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

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"
