根据1发布的代码可用于 Android API 12 或更高版本。我在具有 API 级别 10（Google API 平台 2.3.3）的模拟器上尝试了代码，我得到了以下著名的错误：

E/AndroidRuntime( 429): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example..../com.example....MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

我在下面复制粘贴我的 .xml 文件。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

所以我假设不支持片段元素......（？）。我在具有 API 级别 17 的模拟器中尝试了相同的代码，并收到了该消息（正如我正在阅读的那样，当前是模拟器的问题）：

This app won't run unless you update Google Play Services.

我没有真正的 17 级设备来测试它，但我认为它可能会工作。

我在上面的代码中是否有任何错误，专门针对 10 级？为了在 API 级别 10 的 Android 设备中开发地图，Google 当前支持的代码是什么？

更新：更改为后FragmentActivity，SupportMapFragment我得到以下信息：

2秒后：
Google Maps Android API Authorization failure

更新 2：我将项目更改为为 android 10 构建目标（我为 android 4.2 设置了它）。所以现在我没有看到授权失败）。我还粘贴了来自 google 的 api 访问api访问。

我没有在项目的 .properties 中启用 proguard，即：
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home): #proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.

而不是使用com.google.android.gms.maps.MapFragmentusecom.google.android.gms.maps.SupportMapFragment和 for ，Activity它必须切换到FragmentActivity下面的评论中提到的

我使用下面的代码希望对你有用：-

打包和扩展

import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class UserLocation extends FragmentActivity

代码

    android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
    SupportMapFragment mapFragment = (SupportMapFragment) fragmentManager
            .findFragmentById(R.id.map);
    googleMap = mapFragment.getMap();

为我工作。

支持MapFragment

对于早期的 API，您需要使用SupportmapFragment. 请参阅SupportMapFragment 文档，基本上使用class="com.google.android.gms.maps.SupportMapFragment"而不是class="com.google.android.gms.maps.MapFragment"

{将此用作代码的参考.. http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/

同样在上面的示例中，必须在清单的元数据标记中使用他自己的 Api Key 来生成 Api 密钥。}

现在如果你想在 android 2.3 中实现这个代码

1）首先更改清单

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="17" />

然后右键单击>属性>Android>Android 2.3

2）有两个google play服务库

   a)..\sdk\extras\google\google_play_services_froyo\libproject\google-play-services_lib

   b)..\sdk\extras\google\google_play_services\libproject\google-play-services_lib

如果您正在使用 android 2.3 ，请尝试将第一个 a 作为库项目 （您首先需要将其作为库项目导入文件>导入>...... )

3）然后按照此处的说明进行操作

4) 确保您的 Google Play 服务应用在您的设备上是最新的
