无法通过 android 4.3 中的 action_send 意图上传视频

Question

我可以通过此代码上传视频，直到 4.1.2 版本的 android。但在 4.3 中失败了。

调用shareVideo()方法android会显示一个应用列表，但是在选择的情况下 youtube 从列表中，youtube 应用程序打开然后停止，没有任何消息，如果选择 instagram，instagram 应用程序崩溃。我也无法通过包括 facebook 在内的任何应用上传视频。

请告诉我是什么问题？？

提前致谢。

public void shareVideo(View view){
    new Handler().post(new Runnable() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            ContentValues content = new ContentValues(4);
            content.put(MediaStore.Video.VideoColumns.DATE_ADDED,
            System.currentTimeMillis() / 1000);
            content.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4");
            content.put(MediaStore.Video.Media.DATA, filename);

            Uri videoURI = getBaseContext().getContentResolver().insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, content);
             //Uri videoURI = Uri.fromFile(new File(filename));
                Intent intent = new Intent(Intent.ACTION_SEND);
                //intent.setAction(Intent.ACTION_SEND);
                intent.setType("video/mp4");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, videoURI);
                try {
                startActivity(Intent.createChooser(intent,"Upload video via:"));
                } catch (android.content.ActivityNotFoundException ex) {

                }
        }
    });

    }

android 4.1 之后改变了sd 卡路径的机制。现在我可以通过视频文件的 id 获取 uri 来上传视频。 这是我的代码

public static String getVideoContentUriFromFilePath(Context ctx, String filePath) {

      ContentResolver contentResolver = ctx.getContentResolver();
      String videoUriStr = null;
         long videoId = -1;
         Log.d("first log","Loading file " + filePath);

         // This returns us content://media/external/videos/media (or something like that)
         // I pass in "external" because that's the MediaStore's name for the external
         // storage on my device (the other possibility is "internal")
         Uri videosUri = MediaStore.Video.Media.getContentUri("external");

         Log.d("second log","videosUri = " + videosUri.toString());

         String[] projection = {MediaStore.Video.VideoColumns._ID};

         // TODO This will break if we have no matching item in the MediaStore.
         Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null);
         cursor.moveToFirst();

         int columnIndex = cursor.getColumnIndex(projection[0]);
         videoId = cursor.getLong(columnIndex);

         Log.d("third log","Video ID is " + videoId);
         cursor.close();
         if (videoId != -1 ) videoUriStr = videosUri.toString() + "/" + videoId;
         return videoUriStr;
     }

点击上传按钮 使用这个方法-

public void shareVideo(View view){
    new Handler().post(new Runnable() {

        @Override
        public void run() {
String newPath=getVideoContentUriFromFilePath(ShareVideoActivity.this, videoPath);
Intent intent = new Intent(Intent.ACTION_SEND);
                     intent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Title");
                //intent.setAction(Intent.ACTION_SEND);
                intent.setType("video/mp4");
                intent.putExtra(Intent.EXTRA_STREAM, Uri.parse(newPath));
                try {
                startActivity(Intent.createChooser(intent,"Upload video via:"));
                } catch (android.content.ActivityNotFoundException ex) {

                }
    }
        }
    });

}
