听起来好像你正在测试的手机没有安装最新的Google Play Services pre-req 如果你看一看，你会发现一个章节讨论了如何确保设备安装了google play服务APK，如果没有，请指导用户安装
还请注意，运行API平台低于ANDROID 4.2.2（在第一节中引用）的仿真器不支持仿真器。请参阅检查手机上的Google Play服务。如果您遇到错误，它将显示一个从Google Play服务返回的错误对话框。我已经使用三星Galaxy S3上的Google Maps v2开发了我的应用程序，它工作正常。只需执行以下操作，检查Google play服务是否可用：
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if(status == ConnectionResult.SUCCESS) {
//Success! Do what you want
}else{
GooglePlayServicesUtil.getErrorDialog(status, this, status);
}
它将检查google play服务，如果不可用，它将提示用户从google play下载这些服务
java.lang.NullPointerException: IBitmapDescriptorFactory is not initialized
BitmapDescriptorFactory// This line initilizes the map asynchronously. It requires implementation
// of OnMapReadyCallback interface.
// And when it is inizilized, it calls onMapReady(GoogleMap googleMap)
mapFragment.getMapAsync(this);
// The following method is implemented in my activity
@Override
public void onMapReady(GoogleMap googleMap) {
... some code ...
currentLocationIcon = BitmapDescriptorFactory.fromResource(R.drawable.report_location_current)

}
是否启用了总账模式？GoogleMap2库是如何包含在您的项目中的？我刚刚导入了google服务：像那样：导入→ 安卓→ 将现有Android代码导入工作区。如何启用该GL模式？我没听说过。要启用GL模式，请将此代码放入AndroidManifest中，以便与google服务良好配合，您必须将整个google-play-services_库导入到您的类似项目的库中。如何实现这些方法？我需要添加一个库还是什么？因为它告诉我没有“isGooglePlayServicesAvailable（）；”之类的东西。例如，有没有其他方法可以使用地图并避免要求用户下载sdk？“isGooglePlayServicesAvailable（）”可以在com.google.android.gms.common中找到，如下所示：如果您将它添加到项目中，它应该是google Play Services库的一部分。如果没有，可以通过另一种方式在{SDK Dir}\extras\googleAs中找到它，不是真的，至少不是官方的。你也无法在游戏市场上搜索它，因为它是隐藏的。它不是SDK，而是Google Play Services APK，用户甚至需要使用最新的Google Maps v2实现，所以大多数用户应该已经拥有了它anyway@NirPes为了调用
