怎么创建一个buildozer.spec文件

在Kivy开发中，使用Buildozer工具打包APK文件时需要一个名为buildozer.spec的配置文件。buildozer.spec文件可以手动创建，也可以使用buildozer init命令自动生成。

手动创建buildozer.spec文件的方法如下：

1. 在应用程序的根目录下创建一个名为buildozer.spec的文件。

2. 在文件中添加以下内容：

   [app]

   # (required) Title of your application
   title = My Application

   # (optional) Package name
   package.name = myapp

   # (optional) Package domain (needed for android/ios packaging)
   package.domain = org.test

   # (optional) Source code where the main.py live
   source.dir = .

   # (optional) Application versioning (method 1)
   version = 0.1

   # (optional) Application versioning (method 2)
   # version.regex = __version__ = ['"](.*)['"]
   # version.filename = %(source.dir)s/main.py

   # (optional) Application versioning (method 3)
   # version.git = git describe --tags --long
   # version.git.branch = False

   # (optional) Application dependencies
   # comma separated e.g. requirements = sqlite3,kivy
   # requirements = kivy

   # (optional) Custom source folders for requirements
   # Sets custom source for any requirements with recipes
   # as pkg1=../my_repos/pkg1,pkg2=../my_repos/pkg2
   # source.pkgs_dir = ../my_repos/

   # (optional) Android specific
   # (optional) Minimum API required (21 by default)
   # android.minapi = 21

   # (optional) Android specific
   # (optional) Target API to use, if different from minapi
   # android.api = 28

   # (optional) Android specific
   # (optional) Path to a custom AndroidManifest.xml
   # android.manifest = ./android/AndroidManifest.xml

   # (optional) Android specific
   # (optional) Space separated list of Java .jar files to add to the libs dir
   # android.add_jars = foo.jar,bar.jar

   # (optional) Android specific
   # (optional) Space separated list of Java .aar files to add to the libs dir
   # android.add_aars = foo.aar,bar.aar

   # (optional) Android specific
   # (optional) Gradle dependencies to add (currently only supports
   #         comma separated list of kv files)
   # android.gradle_dependencies = com.android.support:appcompat-v7:26.0.1

   # (optional) Android specific
   # (optional) Android logcat filters to use
   # android.logcat_filters = *:S python:D

   # (optional) Android specific
   # (optional) Android additional libraries to copy into libs/armeabi
   # android.libs_armeabi = mylibs/armeabi/libsqlite3.so

   # (optional) Android specific
   # (optional) Android additional libraries to copy into libs/armeabi-v7a
   # android.libs_armeabi_v7a = mylibs/armeabi-v7a/libsqlite3.so

   # (optional) Android specific
   # (optional) Android additional libraries to copy into libs/x86
   # android.libs_x86 = mylibs/x86/libsqlite3.so

   # (optional) Android specific
   # (optional) Android additional libraries to copy into libs/arm64-v8a
   # android.libs_arm64_v8a = mylibs/arm64-v8a/libsqlite3.so

   # (optional) Android specific
   # (optional) Add Java code to be used (can be copy/pasted) (must be valid Java)
   # android.add_java_to_build = 

   # (optional) Android specific
   # (optional) Gradle repositories to include
   # android.gradle_repositories = mavenCentral()

   # (optional) Android specific
   # (optional) Force the use of a pre-built python
   # android.use_pure_python = False

   # (optional) iOS specific
   # ios.ipa = myapp.ipa

   # (optional) iOS specific
   # ios.codesign.allowed = mac

   # (optional) iOS specific
   # ios.codesign.p12 = myapp.p12

   # (optional) iOS specific
   # ios.codesign.password = mypassword

   # (optional) iOS specific
   # ios.codesign.provisioning_profile = myapp.mobileprovision

   # (optional) iOS specific
   # ios.sdk = 10.1

   # (optional) OSX specific
   # osx.python_version = 3.7.1

   # (paths) Exclusions
   # comma separated filenames and regex values
   # exclude_patterns = __pycache__,*.pyc,.git,*venv*,.DS_Store,tests

   # (buildozer) Debugging options
   # log_level = 2
   # warn_on_root = 1

3. 在文件中，可以根据自己的需要修改各个参数的值。

4. 保存buildozer.spec文件。

如果你想使用buildozer init命令自动生成buildozer.spec文件，在应用程序根目录下打开命令行窗口，输入以下命令：

buildozer init

该命令会自动生成一个buildozer.spec文件，并根据你的Python环境和系统配置，自动设置各个参数的值。你可以在生成的buildozer.spec文件中修改各个参数的值以满足你的需求。
