updated to from v. 0.5.2 to 0.5.6 on play store but realized that 0.5.5 (instead of 0.5.6) was installed. 0.5.5 seems to be very unstable since i cannot open projects worked on 0.5.2

using android 5.1.1

The current method of highlighting features is based on QWidget/QGraphicScene/QPainter. And makes browsing the map horribly slow.
A native QtQuick implementation is required to have an acceptable speed.

If the project and spatiallite db is on sdcard of smartphone, the points disappear after closing and ropening the project. There is no error message that points cannot be saved. The project/database on memory of smartphone is working fine

In many placed coordinate precision is limited to float precision (using the QML type point or C++ side QPointF). If ever, this should only get transformed for display.

I encountered a problem using QField with a bunch of spatialite-layers.
After reading your tweet about using spatialite OSM-Data in QField ( https://twitter.com/_mkuhn/status/748622494848917504 ) I gave it a try (with only 600MB and scale dependend visibility).
The data is loaded but the pinch zoom is not working properly anymore. The canvas is flickering when trying to zoom in and is zooming out instead. Then QField is freezing.

I tested it on two different tablets with the same experience:
Sony Xperia Tablet Z2 (SGB521) with Android 6.01 and newest QField-version
and
Samsung Galaxy Note Pro P905 Android 5.02 and newest QField-version.

I have a map using shapefiles in epsg 2272 with a WMS which gets reprojected. When the WMS gets reprojected the image is clipped. Sample data and screengrab attached.

qfield not support mbtiles raster layer. crashes when uploaded the project with mbtiles raster layer. Sony xperia tablet z1, Android 4.3

Will generate random crashes.
Looks like a memory reallocation issue.

Affected drivers:

• Shapefile
• Mbtiles

Currently the interface is optimized for tablets. As this app may also be used on smartphones with other size constraints on GUI elements there is the need to design a tweaked user interface adapted to smaller screens.

This is a meta-issue to coordinate this effort.

The following screenshot shows a problem on small screens for the identify window.

Proposal:
Disable the "follow current" button and use screen space 50/50 for map identify results.

Hi,

I have to navigate to my SD card everytime I want to change project. The open project menu has a + icon which seems to create a shortcut to a favourite folder but this is only remembered for the current session. Once QField is closed and reopened - this area is blank.

An attribute set as uneditable on QGIS is still editable in QField. However edit widgets do transfer as check boxes or value maps work in QField, so I think the issue is captive to toggling edit on or off.

Mode: Parcourir
Geometrie selectionnée: point
Type de couche: Shape

J'appui sur les points (même géolocalisation) - apparition du menu à gauche - j'appui sur le crayon - je modifie un menu déroulant - j'enregistre - je passe au point suivant - si je reviens sur le point précédent je ne retrouve pas les informations saisies - pour les retrouver je dois fermer le menu de gauche puis le ré ouvrir.

Merci

Hello,

Using QField for testing my little project tracker4R101 I have experimented some issues using WMS layers. Main issue is having some crashes when moving/panning/zooming in the project, which causes sometimes crashes (maybe related to failed download of the data?)

Attached is the QGIS project file which I use for this. You can find more details in my project site at GitHub https://github.com/jtornero/tracker4R101.git

Cheers,

Jorge

dump android < 4.3 and set android:screenOrientation to
"fullUser" If the user has locked sensor-based rotation, this behaves the same as user, otherwise it behaves the same as fullSensor and allows any of the 4 possible screen orientations. Added in API level 18.

Half of the coordinates is not visible. Displays the coordinates (WGS84), but should be EPSG: 3346 (Lithuania TM).

Sony xperia tablet z 1, Android 4.3

After the update to version 0.2.9 I still have the same problem: the black scren on startup.

My environment is:
Device: Logic Instrument Fieldbook E1
Android V. 4.2.2
Kernel: 3.4.48-02295

Attached you can find the output from Logcat

We should try to reduce the number of libraries. A system threshold is hit on some devices.

Candidates:

• QwtPolar (0.2.9 ships without)
• QScintilla
• Print support?
• GDAL monolithic build?

The project does not work with a WMS layer. When you open only visible white sheet. Sony xperia tabletZ1, Android 4.3

To refresh the GPS position shown on map, user has to long touch on GPS button and then chose "Center on actual position". The GPS red point should update his position automatically, now it's not the case.

With version 0.7.1, it becames impossible to edit data of existing features :

1°/ Long touch on a point (Spatialite point layer)
2°/ Touche on start edit button
3°/ Change some values in the form
4°/ Touch on save button
5°/ Close the form
6°/ Long touch on the same point -> data modifications are OK
7°/ Exit and start QField
8°/ Long touch on the same point -> data modifications are lost ! They have not been saved

QField does not handle bad layers at the moment
freeze when trying to open a project.

I've installed Qfield 0.3.4 on Samsung Tab4 10.1" running Android 4.4.2

There appears to be a shift in the mapping window towards the top of the screen. There is a white bar across the bottom of the screen. At the top of the screen the map and attribute box lies under the notification bar making it harder to select the correct button.

It would be great to be able to install QField without requiring a Google Play account.
This could be done either by :

• providing a single APK file to download and install
• use the F-Droid infrastructure

When I run QField, the program crashes, prompted by the "QField has stopped Unfortunately".Qt in the application output error prompt as follows:

I'm running QField on two Samsung Galaxy Tab A tablets. One (call it Tab1) has version 0.5.2 - Elbrus and the other (call it Tab2) is 0.5.5 - Elbrus. The stylus that comes with the tablet - the S-Pen - has some integration with the software of the tablet. The stylus has full functionality with QField (and other apps) on Tab1, but no functionality with QField on Tab2. The stylus works with all other apps on Tab2.

This is mainly a concern in colder weather when you can't take gloves off for very long. Non-proprietary styli still work with QField and Tab2, so that is a workaround. They are not as precise, though.

Hi, i've just install QField to my Asus zenfone 5 but it just crashed. Error: "Your application encountered a fatal error and cannot continue". Please check this, thank you! :)

I had a wms layer working but once I updated to 0.3.4 it stopped showing up in my drawing. I have a one plus one using CyanogenMod 11s. Mapfiles created in QGIS 2.8.1.

I cannot digitize in the QField mobile app at all any longer since installing the second most recent update maybe a week ago. Also, when choosing which field to digitize it shows me two entries for each, one with Capital letters (as they appear in the .sqlite database) and one with lower letters as the layers appear in QGIS layers panel. Neither allow me to create a point that is visible.

Depends on expression default value support

Probably requires Qt 5.7 to be properly implemented https://bugreports.qt.io/browse/QTBUG-50230

Qfield crash when I add a photo on android 4.4 (samsung galaxy tab 2) and android 6.0.1 (Nexus 5).
Qfield crash when I validate the photo.

Hi, is it possible to release the app via f-droid store? This would allow the use on alternative OS as CyanogenMod, BlackberryOS, SailfishOS, ... Or does it rely on Google components as Play services?

When i start QField, he dont open the last project, like mentioned in Demo Video http://www.opengis.ch/2015/01/11/qgis-mobile-0-2-demo/

If the project done on QGIS Desktop use WMS or WFS layers. It could be great if they wher showing also in QField. But QField need a place to set the WMS or WFS parameters like name, URL, ID and password. If QField don't use private/specific flux, it could be great to use OSM or Google map and so on like QGis OpenLayers plugin do (https://plugins.qgis.org/plugins/openlayers_plugin/) .

Hello,

We are using two different machines :

• samsung tab S2 8", android 5.0
• smartphone Crosscall trekker X2 android 4.4
  Project and data are the same on both machines on SD card.

With the smartphone, we manage to edit points, lines and atributes. Nevertheless with the tablet, editing doesn't work. With the last Qfield version (0.7.4) we can read this log :
Cannot start editing
Feature could not be added
Could not save changes. Rolling back

Any ideas ?
Thank's for answer

I had the first session with QField it is really great!.. I have a project in QGIS with Greek characters (UTF-8). When loaded to the QField the Greek characters are unreadable.
Any ideas what is wrong?.

When closing the side-panel, the selection should just disappear.

I have installed QField 0.3.2 on a Samsung Galaxy Note 8.0. I have a project with a shapefile layer. One of the fields, called "Time" is defined as Date (QDAte) and widget is set to display "yyyy-MM-dd HH:mm:ss", two other fields are called respectively Start_Date and End_Date, are defined as Date (QDate) and widget is set to display "yyyy-MM-dd" only.
However all fields do not automatically update when opened in QField editor, so that theoretically I'd have to insert all times and dates manually. On the other hand in QGIS for desktop everything is working fine.
When I use a spatialite layer the behavior is the same.

It may be useful to say that if a field was edited in QGIS (2.8.1), when opened in QField it displays as 2015-03-25T00:00:00, even if time was correct in QGIS. May be there a problem when copying the project file? Should I export projects and shapefiles differently, instead of just copying and pasting?

When I try to digitize a polyline, the polyline is not saved in the database, and no shown on map. I can draw the points and fill the form, but when I click on save button, nothing is saved.

Device : Galaxy Note 2014 Edition with Android 5
BD : Spatialite

created point layer with three 4 attributes. Values of two attributes can be chosen from predefined lists (Wertabbildung). One of type INTEGER, one of type TEXT. Values of the other two attributes must be entered manually (cannot be selected from predefined lists).

When digitizing data values entered manually are saved without problem. Default values from predefined lists will not be saved but must be manipulated before they can be saved.

See example in file attached
AttrTable.docx

When entering data on a new or existing object, the data of the last field edited is not saved if the cursor remains in it. To save it, the user has to tap into another field after having entered the data of the last field.

Right now there's a trashcan button that will delete features immediately. The impact can be too heavy to make it the user that easy to mess up things.

Possibilities:

• An undo option would be great because in the 90% where you DO want to delete something it's just one single click.
  E.g., show a message "feature deleted. click here to undo" for 5 seconds. The "problem" is, we try to push changes to the dataprovider as soon as possible and there may be triggers etc. attached, so once deleted it depends a lot on the dataprovider how a proper "undo" should be handled.
• A confirmation dialog. It's always an extra click. So for this, it needs to be easier to delete several features at once (imagine deleting 20 features and confirm every time, that's not a good UX). Maybe a selection could be done and then operations performed on the selection (very common in Android apps).

When doing a pan or a zoom on a map that has finished refreshing, all is ok. When doing a pan or a zoom on a map that has not finished refreshing, the map tries to refresh before the pan or zoom is finished, and the view does not display the right objects at the right place. This is frquently the case, because map can take a relatively long time to refresh, as CPU performance on tablet is not so good if tablet is not very recent. A solution could be to stop trying to refresh the map when user begins to pan or zoom.

Is the Qfield documentation available online somewhere?
