分享截屏总结

这是截屏代码
package com.babeeta.drawview;  

  

import java.io.File;  

import java.io.FileNotFoundException;  

import java.io.FileOutputStream;  

  

import android.app.Activity;

                                        //截图成功

                });  

    }  

}  

sharesdk分享Environment.getExternalStorageDirectory()+ "/" + "1.png" 图片即可，sharesdk分享在微博、微信平台注册时用的是应用签名MD5号+包名。

主意的是

1MD5号要去掉“：”号大写字母小。

2新浪微博账号授权回调页地址和ShareSDK中新浪的RedirectUri="http://sharesdk.cn"要一样。

3还有就是各大平台的appkey、appid、AppSecret要一样。

4当然sharesdk也要注册然后更改appkey

 <ShareSDK 
        AppKey = "fdb41202d656"/> <!-- 修改成你在sharesdk后台注册的应用的appkey"-->
