mapview not working on Kivy 2.0.0

[kushurox]

Describe the bug
kivy garden, Map View doesn't Work on kivy version 2.0.0, I have tried it on 1.11.1 and the code worked.

To Reproduce
from kivy_garden.mapview import MapView, MapMarker
from kivymd.app import MDApp
from kivymd.uix.floatlayout import MDFloatLayout

class MapWidget(MDFloatLayout):
def init(self):
super(RealBoss, self).init()
m = MapView(zoom=11, lat=50.6394, lon=3.057, on_map_relocated=self.func)
self.add_widget(m)
marker = MapMarker(lat=50.6394, lon=3.057)
m.add_marker(marker)

def func(self, *args):
    print(args)

class Try(MDApp):
def build(self):
return MapWidget()

Try().run()

Expected behavior
a red marker to be placed on the map

# Now it's working well

from kivy_garden.mapview import MapView, MapMarker
from kivymd.app import MDApp
from kivymd.uix.floatlayout import MDFloatLayout

class MapWidget(MDFloatLayout):
    def __init__(self):
        super(MapWidget,self).__init__()
        m = MapView(zoom=11, lat=50.6394, lon=3.057, on_map_relocated=self.func)
        self.add_widget(m)
        marker = MapMarker(lat=50.6394, lon=3.057)
        m.add_marker(marker)

    def func(self, *args):
        print(args)
class Try(MDApp):
    def build(self):
        return MapWidget()

Try().run()

[kushurox]

it is still same.

I was having the same problem. I solved this by using my own source ".png".

marker = MapMarker(lat=50.6394, lon=3.057, source='newMarker.png')

[alexnaoki]

Using kivy==1.11.1, there is no problem with the marker's source. I believe there are some incompatibilities with kivy==2.0

[kushurox]

yeah the problem with 1.11.1 was that the md animations werent smooth. so i had to upgrade to 2.0.0

I have the same problem and I am a little confused about the issue is closed since it seems to be a real issue

[kushurox]

alright ill just keep it open until the mods close it

[Sahil-pixel]

i am facing same problem with kivy 2.0.0 but there is no problem with kivy==1.11.1

[runette]

What I ended up doing is downloading the whole of mapview into my project (it is neither very big nor does it change very fast - if at all) and then solving this problem by explicitly referencing the marker icon:

MapMarker(lat=self.lat, lon=self.lon, source='%path_to_icons%/Marker.png'))

where you do, of course, replace %path_to_icons% with the place that you put the mapview icons folder!

This issue is caused by the fact that Kivy 2.0.0 does not load the image if the default source value is not changed. I have created a pull request #47 resolving this.

[Ryan-Ashton]

That's great. Hopefully the pull request gets approved soon.
