how to add more than 1 map file in mapsforge projects?

[sarahave...@gmail.com]

I was trying to use The MultiMapDataStore but seems like thats not exist in mapsforge-map-reader-0.5.0.jar lib and for some reason i cant compile mapsforge resources.

how can i add more than 1 map file or use that MultiMapDataStorein in eclipse?

[Emux]

The multiple maps feature was introduced after the 0.5 release.
So you need newer jars.

Besides Wiki you can check also the relative example in Samples.

after adding those new jars, 2 new errors appeared :

        // tile renderer layer using internal render theme
        this.tileRendererLayer = new TileRendererLayer(tileCache,
                this.mapView.getModel().mapViewPosition, false, true, AndroidGraphicFactory.INSTANCE);
        c.setMapFile(getMapFile());

1. The constructor TileRendererLayer(TileCache,MapViewPosition,boolean,boolean,AndroidGraphicFactory) is undefined 
2. the method setMapFile(File) is undefined for type TileRendererLayer

can u help me plz?

[Ludwig]

That interface has changed slightly, best to have a look at the Samples app how it is done there. 

We have just released mapsforge 0.5.1-rc1, the first release candidate for version 0.5.1. You can find the binaries here: http://ci.mapsforge.org/job/0.5.1-rc1/ 

That would be the best for moving your app forward.

Please update Getting-Started-Android-App.md  for that new interface , im so confused with importing samples app sources in my application.

[Emux]

Sorry about that,
I just updated the Getting-Started-Android-App wiki to use the new interface.

something is wrong and i cant find it , since i replaced my old 0.5.0 jars with new 0.5.1-rc1 jars i get some errors like : "Could not find class 'org.mapsforge.map.layer.overlay.Marker[]" referenced from method blah.blah.activity<clinit>.

Thank you for help.

The Marker class is certainly part of the mapsforge-map 0.5.1-rc1 jar and I find it a bit strange that that is the first missing class your app complains about. The path or packaging of this part has also not changed. 

why does it say 'java.lang.NoClassDefFoundError: org.mapsforge.map.layer.overlay.Marker[]' with [] at the end?

Probably an array?

Maybe with the replace of jars, the IDE is not yet aware of the new ones?
A project refresh or something similar could help.

[Ludwig]

Yes, obviously an array, but we do not have/export that. It seems to me more a part of his code.

maybe because of this :

Marker[] marker_red = new Marker[6];

i have same issue about LatLong too:

LatLong[] bigLatlng = new LatLong[5];

this 2 arrays was working fine in 0.5.0.

here is part of my code 

 

[Emux]

What IDE are you using?
Something seems to go wrong with the classpath.

Maybe trying to re-download the jars?

[sarahave...@gmail.com]

Im using Eclipse, i just downloaded all jars again and still have those errors.

[Ludwig]

I have the feeling this is the usual export problem again, eclipse seems funny when you adjust the jars as the build config files get regenerated and I remember that it used to drop the export declaration. 

As Emux suggested, can you check your .classpath file on the top level of your project?

You need the export keyword on all the mapsforge jars... similar to this:

<classpathentry exported="true" kind="lib" path="lib/mapsforge-core-0.5.0.jar"/>

I unselected  "Android Privet Libraries" from Build Path > Order and Export and cleaned my project but didnt fix my problem.
also i removed everything in Bin folder and restarted eclipse this didnt fixed my problem too.
tried many similar things, im wonder why i didnt have this issues with 0.5.0 jars.

Can you see the differences with version control?

No, how can i do that?

[sarahave...@gmail.com]

Do you know why this errors happened?

[Emux]

I never had to play with other settings like order or export.
I simply put the jars in libs folder in all IDEs (Eclipse, Idea, AS) and they parse it fine.

i.e. in .classpath there isn't any lib jar definition

I suggest to follow this way and try with a new clean Android project.

[sarahave...@gmail.com]

its almost 3 days that im working on what you suggested me . i tried sooooo many defrent things but here i start from step 1 again maybe you guys can help me with this really annoying issues step by step...
I created a clean android project and it worked fine on my tablet without adding any extra jar files, then i just copied jar files into my project lib folder

after this step i restarted eclipse then i refreshed my project and i run it . in console this error happened:

[2015-03-01 13:57:25 - Dex Loader] Unable to execute dex: Multiple dex files define Lorg/mapsforge/core/graphics/Align;
[2015-03-01 13:57:25 - Basir] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lorg/mapsforge/core/graphics/Align;

 

Now what should i do ?
I googled so many answers about it and i almost tried all of them but none of them carried me to the end without making new issues,some of them made my old marker[] error again for me.

[Emux]

That message indicates a mix in classpath, if finds a class more than 1 times.
Something is wrong there, have you added the jars also with IDE UI in classpath?

I suggest to try building a simple project (maybe irrelevant of mapsforge) with a single jar, to understand the IDE workings (I would try also with a clean workspace).

No i didnt, i just copied jar files directly into my lib folder from windows.

Its strange!
I just created a fresh test project again and i added a random jar file into it and it worked fine.then i started to add mapsforge jars 1 by 1 it was working fine even when i added all of them , when i removed that random jar file from my project that dex error happened again.

[Emux]

I just took a closer look at your screenshots.

You have some unneeded and mixed jars.
The needed libraries are mentioned here.

Don't mix Android and AWT jars.
Also the SwingMapViewer is a sample application, not a library.

[sarahave...@gmail.com]

Thank you so much , seems like it fixed my errors now im gonna do it for my main project to find out if that was same issue.
