Get data in customActivity from Qt

[Alioune]

Hi all
I am new to QtAndroidExtra. I used the example of the QtCreator IDE "CustomActivity" and wanted to know if it is possible to get data in android custom activity from Qt for example
Qstring myVar = "Hello World" and retrieve it in CustomActivity.java after its start
String recvVar = myVar
to use it in a method of the class

My question is I want to send data and retrieve it in java. for exeomple

void ActivityHandler::activityReceiver(int requestCode, int resultCode, const QAndroidJniObject &data)
{
if (requestCode == REQUEST_CODE) {
if (resultCode == RESULT_OK) {

        const QAndroidJniObject key = QAndroidJniObject::fromString("message");

        const QAndroidJniObject message = data.callObjectMethod(
                "getData", "(Ljava/lang/String;)Ljava/lang/String;", key.object());

        if (message.isValid())
            emit ActivityHandler::instance()->receiveFromActivityResult(message.toString());
    } else {
        emit ActivityHandler::instance()->receiveFromActivityResult("Rejected!");
    }
}

}
