Question

我在我的Android应用程序中包含了Twitter Fabric SDK，可以发布推文。我也希望发布图片，但通过用于发布纯文本推文的StatusesService似乎无法实现。

是不是可以通过SDK完成此操作？我是否必须为此做一个明确的http帖子？

Answer 1

根据Fabric SDK，是的，您可以通过TweetUI在您的推文中嵌入媒体。

示例代码

使用Fabric初始化

str

推文代码

Fabric.with(this, new TweetComposer());

<强>记住

如果未安装Twitter应用程序，TweetComposer将会创建在浏览器中与Twitter.com交互的意图。该浏览器忽略指定的图像。
