问题
I'm trying to develop an android wearable application but I don't have wearable device. So I'm using an Android wearable emulator. I tried to connect with wearable emulator and phone. Phone connected with usb cable. My phone API version is 19. Wearable emulator version 20. I installed Android Wear application in my phone. I tried to connect emulator and device by ADB command. I'm not sure bluetooth need to open in mobile device because i think usb cable can connect to wearable emulator.
Check The Device List
adb devices
Results
C:\Program Files (x86)\Android\android-studio\sdk\platform-tools>adb devices
List of devices attached
HT365W906209 device
emulator-5554 device
AVD communication port to phone
adb -d forward tcp:5601 tcp:5601
Results
C:\Program Files (x86)\Android\android-studio\sdk\platform-tools>adb -d forward tcp:5601 tcp:5601 C:\Program Files (x86)\Android\android-studio\sdk\platform-tools>
After executing the above command, I can't connect with my device and emulator. I followed this tutorial.
This is android wear application in my phone.
回答1:
You, and the tutorial as well, haven't mentioned that you explicity selected Pair with emulator right inside the Android Wear Companion app.
So please give this a try:
Step 1 - Select "Pair with a new wearable"
Step 2 - Select "Pair with emulator"
Afterwards the ActionBar should say "Emulator - Connecting...". Execute the adb forward comand once again and it should work.
