Convert Android Java String[] array to C++ vector<string>

[Kyeiv]

I have a snippet like this:

//Java
static String[] stringArray(String s1, String s2) { ... }

//C++
QAndroidJniObject stringArray = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/TestClass",
                                                                          "stringArray"
                                                                          "(Ljava/lang/String;Ljava/lang/String;)[Ljava/lang/String;"
                                                                           string1.object<jstring>(),
                                                                           string2.object<jstring>());

Having stringArray how to convert it to vector<string>?

Having stringArray how to convert it to vector<string>?

You can do it like this:

QAndroidJniEnvironment jniEnv;
QStringList stringList;

if(stringArray.isValid())
{
    const jobjectArray stringListObjArray = stringArray.object<jobjectArray>();
    const int arraySize= jniEnv->GetArrayLength(stringListObjArray );
    
    for(int idx = 0; idx < arraySize; ++idx)
    {
        const QAndroidJniObject stringObj = QAndroidJniObject::fromLocalRef(jniEnv->GetObjectArrayElement(stringListObjArray , idx));
        stringList << stringObj .toString();
    }
}
