关于android的MapView问题，求教大神解救
想使用google map api,但使用的时候总是被强制关闭。不知道为什么，android新手。
PS：apiKey 、权限什么的都是按照例子一步一步做的。
下面是main.xml文件：
<?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"
  >

  <com.google.android.maps.Mapview
  android:id="@+id/map"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:apiKey="0qHIu1zAnyTA1-dCOPJKideYeMucl5oQXFvILLw"
  android:clickable="true"
  android:enabled="true" 
  />

</LinearLayout>

AndroidManifest.xml文件：


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="android.guan"
  android:versionCode="1"
  android:versionName="1.0" >

  <uses-sdk android:minSdkVersion="7" />
  <uses-permission android:name="android.permission.INTERNET"/>
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
   

  <application
  android:icon="@drawable/ic_launcher"
  android:label="@string/app_name" >
   
  <activity
  android:label="@string/app_name"
  android:name=".GoogleMapTestActivity" >
  <intent-filter >
  <action android:name="android.intent.action.MAIN" />

  <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
  </activity>
  <uses-library android:name="com.google.android.maps"/>
  </application>

</manifest>


源代码：


package android.guan;

import com.google.android.maps.MapActivity;
import android.os.Bundle;
import com.google.android.maps.*;
public class GoogleMapTestActivity extends MapActivity {
private MapView mapview;
private MapController controller;

  /** 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.map);
// controller =mapview.getController();
// mapview.setSatellite(true);
// mapview.setBuiltInZoomControls(true);
   
   
   
 
  }
   
 

  @Override
  protected boolean isRouteDisplayed() {
  return false;
  }
}
