Android Question Wear 2.0 development

Using the new WatchfaceWear2_0 project and Watchface 2.0 library.

Having issues getting the apk installed in debug or release (see below) if I'm using watchface/wear, but I can use ADB to install it manually.

I can't deploy to watch or phone (same errors).

With CustomBuildAction of:
CustomBuildAction: 4, C:\windows\system32\xcopy.exe, WatchfaceWear.apk ..\..\WatchfaceMobile\resource\raw\watchfacewear.apk /Y)

Running custom action. Error
Process timed out.

If I comment out the CustomBuildAction: then it get another error related to privilege (see below):

Installing file to device. Error

BTW, if I compile for debug I get an error:
Running custom action. Error
File not found - WatchfaceWear.apk
Because the compilation creates WatchfaceWear_RAPID_DEBUG.apk vs WatchfaceWear.apk

Thanks
