我正在尝试构建 flutter_rust_bridge project (frb_example/with_flutter) 适用于 Android，但在尝试运行时多次收到以下错误:

提到的 libflutter_rust_bridge_example.so 文件应该在哪里？
我还收到以下警告:

Android 模拟器 (Nexus 5 android-x86) 如下所示:
正如您所看到的，应该由 Rust 生成的图像丢失了。如果我为 Windows 构建一切都很好:
操作系统:Windows 10
Flutter版本:Flutter 3.0.0
使用rust 版本:1.60.0
启动模拟器的IDE:Vs Code
用于创建模拟器的IDE:Android Studio
最佳答案
我在我的 Arch Linux KDE 笔记本电脑上遇到了同样的问题。 对我来说，这是由于忘记运行所需的上一步而引起的(请参阅 tutorial description ):
cd ~/Development/git/flutter_rust_bridge/frb_example/with_flutter/rust
cargo ndk -o ../android/app/src/main/jniLibs build
之后，由于缺少依赖项，该步骤失败，在我的情况下，通过安装修复了该问题:
cargo install cargo-ndk
rustup target add armv7-linux-androideabi
rustup target add aarch64-linux-android
(所需的目标架构取决于所使用的手机型号/模拟器)
如果仍然无法解决问题，也许可以尝试将存储库重置为新克隆的状态:
cd ~/Development/git/flutter_rust_bridge
git clean -d -x -f
