NDK 获取android的imei和serial number

1，获取imei

int setAndroidDeviceID(JNIEnv *env, jobject obj,jobject mContext)
{if(mContext == 0){return -1;}jclass cls_context = (*env)->FindClass(env, "android/content/Context");if(cls_context == 0){return -1;}jmethodID getSystemService = (*env)->GetMethodID(env, cls_context, "getSystemService", "(Ljava/lang/String;)Ljava/lang/Object;");if(getSystemService == 0){return -1;}jfieldID TELEPHONY_SERVICE = (*env)->GetStaticFieldID(env, cls_context, "TELEPHONY_SERVICE", "Ljava/lang/String;");if(TELEPHONY_SERVICE == 0){return -1;}jstring str = (*env)->GetStaticObjectField(env, cls_context, TELEPHONY_SERVICE);jobject telephonymanager = (*env)->CallObjectMethod(env, mContext, getSystemService, str);if(telephonymanager == 0){return -1;}jclass cls_tm = (*env)->FindClass(env, "android/telephony/TelephonyManager");if(cls_tm == 0){return -1;}jmethodID getDeviceId = (*env)->GetMethodID(env, cls_tm, "getDeviceId", "()Ljava/lang/String;");if(getDeviceId == 0){return -1;}jstring deviceid = (*env)->CallObjectMethod(env, telephonymanager, getDeviceId);DP_IMIE = (*env)->GetStringUTFChars(env, deviceid, 0);return 0;
}

　　2，获取serial number

#include <sys/system_properties.h>
void getAndroidDeviceID_Serial(char *deviceID)//serial number
{__system_property_get("ro.serialno",deviceID);
}
