python-3.x – How to test the application with KivyMD?

Question:

I developed a small testing app that checks both battery status and whether the phone is charging.

The app is running locally from python main.py , but when I install it in Android Studio emulator , the software starts and closes.

Update

The Android package is being generated with buildozer

buildozer.spec (settings only)

[app]
title = My Test
package.name = mytest
package.domain = org.test
source.dir = .
source.include_exts = py,png,jpg,kv,atlas
source.exclude_exts = spec
version = 0.1
requirements = python3, kivy==2.0.0, kivymd==0.104.1, sdl2_ttf == 2.0.15
icon.filename = %(source.dir)s/data/icon.png
orientation = portrait
osx.python_version = 3
osx.kivy_version = 1.9.1
fullscreen = 0
android.permissions = BATTERY_STATS
android.arch = armeabi-v7a

[buildozer]
log_level = 2
warn_on_root = 1

End of update

I understand that the problem is when I use kivimd , with kivy it worked.

follow the code

mytest.kv

#:import MDLabel kivymd.uix.label
#:import MDBoxLayout kivymd.uix.boxlayout
#:import MDFloatLayout kivymd.uix.floatlayout
#:import MDTextButton kivymd.uix.button

<Page>:
    lbl1: lbl1
    lbl2: lbl2
    MDFloatLayout:
        MDTextButton:
            center: root.center
            size_hint_y: None
            pos_hint: {'y': .5}
            text: "Battery Status"
            on_press: root.get_status()
        MDBoxLayout:
            size_hint_y: None
            pos_hint: {'y': .1}
            MDLabel:
                text: "Is Charging?"
            MDLabel:
                id: lbl1
                text:
            MDLabel:
                text: "Percentage"
            MDLabel:
                id: lbl2
                text:

main.py

from kivymd.app import MDApp
from kivymd.uix.boxlayout import MDBoxLayout

from plyer import battery


class Page(MDBoxLayout):

    def get_status(self, *args):
        self.lbl1.text = str(battery.status['isCharging'])
        self.lbl2.text = str(battery.status['percentage']) + "%"


class MyTest(MDApp):

    def build(self):
        return Page()

    def on_pause(self):
        return True


if __name__ == "__main__":
    app = MyTest()
    app.run()

Note : Substituting from kivymd to kivy and substituting from MD to , works.

If you need more information, please comment on the post.

Answer:

I had the same problem: a simple application that didn't work on android with kivymd, but that worked with kivy. I managed to solve the problem by changing the requirements in buildozer.spec (according to the kitchen_sink demo on github):

requirements = python3,kivy==2.0.0,https://github.com/kivymd/KivyMD/archive/master.zip,certifi,pillow

Where it is commented: "(str) Custom source folders for requirements. Sets custom source for any requirements with recipes" uncomment and change from kivy to kivymd:

requirements.source.kivymd = ../../kivymd
