Track and Map System - Android Apps and Games

Are there any apps whereby you can define a map, and then you can locate,track and mark where you are within the defined map?
If not, how do I go about developing this kind of app? Are there any any kind of existing open source solution I can use? This kind of app would of course need at least 4 android device to work I assume.
3 for triangulation (base)- The more base there is the higher the sensitivity of the map.
1 for scouting(rover)

[APP][1.6+] MM Tracker

Hi,
i created an App called 'MM Tracker' which is able to read QCT maps from Memory Map from SD Card and displays them.
The current GPS position is displayed and tracks can be recorded, saved and (re)loaded.
There is a free version called 'MM Tracker FREE' to test the App on your device.
The free version is just displaying your current position on the map.
All other features can only be used with the full version.
Features are:
Tracks are stored to SD card as GPX files
GPS track will be drawn on map
Track properties can be adapted (color, width and opacity)
Overlay Manager for Tracks, Routes and Waypoints
Waypoints can be created at GPS position or by manual entry of coordinates
Routes can be created
Displays compass on map
Map can rotate in direction of travel or by compass
Pinch zoom
Support for landscape and portrait display
MMI files can be used to search places
New maps at current position can be selected with context menu
Maps with larger/lower scale can be selected with on screen buttons
When leaving the current map a new map will be automatically loaded (when available)
'Lock to GPS' can be enabled to scroll the map while you are moving
'Screen Lock' can be enabled to prevent unwanted touch input
When device is switched off (standby) MM Tracker is still recording tracks
Displays the map scale
Volume buttons can be used to zoom in and out
MM Tracker does not support the new Memory-Map format QC3 / DRM encrypted QCT!
Important:
Due to limitations of the Android NDK currently only maps smaller than 2GB are supported! If the map is bigger than 2GB, the map tiles beyond 2GB will displayed as white tiles.
'MM Tracker' runs on Android 2.1+. For Android 1.6 there is a special version of 'MM Tracker' called 'MM Tracker 16'
The development of 'MM Tracker' is ongoing and new features will be added frequently. Feel free to suggest....
You can find all info about 'MM Tracker' here: http://sites.google.com/site/mmtrackerinfo/
Have fun...
MM Tracker is now available for Android 2.1.
As i only could test it with the SDK emulator, it would be great if you could post some feedback.
Michael
Michael,
thank you very much for releasing MM Tracker. I have downloaded the free version, and it's absolutely brilliant. I would say it works so much better than MemoryMap, since MemoryMap on WM had a problem with maps bigger than 200MB. The 2GB limit that still holds for Android makes things so much easier, in that I don't have to split maps any longer.
A few updates that I would suggest are:
speed vector
ability to read elevation data (*.qed files) and to display the elevation profile of a route or a track.
ability to read mmi data and search for a place by name.
With the above features, MM Tracker would be an ideal replacement for MemoryMap Mobile.
Keep up the good work, Michael...
ccristal
Hi ccristal,
thanks for your feedback.
The speed vector is a feature which i am currently working on. But i am not yet satisfied with the results. So it will be available with one of the next updates.
Rgearding QED and Search-Function... the problem is that i do not know how to read QED and MMI files. So for now this is not possible.
It would be great if anybody could supply a specification of the QED and MMI files
Best regards,
Michael

Well... you were not supposed to know the format of the .qct file either. If you reverse engineered that one, I'm sure you can figure out qed and mmi as well...
EDIT: oops... I just realized that the QCT format is public... but we can still work on the other two. I've just opened a .mmi file with a hex editor, it doesn't seem impossible to decode. Let me investigate some more and I'll let you know...
ccristal
Yep you are right ... QCT is sort of public As you can find various descriptions in the internet it was just about to put them in code.
As far as i know the QED format is similar to the QCT format. Only the tile size differs and maybe some other details. I will check this.
And i had a look into some MMI files. Seems to be very straight forward:
1.Section defines Categories
2.Section: Placenames and coordinates
But details have to be figured out.
If you get some more informations, it would be great if you could let me know.
Best regards,
Michael

GREAT app mapman...
Downgraded to 2.1 as dislike android 2.2..
Works well but occasionally lags a bit when moving fast cross country.
Would like to suggest OSGB grid refs and map rotation to compass direction and a compass too..
With these features it will run circles round Memory map.
Have to say there are a lot of us where am stationed who are very pleased with this app...
Looking forward to future releases and YES will be buying full version in next week or two...
regards
Lohtse
Thanks
Hi MapMan
Thanks for this great app, having been 'forced' to switch recently from an HD2 (WM6.5) to a Desire, I became resigned to the fact that Memory Map appear not to want to support Android this side of the next millennium, so the ability to use my OS maps on my HTC Desire is very welcome indeed. Thanks. !! I switched from the free app to the full version after about 2 mins of evaluation.
The App works well for my basic needs, although as commented above, the ability to see height profiles would be welcome, although in terms of my priority wish list I would welcome the opportunity to :-
1 Accurately create routes on the device - with route properties in Miles and Knots (as well as Km). I would like to be able to create routes and edit route points - perhaps by nudging them with the central optical button. This was a great problem with WM6.5 on my old HD2 where all you could do was move the very small point with a very large finger !, and perhaps in slower time look at the route elevation profile.
2 Whilst its good to see tracks displayed, I can't seem to be able to save them - perhaps I'm doing something wrong.
3 A route arrow - although not a high priority for me.
Overall a great app and given my large investment in paid OS maps, this really is worth every penny. To be honest I would have paid 10 times as much for it. I just hope you don't get hassle from MM. Thanks
Hi lohtse,
congrats, finally you got rid of Android 2.2
I spent some hours to get it on my Desire ..... tastes are different

As a lot of people were asking for it i have planned to implement some support for OS Grid. But honestly... i think map rotation is not on the "roadmap" of MM Tracker
Today i added the speed vector as a first step. I think compass could be a nice feature too.
Happy tracking,
Michael

Creating routes is definitely a feature i would like to have too. But as it is a little bit of an effort to implement, it will not be realized too early.
Tracks are saved automatically when you close MM Tracker. But you have to define a correct path for the Tracks (the latest update of MM Tracker has a more convenient dialog to choose the directories).
Regards,
Michael
P.S.: Thanks for your suggestion... i was thinking of raising the price too
hi
mapman are you uk based? if so drop me a pm...
So how easy would it be to create an Anquet Maps equivalent?
Knew I should have gone for Memory Maps!!
Hi Map Man,
Your software seems to be very interesting.
I have a winmo 6.5 and I am looking for a new phone. I know there is no solution for the new WP7 and don't like iphone. So I think about Android.
I just want to know if it's possible to import/export waypoints/tacks between Memory Map PC software and your MM tracker.
Thank you.

I think we have the same opinion there
MM Tracker creates and reads tracks as standarized GPX files.
These files can be imported/exported with MM software.
Waypoints are currently not supported, but will be in future.
Best regards,
Michael
Great, Map Man.
Hope you could add waypoints import/export in the near future.
It's the last thing that prevents me to quit my winMo 6.5 for Android
Thanks for your work !

just to make my explanation from before complete:
If you export your route from MemoryMap as GPX-track and load it with MM Tracker, you can at least see the 'route' on the sceen.
Of course navigation to WP/routes is not yet possible, but maybe this helps you...
Regards,
Michael
Hi,
just want to inform you about the latest update V1.1.5
History
Feature Added: Switch between metres, statute and nautical units
Feature Added: Tracking can be started and stopped
Improvement: Status icons in statusline
Fix: ConcurrentAcces to tracklist while loading fixed (was leading to crashes at startup)
I would recommend this update, especially because of the last item in the list
Regards,
Michael
Thanks Michael, this is such a great app! Really look forward to each update, nautical units much appreciated
How easy would it be to implement quilting / auto loading of next map?

great that you like MM Tracker
But what do you mean by "quilting" ?
Auto loading of maps is actually supported. When GPS-lock is on and you leave a map, the map with the best scale which fits to your position will be automatically loaded.
(Currently no support of subdirs, but this will be fixed)

Google Maps API - Showing only yards for golf courses

I have a golf course mapped out in Google Earth. In Google Earth, my rulers and whatnot are set to yards. Once I save the KML file and have my web developer put it onto my website, I can use it in my GPS on my Android Phone. It works great except for it shows distance only in feet and mileage. I have worked with my web developer to come up with a solution, but have had no luck. We are importing it into the standard GPS application on the Android OS. I want to work it this way so my golfers don't have to download a third party application. I am wondering if any of the following are possible.
1. Is there any way to change the scale that the GPS shows through a variable or other method?
If we could have it go from miles, down to yards at a certain distance and then feet at a certain distance to a place, it would make it ideal.
If not, can we adjust when the scale switches to feet, because currently, it stays at .1 mile down to 500ft. I need it to show feet from around 2000 feet.
If we need to run some sort of patch on the gps, it may be ok if it is seamless...can we patch the current GPS software to behave the way we want it.
I really want this to be web based for simplicity's sake, I don't think this should be that hard. It's looking more and more like we may need to use an actual custom app instead of the standard google gps. Any direction anyone can point me in would be greatly appreciated.
Thank You

[Q] Looking for a simple application to "place/move predefined markers over an image"

[Q] Looking for a simple application to "place/move predefined markers over an image"
Hello,
It seems I'm out of luck finding this on google
I'm looking for a quite simple android application that would allow the placement of predefined markers over a loaded image background ...
Typically, I would load a "map/blueprint" image and would like to place/move some markers representing people on it.
It would help in managing operations of teams/people (mainly first responders / rescue teams) on a defined geographical location ... (but without gps)
If anyone has any idea of any app that could help do that it would be greatly appreciated.
Right know I basically use a physically printed map on some magnet board and some magnets with labels on them Very very reliable but not very mobile.
Thanx in advance

Understanding Android GPS Architecture

Plz see the Attached GPS Architecture diagram 1st before reading below Article:
Location Services using GPS in Android consist of following Architectural Components
1) GPS Chip
2) GPS Driver
3) GL Engine
4) Android Framework
5) User Applications
Now Lets Understand each
GPS Chip: Radio Frequency Receiver that directly communicates with GPS Satellites
GPS Driver: GPS Driver System Software that uses Low level API’s to Communicate with the GPS chip, at the system level it may consist of a single or multiple files located at /System/Lib/hw/ Or /Vendor/Lib/hw/ files names usually starts with Prefix GPS and Postfix So (i.e gps.default.so or gps.aries.so e.t.c) depending upon the Android version and Smartphone Platform.
GL Engine: Actually the heart of this overall system.
At System level it consist of files at Path /system/bin with names like glgps or gpsd (Platform Specific)
It works using the Configuration Parameters which consist of .xml and .conf files (i.e glconfig.xml, gps.xml, Jupiter.xml, gpsconfig.xml and gps.conf, secgps.conf e.t.c). The Physical Location and names of files again depends upon Android version and Platform, but they are mostly at (/system/etc , /system/etc/gps , /vendor/etc/, /data/gps e.t.c), depending upon the Configuration and Platform, it takes initial Location Information from Cell Towers, then it take it read NVRAM , it is most important as here it store assistance data from GPS Lock, and it may also use xtra data.
NVRAM information is mostly location at /data/gps in a file with .sto ext (i.e gldata.sto) and xtra data files (lto.dat, xtra.bin, epo.dat e.t.c Platform dependent),
Using all this information Gl Engine instruct / Assist the GPS Driver, mostly Gl Engine is able to Detect multiple GPS satellites for which it is GPS driver is Programmed, but to Lock it need some extra information (Timing, Alm. / Emp.e.t.c) which it could either download from GPS satellites (Standalone Mode: very slow speed bits/sec.) or it could use internet to access SUPL/NTP servers (MS Based/MS Assisted Fast speed MB/sec.)
After all this activity, it saves all the data in NVRAM for future use.
Android Location Services : It consist of Android Framework Classes like Location Manager that Provide services to the use applications using the GL Engine.
User Applications: Location services Applications like Google Maps, Sygic, Navigon , TomTom e.t.c.
Keeping all this information in mind now lets see how the GPS Faster Fix Solutions in Market do.
Faster Fix Solutions like GPS Status & Tool Box, GPS Test, GPS Doctor e.t.c mostly handle two things.
1) Download XTRA Data (lto.dat , xtra.bin , epo.dat, gldata.sto e.t.c)
2) Modify GPS.conf (Root Required)
But this not always works.
Devices uses Google as Supl Server but most devices are unable to use it due to invalid/expired certificates and Google servers rejects the Assistance requests in such scenario Users should use SUPL.NOKIA.COM:7275 , which although slow (but something is better then nothing)
If something is wrong with GL Engine or GPS Driver, it may need Re flashing but a little could be done if GPS Chip Reception is Low or Problem is at Hardware Level, some time need soldering skills for hardware alteration (Risky)
http://forum.xda-developers.com/showthread.php?t=1318892
The Other Configuration Parameter which users could modify is xml Configuration file( Take Backup 1st) at Least a Programmer could get Debug Log to understand where things are going wrong, using below parameters.
cLogEnabled="true" acLogDirectory="/sdcard/gps" and LogPriMask, LogFacMask and also DEBUG_LEVEL (gps.conf)
Hope everyone could easily improves their GPS Performance using this guide for any platform.
Wow, thank you, this is very useful!
Neat! Thanks!
hi
can you please explain the extensive location settings from google maps ... i searched google's help and i'm still confused.
for eg, what is the difference between "report from this device" and "enable location history"?
i guess they generate the trafic info using the data from our phones ... how?
thanx!
Happy Holidays! and Happy New Year!

'report from this device' is used in latitude. latitude allows you to share your location with your 'friends'. 'enable location history' is for you only and keeps a record of everywhere you go. or at least thats my understanding of it. hope this helps
Thanks for this "sort of" schematic! Keep on making some new schematics! :cyclops:

I agree. I've always enjoyed learning about gps starting from my Garmin iQue days. After suffering with the Captivate and that horrible gps it's nice to have a phone with fantastic gps and the ability to truly use it. Good stuff here!

Hi
Speaking about GPS, is there any onchip limitation regarding the speed or location that it should grab GPS signal ?
Someone told me that it may not be possible to make it work in a plane because of US rules and security.. or around some sensitive FBI or Governments buildings (that may have signal killers) ?
Thanks

first ... with both disabled ... maps and search still search your location .. which is strange ...
second ... if i enable location history, but not report from the device ... there is no history ! or i don't know where to find it ... cause, indeed it's not in latitute ... you can select "report from the device" without selecting history ... not sure if anything happens ...
Happy New Year!
wow mind blowing and extensive work to understand all this about global positioning system ...
Simple question to OP
Can the Broadcom chipset XTRA file- lto2.dat be used for Qualcomm chipset XTRA file - xtra.bin ? and vice versa?
Thank you.

To My Understanding and Experience "NO",
putting lto2.dat file in a Qualcomm Android Phone do not improve Time To First Fix (TTFF), did'nt experimented BroadCom.
also contents of both files seems different, MediaTek processors uses EPO files instead, but it is astonishing that lto2.dat do improve their TTFF.
But no technical document to prove these experimentation .
US past policy do restrict the use of GPS above certain altitude (to deny military use of GPS), but cell phones still acquire navigation using GlONASS in Planes.
Can anyone tell me which files are responsible for GPS? I used TitaniumBackup and I suspect that I deleted these files by mistake because now I do not receive a signal outside the building

App Inventor

Hey guys
I was wondering if anyone could make me an app in app inventor.
1.Create or obtain a map of a campus in the UK, with at least ten labelled buildings. Set up an app that displays
this map on the phone or emulator.
2. For each of the ten labelled buildings, you will need to store the maximum number of computers
available. Develop your app so that when the image of a building is touched or clicked, the number
of available computers in that building is displayed.
3. Create two buttons, ‘reserve’ and ‘cancel’. Ensure that when the ‘reserve’ button is clicked, the
number of computers shown as available for that building is decremented. Similarly, the ‘cancel’
button increments the number of computers available. Make sure that operating the ‘cancel’ button
cannot increase the number of available computers beyond the maximum in that building.
Thanks.
