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:
