使用Buildozer部署Kivy到移动设备上
来源:互联网 发布:软件进口关税税率 编辑:程序博客网 时间:2024/06/16 21:05
在安装好Buildozer软件之后,我们在包含main.py
的文件夹下运行buildozer init
这个命令,然后我们就会看到在该文件夹下有一个buildozer.spec
这个文件,这个文件主要是用来配置一系列设置用的,使用文本编辑器,Linux下使用vim编辑器打开。
下面是个例子:
[app]# (str) Title of your application 更改1title = Test# (str) Package name 更改2package.name = test# (str) Package domain (needed for android/ios packaging)package.domain = org.example# (str) Source code where the main.py livesource.dir = .# (list) Source files to include (let empty to include all the files)source.include_exts = py,png,jpg,kv,atlas# (list) Source files to exclude (let empty to not exclude anything)#source.exclude_exts = spec# (list) List of directory to exclude (let empty to not exclude anything)#source.exclude_dirs = tests, bin# (list) List of exclusions using pattern matching#source.exclude_patterns = license,images/*/*.jpg# (str) Application versioning (method 1)# version.regex = __version__ = '(.*)'# version.filename = %(source.dir)s/main.py# (str) Application versioning (method 2) 更改3version = 0.1# (list) Application requirements 更改4requirements = kivy# (str) Presplash of the application 更改5presplash.filename = %(source.dir)s/data/presplash.png# (str) Icon of the application 更改6icon.filename = %(source.dir)s/data/icon.png# (str) Supported orientation (one of landscape, portrait or all) 更改7orientation = all# (bool) Indicate if the application should be fullscreen or not 更改8fullscreen = 0## Android specific 更改9## (list) Permissionsandroid.permissions = INTERNET# (int) Android API to use 更改10android.api = 19# (int) Minimum API required (8 = Android 2.2 devices)# 更改11android.minapi = 9# (int) Android SDK version to use 更改12android.sdk = 20# (str) Android NDK version to use 更改13android.ndk = 9c# (bool) Use --private data storage (True) or --dir public storage (False)android.private_storage = True# (str) Android NDK directory (if empty, it will be automatically downloaded.)#android.ndk_path =# (str) Android SDK directory (if empty, it will be automatically downloaded.)#android.sdk_path =# (str) Android entry point, default is ok for Kivy-based app#android.entrypoint = org.renpy.android.PythonActivity# (list) List of Java .jar files to add to the libs so that pyjnius can access# their classes.

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
总共做了14个更改。
title
为了避免某些字符可能引起的不工作,最好避免过长的标题,太长的标题到时候也可能不适应在App的图标下。package.name
package.name只能是一个单词,只能是由ASCII字符或数字组成,不应该包含特殊字符。比如说,如果你的应用叫Test One,那么package name就应该写成 testone。package.domain
这个应该填写的是制作这个App的公司或个人的名称,domain+name将会成为该应用对于Android 或iOS的标识。source.dir
填写包含main.py这些文件的目录路径,默认是在buildozer.spec所在的目录。source.include_exts
设置将扩展名符合该规则的文件包含进来。如果想将所有属于你自己的扩展名文件包含进来,直接将该值设置为空值,这样就能将所有东西包含进来了。source.exclude_exts
跟上面相对应的,这里设置的是不将符合该规则扩展名的文件包含进来。source.exclude_dirs
这里设置的是不将符合该规则的目录包含进来。比如说,如果不想将tests和bin目录包含进来的话,就进行如下设置。
source.exclude_dirs = tests, bin
- version.regex
使用正则表达式去捕捉version.filename文件内的version信息。默认的捕捉方法是在main.py里面查找类似下面一行的内容。
__version__ = "1.0"
version.filename
默认是指main.py文件version
用来自己手动设置version,如果你不想用捕捉的方法获取到version的话,你可以将version.regex 和 version.filename给注释掉,然后给version赋一个值,例如。
# version.regex =# version.filename =version = 1.0
requirements
填写该App所需要的Python的模块或扩展模块presplash.filename
Presplash是应用刚打开加载时显示的图像,对于不同的平台presplash可能会有不同的要求,目前Buildozer在该方面对于Android的支持要好于iOS。图片的类型必须是JPG或PNG的,最好是2次幂的尺寸,比如说512X512类型的图片对于所有的机器运行都很好。Presplash图片是不会自己适应、伸缩屏幕的,如果提供在尺寸的图片,可能就不适合在小屏幕的机器上显示。icon.filename
应用的图标,作为图标的图片必须是512X512而且是PNG格式的,这样才能够适应很多平台的要求。orientation
指明该App支持的显示方向,默认是landscape(横向显示),也可以更改为portrait(竖向显示)或者是全部。fullscreen
该值为布尔类型的,默认是true,这样App就会运行在全屏的状态了,意味着状态栏将会被隐藏。如果想要让用户能够看到状态栏、时间、通知等内容的话,就应该将该值设置为0。
