C++获取安卓设备的IMEI和Mac地址

获取安卓设备的IMEI和Mac地址需要使用安卓系统的API，可以使用C++调用Java代码来实现。

获取IMEI的代码示例：

#include <jni.h>
#include <string>

extern "C" JNIEXPORT jstring JNICALL
Java_com_example_androidimei_MainActivity_getIMEI(JNIEnv *env, jobject /* this */) {
    jclass contextClass = env->FindClass("android/content/Context");
    jfieldID fieldID = env->GetStaticFieldID(contextClass, "TELEPHONY_SERVICE", "Ljava/lang/String;");
    jstring jstr = (jstring)env->GetStaticObjectField(contextClass, fieldID);
    const char* str = env->GetStringUTFChars(jstr, NULL);

    jclass telephonyManagerClass = env->FindClass("android/telephony/TelephonyManager");
    jmethodID getSystemServiceID = env->GetMethodID(contextClass, "getSystemService", "(Ljava/lang/String;)Ljava/lang/Object;");
    jobject telephonyManager = env->CallObjectMethod(thisObj, getSystemServiceID, env->NewStringUTF(str));
    jmethodID getDeviceIDID = env->GetMethodID(telephonyManagerClass, "getDeviceId", "()Ljava/lang/String;");
    jstring imei = (jstring)env->CallObjectMethod(telephonyManager, getDeviceIDID);

    env->ReleaseStringUTFChars(jstr, str);

    return imei;
}

获取Mac地址的代码示例：

#include <jni.h>
#include <string>

extern "C" JNIEXPORT jstring JNICALL
Java_com_example_androidimei_MainActivity_getMacAddress(JNIEnv *env, jobject /* this */) {
    jclass contextClass = env->FindClass("android/content/Context");
    jfieldID fieldID = env->GetStaticFieldID(contextClass, "WIFI_SERVICE", "Ljava/lang/String;");
    jstring jstr = (jstring)env->GetStaticObjectField(contextClass, fieldID);
    const char* str = env->GetStringUTFChars(jstr, NULL);

    jclass wifiManagerClass = env->FindClass("android/net/wifi/WifiManager");
    jmethodID getSystemServiceID = env->GetMethodID(contextClass, "getSystemService", "(Ljava/lang/String;)Ljava/lang/Object;");
    jobject wifiManager = env->CallObjectMethod(thisObj, getSystemServiceID, env->NewStringUTF(str));
    jmethodID getConnectionInfoID = env->GetMethodID(wifiManagerClass, "getConnectionInfo", "()Landroid/net/wifi/WifiInfo;");
    jobject wifiInfo = env->CallObjectMethod(wifiManager, getConnectionInfoID);
    jmethodID getMacAddressID = env->GetMethodID(wifiInfoClass, "getMacAddress", "()Ljava/lang/String;");
    jstring macAddress = (jstring)env->CallObjectMethod(wifiInfo, getMacAddressID);

    env->ReleaseStringUTFChars(jstr, str);

    return macAddress;
}

注意：上述代码中的`Java_com_example_androidimei_MainActivity_getIMEI`和`Java_com_example_androidimei_MainActivity_getMacAddress`是Java代码的方法名，需要替换成你自己的方法名。此外，还需要在AndroidManifest.xml中添加对应的权限，例如获取IMEI需要添加`<uses-permission android:name="android.permission.READ_PHONE_STATE"/>`。
