Open any type of file of Android without declaring MIME type explicitly

I am using this method to open launch an Intent to open a file on Android (I've described my problems in the comments):

public static void openFile(Context context, String fileName) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        // intent.setType(FileHelper.getMimeType(file)); // this doesn't work for PDF files
        // opens Intent but then the chosen application doesn't open the file
        intent.setType("application/pdf");  // this works correctly for PDF files
        intent.setData(Uri.parse("file://" + getPath(context) + fileName));
        context.startActivity(intent);
    }

I would like to have a single method that would open any kind of file, without having to explicitly specify the MIME type, is that possible?

Mime type is needed to open the file i.e. we have to set Data and Type. You can use this function to open any file:

public void openFile(Context ctx,String filepath)   
{   
Uri ttt = Uri.parse("file://" + filepath);
Intent intent = new Intent(Intent.ACTION_VIEW);
String arr[] = filepath.split("\\.");
MimeTypeMap myMime = MimeTypeMap.getSingleton();
String mimeType = myMime.getMimeTypeFromExtension(arr[arr.length - 1]);
intent.setDataAndType(ttt, mimeType);
ctx.startActivity(intent);
}

However, there will be problem in files without extension.
