good job!

Missing import: import javax.net.ssl.HostnameVerifier

for me still not working. Showing same error again and again. Please help me out.

@vishavgoria added, thanks for letting me know.

@RavinCristiano May you share some logs? It's been a while since a last used this approach, I'm not sure it still works.

If anyone is wondering out there, it still works!
I've just updated it with suppress warnings and updated syntax.

how to use in react native?

how to use in react native?

You have to create a module/plugin(not sure how it's called) containing it.
I'd like to emphasize that it's just for testing purposes, do not use it on production. If your Https is not verified it can potentially open up doors for suspicious things. Be careful.
