Wearable 4.0: Extra package installation is failed! Sap must be installed Manually!

I am working on companion web API app. My code is working with Wearable emulator 3.0. But when I run it on Wearable emulator 4.0, this error shows up:

Extra package installation is failed! Sap must be installed Manually!

I tried reinstalled Samsung wearable extension in package manager but it doesn’t work. Only 4.0 wearable emulator gets this error.

Please help!
