android - Get database path

Im new to android and I want to create kind of CRUD with SQLite.

I have a public class DataBaseHelper which have a constructor:

public DataBaseHelper(Context context)
{
    this.context = context;
}

and a getter for datebase:

public SQLiteDatabase getDataBase() {
    if (dataBase == null) {
        try {
            dataBase = context.openOrCreateDatabase(DataBaseHelper.dbName,
                                                    Context.MODE_PRIVATE, null);

            dataBase.execSQL("CREATE TABLE " + DataBaseHelper.accountTblName + " " +
                                        "(ID integer PRIMARY KEY AUTOINCREMENT" +
                                        ",name TEXT" +
                                        ",address TEXT" +
                                        ",password TEXT)");
            }
            catch(Exception e) {
                Log.e(context.toString(), e.getMessage());

                if (dataBase != null) {
                    dataBase.close();
                }
            }
    }       
    return dataBase;
}

If I start a program for the first time - everything seems to be okay. database is null and I create it (with a table). But when I restart my app database is null again and table cannot be created.

I've decided to write a checkDB function, which tries to open a database. But where can I get a path for it? I dont want it to be "hardcoded".

Or may be I'm doing some kind of anti-pattern?

You can get path by context.getDatabasePath(DataBaseHelper.dbName)
