Question

我用kivy写了一个简单的应用程序。它在我的桌面上运行得很好，但我希望它能在Android上运行。但是，当我将它安装到我的Android手机上时，它会在启动时崩溃。

应用程序在局域网上播放，等待回复。然后，任何回复的人都会被添加到列表中并显示在屏幕上。

这是我的代码：

import kivy
import random
import socket
import threading

kivy.require('1.7.2')  # replace with your current kivy version !

from kivy.app import App
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.properties import ObjectProperty
from kivy.uix.button import Button
from kivy.uix.gridlayout import GridLayout
from functools import partial

from multiprocessing import Process, Queue
from time import sleep
import socket
import random

CHECK_MESSAGE = "Who is alive?"


class Communicator:

    def requester(self):
        address = ('<broadcast>', 54545)

        client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        client_socket.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)

        string_list =[]

        while True:
            #print "broadcasting done by " + self.my_name
            client_socket.sendto(CHECK_MESSAGE, address)
            recv_data, addr = client_socket.recvfrom(2048)

            if self.my_name == recv_data or recv_data in string_list:
                sleep(3)
                continue

            string_list.append(recv_data)
            self.callback(string_list)
            sleep(3)

    def replyer(self):
        address = ('', 54545)
        server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)
        server_socket.bind(address)
        #print my_name

        while True:
            #print "Listening"
            recv_data, addr = server_socket.recvfrom(2048)
            if recv_data == CHECK_MESSAGE:
                server_socket.sendto(self.my_name, addr)

    def __init__(self, callback_function):
        self.callback = callback_function
        self.my_name = socket.gethostname() + ' ' + str(int(random.random()*10000))

    def start_all(self):
        self.start_server()
        self.start_client()

    def start_client(self):
        client = threading.Thread(target=self.requester)
        client.daemon = True
        client.start()

    def start_server(self):
        server = threading.Thread(target=self.replyer)
        server.daemon = True
        server.start()

class Client:

        grid = self.grid_l
        grid.bind(minimum_height=grid.setter('height'),
                  minimum_width=grid.setter('width'))

        x = random.randint(2, 5)

        #if self.list_of_peers is not None:

        self.grid_l.clear_widgets()

        self.list_of_peers = GridLayout(cols=1, row_default_height=40,

        new_text = result
        self.top_lbl.text = new_text

    def btn2_pressed(self, *args):
        self.grid_l.clear_widgets()
        #pass


class PongApp(App):

    def build(self):

        my_app = Pong()
        queue = Queue()

        my_app.queue = queue
        Communicator(my_app.search_btn_pressed).start_all()

        return my_app

if __name__ == '__main__':
    App = PongApp().run()

和pong.kv：

#:kivy 1.7.2

<Pong>:
    scroll_view: scrollviewID
    top_lbl: lblID
    grid_l: gridlayoutID
    AnchorLayout:
        size_hint: 1, .1
        pos_hint: {'x': 0, 'y': .9}
        anchor_x: 'center'
        anchor_y: 'center'
        Label:
            id: lblID
            text: 'This is the app..'
    Button:
        size_hint: 1, .1
        pos_hint: {'x': 0, 'y': .8}
        text: 'Refresh?'
        #on_release: root.search_btn_pressed()

    ScrollView:
        id: scrollviewID
        orientation: 'vertical'
        pos_hint: {'x': 0, 'y': 0}
        size_hint: 1, .8
        bar_width: '8dp'
        GridLayout:
            id: gridlayoutID
            cols: 1
            size_hint: 1, None
            row_default_height: 40
            row_force_default: False

我跑了“./distribute.sh -m”openssl pil kivy“” 然后 “./build.py --dir~ / Desktop / MyProject / --package org.test.florin --name “ShareAll”--version 0.0.1 - 允许INTERNET调试安装“

这会将应用程序发送到我的手机，但是当我启动它时，它会崩溃。我错过了什么吗？不知道如何得到任何错误..

这是我第一次使用kivy（或Android）

这是adb logcat http://pastebin.com/embed_js.php?i=28KaFM79

不知道为什么会那么大..

Answer 1

I / python（16193）：找不到main.pyo / main.py。

这是您文件中的错误（您可以通过点击python或使用adb自己的语法来查看与kivy相关的行。）

所以...是你的主文件main.py？如果是这样的话，它不会因某种原因被包括在内。
