trying to get coords from database but nothing happens

as you can see from the code below im just trying to get the coords pushed out to the logcat. however i never see the message or the coords. it shows me the sql string then finishes. so i believe the try is failing but even the catch statement doesnt return anything.

Button ButtonMap = (Button) findViewById(R.id.ButMap);
   ButtonMap.setOnClickListener(new View.OnClickListener() {

          publ开发者_如何学Pythonic void onClick(View v) {
           try {
         /* Query for some results with Selection and Projection. */
            String sql = "SELECT _id,Longitude,Latitude FROM " + MY_DATABASE_TABLE + " WHERE _id = "+ID;
          Cursor c = db.rawQuery(sql,null);
           //db.query(MY_DATABASE_TABLE, new String[] {"_id", "Longitude", "Latitude"}, 
                      // "_id = " + "'%"+ID+"%'", null, null, null, null);
                  Log.e("SQL Select", sql);


         /* Get the indices of the Columns we will need */
         int longitude, latitude ;
            longitude = c.getColumnIndex("Longitude");
            latitude = c.getColumnIndex("Latitude");

         /* Check if our result was valid. */
          if (c.moveToFirst()) {
           int i = 0;
           /* Loop through all Results */ 
           do {
            i++;
            /* Retrieve the values of the Entry
             * the Cursor is pointing to. */
             double lat = c.getDouble(latitude);
              double lon = c.getDouble(longitude);            
                         Log.e("GPS", "location for this record is: lat="+lat+", lon="+lon);

           } while (c.moveToNext());
          }

        } catch (Throwable t) {
                  Log.e("GPS", t.toString());
       }
           finally {
         if (db != null)
          db.close();
        }

            Intent intent = new Intent();
                 setResult(RESULT_OK, intent);
                 finish();

       }

      });
 }
