Answer 2

So which apk should I install on my smartphone, which would sync the corresponding setup to the Android Wear?

That's true only when the apk is exported and signed with the production certificate. When you develop, you have to explicitly install the apk, on both devices. You just need to switch between the wearable and handheld application on AndroidStudio, in the drop down menu next to the run button, and choose the device, in the popup which prompt the attached devices

Easiest way to install wearable apk :

1. Make sure your package name of wearable and mobile are same.Go to AndroidManifest .xml file both these module and check whether these are same or not. If same then ok otherwise you have make them same.

2. Normally, There two apk's are available in wearable project one is "Mobile APK" and another is "Wearable APK".
