问题 I'm sending a notification from an android handheld device to an android wear device. I'd like to include an action with the notification that starts an activity on the android wear device. How do I set the pending intent to an activity on the wear device?

Also assume that bitmap has been initialized to an appropriately-sized image (though that's another issue). Method 1: bob.setLargeIcon(bitmap); This works, but AFAICT bitmap is always blurred-out in the background of

问题 Just to be sure and have clarification of that at first, is the NFC of the Smartwatch 3 just an embedded tag or is it a theoretically fully functioning NFC-chip? Hoping it's not just a tag, we want to build an Android Wear app using NFC and for this the biggest question is: Is there (gonna be?) a API to use the NFC chip of the SWR50? If not is there any other way to activate it, or maybe might an updated version of Android Wear bring support for the chip to the smartwatch? Any help is

问题 I have been trying to push data to the android wear emulator. But all in vain. My listener on the emulator is not receiving any calls whatsoever. If anyone else has tried working on wear and pushing data to wear please HELP. This is what my receiver code looks like private GoogleApiClient mGoogleApiClient; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_qrcode_generation); mGoogleApiClient = new

You can do this by passing own custom Activity by setDisplayIntent() , code sample: public Notification buildNotification(Context context) { Intent displayIntent = new Intent(context, AnimatedNotificationDisplayActivity.class); displayIntent.putExtra

问题 I have an app which uses the AlarmManager to regularly wake up the phone at full hour and send a message to an Android Wear watch which than makes a short vibration. I have two users with a Samsung Galaxy S6 with stock Android 5.1.1 and the Sony SW 3 with 5.1.1 who experience a weird bug. At the very first full hour the vibration is at the exact time but all other vibrations are 3 minutes delayed. Sometimes even the first full hour vibration is delayed. Here is some code: final Calendar time
