Android上的蓝牙文件传输

Question

I have been trying to write a program for transferring a file which the user selects from a ListView that i provide to the user. Once the user selects a file which he intends to transfer ( "I achieved that using onLongClickListener " ), this particular block of code is triggered:

    String mimeType = fileAction.getMimeType(rowHolder.get(position).getLabel());
            Intent playFile = new Intent();
            playFile.setAction(android.content.Intent.ACTION_SEND);
            Uri pathUri = Uri.parse("file://" + currentPath +     rowHolder.get(position).getLabel());
        playFile.setDataAndType(pathUri, mimeType);
        startActivity(playFile);

The trouble is that when I select the Bluetooth option from the list of options of applications which can handle this type of Intent [" This part is automatic "] nothing happens. This problem is only occurring when I am clicking on Bluetooth. All the other options like GMail, Bump, etc are working perfectly. Any help/Guidance would be appreciated. Thanks in Advance. Also, this is my Manifest File in case it seems that the sets of permissions is less than required. AndroidManifest File:

Try this code::Refer this LINK

String mimeType = fileAction.getMimeType(rowHolder.get(position).getLabel());
Intent intent = new Intent();  
intent.setAction(android.content.Intent.ACTION_SEND);  
intent.setType(mimeType);
Uri pathUri = Uri.parse("file://" + currentPath + rowHolder.get(position).getLabel());
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pathUri ) );  
startActivity(intent);

Updated::

File file = new File(Path.toString());  
intent.setDataAndType(Uri.fromFile(file), mimeType);
