XML Error

[Ruben Ferradás]

Hello, i jave an exception when i try to open the map view, here is my code:

import java.io.File;

import java.io.FileOutputStream;

import java.io.InputStream;

import org.mapsforge.android.maps.MapController;

import org.mapsforge.android.maps.MapView;

import android.os.Bundle;

import android.os.Environment;

import android.util.Log;

import android.app.Activity;

import android.content.res.AssetManager;

public class MainActivity extends Activity {

protected static MapView myOpenMapView;

private MapController mapController;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

try{

    setContentView(R.layout.activity_main);      //THE PROBLEM IS THIS LINE

}

catch (Exception e){Log.i("----->", e.getMessage());}

AssetManager am = getAssets();

          myOpenMapView = (MapView)findViewById(R.id.openmapview);

        

        

        String filepath = Environment.getExternalStorageDirectory().getPath() + "/mapas/spain.map";

        myOpenMapView.setMapFile(new File(filepath));

        setContentView(myOpenMapView);  

        mapController = myOpenMapView.getController();

        mapController.setZoom(4);

}

}

In the XML file i only have the Mapview, the exception is: 

Binary XML file line #11: Error inflating class org.mapsforge.android.maps.MapView

Somebody knows how to fix it? thank you.

PD: sorry for my english;

Unless you provide the complete stack trace we will be unable to help you I am afraid.

Greetings,

there it is. thanks

You always need to read down the stack to the line where it says "Caused by:"

In your case it is 
java.lang.ClassNotFoundException: org.mapsforge.android.maps.MapView

This is a build error that has been discussed here a few times: the mapsforge library is compiled against, but not linked into your apk.

I do not know how you build your apks, but if you are using eclipse you will need to adjust the .classpath file and add exported="true" to the line where you link in the mapsforge library. If you are using maven, you might have a <provided>true</provided> setting for the mapsforge library.

my casspath looks like this:

<?xml version="1.0" encoding="UTF-8"?>

<classpath>

<classpathentry kind="src" path="src"/>

<classpathentry kind="src" path="gen"/>

<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>

<classpathentry kind="con" path="com.android.ide.eclipse.adt.LIBRARIES"/>

<classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.DEPENDENCIES"/>

<classpathentry kind="output" path="bin/classes"/>

</classpath>

can i add this line?: 

<classpathentry exported="true" kind="con" path="libs/mapsforge-map-0.3.0-jar-with-dependencies.jar"/>

[Ludwig]

I think type is lib:
   
<classpathentry exported="true" kind="lib" path="libs/mapsforge-map-0.3.0-jar-with-dependencies.jar""/>

[Ruben Ferradás]

still doesnt work. any other option to probe? Thank you.
