Android Question how to press power button programmatically

toby · Feb 24, 2017

I'm working on an app which will simulate the pressing of the power button from time to time. I'm wondering how.

Thanks in advance for any helps!

Just call the sub... "Your_Button_Click"

@Edgar, sorry, I meant the physical button used to turn on and off your phone.

You cannot press them programatically

Could you describe a little more your need ? Is it to light the screen or really send the Power intent ?

Some Java examples, but i don't know how to implement it:

Set device lock
You can set the maximum period of user inactivity that can occur before the device locks. For example:

DevicePolicyManager mDPM;ComponentName mDeviceAdminSample;...long timeMs =1000L*Long.parseLong(mTimeout.getText().toString());
mDPM.setMaximumTimeToLock(mDeviceAdminSample, timeMs);

You can also programmatically tell the device to lock immediately:
DevicePolicyManager mDPM;
mDPM.lockNow();

You cannot "press" the power button programmatically.

See the Administrator library.

What I really want is to lock my phone when it's alive. Currently I press the power button to achieve that. I want to do this programmatically. Thanks to Erel who's pointed me to the solution. The lock screen feature in The Administrator library and accompanying example does exactly what I need.
