BaseAdapter中的SQLiteDatabase.openDatabase失败，但是openOrCreateDatabase在Activity中工作正常

Question

I create my database in the onCreate method of an Activity. In this Activity I can add records and I can query records. If there are records that result from my query I add them to a custom ListView, hence the BaseAdapter class. The ListView contains two TextViews and a Delete Button. When the button is clicked I'd like to be able to remove a record from the database, but I cannot seem to open the database. I am trying to open the database like so ...

db = SQLiteDatabase.openDatabase(com.red.myApp.Utils.database_name, null, Context.MODE_PRIVATE);

... this fails with this in the logcat ...

09-19 21:56:15.825: I/Database(4773): sqlite returned: error code = 14, msg = cannot open file at source line 25467
09-19 21:56:15.825: E/Database(4773): sqlite3_open_v2("BookMarksV20.db", &handle, 2, NULL) failed

So what's the deal? Is just plain impossible to use SQLite in type of class other than a Activity or a Service? What am I doing wrong here?

Thank for taking a look :)

I hope this is useful to you.you have to put this code in your create() in activity.

    dbHelper = new DbHelper(this);
    dbHelper.createDataBase();
    sqLiteDatabase = dbHelper.openDataBase();
