我正在尝试编写一些使用 Google Maps API 的应用程序。该地图显示在主要活动中。

在某些手机上，包括模拟器，应用程序在启动后立即崩溃。它唯一可以使用的手机是我的 Galaxy S1，它运行 CM10.1 (4.2.2)。

它在我的 HTC DESIRE HD（4.2.2 以及）上崩溃

只需执行以下操作即可检查 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 下载它们

听起来您正在测试的手机似乎没有安装最新的 Google Play Services pre-req。

如果您看一下这里，您会发现一个部分讨论如何确保设备安装了 google play 服务 APK，如果没有，请指导用户安装它。

另请注意，运行低于 Andorid 4.2.2 的 API 平台的模拟器不支持该模拟器（在第一节中引用）

我的应用程序也有同样的例外：

java.lang.NullPointerException: IBitmapDescriptorFactory is not initialized

就我而言，我必须BitmapDescriptorFactory在初始化 Google Map 对象后调用静态方法。

阅读评论：

// 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)
    ... some code ...
}

GoogleApiAvailability googleApiAvailability=GoogleApiAvailability.getInstance();

int status=googleApiAvailability.isGooglePlayServicesAvailable(getActivity());

        if (status != ConnectionResult.SUCCESS) {
            int requestCode = 10;
            Dialog dialog = googleApiAvailability.getErrorDialog(getActivity(),status,requestCode);
            dialog.show();
        }else{}

请参阅此处以检查您的手机上是否有可用的 Google Play 服务。如果您遇到错误，则会显示从 Google Play 服务返回的错误对话框。我已经在三星 Galaxy S3 上使用 Google Maps v2 开发了我的应用程序，并且运行良好。
