Wear am I?

Initial foray into Android wear development

[hellomikedg]

Pretty awesome that the sync API auto syncs once the wear app gets installed. So no need to wait for the wear app to install before trying to sync.

Watch faces are possible with no API

Deploying a Wear app to the play store?

When packahging your Wear app inside another APK, make sure to 

Turn off Asset Compression

Many build tools automatically compress any files added to the assets/ directory of an Android app. Because the wearable APK is already zipped, these tools re-compress the wearable APK and the wearable app installer can no longer read the wearable app.

When this happens, the installation fails. On the handheld app, the PackageUpdateService logs the following error: "this file cannot be opened as a file descriptor; it is probably compressed."

To prevent this error in Android Studio, update your handheld app's build.gradle file with the following declaration:

android {   aaptOptions {     noCompress "apk"   } }

Looks like the ambient watch faces are Dreams.

So much too short

I’ve been seeing about 12 hour battery life. Battery life is too short.

I can’t leave my phone in the living room and go up stairs without losing connectivity. BT range is too short.

You are now a developer!

How do we enable developer mode on Android Wear devices? It's pretty much identical to how we do it on phones.

Say "Ok Google, Settings" to get to the settings screen. 

Scroll to the About option and select it.

Scroll to Build number, then tap on it about a dozen times and it will show a Toast saying that "You are now a developer"

Back out of this screen and you should see "Developer options" below "About"

Bluetooth debugging is awful

It seems really slow to deploy, which is making it near useless.

Setting up a G-Watch on windows

As usual new devices are a pain in the ass to use via ADB on Windows. OSx and Linux have it easy.

Turn off driver signature enforcement.

Go into the USB driver extras directory on your Android SDK. Something like C:\Users\Michael\AppData\Local\Android\android-studio\sdk\extras\google\usb_driver

Copy that entire folder somewhere safe.

Open android_winusb.inf in a text editor

Toss the next two lines under [Google.NTx86] and [Google.NTamd64] ;Wear GWatch %SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_D002 %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_D002&MI_01

The above lines basically say to use this driver for your GWatch.

Now go into device manager, you should see a GWatch with a yellow sign next to it complaining about the drivers. 

Double click that and select update driver.

Point if to the directory you just copied and modified.

It should complain about the driver signature being incorrect, that's fine though.

Once that's installed, your device should be usable via ADB
