How to upload video to youtube in android?

Question

I am Creating an application which records video and uploads it on YouTube and others Social sites.

For upload I use Droid share functionality and it works good.

In e-mail, Facebook, Skype, etc upload works perfect, but when I select YouTube, it does not upload my video.

Here is the code I use for video sharing.

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"SUBJECT_NAME");
sharingIntent.setType("video/*");
File newFile = new File(video_path);
sharingIntent.putExtra(android.content.Intent.EXTRA_STREAM,Uri.fromFile(newFile));
startActivity(Intent.createChooser(sharingIntent,"Where you want to share?"));
