Hello, i’m developing a Samsung app but i can’t run it into the emulator. This is the error i received:

“step SDB shell handle failed
Failed to `step SDB shell handle ‘2 mkdir /tmp UserX’ command` operation
 (Return Code:31)sdb command rejected exception”

Thank you!

*i’ve checked the sdb’s capability
