调用 Rust

我们现在可以从一个 C 二进制文件中调用它：

interoperability/rust/libanalyze/analyze.h

#ifndef ANALYZE_H
#define ANALYZE_H

void analyze_numbers(int x, int y);

#endif

interoperability/rust/analyze/main.c

#include "analyze.h"

int main() {
  analyze_numbers(10, 20);
  analyze_numbers(123, 123);
  return 0;
}

interoperability/rust/analyze/Android.bp

cc_binary {
    name: "analyze_numbers",
    srcs: ["main.c"],
    static_libs: ["libanalyze_ffi"],
}

在你的设备上构建，推送，并运行二进制文件 ：

m analyze_numbers
adb push "$ANDROID_PRODUCT_OUT/system/bin/analyze_numbers" /data/local/tmp
adb shell /data/local/tmp/analyze_numbers
