kivy打包虚拟机,手机软件运行日志等经验分享,一个电话号码查询小应用实例

我是python小白一枚,对kivy开发手机app产生了兴趣,并没感觉到kivy写代码有多难,折腾打包成手机apk倒是花了好长时间,走过了大大小小的坑,这里把经验记录下来,供大家参考。

kivy打包有几种方法,可以自己配置环境,通过python for android(p4a),或者buildozer打包,也可以使用别人配置好环境的虚拟机打包。配置环境坑实在太多了,建议直接研究使用虚拟机打包,省时省力,把更多精力用在代码上吧。

我打包用的虚拟机是某大佬做的,网址是:https://github.com/nkiiiiid/kivy-apk

虚拟机解压安装后占将近50GB空间,如果电脑硬盘不够用,可以下载到移动硬盘上,安装在移动硬盘上。

具体的使用方法,上面的网页有详细说明。

手机软件运行日志查看方法,大佬们用的都是mumu模拟器,操作太复杂了,小白的我实在不爱花那么多时间研究了,就用了另一个简单点的笨方法,在ubuntu系统上安装好adb环境后,按以下步骤操作就能查看日志了:

1. 手机打开开发者模式
2. 开发者模式里面打开USB调试
3. 电脑下载adb工具
4. 手机连接电脑
5. 电脑adb devices看到有设备
6. 电脑adb shell logcat -s python
7. 手机打开APP

再说说打包的配置文件修改吧,buildozer.spec是打包失败的祸根,很多手机上失退,打包失败都可能是配置不对造成的。遇到失败或闪退,首先查看手机运行日志,其次认真在buildozer.spec上找原因。下面附上一个我打包用过的buildozer.spec供参考,不同的应用程序在打包时都要相应地修改配置文件上的参数

# -----------------------------------------------------------------------------
# List as sections
#
# You can define all the "list" as [section:key].
# Each line will be considered as a option to the list.
# Let's take [app] / source.exclude_patterns.
# 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

特别要强调一下,requirements这个配置参数中一定要把你打包要含的文件扩展名全写进去,否则会出错。permissions参数非常重要,如果使用网络,使用存储空间或者用到其它权限,一定要在这里声明,否则肯定闪退,关于权限,网上有其它很详细的中文贴子,大家可以参考。

我在应用程序中使用了bs4库,但打包时在requirements中写上bs4闪退了,后来听大佬建议改成全称beautifulsoup4,就成功了。反正是,各种坑,大家过了入门这个阶段,就一片光明了。

下面我把我调试成功,能在手机上正确运行的一个应用发在这里,供大家参考,程序中涉及到ScrollView,中文字体使用,ScreenManager等多个技术点,虽然是小应用,但可以参考。

  最后还要分享一个经验,上面的手机应用程序打包安装到手机上后,可能会遇到无法在人名输入框中使用输入法的问题,可以这样子解决:


      如果是华为手机:设置--系统--语言和输入法--安全输入,把这个安全输入关掉,就行了 
      根本的解决方式应该是:
Kivy 除了设置中文字体,真正支持中文IME输入还需要替换SDL2.dll,修改SDL_windowskeyboard.c代码,定位到IME_Init 函数 videodata->ime_uiless = UILess_SetupSinks(videodata); 语句,注释掉,重新编译生成dll并替换。
上两行是我转贴过来的,我小白的水平解决不了,就用手机设置的方式暂时对付,哪位大佬能修改SDL2.dll成功,分享经验给我啊
上面代码在手机上的运行效果如下:
