【问题描述】：
我使用 plyer 开发 kivy 应用程序。通过buildozer构建并在android上启动应用程序成功，但是当我按下启动相机的按钮时应用程序崩溃，并且logcat中没有任何输出。当我在 kivylauncher 中执行相同的代码时，我的工作没有问题。即使我用加速度计测试它也是相似的。
我认为当我使用 plyer 构建应用程序时，必要的设置可能会很短。
--- source code ---
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.label import Label
from plyer import camera
class UI(FloatLayout):
def __init__(self, **kwargs):
super(UI, self).__init__(**kwargs)
self.lblCam = Label(text="Click to take a picture")
self.add_widget(self.lblCam)
def on_touch_down(self, e):
try:
print('test')
camera.take_picture('/storage/sdcard0/example.jpg', self.done)
except NotImplementedError:
print("This feature has not yet been implemented for this platform")
except Exception as e:
print(str(type(e)))
def done(self, e):
self.lblCam.text = e
class Camera(App):
def build(self):
ui = UI()
return ui
def on_pause(self):
return True
def on_resume(self):
pass
Camera().run()
