" introduction video when the "pixels" came out of the screen. Seriously that was the point that impressed me most about this whole shift and that was the point when most people in the room applauded without even knowing why they really applauded.

Not a big deal, but a logical step into modern touchable user interfaces and a big step into the real goal of touchscreens: Building real world user interfaces without the boundaries of real objects. So "material" can also be considered of a modern fresh way of skeuomorphism design principles.

What do you think +Roman Nurik+Matias Duarte, +Adam Powell. +Marcus Körner, +Martin Gude and all the other user interface interested followers? Am I right on that? Would be interesting to read a response on if I'm right or wrong with my estimation or my thinkings in the area of user interaction principles in "Material".

Math fun on a saturday afternoon. Can someone ecplain how to calculate the distance between two points on a WGS84 ellipsoid to me? Also I'm interested in the vertical difference between a third point and the great ellipse formed by the two other points (also called cross track distance in spherical trigonometry). As third big problem I'm interested in some kind of 'vecor' style direction on that ellipsoid to determin of I'm moving in the opposite direction.

Can someone help? Maybe someone from +Philipp Kandal's team?

I really love the design. Not sure about a missing heart rate sensor, but I would love to see it in there, but because of the design I wouldn’t miss it.
