SQLiteConstraintException nicht innerhalb Fang

Question

gehen Wenn ich diesen Code ausführen ich innerhalb des db.insert haben eine Ausnahme:

08-29 15:40:17.519: E/SQLiteDatabase(3599): android.database.sqlite.SQLiteConstraintException: column date is not unique (code 19) 

was normal ist, weil ich schon diesen Wert als Schlüssel. Also in diesem Fall mache ich einen Haken von SQLiteConstraintException, aber ich bekomme nie in den Fang, wenn ich den Code ausführen.

Was mache ich falsch?

  try { 
       db.insert(TABLE_STATISTICS, null, values); 
      } catch (SQLiteConstraintException e) { 
       Log.d("entered", "entered the exception"); 
       ContentValues valuesUp = new ContentValues(); 
       valuesUp.put((isMT ? KEY_MT : KEY_MO), change); 
       db.update(TABLE_STATISTICS, valuesUp, KEY_DATE + "=?", 
         new String[] { message_date }); 
      } 

Vielen Dank.

das ganze Protokoll:

Answer 1

Verwenden db.insertOrThrow() statt.
