Open the file:\ frameworks\ base\ policy\ src\ com\ android\ internal\ policy\ impl\ PhoneWindowManager.java
In the code:
private static final int MSG_POWER_LONG_PRESS = 14;
Add the following:
private static final int MSG_POWER_SHUT_DOWN=15;
At:
case MSG_POWER_LONG_PRESS:
powerLongPress();
break;
Add the following:
case MSG_POWER_SHUT_DOWN:
mWindowManagerFuncs.shutdown(false);
break;
Find
case KeyEvent.KEYCODE_POWER:
Comment out
/*result &= ~ACTION_PASS_TO_USER;
isWakeKey = false; // wake-up will be handled separately
if (down) {
interceptPowerKeyDown(event, interactive);
} else {
interceptPowerKeyUp(event, interactive, canceled);
}
break;*/
Add:
if(down){
if(mPowerManager.isScreenOn()) {
Message msg = mHandler.obtainMessage(MSG_POWER_SHUT_DOWN);
msg.setAsynchronous(true);
mHandler.sendMessageDelayed(msg,
ViewConfiguration.get(mContext).getDeviceGlobalActionKeyTimeout());
} else {
Log.e("GO to Wakeup--------> TTTEEE","keyCode :"+keyCode);
wakeUpFromPowerKey(event.getDownTime());
}
}
break;
Then android is compiled in the directory frameworks/base/policy. policy. jar push is restarted from system/framework
