Force an android phone to sleep, in order to test?

I'm writing an android application that depends on netw开发者_C百科ork activity and the alarm manager sometimes waking the phone up from a sleeping state.

My question is how can I reliably test this on device? Ideally, how can I force the phone into a full-on sleeping state. Failing that, how can I know for sure when the phone has fully gone to sleep?

How do you test your Alarm Manager / Wake Lock / Sleep handling code?

Turn off the screen of the device/emulator and then run the following commands:

adb shell dumpsys battery unplug
adb shell dumpsys deviceidle step

Re-run the second one until you get the message "IDLE". This works on devices running Android 6.0 or newer.

Step 1

a. Put the device to "discharging" in settings (follow instructions in the red boxes).

b. Turn off the device screen by pressing the "power" button (blue box).

Step 2

a. To directly put the device to sleep mode, run:

adb shell dumpsys deviceidle force-idle

b. Or slowly step into sleep mode, run:

adb shell dumpsys deviceidle step multiple times.

Step 3

To confirm device idle status, run:

adb shell dumpsys deviceidle get deep

Pressing the power button on the device should put it to sleep. There is also a goToSleep(long time) method in the PowerManager, but that requires DEVICE_POWER permission, which is reserved for system applications.

if u want to test on the emulator then from home screen press menu -> setting -> applications -> development ->uncheck stay awake
