Submit argument(s) to a program restart on Android

[SeDi]

Hi,
I need to be able to restart my App. On the Android platform I do this as proposed here by Bogdan. It works flawlessly.

Unfortunately I don't have the slightest idea, how (or even if) I can provide arguments to my pendingIntent. I have (naively) tried:

QAndroidJniObject arg = QAndroidJniObject::fromString("Camera");
alarmManager.callMethod<void>("set",
                              "(IJLandroid/app/PendingIntent;)V",
                              QAndroidJniObject::getStaticField<jint>("android/app/AlarmManager", "RTC"),
                              jlong(QDateTime::currentMSecsSinceEpoch() + 500), pendingIntent.object(), arg.object());

But it didn't show up as an argument in my app. On Windows,

QProcess::startDetached(programName, arguments);

does that trick, but I don't know how to provide the information here.

Any idea - including a tipp on where to read about this stuff - is highly appreciated.
I have tried to understand the man pages of PendingIntent and AlarmManager, but I don't see what I am looking for.

Here's what I do so far:

int main(int argc, char *argv[])
{
     ///... (shortened)
    QStringList arguments;
    if (currentExitCode == Controller::EXIT_CODE_REBOOT_TO_CAMERA) {
         arguments<<"Camera";
    }
    if (currentExitCode == Controller::EXIT_CODE_REBOOT || currentExitCode == Controller::EXIT_CODE_REBOOT_TO_CAMERA) {
        ///... (shortened)
        #ifdef Q_OS_ANDROID
            auto activity = QtAndroid::androidActivity();
            auto packageManager = activity.callObjectMethod("getPackageManager",
                                                            "()Landroid/content/pm/PackageManager;");

            auto activityIntent = packageManager.callObjectMethod("getLaunchIntentForPackage",
                                                                  "(Ljava/lang/String;)Landroid/content/Intent;",
                                                                  activity.callObjectMethod("getPackageName",
                                                                  "()Ljava/lang/String;").object());

            auto pendingIntent = QAndroidJniObject::callStaticObjectMethod("android/app/PendingIntent", "getActivity",
                                                                           "(Landroid/content/Context;ILandroid/content/Intent;I)Landroid/app/PendingIntent;",
                                                                           activity.object(), jint(0), activityIntent.object(),
                                                                           QAndroidJniObject::getStaticField<jint>("android/content/Intent",
                                                                                                                   "FLAG_ACTIVITY_CLEAR_TOP"));
            auto alarmManager = activity.callObjectMethod("getSystemService",
                                                          "(Ljava/lang/String;)Ljava/lang/Object;",
                                                          QAndroidJniObject::getStaticObjectField("android/content/Context",
                                                                                                  "ALARM_SERVICE",
                                                                                                  "Ljava/lang/String;").object());

            alarmManager.callMethod<void>("set",
                                          "(IJLandroid/app/PendingIntent;)V",
                                          QAndroidJniObject::getStaticField<jint>("android/app/AlarmManager", "RTC"),
                                          jlong(QDateTime::currentMSecsSinceEpoch() + 500), pendingIntent.object());

        #endif

    }
    qApp->quit();
    app->deleteLater();

    return currentExitCode;
}
