Kivy应用程序刚刚加载，然后在android中关闭

我已经用bash和buildozer在windows上构建了我的应用程序，它成功地完成了，然后我把apk放在了我的android 7手机上，但它只是加载然后关闭，没有任何消息或任何东西。我怎样才能解决这个问题

放置一些断点并调试代码以检查发生了什么

这是我的代码，我不知道为什么我不能运行api

        self.cols = 1



        #Labels

        my_dict = {}
        for idx, val in enumerate(k): 
            my_dict["v{}".format(idx)] = str(val)

        self.Mac_address.text = "The MAC address is : "+':'.join(re.findall('..', '%012x' % uuid.getnode()))
        self.GPS.text = my_dict['v0'] + ',' +  my_dict['v1']
        self.time_stamp.text = "timestamp :"+ Time_now

class test_app(App):
    def build(self):
        return MainPage()



if __name__ == "__main__":
    test_app().run()

我这样做了，但事实上，你提供的信息还不足以挖掘@Ashrafkhaledh我们可以如何帮助你而没有任何线索？请阅读并向我们提供关于你的问题的更好的描述。尝试在你的手机连接到PC的情况下运行

buildozer android deploy运行logcat

。然后查看logcat输出。
