Resolve Android crashes and improve reliability

[batchar2]

Hi! Thanks a lot for this great library! I'm using it in my project.

Unfortunately, I encountered a few issues on Android related to networking and locking, so I tried to address them:

• Replaced deprecated gethostbyname with getaddrinfo
• Improved network error handling
• General code cleanup and refactoring

Let me know if anything needs to be changed!
