This is a small code snippet that shows how powerful is the location module. Location-based applications are very attractive and very powerful. So this article presents an example that shows you how to play a song repeatedly when the cell id changes.

Initially, when the application starts it plays a song, and when the cell id changes the applications plays the song again right from the beginning.

Using songs is just an example of what could be done automatically when the current cell id changes.

Code

import location
import appuifw
import e32
import audio
 
class LocationInformerApp:
    def __init__(self):
        self.lock=e32.Ao_lock()
        self.exitflag = 0
        self.old_exit_key_handler=appuifw.app.exit_key_handler
        self.old_app_body=appuifw.app.body
        appuifw.app.exit_key_handler=self.set_exit
        appuifw.app.title = u'Wiki Code'
 
    def set_exit(self):
        appuifw.app.body = self.old_app_body
        self.exitflag=1
 
    
        
    def run(self):
        print u'*** Location Log ***'
        prevLoc = u''
        while not self.exitflag:
            if prevLoc <> location.gsm_location():
                print location.gsm_location()[3]
                p = audio.Sound.open("c:\\test.mp3")   #open the soundfile to play
                p.play()     # play the sound file for three times this is optional
            prevLoc = location.gsm_location()
            e32.ao_sleep(0.1)
 
 
 
appuifw.app.screen='normal'
lapp=LocationInformerApp()
lapp.run()
