Hello,
I believe that running the following adb command powers down an Android device via USB, but turning it on, hmm, goof luck with that.

B4X:

adb shell reboot -p

Enjoy...

i don´t think it is possible. I did not see any SDK for this.

Turning it off should be possible by using the adb command @Peter Simpson suggested in his post. It could probably be done, without USB connection, also by using Accessibility Services.

Turning it on is probably very difficult unless there are some pre-installed binaries on the phone. Found this (not tested by me though):

Source:
If you enabled USB debugging and installed Minimal ADB & Fastboot before the phone turned off, go to your computer and launch the tool. Plug in your phone via USB, then type adb reboot and hit enter. Also try adb reboot recovery. This will not work for all phones when they are switched off, but it is worth a try.
