Hi i am creating an alarm app and currently have some issues dealing with the Wakelock(or perhaps it's something else) and make the alarms work when the phone is asleep, however my question isn't actually about the Wakelock, but rather about how to make the phone go to sleep so I can test the various options I want to implement on my alarm app. Currently I have to wait for the phone to go to sleep before I can test my code. So is there a way to put the phone in deep sleep programmaticaly?

I ran into the same question during my dev work. The android docs are not very useful -- use adb to switch into doze mode (deep sleep):

adb shell dumpsys deviceidle force-idle

and equally useful, use:

adb shell dumpsys deviceidle step

or

adb shell dumpsys deviceidle unforce

to get back to "normal" mode. Brief intro:

adb shell dumpsys -l  #(lower case "L") list subsystems (deviceidle is one)

then:

adb shell dumpsys deviceidle -h  #parameters with brief description

Also, adb needs access to your device (or emulator) to get this information. Good luck!
