现在，我创建了一个新的项目，这里是其完整的code： - 的
Now I created a new Project and here is its complete code:-
Activity.java 的
public class MapActivity extends FragmentActivity
{
private Context context = this;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
GoogleMap gMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
Log.e("Maps", "Result int value::" + result);
switch (result) {
case ConnectionResult.SUCCESS:
Log.e("Maps", "RESULT:: SUCCESS");
break;

}
gMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
gMap.setMyLocationEnabled(true);
Log.e("Maps", "------EOC-------");
}
}

这是结果，缩放选项，在图形页面没有地图空白屏幕。
我按照每一步中提到： -

推荐答案
请检查..
-
检查是否存在于你的项目中包含了Android的支持 - v4.jar的库文件夹中。
check if the "libs" folder containing the "android-support-v4.jar" exists in your project.
Android的支持 - v4.jar位于/extras/android/compatibility/v4/android-support-v4.jar在你的Android的SDKdrectory。
"android-support-v4.jar" is located in "/extras/android/compatibility/v4/android-support-v4.jar" under your "android-sdk" drectory.
运行项目之前，必须设置你的项目构建的目标，以谷歌API的，而不是Android的XX版本：选择你的项目，然后单击在Eclipse项目>属性>项目构建目标，并选择任何谷歌API的，然后在手机上运行您的项目。如果使用模拟器，还必须设置仿真器连接到任何谷歌的API的AVD。
Before running your project, you must set your project Build target to "Google APIs", not Android x.x. version : Select your project and click Project > Properties > Project Build Target in Eclipse and select any "Google APIs ", and then run your project on your phone. If you use the emulator, also MUST set the AVD of the emulator to the any "Google APIs ".
再次，你不需要为了创建新的谷歌地图API密钥，以测试你的项目，只要使用默认提供的API密钥，表示为键浏览器的应用程序（与查阅情况） 在你的谷歌API控制台。
Once more, you don't need to create the new Google Maps API key in order to test your project, Just use the default provided API key, which is shown as "Key for browser apps (with referers) "in your Google APIs Console.
最后，最重要的是加入谷歌Play业务作为一个Android库项目如下：
Finally, the most important is to add Google Play services as an Android library project as follows:
选择文件>导入> Android的>现有的Android code进入工作区，然后单击下一步。 选择浏览...，输入/演员/谷歌/ google_play_services / libproject /谷歌播放services_lib，然后单击Finish。
Select File > Import > Android > Existing Android Code Into Workspace and click Next. Select Browse..., enter /extras/google/google_play_services/libproject/google-play-services_lib, and click Finish.
