Openssl issue on Android

OpenSSL Dependency Issue in Dioxus Framework (Android Mobile Development)

I'm currently working on a project using Dioxus for mobile development targeting Android, but I'm running into an issue
when I try to build or run the project, I receive the following error:

The error is happening each time I am trying to use the reqwest crate in the app. Else the app works fine as long as reqwest is not used.

Like for example when I try to run the HotDog tutorial from the docs on Android, I also get that error.

So I tried to follow the instruction on the Dioxus documention for Android and added the necessary path variable on my computer but I still am getting that error. Does someone have an idea how to solve this issue?

P.S: this error does not happen on Dioxus web/desktop.

i got the same error turning off the default-features and using rustls-tls solved the issue.

reqwest = { version = "0.12.15", features = ["json", "rustls-tls"], default-features = false }

the official documentation says that only enabling the vendored features will fix the problem,I haven't tried it, give it a look.
