import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class MapsActivity extends FragmentActivity {
private GoogleMap mMap; // Might be null if Google Play services APK is not available.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
setUpMapIfNeeded();
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}
private void setUpMap() {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
}
What am I missing, what can be the problem? Any help much appreciated.

Got a solution. Had to do two things - set the Play Services version to lower: 5.0.89. The last version wasn't available for downloading from any (virtual) device I tested, required update.
得到了解决方案。必须做两件事 - 将播放服务版本设置为较低：5.0.89。无法从我测试的任何（虚拟）设备下载最新版本，需要更新。
Secondly, to install Google Play Services to Genymotion VM, followed instructions under this link: How to install Google Play Services in a Genymotion VM (with no drag and drop support)?.
其次，要将 Google Play 服务安装到 Genymotion VM，请按照此链接下的说明进行操作：如何在 Genymotion VM 中安装 Google Play 服务（不支持拖放）？.
Cheers.
干杯。

Another solution is to change the target of your emulator to the Google API
另一种解决方案是将模拟器的目标更改为 Google API
To test your app when using the Google Play services SDK, you must use The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher. Source
要在使用 Google Play 服务 SDK 时测试您的应用程序，您必须使用带有 AVD 的 Android 模拟器，该 AVD 运行基于 Android 4.2.2 或更高版本的 Google API 平台。 来源

Ojonugwa's solution is good but in addition there is an issue with the latest version of Google Play Services not being available on the emulator. However an appropriate version of Google Play Services is available on emulators running API version 21 or 19.
Ojonugwa 的解决方案很好，但此外还有一个问题是最新版本的 Google Play 服务在模拟器上不可用。但是，在运行 API 版本 21 或 19 的模拟器上可以使用适当版本的 Google Play 服务。
The current solution then is to create a new AVD with an API version of 21 or 19, and target Google APIs ( not Andriod x.x.x ). If you use a Google API AVD with API version 21 or 19 it should work as expected.
当前的解决方案是创建一个 API 版本为 21 或 19 的新 AVD，并针对 Google API（而不是 Andriod xxx）。如果您使用带有 API 版本 21 或 19 的 Google API AVD，它应该可以按预期工作。
