Android source code modification, the realization of long press the power button directly shut down the machine

Version: Android 4.4.2

Source file path: Frameworks\base\policy\src\com\android\internal\policy\impl\phonewindowmanager.java

Modify the following code:

Private final Runnable mpowerlongpress = new Runnable () {@Override public void run () {//the CO ntext isn ' t read if (Mlongpressonpowerbehavior < 0) {Mlongpressonpowerbehavior = mcontext.ge            Tresources (). Getinteger (Com.android.internal.r.integer.config_longpressonpowerbehavior);            } int resolvedbehavior = Mlongpressonpowerbehavior;            if (factorytest.islongpressonpoweroffenabled ()) {resolvedbehavior = long_press_power_shut_off_no_confirm;            }/* switch (resolvedbehavior) {case long_press_power_nothing:break;                Case long_press_power_global_actions:mpowerkeyhandled = true; if (!PERFORMHAPTICFEEDBACKLW (null, hapticfeedbackconstants.long_press, False)) {Performauditoryfeedbac                Kforaccessibilityifneed (); } sendclosesystemwindows (System_diaLog_reason_global_actions);                Showglobalactionsdialog ();            Break Case Long_press_power_shut_off:case long_press_power_shut_off_no_confirm:mpowerkeyhandled = tr                Ue                PERFORMHAPTICFEEDBACKLW (null, hapticfeedbackconstants.long_press, FALSE);                Sendclosesystemwindows (system_dialog_reason_global_actions);                Mwindowmanagerfuncs.shutdown (Resolvedbehavior = = Long_press_power_shut_off);            Break            }*///Comment out the above code, add the following code mpowerkeyhandled = true;            PERFORMHAPTICFEEDBACKLW (null, hapticfeedbackconstants.long_press, FALSE);            Sendclosesystemwindows (system_dialog_reason_global_actions); Mwindowmanagerfuncs.shutdown (false);//Here false means do not display the Shutdown prompt box, true does not display the Shutdown prompt box}};

When modified, long press the shut down key will shut down directly.
