python-for-android简称p4a是kivy应用打包成apk的一种方法，使用p4a需要手动下载Android SDK和Android NDK的安装包，随后安装构建工具，配置SDK和NDK的环境变量，值得注意的是该方法只能在Linux平台上打包，关于安装和p4a的介绍，可以参考https://python-for-android.readthedocs.io/en/latest/,如果需要本课程将提供一个已经完全设置好的虚拟机，该虚拟机来源于《Python+kivy(App开发)从入门到实践》

1.基于Kivy开发的涂鸦画板项目的p4a安卓打包及项目演示

首先通过如下命令清除其他apk中的builds和dists文件夹，对于同一个apk,该命令只执行一次即可。

p4a clean_builds && p4a clean_dists kivydev@kivydev-VirtualBox:~/test/paint$ p4a clean_builds && p4a clean_dists [INFO]: Reading .p4a configuration [INFO]: Recipe python3crystax: version "3.6" requested [INFO]: Reading .p4a configuration [INFO]: Recipe python3crystax: version "3.6" requested

自动生成的.p4a文件，如下：

--dist_name Paint --android_api 19 --minsdk 19 --sdk_dir /home/kivydev/andr/android-sdk-linux --ndk_dir /home/kivydev/andr/crystax-ndk-10.3.2 --arch armeabi-v7a --requirements python3crystax==3.6,kivy --private . --package com.xujing.paint --name paint --version 1.0 --orientation landscape --bootstrap sdl2 --icon icon.png

随后通过以下命令打包apk

p4a apk --debug [INFO]: Reading .p4a configuration [INFO]: Recipe python3crystax: version "3.6" requested [INFO]: Will compile for the following archs: armeabi-v7a [INFO]: Getting Android API version from user argument [INFO]: Available Android APIs are (19, 23, 27) [INFO]: Requested API target 19 is available, continuing.

打包完成后会生成apk文件，把apk文件复制到共享文件夹，并在手机或安卓模拟器中安装。

2.MUMU安卓模拟器及adb_server.exe调试

我们将打包好的apk文件安装在安卓模拟器，并通过安卓模拟器提供的adb_server.exe多apk进行调试

首先我们将刚刚打包好的apk文件安装到安卓模拟器：

打开我们安装的安卓程序

可以正常工作。

我们通过MUMU安卓模拟器自带的adb_server.exe调试看一下后台运行的日志

cmd cd D:\soft_xj\MUMU\emulator\nemu\vmonitor\bin adb_server.exe connect 127.0.0.1:7555 adb_server.exe shell run-as com.xujing.paint cd files/app/.kivy/logs cat kivy_20-07-09_1.txt

没有ERROR同时我们的安卓程序并没有闪退，运行正常，如果过程中我们的程序出现闪退或错误，请按照上述方式进行调试，寻找原因。

3.adb安卓调试

最后我们将p4a打包的安卓程序安装运行在我们的华为安卓手机上，首先我们经apk安装在我们的华为手机上

我们使用adb调试我们安卓手机上的apk应用

adb shell run-as com.xujing.paint cd files/app/.kivy/logs cat kivy_20-07-09_1.txt
