Today we are rolling out an OTA update to "sprat" Android Wear devices from Samsung that were stuck on a very old LWX48P firmware and old Google Play Services. These devices were sold with a non-standard "dev-keys" firmware, whereas normally devices use "release keys" firmware. dev-keys devices do not receive updates for anything. We have added a special OTA update that converts the LWX48P devices from dev-keys to the proper release keys LWX48P, and that will then allow the OTA update system to bring the watch completely up to date.

For users, it will take a few days for the update to be made available to everyone. After applying the update, you will need to factory reset and pair the watch up again, and then it will apply the latest updates that were previously skipped.

For developers, you will need to wait for users to apply the update and then you should see a drop in the number of old sprat devices showing dev-keys and old versions of Google Play Services. With this update, any user will have an easy to use path to get back to receiving regular updates.

+David I don't think the device is for sale any more, but we want to correct the firmware on the device so that users can get security updates and also Google Play Services updates, since a lot of functionality is actually updated in there. These dev-keys devices were not able to install apps from Google Play due to them being so old and out of date.

This article reminds me that I need to take some time off to spend a day like this at home relaxing and making breakfast ... I love breakfast ...

https://blog.mousereeve.com/a-suggestion-on-how-to-spend-a-day-at-home/
Or: A Breakfast Manifesto Here's what you do: Wake up in the morning, put on a comfy sweater, and make a pot of tea (or coffee if you're into that). Make yourself a light breakfast -- biscotti or a scone, toast with jam. Sit down, stare out a window, drink

This is good news for Hyundai owners ... Hyundai have released an update that adds Android Auto support to some existing vehicle models from 2015 and 2016: https://www.cnet.com/roadshow/news/hyundai-expands-diy-retrofit-for-apple-carplay-android-auto/

If you have the internet and an SD card reader, you can get the retrofit applied in just a few hours.

Android N now includes support for Scoped Directory Access, which allows your app to get read and write access to a directory (and not just a file like in M) on SD cards and USB attached storage! +Ian Lake created a great video to explain more about this, and there is more information here: https://developer.android.com/preview/features/scoped-folder-access.html

So if you are producing some kind of media playback app, perhaps on Android TV, you should look into this, so you can support files that users have on their local removable storage.
 
Scoped Directory Access in Android Nougat

Scoped Directory Access is new to Nougat and provides an alternative to the storage permissions with two important differences:
- It gives you access to only a specific directory - don’t request access to the entire primary storage if you only need the pictures directory!
- It gives read and write access to SD cards and USB attached storage!

Polar just announced the new M600 sports watch powered by Android Wear. If you look at the specs, you will see it has a 1.3" display, with 240x240 pixel resolution. As a developer, you will want to test your apps to make sure it supports this display correctly. We have already updated Android Studio so it contains an emulator profile "Android Wear Square, 1.3", 240x240, hdpi" which you can use to test this.

Polar M600 sports watch powered by Android Wear™ is Polar’s first sport-optimized smartwatch.

+Francois Roy most Samsung devices are already updated, this OTA just fixes those devices sold with dev-keys. I don't have any information about what devices will support Wear 2.0 however.

I've been hearing some reports that the provided Android Wear emulators are not 100% matching the displays of all currently available devices on the market. We have made a lot of improvements to the emulators with recent Android Studio updates, and in theory, we should have a suitable resolution, density, and shape profile for every device. If you know of a device which is not accurately represented, or if you have a code sample that renders differently between device and emulator, I'd be very interested in seeing it, I can then file bugs and get it fixed. Please share your feedback in the comments below. Thanks!

Now I use as suggested by friends:
Get display width when window insets applied, then calculate font using only px. That makes text to be exactly the same in all displays.

Here is a sample I've been working on for a while that shows all the relevant display information from any Android device. I originally wrote it to debug Android Wear displays, but it also supports Android TV, phones, and tablets, using a single APK. You can see everything there is to know about your device (insets, size, resolution, density, etc), understand how big a dp, inch, or cm is really going to be compared to pixels, and use that in your application development. It is available as source code https://github.com/google/wear-screeninfo but it is also approved as a TV app on Google Play as "Wear ScreenInfo" if you want to just test it out.

If anyone has any feature requests for this utility, post them here, and I'd be happy to consider this for a future update.

+Wayne Piekarski Yes, this is what I have. I am in SDK Manager and I saw system images, etc, but no emulators. Which options should I choose for the Android Wear emulators? I am using the latest Android Studio 2.1.3.
