private String cursorToString(Cursor crs) {
    JSONArray arr = new JSONArray();
    crs.moveToFirst();
    while (!crs.isAfterLast()) {
        int nColumns = crs.getColumnCount();
        JSONObject row = new JSONObject();
        for (int i = 0 ; i < nColumns ; i++) {
            String colName = crs.getColumnName(i);
            if (colName != null) {
                String val = "";
                try {
                    switch (crs.getType(i)) {
                    case Cursor.FIELD_TYPE_BLOB   : row.put(colName, crs.getBlob(i).toString()); break;
                    case Cursor.FIELD_TYPE_FLOAT  : row.put(colName, crs.getDouble(i))         ; break;
                    case Cursor.FIELD_TYPE_INTEGER: row.put(colName, crs.getLong(i))           ; break;
                    case Cursor.FIELD_TYPE_NULL   : row.put(colName, null)                     ; break;
                    case Cursor.FIELD_TYPE_STRING : row.put(colName, crs.getString(i))         ; break;
                    }
                } catch (JSONException e) {
                }
            }
        }
        arr.put(row);
        if (!crs.moveToNext())
            break;
    }
    crs.close(); // close the cursor
    return arr.toString();
}
