Bin / [FAQ]
« on: November 29, 2010, 15:14:09 »
Update 9.11.2012

TOPIC OUTDATED (moved to bin)

    • New (unpublished) application builds? - here!
    • Manual? - yes, I wrote some texts, here (nice in mobile browser)

  • QUESTION - Why so many permissions?
    Just read this - http://

  • QUESTION - I have a problem, what to do?
    First request - don't give a negative commentary on market or low stars. If problematic feature worked and now not, it should work again. If you want to use Locus and want to repair this issue, you should
    • check this discussions, if your problem is not already solved
    • create new topic with your issue here, and hope that some kind soul find solution
    • send me crash log from "locus/logs" directory on locus(@) email
    • describe me your problem on same email as above
    and I'm sure we find solution. Negative rating sends application between trash, and my taste to work also. Thanks.

  • QUESTION - How to create maps on computer?
    Just read this - http://

  • QUESTION - How can I use my own very nice icons?
    Just read this - http://

  • QUESTION - I like my old OziExplorer maps, can I use them?
    Just read this - http://

  • QUESTION - I'm an developer, how can I send points to show on Locus?
    Just read this - http://

  • QUESTION - Why basic map initialization takes so long?
    When I change format of initialized files or you just create new map or add your custom, application need to create some configuration files. Time needed for creating is based on type of map

    • TAR maps - create bounding box of map. More time takes initializing map tiles directory. I have to find every tile and cache his byte[] position if file. Then I should load this tile directly without moving through whole file. This takes really long time ..

    • SQL maps - also bounding box and also numbers of available zooms. SQLiteDB format is little weird, so I have to go through whole database and find unique zoom numbers. For this I use this "SELECT DISTINCT z FROM table_tiles" ... which on big map files takes soooo long ...

     so, take excuse from me, but this initialization is really needed. On second side, thanks to it, maps are really fast and next starts are fast too. About frequency of configuration file changes - I really don't like to do this, so as I know, file changed in version 0.4.0 and now in 0.6.10. And I hope that this is enough for a long time.

  • PROBLEM - Tar compression error - maps cannot be downloaded and compressed
    This error is mystery for me. Sometimes someone write me about this. On my phone this never happen - unfortunately. But solution is to delete whole cache directory. You will loose map that is currently downloading, your cached Online maps and some cached indexed files. But I believe, that then all will be working fine...

Information / [MANUAL] - CUSTOM ONLINE MAPS (updated 25.7.2011)
« on: November 29, 2010, 14:53:04 »
Current manual for Custom online maps support in Locus is moved on WIKI page ... nline_maps

Solved / Icons for POIs
« on: November 27, 2010, 17:46:20 »
So, also question from me ...

currently I'm using few icons from http://

I thing they're really nice, they also not force me to set application as open source (which I'm not a big fan). But ... there's lot of icons and I cannot choose which are rights. All of them is just too much ...

So, place for you to choose and say me which icons you want or miss in application, if you want to sort them to any categories or if have any other source of nice map icons for free use. I'm not a graphics co it's impossible for me to create special icons for Locus ...

I'll be very glad for your opinion

so ...
  it's really big amount of emails, market commentars and others, than want after me some implementation of "Points handling" ...

  just try this release candidate ... ;)

  hint: to show points, you have to CHECK them ... it's not much intuitive think, don't have idea how to do it better ... I NEED your feedback ;)
  enjoy ...

Developers / [DEV] - (DEPRECATED) show points on map
« on: November 16, 2010, 07:14:40 »
Simple solution for using Locus as external viewer of points from other applications!

6.7.2011 - This method is DEPRECATED - use new API instead - viewtopic.php?f=29&t=767

[s:ounfezv9]19.4.2011 - New update of calling method - version 2

working for version >= 1.5.3

simple code example says more then few pages of words (use commentary as helping solution)

Code: [Select]
private void callLocus() {
ByteArrayOutputStream baos = null;
DataOutputStream dos = null;
try {
   baos = new ByteArrayOutputStream();
   dos = new DataOutputStream(baos);

   // version

   // write objects names
   dos.writeUTF("Points from my application");
   // write category count - here I write three categories. Categories are defined as
                    // array of points that share same map icon!
   // write categories
   // flush data to output stream
   // create intent with right calling method
   Intent intent = new Intent();
   // here put data into intent
   intent.putExtra("extraDataSomeName", baos.toByteArray());

   // finally start activity
} catch (Exception e) {
   Log.e(TAG, "callLocus()", e);
} finally {
try {
if (baos != null) {
baos = null;
if (dos != null) {
dos .close();
dos = null;
} catch (Exception e) {
// catch not needed

private void writeCategory(DataOutputStream dos) {
try {
// convert resource to byte array
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon_gc_wherigo);
ByteArrayOutputStream baos2 = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos2);
byte[] image = baos2.toByteArray();

// write image data or size '0' and no data if use default image of Locus (currently just red dot)
                       - so if you want write image use this
                        dos.writeInt(image.length); // image size
dos.write(image); // image data
                        - and if you don't want use only this

// write all points now
int pointCount = 1000;
for (int i = 0; i < pointCount; i++) {
// write item name
dos.writeUTF("name_" + (i + 1));
// write item description
dos.writeUTF("some description with <html>tags</html>!");
// extra values (describe below - optional)
// write latitude
dos.writeDouble(50.0 + 0.01 * i);
// write longitude
dos.writeDouble(14.0 + 0.01 * i);
} catch (Exception e) {
   Log.e(TAG, "writeCategory()", e);

Extra values written in code can be used for extending possibilities which user can do with point

currently supported:
    Call-back - "intent;ButtonName;com.super.application;com.super.application.Main;returnData;someStringData"
      intent - just identifier
        ButtonName - String that shows on button
        com.super.application - The name of the package that the component exists in
        com.super.application.Main - The name of the class inside of com.super.application that implements the component.
        returnData - String uder which data will be stored. Can be retrieved by String data = getIntent.getStringExtra("returnData");
        someStringData - data stored in intent at returnData StringExtra place

      Actual application that use this feature

      Testing / [APP] - version 0.4.0 RC

      Hi to all,
        after two days of work, I completely transcribed methods for downloading maps. I wanted to do a long time before, but finally ...

        - so please, try it and help me to catch all bugs or improve things that are not quite intuitive.

        - look on icon design. It's no my own, cause I'm not graphically talented. I someone want to create graphics for Locus, or if you know any place with nice icons, it will be very welcome :)

      News & Hints / [FAQ]

      • QUESTION - how to download cartridges?
        • Android web browser (and extensions like Dolphin Browser, ...) have bug when downloading GWC files (as well as other file types, for example locations on So for correct work, you have to download GWC files thanks to your desktop computer. Use firefox, opera, internet explorer, just whatever but DO NOT USE PHONE BROWSER, PLEASE!
        • Thanks to fuhur testing - Opera Mobile browser allow direct download of cartridges in field!

      • QUESTION - how to upload completed savegame GWS files?
        • there are NO savegame files GWS as on other platforms. This feature is not currently implemented. Instead, WhereYouGo, as well as OpenWIG, use inner OWS format which cannot unlock game on Wherigo pages!!!
        • so, to complete cartridge, you have to use UNLOCK KEY. If this is not implemented in cartridge, ask creator, to do this!

      Released / [APP] - version 0.3.1

      - fixed problems with downloading map on some areas

      « on: October 11, 2010, 12:43:11 »
      application version: 0.4.8
      playable: YES
      problems: little
       - missing map of smallest house, fortunately it's well known traditional cache


      For creating Offline maps on PC is absolute perfect application Mobile Atlas Creator (Mobac). I’ll not describe here how to work with this software, but I’ll tell what to do, to create maps for Locus, which is not in Mobac output list. This manual now contain two methods. One is for creating TARED map files, almost same as Locus create during own map creating process. This is supported since version 0.2.0. Second is what Locus fully support since version 0.6.10. This is SQLiteDB map type. I currently not tested which is faster, it's just on you which choose. SQLiteDB is easier to create. Also SQLiteDB can have unlimited size (TARed maps are suggested not to be bigger then 1GB), but require more time to initialize!

      So, let's create it ...
      I suggest to run Mobac with custom "run.bat" file, containg:
          java -jar Mobile_Atlas_Creator.jar -Xmx 1024M
       this allow mobac to use enough memory to download really big maps <!-- s;) --> ;) <!-- s;) -->

      First step, in Settings -> Map size -> Maximum size – choose biggest value. (screenshot 1)

      SQLiteDB Maps - needed version: 0.6.10 and higher
      • Important is output format. Set it to BigPlanet/RMaps SQLite.
      • Choose area and start creating (screenshot 2).
      • After map creating, only thing to do is copy created file (rename as you want) into Locus/maps on SD card, and that's all <!-- s;) --> ;) <!-- s;) -->

      WARNING: Due to limitation of Android platform, create maps smaller then 2GB (more here)!!!

      TARED Maps - needed version: 0.2.0 and higher
      • Important is output format. Set it to TrekBuddy tared atlas.
      • Choose area and start creating (screenshot 2).
      • After map creating, only thing to do is copy all tar map files, into one directory, so in my example, I created directory Europe OSM, and into this (as on screenshot 3), I copied all tar files created by Atlas Mobile Creator.
      • Whole directory copy into /sdcard/Locus/maps and start application (you have to wait for a a while (up to few minutes with 1GB file) to initialize all map files). Enjoy
      Warning: highly suggest not to download files bigger then 1GB (may cause Out of memory errors on Android machines with lower Java application memory) !!!
