Hello,
I do monitor already the battery with some crontab job. I would like to
make a signal to the device owner (my wife) when the problem of fast
battery drain occurs, i.e. when for example the drainage in a given
interval is unusual high; I figured already out how to play a sound with:
$ sudo cp /var/lib/lxc/android/rootfs/system/res/sound/ringtone.wav ~
$ sudo chown phablet ringtone.wav
$ ubuntu-app-launch mediaplayer-app file:///home/phablet/ringtone.wav
This gives a 10 second continuous beep (not really a ringtone as the
filename says, but very good for the purpose);
How can I pop-up in parallel a message box on the screen with some text
like "Battery drain! Re-boot NOW and re-charge!", if possible together
with an OK button which fires up "sudo reboot"?
Thanks
matthias
