我使用 Python 中的 Kivy 库创建了一个应用程序。该应用程序的目的是使用我的 API 从 YouTube 下载音乐。当我运行 main.py 文件时，该应用程序在我的桌面上运行良好。然而，在使用 buildozer 将应用程序构建到 APK 并将其安装到我的 Android 智能手机上后，应用程序在显示图像后立即崩溃。
这是我的 main.py 文件：
from kivy.lang import Builder
from kivy.uix.recycleview import RecycleView
from googleapiclient.discovery import build
from pytube import YouTube
from kivymd.app import MDApp
from kivymd.uix.button import MDFillRoundFlatButton

if not query.strip():

api_key = '<my-api-key'
youtube = build('youtube', 'v3', developerKey=api_key)
request = youtube.search().list(

)
response = request.execute()
results = []
for item in response['items']:

dialog = MDDialog(title='Finished Downloading', text='Enjoy your music!')
dialog.open()
if __name__ == "__main__":
MusicDownloaderApp().run()
这是我的 buildozer.spec 文件：
[app]
# (str) Title of your application
title = Music Downloader
# (str) Package name
package.name = musicdownloader
# (str) Package domain (needed for android/ios packaging)
package.domain = org.test
# (str) Source code where the main.py live
source.dir = .
# (list) Source files to include (let empty to include all the files)
source.include_exts = py,png,jpg,kv,atlas
# (str) Application versioning (method 1)
version = 0.1
# (list) Application requirements
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy,kivymd,pytube,google-api-python-client
# (str) Presplash of the application
presplash.filename = /content/download.png
# (str) Icon of the application
icon.filename = /content/download.png
#
# OSX Specific
#
#
# author = © Copyright Info
# change the major version of python used by the app
osx.python_version = 3
# Kivy version to use
osx.kivy_version = 1.9.1
#
# Android specific
#
# (bool) Indicate if the application should be fullscreen or not
fullscreen = 0
# (list) Permissions
# (See https://python-for-android.readthedocs.io/en/latest/buildoptions/#build-options-1 for all the supported syntaxes and properties)
android.permissions = INTERNET,WRITE_EXTERNAL_STORAGE
#
# iOS specific
#
# (str) Path to a custom kivy-ios folder
#ios.kivy_ios_dir = ../kivy-ios
# Alternately, specify the URL and branch of a git checkout:
ios.kivy_ios_url = https://github.com/kivy/kivy-ios
ios.kivy_ios_branch = master
# Another platform dependency: ios-deploy
# Uncomment to use a custom checkout
#ios.ios_deploy_dir = ../ios_deploy
# Or specify URL and branch
ios.ios_deploy_url = https://github.com/phonegap/ios-deploy
ios.ios_deploy_branch = 1.10.0
# (bool) Whether or not to sign the code
ios.codesign.allowed = false
我尝试过的：
我检查了 logcat 日志，但找不到与崩溃相关的任何特定错误。 我已确保在 buildozer.spec 文件中声明了必要的权限（INTERNET 和 WRITE_EXTERNAL_STORAGE）。 我已验证所需的库（kivy、kivymd、pytube、google-api-python-client）包含在 buildozer.spec 文件的要求部分中。 我已经确认 APK 安装成功，没有任何错误或警告。
我不确定是否需要对我的 main.py 或 buildozer.spec 文件进行任何更改来解决此问题。
任何建议或指导将不胜感激。
