Excited about my cameo performance for the new Android Development Patterns series, coming soon! #BuildBetterApps

It turns out that mixing instant coffee with steamed milk doesn't taste all that good, even with a bunch of sugar.
 
100 days of Google Dev, Episode 61/100

Every Android app should have, at its core, a solid foundation to build on.

Android Development Patterns will teach you how to build better apps by explaining the fundamental components of Android development, the reasoning behind them, and best practices for using them in your app.

Using your existing Android knowledge, +Timothy Jordan, +Joshua Gordon, and myself will show you how to extend your existing apps to these new platforms without having to reinvent the wheel.

I personally worked on the Android Wear and Android Auto parts, and it was a lot of fun to create the material for this.

Introducing the #GoogleBeaconPlatform and the #Eddystone BLE beacon format. Read more about it in this blog post:

If you want to know where the Eddystone name comes from, check out this article: https://en.wikipedia.org/wiki/Eddystone_Lighthouse

Created a proof of concept of this 10 years ago! Shame BLE wasn't around then, the J2ME was fun too... so many applications for this!

Useful tip on using adb to pipe over binary data.
 
adb shell and piping binary data

If you're unaware, running "adb shell" creates a pseudoterminal. This means that all LF characters are rewritten as CRLFs. If you're piping binary data back to your local machine, this will corrupt stdout.

For example, this results in a corrupted PNG file:
adb shell screencap -p > test.png

I was looking to fix this in adb, then noticed it was already done last year. There's an unadvertised exec service that bypasses the creation of the pseudoterminal. Invoke as follows:

adb exec-out screencap -p > test.png

Change was made by +Jeff Sharkey 

https://android.googlesource.com/platform/system/core/+/5d9d434efadf1c535c7fea634d5306e18c68ef1f
Add "exec" service: shell commands with no pty. To facilitate device scripts that want to read/write binary data from the host side, this change introduces a new "exec" service that behaves like "shell" but without creating a pty, which would otherwise mangle binary data.

Wow! The pictures keep getting better every day now! We only had blurry images just a few weeks ago, and now we have these amazing shots. I'm going to be waking up at 4:30 am PST on Tuesday to watch the live New Horizons flyby coverage, where we will see the best photos of Pluto that will probably be taken in our lifetimes. Decades of design and construction, 9.5 years of travelling over 3 billion miles, and now it is time to make it all work. The probe cannot communicate over the radio and take pictures at the same time, so the flyby happens fully automatically. If anything goes wrong or if it has a collision, we might never hear from the probe ever again, and we will never know why. So now we wait.

Some of the finest hardware and software engineering goes into projects like this. It is truly the pinnacle of human achievement. And it eventually becomes amazing technology that benefits us all at home as well.

Good luck New Horizons, you are all alone out there, but I know you can do it. All of us on Earth are looking forward to your first transmission on the other side, and then on to the Kuiper belt for more adventure!

TV Schedule:
https://www.nasa.gov/multimedia/nasatv/schedule.html#.VZ9WwZNVig0

(Update #1) Seems like I might not be waking up at 4:30 am PST after all ... here is a better schedule that indicates the best picture might be at 8:15 pm PST. http://www.planetary.org/blogs/emily-lakdawalla/2015/06240556-what-to-expect-new-horizons-pluto.html

(Update #2) No photos came out at 8:15 pm PST, so it looks like they are going to hold on to releasing them until the flyby press conference at 4:30 am PST tomorrow. So we're back to waking up early!

#PlutoFlyBy
At 7:49 AM EDT on Tuesday, July 14 New Horizons will zip past Pluto at 30,800 miles per hour (49,600 kilometers per hour), with a suite of seven science instruments busily gathering data.
