Android Studio：共享到Facebook Messenger

Question

我正在使用最新的facebook SDK，并且尝试共享设备上的图像。 我已经尝试了所有方法，但现在我不知道该怎么办，但是请您寻求帮助。 这是代码：

        String mimeType = "image/gif";


  Uri contentUri = Uri.parse("/storage/emulated/0/animated.gif");
  // contentUri points to the content being shared to Messenger
        ShareToMessengerParams shareToMessengerParams =
                ShareToMessengerParams.newBuilder(contentUri, mimeType)
                        .build();

// Sharing from an Activity
        MessengerUtils.shareToMessenger(
                this,
                1,
                shareToMessengerParams);

所以这给了我这个错误（来自我的LogCat）：

Answer 1

更新logcat之后，我猜这是重要的几行：

Caused by: java.lang.IllegalArgumentException: Unsupported URI scheme: null
        at com.facebook.messenger.ShareToMessengerParams.<init>(ShareToMessengerParams.java:106)
        at com.facebook.messenger.ShareToMessengerParamsBuilder.build(ShareToMessengerParamsBuilder.java:120)

这是因为您没有提供完全限定的URI。 跟随facebook sdk：

本地内容的uri。 必须是file：//，content：//或res：// URI。
