However, I found no "libflashdrop.so" in target\aarch64-linux-android\debug.

When I tried to execute commnad cargo ndk -t arm64-v8a -o . build, it failed again.

So wired........

My cargo.toml as follow:

[package]
name = "flashdrop"
version = "0.1.0"
edition = "2021"
crate-type = ["cdylib"]

[lib]
crate-type = ["cdylib"]

[dependencies]
jni = "0.21.1"
json = "0.12.4"

I don't have this issue when building libraries myself. Does your project have a lib.rs?

[ScSofts]

yes，and windows target can be built successfully

[bbqsrc]

Frustrating. I'm still investigating why. Only happens in some projects. <_<

[bbqsrc]

Hey @ScSofts, try version 3.1.1.

[ScSofts]

OK👌I'll have a try

[ScSofts]

It works smoothly! Good job!
