乐橙平台大华监控Android端实时预览播放

一、初始化

首先我们需要到乐橙开放平台下载android对应的开发包，将sdk中提供的jar和so文件添加到项目中；

二、获取监控列表

监控列表我们是通过从自家后台服务器中获取的，这个自己根据需要调整；

三、实时预览

添加预览工具类：

package com.aldx.hccraftsman.utils;

import android.content.Context;
import android.os.Handler;
import android.os.Message;
import android.view.ViewGroup;

import com.aldx.hccraftsman.model.LeChangeRecordInfo;

    private static final String TAG = "LeChange";
    private Handler handler;
    public LCOpenSDK_PlayWindow lcOpenSDK_playWindow;  //播放窗口

    public PlayerLeChange(Context context, ViewGroup viewGroup, Handler handler) {
        LCOpenSDK_Api.setHost("openapi.lechange.cn:443");  //设置乐橙服务地址
        lcOpenSDK_playWindow = new LCOpenSDK_PlayWindow();
        lcOpenSDK_playWindow.initPlayWindow(context, viewGroup, 0);  //初始化播放功能，父窗口绑定到LCOpenSDK_playWindow的实例上
        this.handler = handler;
    }
