实际上我正在尝试kivy音频，它在linux上运行良好但是当我制作它的apk并在android中测试然后应用程序崩溃。这是代码和日志。
代码： -
import glob
import os
from kivy.app import App
from kivy.uix.relativelayout import RelativeLayout
from kivy.lang import Builder
from kivy.core.audio import SoundLoader
Builder.load_string('''
<hey>:
RelativeLayout:
Button:
id:change
text:"hi"
on_press:root.yeah()
''')
class hey(RelativeLayout):
def yeah(self):
#k = glob.glob("/root/.")
k=glob.glob('/sdcard/shivam.mp3')
print(k)
self.ids.change.text="%s"%k
self.song=SoundLoader.load('/sdcard/shivam.mp3')
return self.song.play()
class hello(App):
def build(self):
return hey()
hello().run()

如何删除此错误？我认为这里Soundloader没有加载mp3文件。之前有人通过kivy试过Android的音频和视频吗？需要帮助
答案 0 :(得分：0)
在 buildozer.spec 文件的要求中添加 ffpyplayer。同样在代码的开头添加行 os.environ["KIVY_AUDIO"] = "ffpyplayer"
它对我有用。
