Qt中擷取Android手機的IMEI。

#include <QString>

#include <QAndroidJniEnvironment>

#include <QandroidJniObject>

QString getDeviceImei(){  

QAndroidJniEnvironment env;  

jclass contextClass = env->FindClass("android/content/Context");  

jfieldID fieldId = env->GetStaticFieldID(contextClass, "TELEPHONY_SERVICE", "Ljava/lang/String;");

QAndroidJniObject qtActivityObj = 

QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");   jobject telephonyManager = env->CallObjectMethod(qtActivityObj.object<jobject>(), methodId, telephonyManagerType);  

methodId = env->GetMethodID(telephonyManagerClass, "getDeviceId", "()Ljava/lang/String;");

QString imei(buf_devid);  

delete buf_devid;  

return imei;
