如何在Android应用程序(APK)运行时从内存中获取基地址？

public class NativeUtils {
    static {
        System.loadLibrary("native-lib");
    }

    public static native long getBaseAddress();
}

#include <jni.h>
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

JNIEXPORT jlong JNICALL Java_com_example_NativeUtils_getBaseAddress(JNIEnv *env, jclass clazz) {
    FILE *fp = fopen("/proc/self/maps", "r");
    if (fp == NULL) {
        return 0;
    }

    char line[256];
    while (fgets(line, sizeof(line), fp)) {
        if (strstr(line, "/data/app/com.example.myapp")) { // 替换为你的应用包名
            char *token = strtok(line, "-");
            if (token != NULL) {
                fclose(fp);
                return strtoul(token, NULL, 16);
            }
        }
    }

    fclose(fp);
    return 0;
}

long baseAddress = NativeUtils.getBaseAddress();
System.out.println("Base Address: 0x" + Long.toHexString(baseAddress));
