OziExplorer GPS mapping real time tracking software for Android Devices

History

Version

1.38

Added 64bit support (some devices such as Pixel 7 and Samsung S24 only support 64bit apps)
- Unfortunately to ability to load .png and .jpg maps is no longer supported for 64bit. Any maps in these formats will need to be converted using our img2ozf software.
- If your device is 64bit it will automatically use the 64bit library.
- If your device is 32bit it will automatically use the 32bit library.
Added scales (x and y axis) to Elevation and Speed profiles for the Track Tail.
Added the cumulative elevation change (Gain) and the cumulative Loss for the Track Tail.
- Will only show if the Elevation profile graph object is wide enough.
In the User Track List the track distance is now based on the original loaded track not the filtered track.
In the User Track List the number of track points is now based on the original loaded track not the filtered track.
In the User Track List added the cumulative elevation change (Gain) and the cumulative Loss for a track.
Added direction arrows to the track tail, the setting for these are in the Track Configuration screen.
Added ability to show dialog if physical hardware GPS (GNSS) is not found in device.
1.38b - fixed problem (for 1.38a) with track tail profiles not drawing (for a new track tail).

Version

1.37

GPS Information Display
- Added GPS Satellite Constellation name to GPS Satellite display.
- The Satellite fix graph now shows the satellites used in the fix at the top.
- Satellites used in the fix are now colored in green.
Added an additional "Map File path", now 2 paths available in configuration.
- Both are checked in map searching.
Increased the size of the Folder Selection dialog and allowed wrapping of the folder name text.
On some devices when stationary the GPS Heading always indicates North.
- An option has been added to GPS Configuration called "Tick if Moving Map Pointer always points North when stationary."
- When ticked OziExplorer will hold and use the last heading just before coming to a stop.
Screen Designer
- Added "Back to Last Page" button.
- Added "Start/Stop Track Logging to file" button.

Fixes
- Due to Android OS changes the update app function may have been broken.
  - Many changes made to the update method for this version.
- Some other minor fixes.

Version

1.36

Now supports Android 11, fixed problem with recognising external sdcard.
Fixed issue with High aspect ratio screens having black bars.

Version

1.34

Have increased the minimum version of Android supported to remove the message "This app was developed for an older version of Android" (message appears in Android 9 and 10). OziExplorer now supports from Android Version 4.1 upwards.
Android 10 has forced a new New Device ID method to be developed. The previous Device IDs will still be used where possible for checking the license so old/current licenses should still be valid even though the displayed Device ID is different.
Supports new permission system for Android 6 and above - permissions are requested at runtime.
The Last map zoom is now remembered when app is closed and restarted.
Better visual support for high density screen devices. This means objects such as waypoints and moving map point will now appear larger on high density devices - this can be adjusted in configuration.
Added support for loading GPX files through screen designer (new version of screen designer V1.14 required).
Added ability to download and install OziExplorer update direct from the app (from this version on).
The state of OziExplorer (last map, odometer values and other on the fly settings) are now saved when changed instead of only saving when exiting the app.
The Map name in the action bar (title) is now the map name instead of the map file name.
Removed SMS messaging option from this version (for now anyway).
Fixed crash which would happen occasionally when rotating device.
Many other bug fixes.
NOTE : OziExplorer Version 1.31 may not notify that an update is available.
We changed to a secure server and this has caused issues with the update address.

Version

1.30 / 1.31

Fixed issue where Android 8 would not allow reading the GPS when the App was in the background.
In later Android versions the title bar above the map was very large, that has been fixed.
Added the ability to import waypoints and tracks from GPX files (see new GPX menu).
Added the ability to export waypoints to GPX file.
Added option for solid moving map pointer.
Other minor fixes.

Version

1.29

Fixed issue with Android 7 no longer allowing reading of the "root (/)" folder.
- Stopped the crashing when "root (/)" folder selected using the ".. up one level" option in the folder list.
- Tried to make the sdcard names in the OziExplorer folder list more user friendly.
- Added sdcard and storage folder names to root folder and storage folder lists so they can be selected.
- The actual folder locations and names are not changed, only changed on the displayed list in OziExplorer.
Added "Save Track Tail to File" menu option.
Decreased the odometer sensitivity to stop odometer creep while stationary.
Fine tuned the display of waypoints on the map when there are a lot of waypoints.
Made some color changes of edit fields on input screens.
Fixed a few issues.

Version

1.28

Android 6 (Marshmallow) caused a crash when loading ECW map images - has been fixed
Android 6 (Marshmallow) changed the name of the external SD card and this means the OziExplorer Map File path is no longer valid. OziExplorer now notifies the user that the path is no longer valid and to set it to the correct path in configuration.
Added the ability to turn off waypoint dragging in Waypoint Configuration - the default is OFF. I did this to remove the accidental activating of waypoint dragging. Improvements should be made to waypoint dragging in future versions.

Version

1.26 / 1.27

added new (better design) screen page files (large screen size only) - old page files are included and can be loaded manually if you prefer the old ones.
added waypoint and route waypoint dragging and edit/delete options by tapping on objects (still needs some work I think)
- turn off GPS Tracking
- double tap on screen near objects
- drag by dragging handle
- double tap handle for menu to edit / delete
increased the size of system pop-up messages slightly
increased track tail length to 3000 points
the options menu (small Android menu on bottom of screen) is no longer used.
- The options have been moved to the screen or the Main Toolbar
increased size of the "Back" and "Finish" buttons on top of menus
increased the size of text in nearest waypoint list
the device compass can now be used for the heading (experimental), turn on in Moving Map configuration
added drawing of a compass around gps position pointer, turn on in Moving Map configuration
- will add configuration options for color and transparency in next version
increased number of screen designer parameters to 400
look ahead for the GPS pointer has been added, configure in Moving Map configuration
user pointers added, configure in Moving Map configuration
map scale increased slightly in size
route navigation will now start at the nearest route waypoint
max zoom increased to 1000 (for ozf maps only)
fixed - when changing maps "Image not loaded" would be displayed and map was not loaded, now fixed - took me a long time to find this bug
fixed - text not adjusting size in nearest waypoint list for high density devices
fixed - gaps being created between points in track logging to file
fixed - most of the random lines in drawing track tail
fixed - route distance in reverse not showing
fixed - the button active state colors for all buttons where necessary
fixed - Odometer start/stop and reset messages now work for all odometers
fixed - bonne map projection
fixed - track tail color button now changes color to new setting (after change in configuration)
fixed - Page menu names in page menu after loading new page file

Version

1.25

Fixed problem with OziExplorer crashing on certain devices on startup.
Fixed problem with the map scale bar not displaying correctly for "nm / meter" distance unit setting.

1.24

The Kitkat version of Android no longer allows apps to write to the external sd card.
- OziExplorer now checks if the "Data File Path" you select can be written to, if not it is not allowed.
- However the "Android/data/OziExplorer.Main/files" folder on the external sd card can be used as it is owned by OziExplorer.
- CAUTION - all files in this folder will be removed if OziExplorer is uninstalled.
- It is hoped the next Android version (lollipop) will provide a solution so developers can use the external SD card.
Track logs are now stored in a TrackLogs sub-folder under the Data Path.
Waypoints are now stored in a Waypoints sub-folder under the Data path.
Increased the number of waypoints from 10000 to 100000.
- The existing waypoint file (waypoints.wba) is converted on first run to WaypointStore.wba and WaypointSetStore.wbs
- The old waypoints.wba file is renamed to waypoints.wba.old
The deleting of a waypoint set has been fixed.
Added more position display formats in waypoint editing.
Added a map scale, turn on and off in Units configuration, drag the scale into position on the map.
Added ability to project a new waypoint from an existing waypoint by specifying distance and bearing.
- This is done from the waypoint list by pressing on the waypoint to project from.
Fixed, waypoints from a gpx file would be located incorrectly if the map was not wgs84 datum.
Fixed, under some circumstances the wrong route was loaded from a .rte file.

1.23

Fixed problem with the first loaded track not showing.
Fixed problems with changing track properties.
Fixed problem with wrong waypoint being selected in waypoint list search.
Fixed some issues with Bluetooth connected GPS.

1.22

See the help on the web site for details on how to use the new functions.
Added direct support for Bluetooth GPS.
Added ability to specify a .wav file for each waypoint proximity, the sound is played when your position enters the waypoint proximity.
Added ability to automatically load use tracks form a folder, all tracks in the folder are loaded as OziExplorer starts.
The number of user tracks which can be loaded has been increased to 100 with 100000 points.
GPX files containing waypoints can be imported, use Import Waypoint File menu option.
A display datum, which is used to display positions in any datum can now be specified in Units Configuration.
The waypoint list now has a search function.
A User Track list has been added and the line color and width can now be modified for each loaded track.
Added "Load User track" button to the screen designer.
Added "Unload All User Tracks" button to screen designer.
many bug fixes.

1.21

Fixed gaps being created in track tail logging.
Changed "pinch to zoom" - a pinch now only changes 1 zoom level at a time.
Fixed waypoint colors when exported to file.
Fixed "NM - feet" configuration setting not working correctly.
The Track Tail now plots on top of user tracks.
Added Track Tail Point Log Distance and Track File Point Log Distance parameters to configuration.
- These parameters are the maximum distance traveled before a track point is taken.
- Other factors such as direction or speed change also cause track points to be logged.
- Setting these parameters to low values causes more track point to be logged.
- Example - setting to zero would log all track points.

1.19/1.20

I intended to have more features added for this version, didn't quite get them finished before I had to release.
Version 1.20 - Fixed problem with loading ozf4 maps.
Added support for the new ozf4 image format.
Waypoints now draw in the colors stored in the waypoint file.
Added better editing for waypoints
- Edit waypoint Colors
- Edit position in lat/lon or UTM
Increased the maximum size allowed for waypoints in waypoint configuration.
Changed the track logging algorithm to give a more accurate track.
Fixed messages not showing in Android 4.
Added the ETRS89 datum.
Fixed many small problems.

1.18

Fixed many small problems.
Now supports both ARM and X86 cpu types. X86 support is required for those running Android on a PC.

1.17

Fixed major problem of OziExplorer not being able to see the external sdcard when there is both an internal and external sdcard.
OziExplorer should now only show the sdcard folders when using the OziExplorer folder selector (not all the folders on the device).
Fixed VMG, calculation was not correct.
Fixed ETE/ETA display for many parameters including average speed calculations.
Fixed the min altitude display (was displaying the max altitude).
Fix grid coordinate display, coordinates were correct for UTM but not other grids, now fixed
Added French language.
other minor fixes.

Version

1.16

Added many different languages. If you would like to do a translation see the Translation page link on the OziExplorer for Android web page.
Some Android devices report the speed incorrectly - out by a factor of about 2 - the GPS std nmea sentences report the speed in knots, android reports it in meters/sec, the conversion between the two is about a factor of 2, could it be that the programmers who wrote the gps drivers for these devices did not notice that android requires meters/sec. OziExplorer will now read a speed factor from a file called speed_factor.dat, it is a simple text file, the first line in the file is the speed factor - example 0.5 . The GPS speed is multiplied by the speed factor. You need to create the speed_factor.dat file yourself and place it in the OziExplorer folder on the sdcard.
Fixed compass not working correctly when bearing unit set to magnetic.

1.15

Added Czech Language Translation. If you would like to do a translation see the Translation page link on the OziExplorer for Android web page.

Version

1.14

Added Language Translations - only English and German available so far. If you would like to do a translation see the Translation page link on the OziExplorer for Android web page.
Fixed (mostly) the parameters on the configuration screens being cut off on the right for narrow screens.
Fixed error in Route waypoint distance and bearing calculation.
Fixed Clear Track Tail Button - now works.
Fixed error in ground height display from SRTM height data.
Map Find now positions the new map at the same position as the previous map.

1.13

Fixed bug in editing waypoint positions.
Waypoint List sort no longer case sensitive.
Range Rings around current position added - configure on the Moving Map configuration page.
Waypoints proximities added - proximity can be added on waypoint edit page and their display and checking configured on the Waypoint configuration screen.
Route Waypoints can now be edited. The Route name can also be edited.
SMS position messaging now has the ability to add ID to start of message (see help).

1.11 / 1.12

1.12 - minor bug fix
Fixed problem with running on Android 4.
Fixed Irish Grid.
Some other minor problems have been fixed.
No major changes at this stage.

1.10

There is no need to uninstall the previous version (unless it is the very old alpha version).
This is a major update - there are many changes.
Please NOTE - the OziExplorer Android ID will change with this version - however we still check your license against the old ID as well so it still should work. In some cases you may need to re-enter your license.
Press and hold on any button for 2 seconds to have displayed a hint of what the button does.
Added screen page file support and released the OziExplorer for Android Screen Designer to design your own screens.
Default page files are provided.
Page files designed using the Screen Designer can be loaded (Note : OziExplorerCE page files cannot be used).

3 Odometers added.
Ability to send and receive positions by SMS.
Menus and Toolbars (Toolbars are just menus) can be modified by the user.

1.09

see version 1.10 for changes

1.08

improved memory management, should be better on the Samsung Galaxy tab and other Honeycomb devices with 1280 x 800 resolution screens.
improved ECW support.
- added zooms down to 1% (but very slow to redraw)
- added low resolution intermediate images for faster map drawing. A low resolution map image is displayed first, followed by a medium resolution then the normal resolution.
fixed waypoint list issues with wrong waypoint being edited.
many other minor improvements and bug fixes.

1.07

fixed - if a map was loaded with a different datum the waypoints and tracks would move.
fixed - the "Track Tail" was being collected in the map datum - it is now collected in the WGS 84 datum. The Track Tail parts collected prior to this version may not plot in the correct location. This applies only to the track tail not to tracks logged to file.
fixed - user track drawing now draws all 25 loaded tracks.
added the ability to automatically reduce the number of track points in a track as it is loaded using a "smart" algorithm. This allows more user tracks to be loaded if needed. The track reduction factor can be configured in track configuration - the higher the number the more points are removed.
increased the total user track points which can be loaded to 30,000.
tracks can be automatically loaded when OziExplorer starts by listing the track file names in a file called "TrackLoadList.txt" - see the help for details.
fixed - speed unit "knots" not being remembered.
changed map zooms from 100/80/60/40 to 100/75/50.
the OziExplorer screen page can be changed by swiping the finger quickly in either direction along the bottom of the screen. This was too sensitive and has been fixed.
add User grid "User (TM)" to position display.
other minor fixes.

1.06

Added geoid correction for GPS altitude.
Added ability to specify location for Map File and Data File paths.
Added MGRS to list of position formats for coordinate position display.
Moved configuration files to main memory so the sdcard can be used in other Android devices running OziExplorer. The configuration files are extremely small (only a few hundred bytes).
Added option to restore configuration to defaults.
Added option to download new version apk file to the sdcard. It can then be installed with an AppInstaller.
Fixed loading of maps with international characters in the name.
Fixed crash if splash screen is touched during start up.
many other minor fixes.
