所有mp3文件和main.py都位于buildozer文件夹中. 这是日志.
解决方案
当我的应用程序崩溃时，我发现了一条回溯说NoneType object has no attribute 'state'.所以我确保有一个
if <SOUND_FILE>:
<SOUND_FILE>.play() # <SOUND_FILE>.state = 'play' | <SOUND_FILE>.stop()
每当我想更改音频状态时.现在，我可以在Android设备上打开我的应用并使用，但是音频不会播放.这就是我当前要解决的问题.我认为音频文件始终为None.因此，如果您想在apk 和中包含mp3文件，并且希望您的应用不会在Android设备上崩溃，则可以尝试. /p>
I created a simple App. When pressed on a button to play a mp3 file. It works in terminal but when I compile it with buildozer and install on an android device only splash image appears and then app crashes and device returns to main screen.

All the mp3 files and main.py are in the buildozer folder. Here is the logcat.
解决方案
When my app crashed, I found a traceback saying NoneType object has no attribute 'state'. So I made sure there was an
if <SOUND_FILE>:
<SOUND_FILE>.play() # <SOUND_FILE>.state = 'play' | <SOUND_FILE>.stop()
whenever I wanted to change the state of the audio. Now I can open my app on an Android device and use it, but the audio won't play. That's what I'm trying to fix currently. I'm thinking the audio files are always None. So if you want to have mp3 files in your apk and you want your app to not crash on an Android device, you can try what I did.
这篇关于简单的kivy应用程序按下按钮无法在Android设备上播放mp3的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
