本文介绍了两种在Android设备上获取设备标识的方法：一种是通过TelephonyManager获取IMEI，另一种是通过系统属性获取Serial Number。这两种方法对于实现设备唯一标识的应用场景非常有用。

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);
}
