这是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" >
<fragment

android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="145dp" />
</RelativeLayout>
这是主要的活动代码。
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@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;
}
}
这是清单代码。

我也添加了google_play_service库。
任何人都可以帮我解决这个错误。

Caused by: java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist.
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" />
你的日志告诉你一切：
在<application>内添加Google Play服务的版本代码，即在</application>内AndroidManifest.xml之前
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
同时在<application>内移动以下代码，即</application>内的AndroidManifest.xml
<meta-data android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyDI4t1Re46zMCY_j58DzWY07Uw5OLhyZIM">
</meta-data>

如果您知道要在地图中显示的位置名称，则可以尝试使用此代码。它对我有用。
Geocoder geocoder;
List<Address> addresses = null;
geocoder = new Geocoder(this, Locale.getDefault());
try {
//getFromLocationName returns array of address, it takes 2 parameter one place name and count of result
addresses = geocoder.getFromLocationName("Place name", 1);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
latitude = addresses.get(0).getLatitude();
longitude = addresses.get(0).getLongitude();
String label = "SomePlace";
String in = "geo:" + latitude + "," + longitude;
String query = latitude + "," + longitude + "(" + label + ")";
String ey = Uri.encode(query);
String uriLoc = in + "?q=" + ey+ "&z=16";
Log.d(uriLoc, "no log");
Uri uri = Uri.parse(uriLoc);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);

请从日志中查看此行。
引起：java.lang.IllegalStateException：应用程序的AndroidManifest.xml中不需要的元数据标记不存在。您必须在应用程序标记
中包含以下声明 <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
