[Bug] Android emulator, Session crashes on open

[ao-swarm]

Describe the bug

Opening a Zenoh Session on an Android emulator always results in an application crash. Blocks Android emulator use. I've provided a sample project to reproduce this.

To reproduce

1. Start emulator.
2. Open app that starts a Zenoh Session.
3. Watch it crash. 😃

Sample project that reproduces every time: https://github.com/ao-swarm/Zenoh-Emulator-Crash

System info

• Platform: Android Emulator, Pixel 5, API 30, x86
• Zenoh: 1.0.0 release

Hi, I finally took some time to look into this issue. Unfortunately I haven't been able to reproduce it on arm64 based emulators (couldn't run x86 emulators because Qemu doesn't provide x86 emulation support on m2 chips from Macs).
Looking at the logs it seems that the key param provided to the session.declareKeyExpr function is not valid anymore from the native perspective (an error thrown by the Rust JNI lib we use). I wonder if it's related to the context switch at Kotlin level (because the function is called within a withContext(Dispatchers.IO) { ... } call).

Have you tried the using different emulator architectures and Android versions?
