Android Google Maps API v2的问题（

时间：2013-11-18 21:23:46

标签： java android eclipse google-maps google-maps-api-2

我一直在尝试在Eclipse中创建一个Google Maps API v2应用，但我一直遇到一系列我不确定如何解决的错误。

几天前开始编写Android应用程序（大约两周前编码），所以这对我来说还是一个新手。

我获得了SHA和MD5，我的API v2密钥，在Google上注册了它等等。

我不确定我哪里出错！

这是尝试作为Android应用程序运行时的CatLog：

说实话，我不确定如何从那块巨大的红色中推断出任何解决方案。以下是我项目的要素：

MainActivity：

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_STATE = new LatLng(49.27645, -122.917587);
    private final LatLng LOCATION_CITY = new LatLng(49.187500, -122.849000);
    private final LatLng LOCATION_YOU = 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_YOU).title("This is you!"));
    }

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

    }
    public void onClick_You(View v) {
        map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        CameraUpdate update = CameraUpdateFactory.newLatLngZoom(LOCATION_STATE, 20);
        map.animateCamera(update);

    }

}

要测试您的应用程序，您还必须设置Google Play服务SDK，请参阅此link并将此标记添加到您的清单文件中：

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

您的logcat指向：

>11-18 16:02:19.826: E/AndroidRuntime(16453): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  
Expected 4030500 but found 0.  
You must have the following declaration within the <application> element:     
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

答案 1 :(得分：0)

从您的日志中

java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 4030500 but found 0.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

在结束标记应用程序之前移动元数据标记。
