显示预启动屏幕后，Buildozer 构建的应用程序崩溃
Buildozer built app crashes after showing the presplash screen
我是kivy的新手，这是我第一次用kivy构建，我使用google collab作为编译环境，错误是打开我的应用程序它加载并显示预启动画面然后崩溃，我也试过 adb 来获取日志，但它没有提供任何信息，
here is the link to the apk
这是我的应用代码

# Instead of doing:

#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
# This can be translated into:

#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#
# -----------------------------------------------------------------------------
# Profiles
#
# You can extend section / key with a profile
# For example, you want to deploy a demo version of your application without
# HD content. You could first change the title to add "(demo)" in the name
# and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
and log file ,I get from the adb logcat
而且，我认为 1460 与日志中的应用程序有关
,我用的是真我3 android 11
请帮忙，谢谢
我有一个使用 log.txt 的小窍门，
而不是这个，你可以使用实时日志，它只过滤 python log here is the command..
很难在 log.txt 中查找错误，最好的方法是搜索这些关键字。
没有模块，没有 NameError，Traceback，缩进错误
在设备上部署时过滤 python 日志的命令
buildozer android debug deploy run logcat | grep python
尝试安装特定的 kivy 版本。最好的版本是kivy 2.0.0rc4。您可以在用于编码的任何程序的插件部分下载它。默认 kivy 版本 kivy 2.0.0 有一个错误。这对我来说也很崩溃。所以在 buildozer.spec 中将其替换为：
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy==2.0.0rc4,kivymd==0.104.2
我是kivy的新手，这是我第一次用kivy构建，我使用google collab作为编译环境，错误是打开我的应用程序它加载并显示预启动画面然后崩溃，我也试过 adb 来获取日志，但它没有提供任何信息， here is the link to the apk

#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*

# -----------------------------------------------------------------------------
# Profiles
#
# You can extend section / key with a profile
# For example, you want to deploy a demo version of your application without
# HD content. You could first change the title to add "(demo)" in the name
# and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
and log file ,I get from the adb logcat 而且，我认为 1460 与日志中的应用程序有关 ,我用的是真我3 android 11 请帮忙，谢谢
我有一个使用 log.txt 的小窍门， 而不是这个，你可以使用实时日志，它只过滤 python log here is the command..
很难在 log.txt 中查找错误，最好的方法是搜索这些关键字。 没有模块，没有 NameError，Traceback，缩进错误
在设备上部署时过滤 python 日志的命令
buildozer android debug deploy run logcat | grep python
尝试安装特定的 kivy 版本。最好的版本是kivy 2.0.0rc4。您可以在用于编码的任何程序的插件部分下载它。默认 kivy 版本 kivy 2.0.0 有一个错误。这对我来说也很崩溃。所以在 buildozer.spec 中将其替换为：
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy==2.0.0rc4,kivymd==0.104.2
