可能有三个情况，1.adb没装，2.没配置adb路径，3.os.system()调用adb失败，返回值是32512，代码中所有adb改成adb所在的路径

FileNotFoundError: [Errno 2] No such file or directory: './1.png' 怎么解决？ adb是可以找到设备的，而且adb安装路径也加入到系统路径里了

一、Ubuntu环境

建立或修改文件 ~/.android/adb_usb.ini，在文件开头或末尾添加一行，内容是0x2a45。
建立或修改文件 /etc/udev/rules.d/51-android.rules
2.1 修改文件权限：
sudo chmod a+rx /etc/udev/rules.d/51-android.rules

2.2 在文件中添加一行内容：
SUBSYSTEM=="usb", ATTR{idVendor}=="2a45", MODE="0666", GROUP="plugdev"

确保你在用户组"plugdev"
sudo adduser plugdev
按下面流程重启udev服务或直接重启PC
sudo service udev restart
检查ADB设备是否存在
adb kill-server
adb devices

二、Windows XP中文环境

建立或修改C:\Documents and Settings<你的用户名>.android\adb_usb.ini文件，在该文件中添加一行文本，内容是0x2a45。
检查ADB设备是否找到（命令行程序中）
adb kill-server
adb devices
　　
三、Windows 7中文环境
建立或修改C:\用户<你的用户名>.android\adb_usb.ini文件，在该文件中添加一行文本，内容是0x2a45。
检查ADB设备是否找到（命令行程序中）
adb kill-server
adb devices

参考文档： http://developer.android.com/tools/device.html

ps:本人魅族pro6plus ，内置光盘里有个这个adb连接的说明文件，我在C盘对应目录创建了这个adb_usb.ini文件，重启adb服务就好了

Wenhao-Xu · 2017-12-31T08:49:34Z

在设置系统路径后应该就能执行adb了

cq674350529 · 2017-12-31T12:21:27Z

首先感谢各位的工作。
安装新版本后貌似还是存在问题(暂时未进行调试查明原因)，获取图片采用原来的方式貌似可以。
错误信息如下：

获取图片的方式如下：

def pull_screenshot():
    flag = os.system('adb shell /system/bin/screencap -p /mnt/sdcard/autojump.png')
    os.system('adb pull /mnt/sdcard/autojump.png .')

daxing100 · 2017-12-31T12:31:12Z

截图部分改成下面代码可以顺利运行，亲测
def pull_screenshot():

if flag == 1:
print('请安装ADB并配置环境变量')
# sys.exit()
os.system('adb pull /mnt/sdcard/autojump.png .')

F-loat · 2017-12-31T12:33:00Z

电脑操作系统是什么，代码是加了平台判断之后的吗，linux的我暂时不太方便测试

daxing100 · 2017-12-31T12:37:16Z

@F-loat 我用的是Mac

F-loat · 2017-12-31T12:40:34Z

mac就更不方便了😂，你们试着调试下，也可能是执行shell命令的那个函数的参数需要修改，这种方式省去了把图片储存在手机上的过程，可以避免不同机型文件路径的差异导致无法获取截图

F-loat · 2017-12-31T12:43:03Z

类unix系统和windows系统的换行符不一样，之前有人说去掉替换换行符的步骤mac就可以用了，代码也相应做过修改了，但是我没法测试

lvusyy · 2017-12-31T13:10:32Z

@F-loat 用 os.sep,python会自动适应的.

cq674350529 · 2017-12-31T13:25:32Z

@F-loat 在windows上我进行了调试，需要将pull_screenshot()修改为如下内容：

if sys.platform == 'win32':
    screenshot = screenshot.replace(b'\r\r\n', b'\n')

F-loat · 2017-12-31T13:33:39Z

KiritoStudio · 2017-12-31T16:41:14Z

@F-loat @wangshub 经过调试，发现mac下也需要使用\n代替\r\n，需要加入一串判断的代码：

@KiritoStudio 嗯，这个已经在测试兼容性了，#325，有了结论后会进行更新

boyrabbit233 · 2018-01-01T01:53:39Z

win7 64，安卓手机，修改一下main()函数代码就可以用了，不过首先得把adb的系统路径加一下，手动测试两条命令是否能执行。
.....
#pull_screenshot()
os.system('adb shell screencap -p /mnt/sdcard/djump.png')
os.system('adb pull /mnt/sdcard/djump.png')

msterzhang · 2018-01-01T01:53:59Z

def pull_screenshot():
os.system('adb shell screencap -p /sdcard/autojump.png')
os.system('adb pull /sdcard/autojump.png .')
# process = subprocess.Popen('adb shell screencap -p', shell=True, stdout=subprocess.PIPE)
# screenshot = process.stdout.read()
# if sys.platform == 'win32':
# screenshot = screenshot.replace(b'\r\n', b'\n')
# f = open('autojump.png', 'wb')
# f.write(screenshot)
# f.close()
成功运行

RichardWeiYang · 2018-01-01T02:10:13Z

current master branch (commit 909edf4) wechat_jump_auto.py can't work on my windows system.

The reason is the pull_screenshot() function can't retrieve screenshot.

def pull_screenshot():
    process = subprocess.Popen('adb shell screencap -p', shell=True, stdout=subprocess.PIPE)
    screenshot = process.stdout.read()
    if sys.platform == 'win32':
        screenshot = screenshot.replace(b'\r\n', b'\n')
    f = open('autojump.png', 'wb')
    f.write(screenshot)
    f.close()

Then I replace this implementation with the old version:

    os.system('adb shell screencap -p /sdcard/autojump.png')
    os.system('adb pull /sdcard/autojump.png .')

This works fine.

I am not familiar with the python process, so not sure how to fix it.

我也遇到了IOError: cannot identify image file './autojump.png'
我估计问题是出在

if sys.platform == 'win32':
        screenshot = screenshot.replace(b'\r\n', b'\n')

这个地方。我查看图片的十六进制的时候，发现正常截图（通过adb pull）和使用代码截图出来的时候，会看到很多中间会多出来很多00 00的编码。其他地方都一样

更新：
解决了。把代码稍微改一下：

if sys.platform == 'win32':
        screenshot = screenshot.replace(b'\r\r\n', b'\n')

查看了下，他是用的\r\r\n分割，代码原始部分只有\r\n，所以还剩下了一个\r。加上去就完美运行了。

最新版本的已经可以用了，分别测试了华为的三个型号的手机，分别是华为荣耀5C、华为mate9、华为麦芒5，后两者可以运行，大部分落在中心点上；5C的分数进展慢一些，大部分都不在中心点上。
win10 64位+python 3.6.2， adb是根据readme中指示下的
用的默认config：
{
"under_game_score_y": 300,
"press_coefficient": 1.392,
"piece_base_height_1_2": 20,
"piece_body_width": 70
}

问题解决是default.json 放在config文件夹下，config文件夹和py文件放在一个文件夹中
