Android应用程序立即关闭。用buildozer p4a编译
提问于 2020-12-22 01:16:50
我正在为2轮机器人编写一个应用程序，通过UDP进行通信。在PC上，一切都很好，但是在通过buildozer为android编译之后，一切都不起作用。
这是logcat寄来的

我怀疑这个问题是由于时间的问题。Android设备可能比您的PC稍慢一些，导致在调用ids时GUI实例中的WHJoy()还没有准备好。我建议从Clock.schedule_interval()方法中删除__init__()调用，并延迟一些间隔调用的开始。可能是从on_start()的App方法开始的。
class GUIApp(App):
def build(self):
return GUI()
def on_start(self):
Clock.schedule_interval(self.root.update, 1/30.0)
Clock.schedule_interval(self.root.change_color, 1 / 1)作为一种测试，为了看看时间是否是罪魁祸首，请尝试运行以下命令：
class GUIApp(App):
def build(self):
Clock.schedule_once(self.start_intervals, 3)
return GUI()
def start_intervals(self, dt):
Clock.schedule_interval(self.root.update, 1/30.0)
Clock.schedule_interval(self.root.change_color, 1 / 1)这段代码在启动间隔(3秒)之前会造成极大的延迟。当然，对于最终的代码来说，这是不可接受的，但是如果这消除了错误，那么计时就是问题了。
