問題描述

我正在使用 kivy 構(gòu)建一個(gè)應(yīng)用程序，它可以在我的 Linux 筆記本電腦上完美運(yùn)行.我使用 buildozer 為 android 構(gòu)建應(yīng)用程序，并且日志沒有顯示任何錯(cuò)誤.完成后，會在 bin 文件夾中創(chuàng)建 apk 文件.

然后我復(fù)制 apk 文件并將其粘貼到我的手機(jī)存儲中，然后安裝該應(yīng)用程序.

當(dāng)我打開應(yīng)用程序時(shí)，它會顯示 kivy 徽標(biāo)并正在加載……但隨后它崩潰了！我嘗試了一整天來尋找解決方案，但我無法實(shí)現(xiàn).

我在谷歌搜索問題時(shí)發(fā)現(xiàn)了這個(gè)命令，它應(yīng)該有助于調(diào)試，但我無法理解輸出！:

buildozer android logcat

這是我運(yùn)行此命令時(shí)打印的日志

此外，我嘗試在使用此命令運(yùn)行構(gòu)建時(shí)存儲整個(gè)日志:

buildozer android debug deploy run logcat >日志.txt

這是日志文件

此外，以下是我對默認(rèn) buildozer.spec 文件所做的更改:

編輯

這是 logcat 的輸出p>

Edit2:在解決了@inclement 解決的 no module found 錯(cuò)誤后，該應(yīng)用程序仍然在我的 Android 手機(jī)上崩潰.這是我在運(yùn)行應(yīng)用程序時(shí)收到的新 logcat

經(jīng)過幾天的調(diào)試，我終于找到了錯(cuò)誤，這是我在項(xiàng)目中使用的一些第三方庫引起的.很明顯kivy、buildozer或者python-for-android都解析不了這個(gè)(不知道是怎么打包的).

如果有人遇到這個(gè)問題，我強(qiáng)烈建議使用模擬器進(jìn)行調(diào)試，而不是依賴 logcat.就我而言，logcat 沒用.它沒有告訴我有關(guān)錯(cuò)誤的任何信息.

我需要逐步嘗試刪除依賴項(xiàng)，直到發(fā)現(xiàn)錯(cuò)誤.@inclement 的回答和評論也很有幫助.

I'm building an app using kivy and it works perfectly on my Linux laptop. I build the app for android using buildozer and the log does not show any errors. When it was complete, the apk file is created in the bin folder.

I then copy the apk file and paste it on my phone storage and then install the app.

When I open the app, it shows the kivy logo and loading... but then it crashes! I tried the whole day to find a solution but I could not achieve that.

I find this command while googling the problem and it should be helpful for debugging but I can't understand the output!:

buildozer android logcat

This is the log that gets printed when I run this command

Furthermore, I tried to store the whole log when running the build using this command:

buildozer android debug deploy run logcat > log.txt

here is the log file

Moreover, here are the changes that I made to the default buildozer.spec file:

[app]

# (str) Title of your application
title = Overall Translator

# (str) Package name
package.name = overallTranslator

# (str) Package domain (needed for android/ios packaging)
package.domain = org.nidhal.overallTranslator

# (list) Source files to include (let empty to include all the files)

# (list) Source files to exclude (let empty to not exclude anything)
source.exclude_exts = spec, txt, md, gitignore

# (list) List of directory to exclude (let empty to not exclude anything)
source.exclude_dirs = tests, bin, venv

# (list) List of exclusions using pattern matching

EDIT

here is the output of the logcat

Edit2: After resolving the no module found error adressed by @inclement, the app still crashes on my android phone. Here is the new logcat i receive when i run the app

After days of debugging, I finally find the error, which is caused by some third party libraries that I used in my project. Obviously, kivy, buildozer or python-for-android could not parse this (I don't know how the packaging is done).

If anyone is having this problem, I highly recommend debugging with an emulator and not relying on the logcat. In my case the logcat was useless. It did not tell me nothing about the error.

I needed to try step by step removing dependencies until I found the error. Answer and comment of @inclement were also helpful.

這篇關(guān)于Kivy 應(yīng)用程序使用 buildozer 成功構(gòu)建，但在 android 手機(jī)上打開時(shí)崩潰的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
