简单的osmdroid应用程序不起作用

Question

我试图推出一个非常简单的Android应用程序使用OpenStreetMaps工具为Android，我什么也没有，但运行时错误。

Android虚拟设备：平台2.2，API级别8，SD卡1024MiB。

我的IDE IntelliJ IDEA的11

这里是我的AndroidManifest.xml中：

<?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> 

而且main.xml中：

<?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> 

而且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; 
    } 
} 

下面是错误日志：

我还包括SLF4J-1.6.1-jul.jar，osmdroid-Android的3.0.7.jar和的android.jar （API 8）库。

怎么了？或者我必须添加到我的项目中？

Answer 1

我不熟悉IntelliJ，因为我使用Eclipse，但认为你的项目中有错误的sl4j jar。你应该使用slf4j-android-1.5.8.jar我想。您不需要Osmdroid地图项目的API密钥 - 只有GoogleMaps需要它。

下面是最小Osmdroid样品我有，它本质上是一样的你，但它集中了张地图给你一个具体的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); 

    } 
} 

。
