Google created the I/O 2013's Android Sessions video playlist, as well as playlists for each developer category: design, develop, and distribute (embedded below):
In other Android news, Google unveiled Samsung Galaxy S4 on Google Play store during the I/O, today, Sundar Pichai, Google's SVP of Android, Chrome, and Apps, at the D11 Conference, revealed that HTC One is getting a Nexus edition too, and it will be available on Google Play US for $599, $50 less than Samsung's flagship starting June 26.
"The unlocked device will run on both AT&T and T-Mobile in the United States with support for high-speed LTE data on both networks. This 'Nexus user experience' version will contain 32GB of built-in storage. Much like the special edition Samsung Galaxy S4 unveiled during I/O, Google will be directly handling future software updates."
HTC One Nexus Edition of Google Play will run stock Android. For example, "it will have an infrared blaster that can't be used by Google's software because the stock Android 4.2 doesn't support IR. It's likely that a future Android update will add native support for infrared sensors."
On the other hand, Samsung has launched Galaxy S4 mini, that comes with a 4.3-inch qHD Super AMOLED display, 107g weight, a 1.7GHz dual core processor, and runs Android 4.2.2 (Jelly Bean) out-of-the-box.
Other features include: 8GB Internal memory (User Memory approximately 5GB) ＋ microSD (up to 64GB), 1.5GB RAM, an 8 megapixel rear camera and 1.9 megapixel front camera.
