  • 0

i’m currently trying to get a single row from my own database, located in the assets folder. Checking if there is a row in the table, with the SQLite Query Browser and the SELECT-Statement from the debugger got me a single row in the database. Anyway calling the statement from my code just gets me an empty cursor. I also added the method

cursor.moveToFirst()

and avoided calling

myDataBase.close();

Here is the method where i’m trying to append a single entry on a TextView:

private void getAdresses(Location location) { // TODO
    double lat = location.getLatitude();
    double lng = location.getLongitude();
    Geocoder geocoder = new Geocoder(this, Locale.GERMAN);

    try {
        List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
        if (addresses.size() != 0) {
            Address address = addresses.get(0);

            String addressString = address.getAddressLine(0).toString();
            System.out.println("(geocoder) " + addressString);
            textView.append(addressString + "\n");

            Cursor cursor = mDbHelper.getAllEntrys("tblBar", "Adresse",
                    addressString);

            if (cursor.moveToFirst()) {

                String cursorContent = cursor.getString(cursor
                        .getColumnIndexOrThrow("Name"));
                textView.append(cursorContent + "\n");

            } else {
                System.out.println("No bar at current location");
            }
        } else {
            System.out.println("(geocoder) no address!");
        }
    } catch (IOException e) {
        System.out.println(e.toString() + "(geocoder)");
    }
}

Furthermore this is my method for calling the actual query on the database:

public Cursor getAllEntrys(String table, String column, String search) {
    try {
        String sSelect = "SELECT * FROM " + table + " WHERE " + column
                + " = '" + search + "'";
        Cursor cursor = mDb.rawQuery(sSelect, null);

        if (cursor != null) {
            cursor.moveToFirst();
        }
        return cursor;
    } catch (SQLException mSQLException) {
        System.out.println("getData >>" + mSQLException.toString());
        throw mSQLException;
    }
}

Hope someone can help me with this. Many thanks in advance!

    Okay guys first i want to thank all of you for your quick responses. Keep it up! Although the answer is quite obvious, i figured it out myself. The problem in the tutorial from: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/ is, that it doesn’t consider the case that you add values manually (Updates in the SQLite Database Browser) to your database after you first run the programm. Thats what i did… So you have to write your own method to check if there were any changes since the last run. Hope anyone can need this 🙂
