Try by replacing this code 

 HashMap hm = new HashMap(); 
            hm.put("Chennai","123");

with 

HashMap<String, String> hm = new HashMap<String, String>(); 
            hm.put("Chennai","123");

sp.setOnItemSelectedListener(new OnItemSelectedListener() {

            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                int item = sp.getSelectedItemPosition();
                Toast.makeText(getBaseContext(), 
                        "You have selected the book: " + androidBooks[item], 
                        Toast.LENGTH_SHORT).show();
            }

            public void onNothingSelected(AdapterView<?> arg0) {
            }
            
        });

in toast you get selected item pass this item to another screen.
