我的应用程序已经在使用 Google Maps Android API v2，并且正在我的 Galaxy Mini (Android 2.3.6) 上运行。当我尝试在使用平台 4.0.3、API 级别 15 和 Google API 的模拟器上进行测试时，出现以下错误：

引发异常的行是这样的：

mMap.setInfoWindowAdapter(new MapInfoWindowAdapter(getLayoutInflater(savedInstanceState)));

MapInfoWindowAdapter 构造函数是这样的：

MapInfoWindowAdapter(LayoutInflater layoutInflater) {
        mLayoutInflater = layoutInflater;

        mWindow = mLayoutInflater.inflate(R.layout.map_info_window, null);
        mContents = mLayoutInflater.inflate(R.layout.map_info_window, null);
    }

map_info_window.xml 是：

你知道为什么它不工作吗？

根据 Google 的说法，Google Play 服务API 需要“物理开发设备”，因此它们不受模拟器的官方支持。因此，如果您在模拟器上运行，几乎可以肯定您缺少所需的服务。人们报告说让它在模拟器中工作，但我自己没有尝试过。如果您想在模拟器上安装 Google Play，您可以在这篇文章中查看答案。

当您尝试从您的 xml膨胀MapFragmentor时，您会收到错误消息。SupportMapFragment通过调用 检查设备是否具有 Google Play 服务通常是一个好主意isGooglePlayServicesAvailable()，并确保它ConnectionResult.SUCCESS在继续之前返回。这使您可以显示错误对话框，而不仅仅是崩溃。Google 甚至为其他一些代码提供了错误对话框，您可以通过 提示它们升级/安装getErrorDialog()，例如 --

int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
switch (resultCode) {
   case ConnectionResult.SUCCESS: // proceed
      break;
    case ConnectionResult.SERVICE_MISSING:
    case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
    case ConnectionResult.SERVICE_DISABLED:
          Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, this, 1);
          dialog.show();
 }

在调用之前执行此操作setContentView。
