public class MainActivity extends Activity {
 private Button btnstarted = null;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
     btnstarted = (Button)findViewById( R.id.btnstarted);
     btnstarted.setOnClickListener(new OnClickListener() {
   public void onClick(View v) {
    Intent intent = new Intent(MainActivity.this,StartService.class);
    startService(intent);
    Toast.makeText(MainActivity.this, "服务启动成功", Toast.LENGTH_LONG).show();
   }};}
}

public class BootCompletedReceiver extends BroadcastReceiver{
 public void onReceive(Context context, Intent intent) {
  if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
   Intent newIntent = new Intent(context,StartService.class);
   context.startService(newIntent);
  }
 }
}

public class StartService extends Service{
 //public static String PHONENO;
