Problem with location

[tmessers]

Hello everybody,
i have a problem using location.geocode.
By using a ui, i want to get the geocode of an
address.

Although from my view the dict is created properly,
the result, when operated by location.geocode is „None„.
I cant find my fault.
Does anybody else find it?

Thanks

import ui
import location


def button_tapped(sender):
	if sender.title == "Execute":
		adresse()
		
	elif sender.title == "Delete":
		tf1.text = ""
		tf2.text = ""
		tf3.text = ""
	
	elif sender.title == "Map":
		lon=float(tf1.text)
		lat=float(tf2.text)
		karte(lon,lat)

mg=20
w=200
h=30
mg1=((2*mg)+w)
mg2=((3*mg)+(2*w))
bw=200

def make_textfield(text,frame):
    return ui.TextField(text=text, frame=frame, bordered =True, clear_button_mode='always')

def make_button(title, frame):
    return ui.Button(title=title, frame=frame, bordered=True, border_width=2,   action=button_tapped)
    
v=ui.View(name='Koordinaten',bg_color='grey',tint_color='black',border_width=1)
tf1=make_textfield(text='Street',frame=(mg,((2*mg)+h),w,h))#tf1
v.add_subview(tf1)
tf2=make_textfield(text='City',frame=(mg1, ((2*mg)+h),w,h)) #tf2
v.add_subview(tf2)
tf3=make_textfield(text='Country',frame=(mg2, ((2*mg)+h),w,h)) #tf2
v.add_subview(tf3)
tf4=make_textfield(text='tf4',frame=(mg1, ((3*mg)+(2*h)),w,h)) #tf2
v.add_subview(tf4)
tf5=make_textfield(text='tf5',frame=(mg2, ((3*mg)+(2*h)),w,h)) #tf2
v.add_subview(tf5)

v.add_subview(make_button(title='Execute',frame=(mg,((8*mg)+(7*h)),w,h)))
v.add_subview(make_button(title='Delete',frame=(mg1,((8*mg)+(7*h)),w,h)))
v.add_subview(make_button(title='Map',frame=(mg2,((8*mg)+(7*h)),w,h)))
v.present()

def adresse():
	#print("addresse ok")
	road=tf1.text
	#print(strasse)
	town=tf2.text
	#print(stadt)
	land=tf3.text
	#print(land)
	addresse= {'Street': road, 'City': town, 'Country': land}
	print ("1: %s" %addresse)
	results = location.geocode(addresse)
	print ("1: %s" %results)
	if results != None:
		zwischen1=round(results[0]['latitude'],6)
		tf4.text=str(zwischen1)
		zwischen2=round(results[0]['longitude'],6)
		tf5.text=str(zwischen2)

@tmessers use

@ui.in_background
def adresse():

@tmessers and for a nicer TextField initialization, use placeholder

def make_textfield(text,frame):
    return ui.TextField(placeholder=text, frame=frame, bordered =True, clear_button_mode='always')

@cvp
Thank you, both hints worked well.
