我的应用已经在使用谷歌地图Android API v2，它正在我的Galaxy Mini（Android 2.3.6）上运行。当我尝试使用Platform 4.0.3，API级别15和Google API在模拟器上进行测试时，会出现以下错误：

抛出异常的行是：
mMap.setInfoWindowAdapter(new MapInfoWindowAdapter(getLayoutInflater(savedInstanceState)));
MapInfoWindowAdapter构造函数如下：
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：

你知道它为什么不起作用吗？
答案 0 :(得分：0)
根据Google的说法，Google Play services API需要“物理开发设备”，因此仿真器不会正式支持它们。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。人们报告让它在模拟器中工作，但我没有尝试过自己。如果您想查看在模拟器上安装Google Play，可以查看this post中的答案。
当您尝试从xml中充气MapFragment或SupportMapFragment时出现错误。通常，最好通过调用isGooglePlayServicesAvailable()来检查设备是否具有Google Play服务，并确保在继续之前返回ConnectionResult.SUCCESS。这允许您呈现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getErrorDialog()提示他们升级/安装，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();
}
在致电setContentView之前执行此操作。
