Kivy- Android上截图[screenshot()]保存在哪里？

Question

我遇到了一个大问题，就是在我的安卓手机上使用 screenshot() 这个功能时，我不知道截图保存在哪里。我查看了 /storage/emulated/0/Android/data 这个文件夹，但什么都没找到。那里甚至没有我这个应用的文件夹。

另外，有没有办法设置截图保存的位置？也许可以保存到一个更合理的地方。

这是我的代码：

from random import random
from kivy.uix.widget import Widget
from kivy.uix.button import Button
from kivy.graphics import Color, Ellipse, Line
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.anchorlayout import AnchorLayout
from kivy.uix.stacklayout import StackLayout
from kivy.clock import Clock
from kivy.uix.slider import Slider
from kivy.core.window import Window


thickness = 5

class MyPaintWidget(Widget):

    def on_touch_down(self, touch):
        color = (random(), 1, 1)
        with self.canvas:
            Color(*color, mode='hsv')
            touch.ud['line'] = Line(points=(touch.x, touch.y), width = thickness)

    def on_touch_move(self, touch):
        if 'line' in touch.ud:
            touch.ud['line'].points += [touch.x, touch.y]







class MyPaintApp(App):

    def build(self):
        #layouts
        w = Widget()
        b = BoxLayout()
        f = FloatLayout()
        a = AnchorLayout(anchor_x= 'left', anchor_y= 'bottom')
        s = StackLayout()
        #widgets
        p = MyPaintWidget()
        cb = Button(text='Clear')
        lb = Button(pos = (150,0), text = "Large\nBrush", halign = "center")
        mb = Button(pos = (300,0), text = "Medium\nBrush", halign = "center")
        sb = Button(pos = (450,0), text = "Small\nBrush", halign = "center")
        svb = Button(pos = (600, 0), text = "Save", halign = "center")

        #adding the widgets
        w.add_widget(p)
        w.add_widget(cb)
        w.add_widget(lb)
        w.add_widget(mb)
        w.add_widget(sb)
        w.add_widget(svb)
        #w.export_to_png('ScreenShot.png')



        #bindings
        def clear_canvas(obj):
            p.canvas.clear()
        cb.bind(on_release=clear_canvas)

        def large_brush(obj):
            global thickness
            thickness = 15
        lb.bind(on_release=large_brush)

        def medium_brush(obj):
            global thickness
            thickness = 10
        mb.bind(on_release=medium_brush)

        def small_brush(obj):
            global thickness
            thickness = 5
        sb.bind(on_release=small_brush)


        def Screenshot(obj):
            global Screenshotnum
            Window.screenshot(name="Screenshot.png")

        svb.bind(on_release=Screenshot)


        return w


if __name__ == '__main__':
   MyPaintApp().run()`

可以忽略 "export_to_png" 这一部分。
