Intent for editing plain text file with the instal

问题:

I want my app to open a plain text file with any of the file editors installed on my terminal, but I keep getting this exception:

ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.EDIT dat=file:///sdcard/folder/file.txt } 

First I thought that I have no File editor installed, but if I use ASTRO file manager, I can get to open the file both with "File Editor" and "QuickOffice", so I think the problem is that I'm not using the right code...

Here is the code

Intent intent = new Intent(Intent.ACTION_EDIT); 
Uri uri = Uri.parse("file:///sdcard/folder/file.txt"); 
intent.setDataAndType(uri, "plain/text"); 
startActivity(intent);

What is more surprising is that if I use the path of a file that doesn't exist, it keeps raising the same exception...

Thanks

The MIME type is text/plain.
