Android：共享意图不适用于视频文件路径

Question

我有一个视频文件路径，想在社交媒体上共享视频，但是无法共享视频。我正在尝试遵循Android Studio 2.2中的代码，但是无法正常工作。

程式码片段：

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button shareBtn = (Button) findViewById(R.id.sharebutton);

    shareBtn .setOnClickListener(
            new Button.OnClickListener() {
                public void onClick(View v) {

                    File f = new File("/sdcard/VID_20161201123613.mp4");
                    Uri uriPath = Uri.parse(f.getPath());

                    Intent shareIntent = new Intent();
                    shareIntent.setAction(Intent.ACTION_SEND);
                    shareIntent.putExtra(Intent.EXTRA_TEXT, "Text");                  
                    shareIntent.putExtra(Intent.EXTRA_STREAM, uriPath);
                    shareIntent.setType("video/*");
                    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    startActivity(Intent.createChooser(shareIntent, "send"));

                }
            }
    );
}

尝试这个 ：

public void shareVideo(final String title, String path) {

MediaScannerConnection.scanFile(getActivity(), new String[] { path },

            null, new MediaScannerConnection.OnScanCompletedListener() {
                public void onScanCompleted(String path, Uri uri) {
                    Intent shareIntent = new Intent(
                            android.content.Intent.ACTION_SEND);
                    shareIntent.setType("video/*");
                    shareIntent.putExtra(
                            android.content.Intent.EXTRA_SUBJECT, title);
                    shareIntent.putExtra(
                            android.content.Intent.EXTRA_TITLE, title);
                    shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
                    shareIntent
                            .addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
                    context.startActivity(Intent.createChooser(shareIntent,
                            getString(R.string.str_share_this_video)));

                }
            });
}
