带有2个GUI的P4a Kivy相机

Question

I'm a newbie here, so please, be gentle. I'd like to use the kivy built-in android camera, so that after taking the picture, I'd like to use another GUI. The app runs well on Ubuntu, but no camera. When I package it, it is successful, but after installing it immediately crashes.

Here is a snippet:

import kivy
from PIL import Image
from math import trunc
from PIL.ExifTags import TAGS
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder
from kivy.uix.floatlayout import FloatLayout


Builder.load_string("""
<CAM_GUI>:
    BoxLayout:
        orientation: 'vertical'
        Camera:
            id: camera
            resolution: (960, 1280)
            play: False
        Button:
            text: 'Shoot!'
            on_press: root.shoot()
            size_hint_y: None
            height: '48dp'
<GUI>:

        spacing: 10

    app.run()

Could you help me, please? Thank you very much in advance! :)

Answer 1

ImportError: No module named PIL

is somewhere near the end of the log. Put that package into requirements, package again and run then.

For better log (cleaner, shorter) use:

adb logcat -c && adb logcat
<run app>
<app crashes>
Ctrl + C
