我正在开发一个简单的应用程序来显示地图。为此，我将在真实设备上测试我的应用程序： Samsung Galaxy Europa（Android 2.2）。不幸的是我的应用程序被强制关闭/崩溃，在logcat中查看了很多错误（我提到了我的代码）。我按照规则包含了 google_play_services_lib ，但是徒劳无功。是的，我已经抓住了这里提到的所有解决方案，如：
但是，从其他许多解决方案中应用这些解决方案并没有实现。我的应用程序仍在崩溃。 我甚至在在线Manymo模拟器上测试了我的应用程序，但我的应用程序也在模拟器上崩溃了。 我的谷歌播放服务版本是不是让我的应用程序运行或其他什么原因？我将把我的代码和其他所有内容放在一起，这样你们就可以了解一下根本原因。

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GoogleMap googleMap;
googleMap = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(R.id.map))).getMap();
LatLng latLng = new LatLng(-33.796923, 150.922433);
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.addMarker(new MarkerOptions()
.position(latLng)
.title("My Spot")
.snippet("This is my spot!")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
// googleMap.getUiSettings().setCompassEnabled(true);
// googleMap.getUiSettings().setZoomControlsEnabled(true);
// googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 10));
}

答案 0 :(得分：2)
由于你的设备有2.2，你不能使用高于3.2的任何谷歌播放服务版本（我相信这是支持froyo停止的地方）。
您使用的是最新版本的Google Play服务，该服务不适用于2.2
您需要在SDK Manager中下载并使用Google Play Services for Froyo
