I am using Tizen SDK (2.4.0_Rev5) to launch the demo app HelloTizen (wearable-2.3) on my Gear S2 but it fails, with the following error:
Unknown Error [81]
Unknown Error [81]
When I try to install it with sdb install HelloTizen.wgt I get the following output:

1 file(s) pushed. 0 file(s) skipped.

There is the output from sdb dlog:

So, it seems to be a certificate related error. I did generate my certificate in Security Profiles with one generate author certificate and the automatic certificate for distributor. I also used Register Certificate but I do not know if it worked because when I clicked on OK, nothing happened.
The other thing I did was to enable Permit to install applications for my device. But, as for the certificate registration, I do not know if it worked because nothing happened. I checked in /home/developer and there is no device-profile.xml file.
回答1:
If you run app in Emulator, then IDE generated certificate will work. But you are running app in Gear S2 which has user binary, that's why you need to get author certificate from samsung. Below link will show you the way of installing extension sdk for certificate for both emulator and device.
