Need help debugging error when trying to access data in android sqlite database

I am trying to access the information stored in my database by using the id that I am passing in from a list.

Here is the code i have on my mainList class:

studentList.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
            int position, long id) {
            try {
                String selected =parent.getItemAtPosition(position).toString();
                Log.d("position: ", selected);
                Class page = Class.forName("com.example.ltss.dyslexia.app.StudentProfilePage");
                //Intent intent = new Intent(getApplicationContext(), StudentProfilePage.class);

                Intent intent = new Intent(MainList.this, StudentProfilePage.class);
                //Intent intent  = new Intent(MainList.this, page);
                intent.putExtra("id", selected);

                String size = String.valueOf(id);
                Log.d("id is: ", size);
                intent.putExtra(ID_EXTRA, String.valueOf(id));
                startActivity(intent);


            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }
           /*Toast.makeText(getApplicationContext(),
            ((TextView) v).getText(), Toast.LENGTH_SHORT).show();*/
        }
    });

and my studentProfilePage (where i'm passing the data):

public class StudentProfilePage extends Activity {
String passedVar = null;
private TextView id = null;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.student_profile_page);
    passedVar = getIntent().getStringExtra(MainList.ID_EXTRA);
    //id = (TextView)findViewById(R.id.id);
    final DatabaseHandler dyslexiaDb = new DatabaseHandler(this);
    //dyslexiaDb.openDatabase();
    String data[] = dyslexiaDb.retrieveDataFromStudents(passedVar);

Here is what I have in my DatabaseHandler class:

public String[] retrieveDataFromStudents(String id){
       String table_name = TABLE_STUDENTS;
       // Create query
       String selectQuery = "SELECT * FROM "+table_name+" WHERE studentId = "+id;
       dyslexiaDatabase = this.getReadableDatabase();
       // set up Studnet Cursor (sCursor)
       Cursor sCursor = dyslexiaDatabase.rawQuery(selectQuery, null);
       String [] data = null;
       int count = 0;
       String[] data2 = data;
    if(sCursor.moveToFirst()){
           do{
               data2[count] = sCursor.getString(count);     
               Log.d("info", data[count]);
           }while(sCursor.moveToNext());
       }
        dyslexiaDatabase.close();
       return data2;
   }

And here is the error I'm getting:

I am currently using an Adapter instead of a CursorAdapter (just until I get the CursorAdapter working correctly) I just need to get one page displaying user data using the ID that's passed through as soon as i can.

Am I doing something seriously wrong?

Thanks for any help you can give me!
