SupportMapFragment未找到

Question

我正试图让Google，Android，v2，在Android2.2上工作，满足HTC的需求。

我的main.xml包含以下内容：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="dk.sw510e13.user"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="dk.sw510e13.user.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

这是我的活动。

package dk.sw510e13.user;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

public class MainActivity extends FragmentActivity {

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


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

当我运行应用程序时，我将得到以下异常。它似乎找不到SupportMapFragment，然而，我相信我同时拥有支持库和Google服务作为依赖项。在Android中创建项目时，我选择添加对片段的支持。

这就是我所依赖的东西。

有人能告诉我我做错了什么吗？

Answer 1

这就是当谷歌播放服务缺失时出现的问题。

我请求您按照下面提到的步骤，将Google服务包含在您的应用程序中。

在libs文件夹中复制google-play-services.jar并在eclipse的构建路径中设置是一个错误的方法。

1. 在项目中导入Google服务并将其添加到工作区中。从SDK文件夹的位置。

\extras\google\google_play_services\libproject\google-play-services_lib

2！现在您将Google服务添加到您的工作空间中，我们必须从我们的项目中创建一个对这个库的引用。右击您的项目并选择“Properties”转到Android部分，在下面部分按下“Add…”。按钮并添加对该库的引用。您的结果应该和下面的屏幕截图一样：

添加Google服务库

请添加
