Android SQLite and huge data sets

Question

We are creating an app for a client that has hundreds of megabytes of HTML in SQLite databases. We have implemented a way to query this data and scroll through it all in a r

If you really need that you can also split your data and read chunks like this:

   int limit = 0;
   while (limit + 100 < numberOfRows) {
       //Compose the statement
       String statement = "SELECT * FROM Table ORDER someField LIMIT '"+ limit+"', 100";
       //Execute the query
       Cursor cursor = myDataBase.rawQuery(statement, null);
       while (cursor.moveToNext()) {
           Product product = new Product();
           product.setAllValuesFromCursor(cursor);
           productsArrayList.add(product);
      }
      cursor.close();
      limit += 100;
 }

 //Compose the statement
 String statement = "SELECT * FROM Table ORDER someField LIMIT '"+  (numberOfRows - limit)+"', 100";
 //Execute the query
 Cursor cursor = myDataBase.rawQuery(statement, null);

 while (cursor.moveToNext()) {
     Product product = new Product();
     product.setAllValuesFromCursor(cursor);
     productsArrayList.add(product);
 }
 cursor.close();

It's working under 2 s for 5k rows if you have indexed table.
