android 分享功能

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：

微信分享代码：

				前段时间给以前的App加了分享功能,与大家分享一些心得. 实现分享功能有三种方式: 1.调用Android自带的分享接口,这种方式最简单,它是直接调用App的发信息功能,把我们的链接通过信息方式发出去,因此它的分享效果比较差.同时它只能发送给手机上已安装的社交App.最坑的是有些App对此功能是屏蔽的,比如微信朋友圈.代码很简单,网上一搜就有,我就不赘述了. 2.通过第三方SDK来分享,国内比较常用的有友盟和MO.首先要去申请开发,然后下载SDK再调用相应接口就行,缺点是支持部分APP(国内的大
