Google Map中的NoClassDefFoundError

我无法弄清楚错误：NoClassDefFoundError。我正在尝试创建一个简单的Google地图。 Google Play服务库有问题吗？

错误： -

像这样更改MainActivity 

 import android.os.Bundle;
 import com.google.android.gms.maps.GoogleMap;
 import com.google.android.gms.maps.MapFragment;
 import com.google.android.gms.maps.model.BitmapDescriptorFactory;
 import com.google.android.gms.maps.model.LatLng;
 import com.google.android.gms.maps.model.Marker;
 import com.google.android.gms.maps.model.MarkerOptions;


 public class MainActivity extends Activity {


private GoogleMap googleMap;
MapFragment mapFragment;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main );
    mapFragment = (MapFragment) getFragmentManager().findFragmentById(
            R.id.map);
          googleMap = mapFragment.getMap();
          googleMap.setMyLocationEnabled(true);


}

   }

\和这样的清单权限

   <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission     android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

  <uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

  <!-and metadata above--> </application>


 <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="your android API key for map" />

答案 1 :(得分：0)

更新手机的Google Play服务 https://play.google.com/store/apps/details?id=com.google.android.gms

答案 2 :(得分：0)

使用FragmentActivity而不是Activity

将此代码放在ApplicationManifest文件的Application tag

下 
<meta-data android:name="com.google.android.gms.version" 
            android:value="@integer/google_play_services_version" />
