I have a problem. I Worked with one table in my database and I had no problem... Well now I add another table and problems started..

I have a problem. I Worked with one table in my database and I had no problem...

Well now I add another table and problems started..

In my principal activity, I open the database (writable mode) to fill information stored in an array.. then I close it, after that I reopen it (readable mode) and I fill a table with data stored in my database... then I close DB. that was working in all the activities I was doing that..

Well now I have another activity that just do the same with another table, open it as writable to fill it, close.. and then open it as readable and fill a table and close..

And after I do this, I have the LogCat that says SQLite created and never closed.. what? I did the same thing as always.. here is part of my activity which is getting me into trouble:

     UsuariosSQLiteHelper usdbh =
                new UsuariosSQLiteHelper(this, "DBIncidentes", null, 1);

            SQLiteDatabase db = usdbh.getWritableDatabase();         //Abro base de datos para escritura

            if(db != null)
            {

                 db.execSQL("DELETE from Moviles");
                 for (int i=0; i<= (vecTotal.length) -1; i++) {



                String reg = vecTotal[i].toString(); 
                String [] inc = TextUtils.split(reg, "\\^");




                String numMovil = inc[0];
                String colMovil = inc[1];
                String estado = inc[2];
                String localidad = inc[3];
                String strCantServ = inc[4];

                Integer cantServ = Integer.parseInt(strCantServ);



                try{                

                    //Insertamos los datos en la tabla Incidentes
 db.execSQL("INSERT INTO Moviles ( idInterno, numMovil, colMovil, estado, localidad, cantServ) " +
             "VALUES ("+(i+1)+", '" + numMovil +"', '" + colMovil +"' , '" + estado +"', '" + localidad +"', " +cantServ +" )");



}

catch (Exception e)

{
    e.getMessage();


}

    }


    catch (Exception e)

    {


        e.getMessage();
    }





}

I use the same helper for the two tables, and my new table is full of data.. but it isn't displayed in my screen and i have the error of created and never closed..


In UsuariosSQLiteHelper class, did you really implement method close()?


try to implement the overridden method close() for database, and after every operation call close(), will cloase ur database...

@Override
public synchronized void close() {

    if (myDataBase != null)
        myDataBase.close();

    super.close();

}

Hope u get my point...
