阅读更多关于 How to detect if android device is paired with android wear watch

I am creating an android wear app that extends push notifications. My app downloads approximately 10 images from a server when a push notification comes in and displays these additional images on the watch. These images are specific to the android wear app and are not shown on the handheld device. How do I tell if the handheld device is paired with an android wear device so that I can determine if it is necessary to download the additional images required for the wear app? Thanks! You need to use the NodeApi , in particular NodeApi.getConnectedNodes() . For example (from a background thread --

WearableListenerService, onDataChanged() is not called

阅读更多关于 WearableListenerService, onDataChanged() is not called

问题 I followed the tutorial to invoke a Wearable activity from phone, posted here How to send notification from handheld to wear to open Activity on wear device. However, I grab the source code from the answer. However, I couldn't get it running. It looks like onDataChanged() is never called. I ask this as a question on its own because it seems the example works for others. I'm on KitKat 4.4.2, if that matters. Any tip where to check, thanks. 回答1: There are two things you can check: packageName

问题 I have a smartphone app with a wear app that has been packaged inside of it, similar to the first two steps of this section: https://developer.android.com/training/wearables/apps/packaging.html#Studio I was originally told that my smartphone wasn't running an SDK large enough to support the app (my phone was using KitKat, apparently I needed API 20), so now I am using my Nexus 7 with Android L preview, and this problem has appeared: I have a smartwatch emulator and tablet running, and both

Android Wear Watchface Settings on host

阅读更多关于 Android Wear Watchface Settings on host

问题 I currently have an android wear watchface developed. I however would now like to create a settings section on the host app that would allow the user to customize the watchface. I am new to the android development so I am curious on the correct way to do this. Is there a way to update a sharedpreference on the host and then push or sync that with the sharedpreference on the wear device? Or is there a totally different way I should be looking at this? 回答1: You can use the DataApi or MessageApi

I found another similar problem on SO (link) which had a sort-of solution, but now it says "Error: The java Plugin has been applied, but it is not compatible with the Android Plugins" This is my build.gradle in my

问题 I want to make bidirectional data transfer between Android Wear and Handheld. All seems to be good except triggering onDataChanged on Handheld. It triggers only then I plug in\out USB cable, connected to the PC. So I don't understand why it's happen.
