cannot reboot Android from terminal

Question

I need to restart my app often to test the behavior of some components. So I want to use a cmd from terminal in order to not waste time closing / opening manually. I have found this code but when I put on the terminal it returns a permission error.

CMD to reboot from terminal:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

Terminal Response:

java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.BOOT_COMPLETED from pid=13940, uid=2000

anyway the reboot of system should not be affected by app manifest — Giorgio Cafiso, Mar 11 '19 at 13:08
That's why you can't run adb in root mode as advised in the thread linked earlier. Try with an emulator, one that does not use the Google Play Services if I recall correctly — Ephi, Mar 11 '19 at 13:29
Check [this](https://stackoverflow.com/questions/43923996/adb-root-is-not-working-on-emulator). Alternatively, if it's only for the sake of testing, can you try using another intent to fake a reboot ? — Ephi, Mar 11 '19 at 13:36
`android.intent.action.BOOT_COMPLETED` is not for rebooting, it's an intent sent by the system when the device has completed booting. You cannot send it because it is a system action; you need root to send it. — m0skit0, Mar 11 '19 at 14:13

That broadcast won't work as it is a system privileged Intent. If you just need to restart your app clean in a certain activity, the am command has an option to force stop the running process (-S) before delivering the Intent:

adb shell am -S -a "android.action.MAIN" -c "android.category.DEFAULT" -n "your.package.name/.YourActivityName"

i don need to restart the app. I need to fire the event of the reboot of the sistem, without closing/opening manuall operations. – Giorgio Cafiso Mar 12 '19 at 13:08
OK, that was not clear from your question. You cannot directly simulate boot complete by sending that `Intent`. The system only allows it to be sent by the internal Android framework. – Larry Schiefer Mar 12 '19 at 16:58
