Google has finally launched a competitor to Facebook's

It looks pretty flexible. What do you think?

+Jason Brown Oh jeez... yeah, that is a pain. I thought it was a) the same thing and b) still around. I guess the concept is still there though...

Update: Wait, wait, wait... the "App Engine backends" they refer to not being confused with are for doing large compute tasks in the background. They aren't at all related to generating APIs and clients... I'm pretty sure the 2012 I/O video I linked is still this product.

Great tip
Today’s #AndroidDev #Protip from +Nick Butcher and +Katherine Kuan is on a smoother app launch experience.

On app launch, Android displays a simple preview window (based on your activity theme) as an immediate response to the user action. Then the preview window crossfades with your actual UI, once that has fully loaded. To ensure a smooth visual transition, your activity theme should match your full UI as closely as possible. The below image shows how the experience can be jarring if not handled properly. 

For example, if your activity does not require an action bar, then disable it in your theme so that it doesn’t briefly appear in the preview window. To do this, use or extend an activity theme with no action bar. You can also override the background color of the window, if applicable, to better match your full UI.

<style name="AppBaseTheme" parent="android:Theme.Holo.NoActionBar">
    <item name="android:windowBackground">@color/red</item>

When using an action bar in your activity you can tweak it’s displayOptions such as showing or hiding the title or logo to achieve a smooth app launch. For more info on this refer to the documentation & Action Bar API guide

Don’t be tempted to use this functionality to build a splash screen as the preview window is shown whenever the activity is constructed i.e. after configuration changes such as rotating your device; not just on the first app launch.  Do use this to create a smooth experience for your users, minimising jarring transitions. For more info on gorgeous app launching see this blog post by +Cyril Mottier.

Lenovo Buys Motorola from Google

"Google will retain ownership of the vast majority of Motorola's patents".

Remember when Google said the Motorola acquisition was about more than patents? Yeah...

They probably got to keep a bunch of talent too, which is more important than patents in my opinion

How do I mirror Glass to a TV?
I'm doing a presentation about Glass and I need to mirror the display to a TV. What's the best way to do that?

(apologies if this has been asked and answered. I couldn't find it here.)
Jenny Murphy's profile photoDavid Shellabarger's profile photoJason Salas's profile photoRob Rusher's profile photo
Update: The hackathon was great. We had 4 teams of 6 do presentations and almost every team had a working Glass app at the end of the 30 hours. We used Droid@Screen to demo. Since most of the demos required that Glass wearer to move around we opted to using the Mirroring feature of the MyGlass app so there were no wires directly connected to Glass. This made the lag time almost unbearable but it was the best we could do for the hackathon.
I really wanted to try out MiraCast from the phone (showing Glass) straight to the projector but our projector didn't have HDMI and we didn't have enough adapters to get that to work.

Hangouts 2.1 for Android: SMS improvements and a homescreen widget

Today we’re launching the newest version of Hangouts for Android, rolling out to the Play store ( over the next few days. Highlights include:

- Merged conversations: SMS and Hangout conversations with the same recipient are now combined into a single conversation. You can control whether you want to send a message via Hangouts or SMS with the flip of a switch, and different message types will be easy to tell apart in the conversation. Of course, you can always merge and unmerge conversations if you’d like.

- Simplified contact list: now there’s two main sections in contacts — People you Hangout With, and Phone Contacts — making it simpler to navigate, and easier to use for SMS.

- Homescreen widget: add the Hangouts widget to your homescreen for quick access to your recent conversations.

- Performance improvements: today’s update includes better quality video calls, as well as improved SMS and MMS reliability.

The new version will be available in the Play store ( this week, so download or update and let us know what you think!

Looking forward to the feature where my hangouts become searchable in gmail, and where it doesn't require a 3rd party app to make backups.

Pro Tip for Watching the Olympics Online

You don't have to have Cable to watch the olympics online. You can watch them on for 30 minutes at a time. You just have to clear your cookies every 30 minutes and you can watch as much as you want.

I imagine incognito tab in chrome would do the same as well.

Chromecast is now open to developers

Starting today, the Google Cast Software Development Kit (SDK) is available for developers who want to build Chromecast support into their apps and websites. 

For the non-developers, that means even more of your favorite movies, TV shows and music will become available on Chromecast over time. Just be on the lookout for the cast button in your favorite apps and websites, and stay up to date about apps that work with Chromecast at

They pulled a Wii-U and ended up delivering a console before 3rd parties had access to it. Seems like a poor execution on google's part.
