Ok guys, here go some explanations:

The file DB was added to folder assets.
As you may imagine, DB is the database of our app. It is not complete yet, has some data about buildings, rooms and coordinates, and some tables only.
 To chage database, I suggest: copy the DB file to your computer, open it with a SQLite manager (I suggest SQLite Expert Personal), make the changes, and replace it.

 to MainAcitivity.java, the following lines were added:
         try {
             String destPath = "/data/data/" + getPackageName()
                     + "/databases/DB";

             File f = new File(destPath);
             if (!f.exists() || overwrite_database) {
                 CopyDB(getBaseContext().getAssets().open("DB"),
                         new FileOutputStream(destPath));
             }
         } catch (FileNotFoundException e) {
             e.printStackTrace();
         } catch (IOException e) {
             e.printStackTrace();
         }

 when replacing the database file, set overwrite_database = true and it will be replaced by the application. It will copy the database to the folder android uses to query the db.

   The classes in adapters package are our "Inteface" to the database. Add your on query methods there. To query the database in an activity, add a line such as
   DBAdapter db = new DBAdapter(this); //Or directly one of the SBAdapter children
   and use the db object methods.

   Well, I don't know if it is the best way to do things, change them the way you think is better.
