android 分享功能

浏览数：51 / 时间：2015年06月11日

       上一篇讲了android第三方登录，这一篇大概说一下分享。需要注意几点： 

1.登录和分享功能都必须是签名之后的apk，才能用 

2.再吐槽一下，微信SDK做的真他妈的变态，和登录一样，必须是例如我的apk，包名（也就是AndroidManifest.xml中的包名）是com.kingdowin.gosu，你项目中必须有一个包名是com.kingdowin.gosu.wxapi，下面有一个类是WXEntryActivity.java，里面写登录或分享以及获得返回响应结果（public void onResp(BaseResp resp) {}）微信代码，我不得不把自己的MainActivity改为WXEntryActivity。否则就获取不到用户信息，记好是必须。

3.微信分享是文本能分享而图片不能，那是因为你分享的图片太大了，SDK协议中对缩略图的大小作了限制，大小不能超过32K。另外限制的还有title、description等参数的长度。另外Bitmap的compress方法不支持PNG，只支持JPG。

4.qq分享如果包含图片似乎只支持手机里的本地图片而不支持二进制

效果图：

技术分享
