            ("_data", fileName); 
            (.PICASA_ID, fileName); 
            (.DISPLAY_NAME, fileName); 
            (, fileName);

//where app_id is the application ID, find the ID          
//by clicking on your application on Market home          
//page, and notice the ID from the address bar      

I just found the app id but failed, but I found that using package name is also OK.

This is much simpler

           ("/phone"); 
           startActivityForResult(i, REQUEST_TEXT); 

            <2>
