利用Python开发App实战
说在前面的话
准备工作
搭建kivy开发环境
install kivy for mac
brew install pkg-config sdl2 sdl2_image sdl2_ttf sdl2_mixer gstreamer
pip install cython==0.25
pip install kivy
git clone https://github.com/kivy/kivy
python setup.py install
$python
Python 2.7.10 (default, Jul 15 2017, 17:16:57)

用kivy开发第一个python app
#! -*- coding:utf-8 -*-
from kivy.app import App
class HelloApp(App):
pass
if __name__ == '__main__':
HelloApp().run()
Label:
text: 'Hello, World! I am nMask'
运行第一个python app
python main.py
安装buildozer工具
pip install buildozer
使用buildozer工具将kivy程序打包成apk
buildozer init
buildozer android debug deploy run
python apk程序测试
buildozer使用说明
Usage:
buildozer [--profile
] [--verbose] [target] ... buildozer --version
Available targets:
android Android target, based on python-for-android project
ios iOS target, based on kivy-ios project
android_old Android target, based on python-for-android project (old toolchain)
Global commands (without target):
distclean Clean the whole Buildozer environment.
help Show the Buildozer help.
init Create a initial buildozer.spec in the current directory
serve Serve the bin directory via SimpleHTTPServer
setdefault Set the default command to run when no arguments are given
version Show the Buildozer version
Target commands:
clean Clean the target environment
update Update the target dependencies
debug Build the application in debug mode
release Build the application in release mode
deploy Deploy the application on the device
run Run the application on the device
serve Serve the bin directory via SimpleHTTPServer
Target "android_old" commands:
adb Run adb from the Android SDK. Args must come after --, or
use --alias to make an alias
logcat Show the log from the device
Target "ios" commands:
list_identities List the available identities to use for signing.
xcode Open the xcode project.
Target "android" commands:
adb Run adb from the Android SDK. Args must come after --, or
use --alias to make an alias
logcat Show the log from the device
p4a Run p4a commands. Args must come after --, or use --alias
to make an alias
