- Fix: Wrong (Notification) Icons where installed Version 1.018
22 September 2020 -
This is now the permanently new Google-required package in
32-bit and 64-bit versions. Also, Android 5.x is no longer supported
(again, Google is causing this).
- This version has critical bug and stability improvements.
Also, the App is now protected against a situation where the Active
Operation is not the same during a switch between a Local Database
Server and the Internet Database Server.
This situation can
occur when the App is loaded at a remote location, via the local WIFI
and a Local Database Server; But the Local Server was not synchronised
with the Internet Server (and this means the Internet Server
does not have the same Active Operation running). When the App
unexpectedly gets Internet coverage, and tries to synchronize itself
with the Internet Server, the App will sound an alarm, and will

Operation to a previous one. The App will then attempt to

can be overruled by shutting down the App, restarting, and then accept
the Operation on the other Server. The non-saved data of its existing
Operation will then be lost. Version 1.016
July 2020 - The previous version was
rolled back and re-configured for Android 32-Bit only, after problems. Version 1.015A
1 July 2020 - This is the FIRST Google
Play version including a 64 bit version of the App. Please advise any
- Fix: 'Clue' images taken while not in coverage of the Server would
only retain the last image taken.
- New: Map: The Map now supports the IPS/LKP/PLS circle system, and
also the new 'Area' Poligons with filling.
- Improved the initial installation procedure.
1 June 2020 - Bug Fix: When
multiple Operations where open, and when after a restart the same
Operation would be selected as the time before, the App would hang in
'Pending Connection' state. This is now fixed.
New: Improved transfer of all the App's Way-Points (its

Priviousely it would transmit its entire Track every time; Now it will
only transmit any parts of the Track which have not been send to the
Note: This requires the use of the latest versions of the Database
Server(s) and SARTrack MS-Windows Clients.
21 April 2020 -
New: The Messages window will now also display 'Tracker messages', that
is, messages from Radio or Satellite based Trackers. Currently
includes: Tait radios, Icom radios, and the (New Zealand only)
NZPoliceSAR satellite trackers. In addition, it is now possible to send
a Radio message back *to* a Tait radio and the NZPoliceSAR satellite
trackers. But do note: it is NOT the App which sends these messages to
the final destination; instead the App sends them to the Database
Server, which in turn sends it on to a SARTrack (Windows) Client, which
has the final connection to a Tait Base raios, or the NZPoliceSAR
satellite feed. If these are NOT available, the sending of such a
message will fail.
- Improved stability
- Improved download of tracking data from Object Trackers.
9 March 2020 -
Greatly improved the stability of the App, and it can deal much better
with the fact that the Android OS is continuously killing the App.
I also improved multiple display issues.
settings are now (in Setup):
- Connect Interval: 5 (minutes) (no longer 0 minutes)
- GPS Position: 'By movement'
- Position Interval: 15 (seconds)
- Min Distance: 10 (meters)
setting the "Connect Interval" to 5 minutes, the App will not stay
connected to the Database Server all the time, which uses a *huge*
amount of battery power. Instead it will connect every 5 minutes, do a
quick synchronisation with the Server, and disconnect.
When you take
certain action, like sending a Message, a Clue a Log entry or editing
your Personal settings, the App will make a connection to transfer the
In addition, when you now tap the 'Connection
Bar' at the bottom, you have a new option to force a 'Quick Connect' to
the Server. This can be used to (for example) load any Tasks which
where just send to you, but you have not received yet. PLEASE REPORT any
unexpected behavior or App Error warnings.
26 February 2020 -
Major fixes in relation to the Android OS killing the App all the time,
and the connection between the App Client and the App background
- Fix: The Tasking allocation to the App did not work
correctly, because the logged in People link was not updated by the
Database Server. This also requires that all Database Server are
- Notifications to the User are now done by the background
service, instead of the App's Client, because this is endlessly killed
by the operating system.
- Change the Icons of the App to make them more visible.
9 January 2020 - Fix: Problem where App would
not fully connect when only one Operation was active.
- New: Tapping on the COnnection Bar at the bottom, now gives option to
CHange Active Operation when available

Enroute after a callout with a single push of the button. This will
show in SARTrack in the Team Setup window. -
Fix: The way the password was send to the Server caused problems in
some countries with special language characters. To fix this, all
SARTrack programs including the Android App now work in a different
way. It also means that the Database Servers no longer are allowed to
transmit non-encrypted data. - Fix: the Message system had
multiple issues, now fixed.
18 September 2019 -
Fix: Still problems with Android 8 or higher, causing problems with the

New: Bluetooth APRS now works. Those of you who have an AP510
APRS tracker, please give it a go and let me know the results. - New: Log system. You can now
receive and send Logs, if you enable this in the Setup (at the

When you open the Google Map window, this will activate the GPS
receiver, and it may stay on after that. - Tasking: Fixed issue that an
attached image would not be availlable.

Database Servers to version 1.007 as well. Version 1.005
15 April 2019 - Improved way for App to request
stations and objects from the Server, and improved synchronisation.
This requires that you update your Database Servers to version 1.005 as
24 March 2019 - Major update.
Tracking system completely rewritten. The default setting of 'By
Distance' is now automatically adjusting to speed and direction. At
walking speed, the App will add a waypoint every 10 meters. The faster
you go, the longer the distance between waypoints. When you take a
corner, a waypoit is generated there.
- Notification system. Due to
the new Google requirements, this has been rewritten. Special sounds
are now installed for Messages, Tasks, Errors and later Logs.
- The way the App synchronises with the Database Servers has been
improved and made more reliable.
- Take Photo did not always work.
- The Task system now works properly, and you can now also view any
Images which are attached to a Task.
- Many other bugs and issues fixed.
Known issues: The Compass does not always work right, and on some
phones the top is partly obscured by the image containing the red line.
I don't know why that is. Please
report any problems with the App by using the Debug window, and
selecting 'Email Debug', with a short explanation what went wrong. Version 1.001
10 February 2019 -
In the last 9 months, the Android App had to be partly rewritten
because of the new requirements of Google that all existing App's must
'target' Android 8.
This has been a complete nightmare, and
basically everything stopped working, and the compiler which I must
use, was totally not ready for the changes, and as a result I had also
to help debug the actual compiler itself, until the final version came
out a couple of months ago.
However, there are still many problems,
and I really need to know from as many users as possible if the App
works correctly in the various versions of Android, and phones.
Please report any problems from the App's Debug window, and send a Bug
It may be useful to uninstall the old App first, then install fresh in
Some recommended settings:
When you enable Location tracking, the most power saving type is
"Automatic", which check every 5 minutes if the location has changed.
It will detect if you go around a corner, and it will adjust when you
go from walking to stepping into a car or aircraft.
detailed option is 'By Movement'. The GPS will be checked every 5
seconds; When a certain distance has been covered, it will save a track
point, also when you make a turn. The minimum distance is 10 meters
when you move 5 km/h or below, after that this minimum distance will
increase, so that when you do 100km/h it does not generate thousands of
When you go into the 'GPS/Compass, Send Clue, or
Map window, the GPS will stay on for as long as you are in there, or
until you minimize the App.
To save more power, you can set the
Connect Interval' to say 5 minutes. SARTrack will release hold on the
WIFI system, and stay disconnected from the Server until 5 minutes have
passed. It will then connect to the Database Server (WIFI or Internet),
synchronize, and disconnect again.
When you switch to Personal Settings, the App will make a full
connection to the Database.
Give it a try and please keep me up-to-date with the results.
9 July 2018 - Changed Debug log time to UTC so can
better compare with Database Servers. - Fix: Google Map: 'Normal'
button was missing - Fix: On restart Client, when
Service already running, did not display the Server connection
Fix: The Availability updates caused the Current Status (Assigned to a
Team) of the person to be overwritten at the Server and the SARTrack
clients. This fix requires also an
Update of the Database Server and SARTrack Client. -
New: In the Station Popup window, a new button: Send Message to
Station. NOTE: This currently only works for APRS Messages to SARTrack
Clients and APRS capable Amateur Radio radios (not to commecercial
radios like Tait, Motorola, etc).. (Double-tap on a Station in the
Station list to open the Popup) - Fix: Clue Photo attachment
did not always work due to a missing directory. Version 0.9.780C
26 June 2018 - Fix:
Change the way the screen is looking with different device displays.
- Fix: The Avavlabiliy system was not updated from the Server side.
This also requires the Database Server to be updated to version 0.9.781A
Known Issues: - The App will NOT run properly on
Android version 4.x.
- The App will run on Android Version 5.x (Lolipop) but it
will NOT be capable to connect to a Local Database Server, on a WIFI
network which is NOT itself connected to the Internet. That is, when
you have a WIFI network in the field, which has NO Internet access, but
is running a Local Database Server, Android Lolipop devices will not be
able to connect to it. This means
that the minimum recommended Android version is 6.x (Marshmallow).
