问题
I'm trying to launch a very simple android application using OpenStreetMaps-Tools for Android, and I have nothing but runtime errors.
Android virtual device: Platform 2.2, API level 8, SD card 1024MiB.
My IDE is IntelliJ Idea 11.
Here is my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="test.osmdroid005"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="7" />
<application
android:label="@string/app_name" >
<activity
android:name=".TestActivity"
android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest>
And 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:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="(my-google-key)"
android:clickable="true"
/>
</LinearLayout>
And TestActivity.java:
package test.osmdroid005;
import android.app.Activity;
import android.os.Bundle;
import org.osmdroid.views.MapView;
import test.osmdroid005.R;
public class TestActivity extends Activity
{
protected MapView mapView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
}
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
Here is error log:

I also included slf4j-1.6.1-jul.jar, osmdroid-android-3.0.7.jar and android.jar(API 8) libraries.
What's wrong? Or what I must add to my project?
回答1:
I'm not familiar with IntelliJ as I use Eclipse but think you have the wrong sl4j jar in your project. You should use slf4j-android-1.5.8.jar I think. You don't need an API key for an Osmdroid maps project - only GoogleMaps requires it.
Below is the smallest Osmdroid sample I have, it's essentially the same as yours, but it centres the map for you to a specific GeoPoint
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;
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);
}
}
.
