Processing don't see phone

Installed Processing Android library and try to run some program in my mobile phone, but when I shifting from Java mode to Android, stk not fond message appears. I tried automatically installing, but then it doesn’t see my device, I can’t run simple code on phone. I tried to install sdk path manually and even downloaded android studio but it doesn’t find sdk directory anyways.
