File file = new File(your file);

    try {
        FileInputStream in = new FileInputStream(file);
                    int len = 0;
                    byte[] data1 = new byte[1024];
            while ( -1 != (len = in.read(data1)) ){

                                 if(new String(data1, 0, len).contains(Your String))
                                     //do something...
                     }


    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
