java Google Maps API Android错误膨胀类片段

1 月，3 周 Questions & Answers 2247

我知道关于StackOverFlow这个问题有很多话题，但是没有一个能帮到我。我正在做一个非常基本的应用程序，我只想显示一张地图

我已经将google-play-services_库导入到我的主项目中
我已经生成了我的API密钥

这是我的AndroidManifest。xml文件：

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    package="com.linkme2night"
    安卓:versionCode="1"
    安卓:versionName="1.0" >

            安卓:label="@string/app_name" >
            <intent-filter>
                <action 安卓:name="安卓.intent.action.MAIN" />

                <category 安卓:name="安卓.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            安卓:name="com.google.安卓.maps.v2.API_KEY"
            安卓:value="AIzaSyBJVHZJr1Q14fcvEHBkAUT1A_ZH4eQlnrI" />
    </application>

</manifest>

这是我的布局XML文件：

<fragment xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    xmlns:map="http://schemas.安卓.com/apk/res-auto"
    安卓:id="@+id/the_map"
    安卓:name="com.google.安卓.gms.maps.SupportMapFragment "
    安卓:layout_width="match_parent"
    安卓:layout_height="match_parent" />

这是我的代码：

public class OpenVenuesMapActivity extends FragmentActivity  {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_open_venues_map);
    }
}

我正在Sony XPeria J上运行该应用程序。Loc Cat生成以下错误：

这是我从现有代码创建google服务库时得到的结果，这些代码位于我的C:/Program Files/eclipse/SDK/，然后将其导入到我的项目中：

error loading lib???

有人知道我还能错过什么吗？我开始对这件简单的事情感到绝望

I Have imported the google-play-services_lib to my main project.

不是根据你的堆栈跟踪。堆栈跟踪表明您手动修改了构建路径，以包含Play Services SDK中的JAR，而不是将Play Services SDK作为Android库项目附加
# 2 楼答案
你的最小sdk是11。您需要为低于12的api版本添加支持库
```
    <uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="17" />
```
碎片被引入蜂巢。所以，为了向后兼容，您需要添加支持库
```
 android:name="com.google.android.gms.maps.SupportMapFragment "
```
因为您没有添加支持库，所以得到了classcastexception

要添加支持库，请查看下面的链接

有 Java 编程相关的问题?
