问题:

I would like to call power off,reboot, etc.. dialog as same as default android dialog when push power button long from my application.
I no need to call directly reboot,power off, etc... from my application.
Just would like to call that dialog.
How to call it ? or How to send power button key on application ?
Thanks in advance.

If you look at the source code, you'll see it's handled internally (PhoneWindowManager.java and GlobalActions.java). There is no interface whatsoever through the API. In short: Can't be done.

If you have the REBOOT permission, you can reboot the phone directly with PowerManager.reboot(), but it is very unlikely that a public app would need this functionality. I wouldn't trust an app with the REBOOT permission.
