This is related to Google Play and OpenSSL warning message. Play store recommend to use the following command to grep:
$ unzip -p YourApp.apk | strings | grep "OpenSSL"
But on Windows, this command is not running. However I have installed WinZip, WinRAR, Cygwin and MinGW. So please help me to run this command so I can come to know the issue where it is ?
