Create a standalone map on Android

Question

I am new to Android app development and I need to create an Offline map Android app.

I used Mobile Atlas Creator to get the osmdroid.zip display format, and I don't know how to add it to my application.

Can someone show me how to use Osmdroid in my application? I would appreciate it if you provided step-by-step instructions.

Answer 1

This is the absolute project of the minumum example for Osmdroid, which I did sometime earlier.

package osmdemo.demo;

import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

import android.app.Activity;
import android.os.Bundle;

// This is all you need to display an OSM map using osmdroid
public class OsmdroidDemoMap extends Activity {

    private MapView         mMapView;
    private MapController   mMapController;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.osm_main);
        mMapView = (MapView) findViewById(R.id.mapview);
        mMapView.setTileSource(TileSourceFactory.MAPNIK);
        mMapView.setBuiltInZoomControls(true);
        mMapController = mMapView.getController();
        mMapController.setZoom(13);
        GeoPoint gPt = new GeoPoint(51500000, -150000);
        //Centre map near to Hyde Park Corner, London
        mMapController.setCenter(gPt);
    }
}

Do it in your osm_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
    <org.osmdroid.views.MapView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:id="@+id/mapview" />
</LinearLayout>

Enable slf4j-android-1.5.8.jarand osmdroid-android-3.0.5.jarthe build path. (Google is looking for where to get them)
