我在SO上关注了很多问题和答案，但结果是一样的。

我的清单是：

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

        <activity

            android:value="something-something" />
    </application>

</manifest>

我的MainActivity.java：

import android.app.Activity;
import android.os.Bundle;      
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.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 {
      static final LatLng HAMBURG = new LatLng(53.558, 9.927);
      static final LatLng KIEL = new LatLng(53.551, 9.993);
      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();
        Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
            .title("Hamburg"));
        Marker kiel = map.addMarker(new MarkerOptions()
            .position(KIEL)
            .title("Kiel")
            .snippet("Kiel is cool")
            .icon(BitmapDescriptorFactory
                .fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to hamburg with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
      }
}

我的布局文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.MapFragment" />

</RelativeLayout>

它与我从某些网站获得的完全相同。有人可以帮我从这里出去吗？？谢谢!!

Answer 1

你的locgcat清楚地说了

Caused by: java.lang.IllegalStateException: The meta- data tag in your app's AndroidManifest.xml does not have the right value. Expected 4323000 but found 0. You must have the following declaration within the element:

尝试使用<meta-data>文件中<application>标记下的manifest.xml标记添加Google Play服务版本，例如

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

Answer 2

我感到困惑的是，需要两个元数据。

 One with api key and another with google service.

另一个我感到困惑的地方是，我不知道是什么

android:value="@integer/google_play_services_version"意思是。

所以你应该简单地复制粘贴线。并且只能稍后试着

启动Google Map v2时出错
