Can't run native project on Galaxy Gear 2 ??

I just create and build a native project using Tizen SDK instead of SDK for Wearable since SDK for Wearable would not let me create a native Tizen project. However I can not launch the native App on Galaxy Gear 2 with the error message like this:

Cannot install application.

Error code: FATAL_ERROR

Error message: 

Command: /usr/bin/pkgcmd -q -i -t tpk -p /opt/usr/apps/tmp/Mf7csltynQ-1.0.0-arm.tpk

Management: Installation or uninstallation is not working temporarily.

So I searched for solutions on the internet. Unfortunately, all the people are saying Samsung doesn't support native project for Gear 2.

Really don't understand why they release such a SDK only support Web project!!
