我正在使用下面的代码在Android中共享图像和文本。当我选择Whatsapp时，它一起共享图像和文本，但是当我选择Facebook时，它只是共享图像而没有任何文本！我的代码中有什么错误？谢谢。
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(bitmapPath)));
share.putExtra(Intent.EXTRA_TEXT, "Shared via" + APP_URL);
startActivity(Intent.createChooser(share, "Share Image"));
Facebook will not allow you to Share any static text you want.
That's why Facebook have provide it's own Share Dialog to post any text on facebook.
It will take image as static but not text.
So better for facebook share only you use Facebook Share Dialog.
The thing is, if you put a URL in the EXTRA_TEXT field, it does work. It's like they're intentionally stripping out any text.
**Check below links for Integration of Facebook Share.**

Android：如何通过意图在Facebook上分享带有文本的图像？
我的代码出了什么问题？
可能什么都没有。 ACTION_SEND在一个Intent中支持EXTRA_TEXT或EXTRA_STREAM，而不是同时支持两者（"...可以有一个EXTRA_TEXT或EXTRA_STREAM字段，其中包含要发送的数据"）。一些ACTION_SEND实现将超出记录的协议，并尝试同时使用两者。其他人会坚持记录在案的协议，只使用一个。在这种情况下，Facebook可能选择坚持记录在案的协议，只使用一个。
Facebook更改了他们的政策，因此您无法同时共享图像和文本。这已经不可能了
你不能再与脸书分享文字了！期间。
使用意图无法在Facebook上共享图像和文本。但是，如果要共享两者，则必须创建图像和文本的位图。
从这里下载源代码（在安卓中使用意图在Facebook上分享图像和文本）
