Correct your query with below: add space at WHERE Cause

String selectQuery = "SELECT lastchapter FROM Bookdetails WHERE bookpath=? ";

Update: go with rawQuery() becoz it's return Cursor with results

 String selectQuery = "SELECT lastchapter FROM Bookdetails WHERE bookpath=? ";
 Cursor c = db.rawQuery(selectQuery, new String[] { fileName });
 if (c.moveToFirst()) {
 temp_address = c.getString(0);
 }
  c.close();

The logcat said it all, you've forgot spaces. To get data into the string:

String temp_address="nothing";
String[] args = new String[] { fileName };
Cursor cursor = sqLiteDatabase.rawQuery("SELECT lastchapter FROM Bookdetails WHERE bookpath=?", args);
if (cursor.moveToFirst()){
    temp_address = cursor.getString(cursor.getColumnIndex("lastchapter"));
}
cursor.close();

There are SQL syntax problems and you'll need to use a Cursor to retrieve query results, for example with rawQuery():

String selectQuery = "SELECT lastchapter FROM Bookdetails WHERE bookpath=?";
Cursor c = db.rawQuery(selectQuery, new String[] { fileName });
if (c.moveToFirst()) {
    temp_address = c.getString(c.getColumnIndex("lastchapter"));
}
c.close();
