Android minSDK requirement

[michaelWuensch]

I just tested a NWC connection on different API levels on Android Studio Emulator. Every version before API Level 30 crashed. 30 and Above worked.

This suggests the minSDK requirement is API 30 (Android 11), but I could not find that requirement anywhere documented.

Therefore my questions:
Is this known and on purpose?
Is there any way to make it work on API Levels below 30?

For info, the error looks like this:
Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x2d8336 in tid 3607 (bitbanana.debug), pid 3607 (bitbanana.debug)

Could it depends by the version of NDK that I use for compiling the Android bindings? I'm currently using the v26.1

In the build.gradle.kt I've set the minSDK to 21, because I was unsure about the right version (on my machine I'm not able to run the Android Studio Emulator, so test older APIs). I see other similar projects like bdk-ffi and Breez, have set the minSDK to 24.

I just noticed that I can specify the API level when compiling with NDK. I'm going to try to compile it again and ship a new SNAPSHOT.

I've recompiled setting the API level to 21 and published a SNAPSHOT (0.43.0-SNAPSHOT). Let me know if it works

@yukibtc as it is the same dependency name I made sure it is redownloaded, but still crashing on API 29 while it works on API 30.

I never made a rust library, so I unfortunately can't help you.

For my app this is not urgent at all, I just wanted to let you know. My userbase has very new phones and for all other I can make a simple version check and tell them that they need at least Android 11 for the NWC feature instead of letting the app crash.

But maybe others would like a lower minSDK requirement.

@michaelWuensch, this is fixed at commit 6ecd3ba

I've released org.rust-nostr:nostr-sdk:0.44.1
