我从 Kivy 和 Android 开始，尝试制作一个应用程序，也使用 plyer 来访问设备传感器。

我正在与：

  • 基维：1.9.1
  • 构建器：0.32dev
  • SO（桌面）：Ubuntu 14.04 LTS
  • SO Android：棉花糖 6.0

我从网络教程中获取了以下代码：

#-*-coding:utf8;-*-
#qpy:2
#qpy:kivy

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.floatlayout import FloatLayout
from plyer import accelerometer
from kivy.clock import Clock

class UI(FloatLayout):
    def __init__(self, **kwargs):
        super(UI, self).__init__(**kwargs)
        self.lblAcce = Label(text="Accelerometer: ") #create a label at the center
        self.add_widget(self.lblAcce) #add the label at the screen
        try:
            accelerometer.enable() #enable the accelerometer
            Clock.schedule_interval(self.update, 1.0/24) #24 calls per second
        except:
            self.lblAcce.text = "Fallo al iniciar el acelerometro" #error

    def update(self, dt):
        txt = ""
        try:
            txt = "Aceleracion: \nX = %.2f\nY = %.2f\nZ = %2.f " %(
                accelerometer.acceleration[0], #read the X value
                accelerometer.acceleration[1], # Y
                accelerometer.acceleration[2]) # Z
        except:
            txt = "No se puede leer el acelerometro!" #error
        self.lblAcce.text = txt #add the correct text


class TestApp(App):
    def build(self):
        # display a button with the text : Hello QPython 
        usi = UI()
        return usi

if __name__== '__main__':
    TestApp().run()

并使用此 buildozer.spec 文件构建 APK（去掉注释块）：

[app]

# (str) Title of your application
title = Acelerometro 1

# (str) Package name
package.name = acc1

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

# (str) Source code where the main.py live
source.dir = .

# (list) Source files to include (let empty to include all the files)
source.include_exts = py,png,jpg,kv,atlas

# (str) Application versioning (method 1)
version = 1.0

# (list) Application requirements
# comma seperated e.g. requirements = sqlite3,kivy
requirements = kivy, plyer

# (str) Supported orientation (one of landscape, portrait or all)
orientation = all

# (bool) Indicate if the application should be fullscreen or not
fullscreen = 1

[buildozer]

# (int) Log level (0 = error only, 1 = info, 2 = debug (with command output))
log_level = 2

# (int) Display warning if buildozer is run as root (0 = False, 1 = True)
warn_on_root = 1

我忘了设置

android.permissions

但对此没有任何问题。问题是当我关闭（翻转）手机（从纵向到横向）时，应用程序崩溃了。我用谷歌搜索了它，但找不到答案。有任何想法吗？

谢谢！

可能是一个错误，设置android.minapi = 13或更大。
