Question

我下载了GoogleMapsDemo应用程序的项目，它没有在Eclipse上出错。但是在genymotion模拟器中它一直说不幸的是应用程序无法启动。

它的MY Android清单：

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

    <activity
        android:name="ca.sfu.cmpt276.bfraser.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

它是我的主要活动：

package ca.sfu.cmpt276.bfraser;

import android.app.Activity;
import android.os.Bundle;
 import android.view.Menu;
import android.view.View;

import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
 import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

 public class MainActivity extends Activity {
    private final LatLng LOCATION_BURNABY = new LatLng(49.27645, -122.917587);
    private final LatLng LOCATION_SURRREY = new LatLng(49.187500, -122.849000);

    private GoogleMap map;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_main);

    map  = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

    map.addMarker(new MarkerOptions().position(LOCATION_SURRREY).title("Find me here!"));
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
    }

     public void onClick_City(View v) {
     //     CameraUpdate update = CameraUpdateFactory.newLatLng(LOCATION_BURNABY);
    map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
    CameraUpdate update = CameraUpdateFactory.newLatLngZoom(LOCATION_BURNABY, 9);
    map.animateCamera(update);
     }
    public void onClick_Burnaby(View v) {
    map.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
    CameraUpdate update = CameraUpdateFactory.newLatLngZoom(LOCATION_BURNABY, 14);
    map.animateCamera(update);

     }
    public void onClick_Surrey(View v) {
    map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    CameraUpdate update = CameraUpdateFactory.newLatLngZoom(LOCATION_SURRREY, 16);
    map.animateCamera(update);

      }

     }

Answer 1

如果您想使用Google服务（例如Google地图），则需要先为Android设置Google Play Services，然后您可以按照here的说明进行操作。（获取您自己的API密钥，放入AndroidManifest.xml等）
我建议您使用真实设备进行测试。如果您想将Genymotion用作模拟器，则还需要先get the google service。有关详细信息，请参阅here。

Genymotion just不启动Google Maps Demo Application-Eclipse。
