我尝试运行谷歌地图应用程序但是当我在我的xml文件中放置地图Fragmet时，应用程序停止。我认为问题在于片段映射，因为当我在没有它的情况下运行应用程序时，例如只添加一个按钮运行完美，我也将清单放回去查看 这是我的java代码：

public class Activity2 extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_activity2);

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity2, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_activity2,
                container, false);
        return rootView;
    }
}

}

这是我的XML代码

    <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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.tutorialgooglemaps.Activity2$PlaceholderFragment" >

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

</RelativeLayout>

你的logcat清楚地说了

03-14 00:47:38.619: E/AndroidRuntime(3717): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 4242000 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" />

将Google Play服务版本添加到您应用的清单

  

编辑应用程序的AndroidManifest.xml文件，然后添加   在元素中声明如下。这嵌入了版本   使用该应用编译的Google Play服务。

您需要将<meta-data>标记下的<application>添加到AndroidManifest.xml

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

这是因为最新的Google Play服务需要一个版本名称，使用<meta-data .. />内的AndroidManifest.xml来提及

更新：构建您的manifest.xml，如：

  ....<application>
 ..............
  <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyDrcKDGxUgl0Ps4u2ptOsIUCI6ooXmZ0RU" />

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

</application>
