I created a ble library in Rust and try to integrate with android app makes crash always. Unable to load JNI modules. Is it really possible using Rust Ble module with android and ios app??
What is the exact crash message?

My question is is it a good idea that Rust ble library to be integrated with Android and IOS app. My thought is presently we write ble code in kotlin for android and in swift for IOS. Instead of writing same logic in two different platforms, I thought I can write ble logic in Rust and can be integrated with Android and iOS to show productivity. But at each step, integration is not even successful for simple add function which written in Rust and integrated with Android app.please recommended.
An unwrap somewhere in your code is failing. The panic message should be a bit earlier in the logs.
