[SOLVED]QT 5.3 for Android in GPS mode don't work !!!

[projetoslinux]

Hi for all...

I have sucess in create JNI gps positioning, but want change to C++ positioning, testing new QT5.3
and modify for access and read simplelog.txt file in android, and add AndroidManifest to access sdcard and
positioning permissions to fine locations , but not return any coordinates !!!!

iam testing all positioning examples for 5.3.
in Development 5.3 is full for android GPS !!!

testing in Sansung note 3 octa , genesis tab 7326 dual, friendlyarm quad tiny 4412, and never sucess.

all devices is rooted....
and android > android 4.0
any idea...

thanks.

Hi
I have tried to test Weetherinfo sample and immediatly one didn't work rightly (I did not get information too). I have not time to investigate code of this sample moreover I am not strong enough in QML. But I exactly know positioning works correctly. I have my application written on pure C++. You may write your own application.
For this do next

• in .pro file add
  @QT += positioning@

• add slot
  @void positionUpdated(const QGeoPositionInfo &info);@
  in your class and

@ #include <QGeoPositionInfoSource> @

in header where this class places.

• in constuctor add

@....
QGeoPositionInfoSource *source = QGeoPositionInfoSource::createDefaultSource(0);

if (source) {

//here set up your update interval in msecs
source->setUpdateInterval(1000);// 1 second
connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)),
this, SLOT(positionUpdated(QGeoPositionInfo)));
source->startUpdates();
}
.....
@

• write your slot for example
  @
  void ControlDialog::positionUpdated(const QGeoPositionInfo &info)
  {QGeoCoordinate coord=info.coordinate();
  double lat,lng;
  lat = coord.latitude();
  lng = coord.longitude();
  if(info.isValid()){
  ////.......
  }
  else{
  /////.....
  }
  qDebug() << "Position updated:" << info;
  }
  @

If you want to get satellite information similarly do next

• add slots

@
void satellitesInViewUpdated( const QList<QGeoSatelliteInfo>& satellites );
void satellitesInUseUpdated( const QList<QGeoSatelliteInfo>& satellites );@

add header

@#include <QGeoSatelliteInfoSource>@

• add in constructor

@....
QGeoSatelliteInfoSource* satelliteInfoSource = QGeoSatelliteInfoSource::createDefaultSource( 0 );
if ( satelliteInfoSource ) {
satelliteInfoSource->setUpdateInterval(2000);
// Whenever the satellite info source signals that the number of
// satellites in use is updated, the satellitesInUseUpdated function
// is called
connect( satelliteInfoSource,SIGNAL( satellitesInUseUpdated(const QList<QGeoSatelliteInfo>& ) ),
this,SLOT( satellitesInUseUpdated(const QList<QGeoSatelliteInfo>& ) ) );

     // Whenever the satellite info source signals that the number of
     // satellites in view is updated, the satellitesInViewUpdated function
     // is called
     connect( satelliteInfoSource, SIGNAL( satellitesInViewUpdated(const QList<QGeoSatelliteInfo>& ) ),
                                      this, SLOT( satellitesInViewUpdated(const QList<QGeoSatelliteInfo>& ) ) );

     // Start listening for satellite updates
      satelliteInfoSource->startUpdates(); 
}

@

• write your satellite information slots
  @
  void ControlDialog::satellitesInViewUpdated(const QList<QGeoSatelliteInfo>& satellites )
  {
  // The number of satellites in view is updated
  ui->lbl_SatInView->setText(QString::number(satellites.size()));
  // mLastGPSInformation.satellitesInView.clear();
  // for ( int i = 0; i < satellites.size(); ++i ){
  // QGeoSatelliteInfo currentSatellite = satellites.at( i );
  // QgsSatelliteInfo satelliteInfo;
  // satelliteInfo.azimuth = currentSatellite.attribute( QGeoSatelliteInfo::Azimuth );
  // satelliteInfo.elevation = currentSatellite.attribute( QGeoSatelliteInfo::Elevation );
  // satelliteInfo.id = currentSatellite.prnNumber();
  // satelliteInfo.signal = currentSatellite.signalStrength();
  // mLastGPSInformation.satellitesInView.append( satelliteInfo );
  // }
  // mLastGPSInformation.satInfoComplete = true; //to be used to determine when to graph signal and satellite position
  // emit stateChanged( mLastGPSInformation );
  }

void ControlDialog::satellitesInUseUpdated(const QList<QGeoSatelliteInfo>& satellites )
{
// The number of satellites in use is updated
ui->lbl_SatInUse->setText(QString::number(satellites.count()));
// mLastGPSInformation.satellitesUsed = QString::number( satellites.count() ).toInt();

// mLastGPSInformation.satPrn.clear();
// for ( int i = 0; i < satellites.size(); ++i ){
// QGeoSatelliteInfo currentSatellite = satellites.at( i );
// //add pnr to mLastGPSInformation.satPrn
// mLastGPSInformation.satPrn.append( currentSatellite.prnNumber() );

// //set QgsSatelliteInfo.inuse to true for the satellites in use
// for ( int i = 0; i < mLastGPSInformation.satellitesInView.size(); ++i ){

// QgsSatelliteInfo satInView = mLastGPSInformation.satellitesInView.at( i );
// if ( satInView.id == currentSatellite.prnNumber() ){
// satInView.inUse = true;
// break;
// }
// }
// }
// mLastGPSInformation.satInfoComplete = true; //to be used to determine when to graph signal and satellite position
// emit stateChanged( mLastGPSInformation );

}

If you want to use and QGeoPositionInfoSource and QGeoSatelliteInfoSource simultaneously do update Qt to 5.3.1

ok

thanks...

Yes
vladmir70

works for me

thankyou very much !!!!!
