my code is here:

void Widget::on_auto_location_clicked()
{
    if(this->location_set_sys == 0)
        this->location_set_sys = 1;
    else if(this->location_set_sys == 1)
        this->location_set_sys = 0;

    QLocationPermission locationPermission;
    locationPermission.setAccuracy(QLocationPermission::Precise);
    if(qApp->checkPermission(locationPermission) != Qt::PermissionStatus::Granted) {
        qApp->requestPermission(QLocationPermission{}, this, &Widget::permissionUpdated);
    } else {
        qDebug() << "PERMISSION ALREADY GRANTED";
    }
    QGeoPositionInfoSource *source = QGeoPositionInfoSource::createSource("android",this);
    if (source) {
        // qDebug()<<"source";
        connect(source, &QGeoPositionInfoSource::positionUpdated,this,[=](const QGeoPositionInfo &info)
                {
                    qDebug()<<info;
                    ui->longitude->setText(QString::number(info.coordinate().longitude()));
                    ui->latitude->setText(QString::number(info.coordinate().latitude()));
                    QJsonObject message,params,location_set;
                    location_set.insert("location_set_sys",this->location_set_sys);
                    location_set.insert("longitude",info.coordinate().longitude());
                    location_set.insert("latitude",info.coordinate().latitude());
                    params.insert("aqi_out_of_door", "");
                    params.insert("aqi_in_the_room", "");
                    params.insert("win_state",this->win_state);
                    params.insert("humidity",0);
                    params.insert("temperature",0);
                    params.insert("openning_time",-1);
                    params.insert("aqi_threshold","");
                    params.insert("location_set",QString(QJsonDocument(location_set).toJson(QJsonDocument::Compact)));
                    message.insert("params",params);
                    message.insert("version","1.0.0");
                    mqtt_w->send_message(QString(QJsonDocument(message).toJson()));
                    qDebug()<<"info";
                    source->stopUpdates();
                });
        source->requestUpdate();
    }
    else
    {
        qDebug()<<"defeat";
    }
    // ui->auto_location->setEnabled(false);
}

if works well on linux mint,and two months ago it works on Android normally,too.
today when i test it again on Android ,it just return blank. the slot to get position never works after "source->requestUpdate();" <Q_Q<

here is the log:

D libai_win_arm64-v8a.so: PERMISSION ALREADY GRANTED
I qt.positioning.android: Unknown positioningMethod
I qt.positioning.android: Unknown positioningMethod
D qt.positioning.android: Single update using GPS
D qt.positioning.android: Looper Thread startup time in ms: 0
D qt.positioning.android: Single update using network
D qt.positioning.android: Stopping updates

yes ,everything looks normally,but,the slot do not works
help me !! <Q_Q<
