public void loginvalid() throws IOException  {
    String username;
    String password;
    solo.sendKey(Solo.MENU);
    solo.sleep(3000);
    solo.clickLongOnText("Sign In");
    solo.sleep(3000);
    //solo.clearEditText(0);
    username = Readexcel(0,0);
    password = Readexcel(0,1);
    solo.enterText(0,username);
    solo.enterText(1, password);
    solo.clickOnCheckBox(0);
    solo.clickLongOnText("Sign In");

}
public static String Readexcel(int row,int col) throws IOException  { 
    String filename = "C://Documents//Robo//robo1.xls";
    String s = "";

    try
    {
        FileInputStream fis = new FileInputStream(filename);
        HSSFWorkbook myWorkBook = new HSSFWorkbook(fis);
        HSSFSheet mySheet = myWorkBook.getSheetAt(0);
        HSSFRow row1 = mySheet.getRow(row);
        HSSFCell cell1 = row1.getCell(col);
        s = cell1.getRichStringCellValue().getString();
        System.out.println("Cell 1 : "+s);
        Log.d("cell value",s );

        System.out.println(s);
            return s;

    }
    catch (IOException e) {
        e.printStackTrace();strong text
        return null;
    } 

    }
}

Post the stacktrace and tell us which line is throwing that exception. — m0skit0, Jun 19 '12 at 07:54

You are reading the file C://Documents//Robo//robo1.xls, that is stored on your computers HardDrive which your phone of course can't access. You need to put the file on your phone SD-card and use the uri to that location instead:

File storage = Environment.getExternalStorageDirectory() //Returns sd-card
String filename = "robo1.xls"; //file name, may have path separators
File myfile = new File(storage, filename);
//myfile is now a File object that you can use, to get the path, use myfile.getAbsolutePath()
