26. Beispiel „Versenden einer SMS“ (1) Source Code import appuifw import messaging data = appuifw.query(u &quot;what are you doing?&quot; , &quot;text&quot; ) receiver = &quot;+49172940****&quot; if appuifw.query(u &quot;Send message?&quot; , &quot;query&quot; ) == True : messaging.sms_send(receiver, data) appuifw.note(u &quot;Message sent.&quot; , &quot;info&quot; ) else : appuifw.note( u&quot;Messages not sent!&quot; , &quot;info&quot; ) s60test.send_sms.py

27. Beispiel „Versenden einer SMS“ (2) Ausführung

28. Beispiel „Versenden einer SMS“ (3) Erfolgskontrolle beim Empfänger

30. Beispiel „SMS-Empfang und Sound“ (2) Source Code: Sound-Operationen class SoundRecorder: filename = 'e:boo.wav' # Drive E: is SD card mySound = None def record(self): self.mySound = audio.Sound.open(self.filename) self.mySound.record() def play(self): try : self.mySound = audio.Sound.open(self.filename) self.mySound.play() except : appuifw.note(u &quot;No sound recorded!&quot; , &quot;error&quot; ) def stop(self): if self.mySound: self.mySound.stop() self.mySound.close() def clear(self): self.stop() os.remove(self.filename)

31. Beispiel „SMS-Empfang und Sound“ (3) Source Code: SMS-Empfang recorder = SoundRecorder() def message_received(msg_id): box = inbox.Inbox() sms_text = box.content(msg_id) appuifw.note(u &quot;sms content: &quot; + sms_text , &quot;info&quot; ) if sms_text == &quot;play&quot; : recorder.play() elif sms_text == &quot;record&quot; : recorder.record() elif sms_text == &quot;stop&quot; : recorder.stop() elif sms_text == &quot;clear&quot; : recorder.clear() app_lock.signal() box = inbox.Inbox() box.bind(message_received)

32. Beispiel „Kamera und File-Upload“ (1) Aufnahme von Bildern import time import appuifw import camera filename = time.strftime( &quot;n95-%Y%m%d%H%M%S.jpg&quot; , time.gmtime()) image = camera.take_photo() image.save(filename) appuifw.note(u &quot;Photo saved to %s&quot; % filename, 'info' ) if imageToURL(filename) == 200: appuifw.note(u &quot;Photo uploaded successfully.&quot; , 'info' ) else : appuifw.note(u &quot;Photo upload failed!&quot; , 'error' )

33. Kamera-Einstellungen Optionen von camera.take_photo() def take_photo( mode= 'RGB16' , size=(640, 480), zoom=0, flash= 'none' , exposure= 'auto' , white_balance= 'auto' ):

34. Beispiel „Kamera und File-Upload“ (2) Hochladen auf Server mit httplib import httplib, urllib, base64, os.path def imageToURL(aPath): data = open(aPath, 'rb' ).read() # read binary data of picture encodedData = base64.encodestring(data) # encoded it to base64 headers = { &quot;Content-type&quot; : &quot;application/x-www-form-urlencoded&quot; , &quot;Accept&quot; : &quot;text/plain&quot; ,} params = urllib.urlencode({u 'fileName' : os.path.split(aPath)[1], u 'data' :encodedData}) conn = httplib.HTTPConnection( &quot;www.onyame.de&quot; ) conn.request( &quot;POST&quot; , &quot;/image_uploader.php&quot; , params, headers) response = conn.getresponse() conn.close() return response.status Quelle: http://wiki.forum.nokia.com/index.php/How_to_upload_a_file_to_server_with_application/x-www-form-urlencoded

37. Beispiel „Mandelbrot-Menge“ (1) Rahmenprogramm import e32 from appuifw import * app.screen = 'full' app.body = canvas = Canvas() width, height = canvas.size xaxis = width/2 yaxis = height/1.5 scale = 60 iterations = 25 # <<iteration>> lock = e32.Ao_lock() app.exit_key_handler = lock.signal lock.wait()

38. Beispiel „Mandelbrot-Menge“ (2) Iterationsschleife for y in range(height): for x in range(width): magnitude = 0 z = 0+0j c = complex(float(y-yaxis)/scale, float(x-xaxis)/scale) for i in range(iterations): z = z**2+c if abs(z) > 2: v = 765*i/iterations if v > 510: color = (255, 255, v%255) elif v > 255: color = (255, v%255, 0) else : color = (v%255, 0, 0) break else : color = (0, 0, 0) canvas.point((x, y), color) e32.ao_yield()

39. Beispiel „Kontakte-Datenbank“ import contacts db = contacts.open() print u &quot;Searching contacts…&quot; found = db.find( 'guy' ) # search in name, email, etc. for guy in found: firstname = guy.find( 'first_name' )[0].value company = guy.find( 'company_name' )[0].value email_address = guy.find( 'email_address' )[0].value print u &quot;%s %s %s&quot; % (firstname, company, email_address)

41. Beispiel „Bewegungssensor“ (1) Abfrage der Beschleunigungssensoren import sensor sensors = sensor.sensors() # Does this device have Accelerator Sensor if sensors.has_key( 'AccSensor' ): SENSOR_ACC = True sensor_data = sensors[ 'AccSensor' ] sensor_acc = sensor.Sensor(sensor_data[ 'id' ], sensor_data[ 'category' ]) sensor_acc.connect(handle_sensor_raw) def handle_sensor_raw(a_data): if a_data.has_key( 'data_1' ): acc_data_1 = a_data[ 'data_1' ] acc_data_2 = a_data[ 'data_2' ] acc_data_3 = a_data[ 'data_3' ]
