折腾：
【未解决】Mac中用adb install安装安卓apk卡死
期间，改为：
adbInstallCmd = "adb -s {0} install -r {1}".format(self.device, item[3])
logging.info("Run cmd: %s", adbInstallCmd)
os.system(adbInstallCmd)输出信息，结果：
[201202 13:36:05][DevicesMethods.py 4065] Run cmd: adb -s hmucaei75ptk7szs install -r /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/task/20201202_fengyun_0192LeiMoChuanShuo/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
难道是路径太长？也不像啊
adb -s hmucaei75ptk7szs install -r /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/task/20201202_fengyun_0192LeiMoChuanShuo/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
此处有244了，或许快要超过255，或许255是最大限制？
那手动去iTerm2中运行，且缩短路径试试
~/Downloads/pre_download adb install 20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk Performing Streamed Install
结果：就可以正常安装。。。
好像还真的是路径太长导致的？
那去试试，改写代码，把此处要安装的apk，每次复制一份到别处，比如download目录
期间涉及到：
创建临时文件和文件夹
拷贝文件
python temp folder
python copy file
How do I copy a file in Python? – Stack Overflow
其中：
创建临时文件夹：
tmpFolder = tempfile.TemporaryDirectory()
logging.info("tmpFolder=%s", tmpFolder)
# tmpFolder=<TemporaryDirectory '/var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmp_yk15rlz'>
tmpFolderName = tmpFolder.name
logging.info("tmpFolderName=%s", tmpFolderName)
# tmpFolderName=/var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmp_yk15rlz拷贝文件：
方式1：
apkFileName = os.path.basename(apkFilePath)
logging.info("apkFileName=%s", apkFileName)
# apkFileName=20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
tmpApkFile = os.path.join(tmpFolderName, apkFileName)
logging.info("tmpApkFile=%s", tmpApkFile)
# tmpApkFile=/var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmp_yk15rlz/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
logging.info("Copy %s to tmp file %s", apkFilePath, tmpApkFile)
# Copy /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/task/20201202_fengyun_0192LeiMoChuanShuo/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk to tmp file /var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmp_yk15rlz/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
copyfile(apkFilePath, tmpApkFile)方式2：
无需计算src的文件全路径中的basename即filename，直接dst用目录即可：
copy2(apkFilePath, tmpFolderName)
最后完整代码：
logging.info("start to install app in {}".format(os.path.basename(self.arg_options.task)))
apkFilePath = item[3]
# os.system("adb -s {0} install {1}".format(self.device, apkFilePath))
adbInstallCmd = "adb -s {0} install -r {1}".format(self.device, apkFilePath)
# length=243 command:

# sometime will stuck, reason: maybe command length too large, > 255?
# so copy to temp folder -> to reduce command string length
tmpFolder = tempfile.TemporaryDirectory()
logging.info("tmpFolder=%s", tmpFolder)
# tmpFolder=<TemporaryDirectory '/var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmp_yk15rlz'>

最终得以正常的
adb install xxx.apk
了。
此处，是Python通过os.system调用
adb -s hmucaei75ptk7szs install -r /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/task/20201202_fengyun_0192LeiMoChuanShuo/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
感觉是：由于命令太长，（接近）超过了255的限制？导致无法正常执行
解决办法：把命令长度改短
此处去把apk文件放到一个路径更短的地方
比如，临时文件夹
adb -s hmucaei75ptk7szs install -r /var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmpq3ypjfgd/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
其长度只有153，没（接近）超过255
即可正常的安装apk到安卓手机中了
注：此办法，暂时适合此apk，对于其他apk是否适用，有待以后长期的验证才能知道结果。
后来发现，问题依旧：
别的apk，即使是短路径：
Run length=154, command: adb -s hmucaei75ptk7szs install -r /var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmpzylriew2/20201202_fengyun_0185BingFengTianXia_gameApp_Android_0.apk
也还是会卡死。
看来不是路径问题。。。
【总结】
此处，至少感觉是
通过把adb总体命令长度减少
从：
adb -s hmucaei75ptk7szs install -r /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/task/20201202_fengyun_0192LeiMoChuanShuo/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
长度：超过240多，感觉快要接近255的限制？了
而减少命令长度：
adb -s hmucaei75ptk7szs install -r /var/folders/gt/5868sbcd1jq4rxvryqhy2_1sz8n0s3/T/tmpq3ypjfgd/20201202_fengyun_0192LeiMoChuanShuo_gameApp_Android_0.apk
长度：150多，不会超过限制？
从而：
当时是解决了问题。
后续感觉，至少是缓解了adb install apk卡死的问题
但是，后续长期运行发现：还是没彻底解决问题。
所以根本原因不是此处命令长度的问题。根本原因暂时未知。
