本文介绍了一个简单的Android应用程序，用于实现设备的重启和关机操作。通过发送特定的广播Intent，可以触发系统的重启或关机流程。需要注意的是，此类操作通常需要特殊权限，并且仅限系统应用使用。

reboot:



Intent i
=
 
new
 Intent( Intent.ACTION_REBOOT);


intent.putExtra("nowait", 1);

    intent.putExtra("interval", 1);

    intent.putExtra("window", 0);

sendBroadcast( i ); 
shutdown:
Intent i

=
 
new
 Intent( Intent.ACTION_SHUTDOWN);

sendBroadcast( i ); 
public class RebootSystem extends Activity {

    

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        Log.d("U0fly ---======>", "onCreate");

        Button btn = (Button)findViewById(R.id.Button01);

        btn.setOnClickListener(new View.OnClickListener(){

 


            @Override

            public void onClick(View v) {

                // TODO Auto-generated method stub

                Log.d("U0fly ---======>", "onClick");

                rebootAndroid();

            }

            

        });

    }

    

    private void rebootAndroid()

    {

        Intent intent = new Intent(Intent.ACTION_REBOOT);

    intent.putExtra("nowait", 1);

    intent.putExtra("interval", 1);

    intent.putExtra("window", 0);

    sendBroadcast(intent);


    }
