MapView和錯誤

Question

我有一個mapView的問題。這是代碼：

Android清單：

<uses-sdk android:minSdkVersion="8" /> 
<uses-permission android:name="android.permission.INTERNET"/> 
<application 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" > 
    <uses-library android:name="com.google.android.maps"/> 
    <activity 
     android:label="@string/app_name" 
     android:name=".TestjmkapActivity" > 
     <intent-filter > 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

活動：

package test.pl.pl; 

import com.google.android.maps.MapActivity; 
import com.google.android.maps.MapView; 
import android.os.Bundle; 

public class TestjmkapActivity extends MapActivity { 

    MapView mapView; 
    /** Called when the activity is first created. */ 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     mapView = (MapView)findViewById(R.id.map); 

     mapView.setBuiltInZoomControls(true); 
     mapView.setTraffic(false); 
     mapView.setSatellite(true); 
     mapView.setStreetView(true); 
    } 

    @Override 
    protected boolean isRouteDisplayed() { 
     // TODO Auto-generated method stub 
     return false; 
    } 
} 

佈局：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

<com.google.maps.MapView 
    android:id="@+id/map" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_height="100dp" 
    android:layout_width="100dp" 
     android:enabled="true" 
    android:clickable="true" 
    android:apiKey="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" 
    /> 

</LinearLayout> 

此是我在logcat中得到的，當我嘗試啓動它時：

問題在哪裏？

Answer 1

也許這條線在XML的MapView使它失敗：
