Hello all,

I started today with Tizen development (native application) using Tizen studio 1.0.1. I started with the demo project described on tizen.org: Native Application for wearable. I did it twice, once with wearable v2.3.2 and with wearable v2.3.1. Both run proper on the emulator. But when I want to upload them to my S2, both versions failed with error 23, said:

Cannot install application.

Error code: SIGNATURE_VERIFICATION_FAILED
Error message: SIGNATURE_VERIFICATION_FAILED
Command: /usr/bin/pkgcmd -G -q -i -t tpk -p “/opt/usr/apps/tmp/org.example.watch_test2-1.0.0-arm.tpk”
Management: Check whether the package is modified illegally. If there is an installed package which has same name and different signature with your package, you can receive this error return also.

As this is my very first app, there is surely no other app with the same name. Certificate is also setz-up properly, because the emulator works fine. Finally, I literally follow the steps on tizen.org.

Who can give me a good hint how to solve this challenge?

regards and Thanks
