android 后台自动拍照,怎么实现后台拍照功能,求解

如何实现后台拍照功能,求解。

自己去网上找了一段后台拍照代码，如:

MainActivity.java就实现一个按钮启动一个服务

public void click(View v) {

bindService(new Intent(this, LocalService.class), serviceConnection, Context.BIND_AUTO_CREATE);

}

LocalService.java 服务代码,需要实现拍照功能

package com.mycompay.camhal2serverapp;

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

import android.app.AlarmManager;

import android.app.Service;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.graphics.Bitmap;

import android.graphics.ImageFormat;

import android.hardware.Camera;

import android.Uri;

import android.os.Binder;

import android.os.Environment;

import android.util.Log;

import android.view.SurfaceHolder;

import android.view.SurfaceView;

import android.widget.Toast;

public class LocalService extends Service {

private final static String TAG_LOG="chsmApp";

private final IBinder mBinder = new LocalBinder();
