我正在尝试做这个简单的教程（http://mobile.tutsplus.com/tutorials/android/android-sdk-working-with-google-maps-application-setup/），但是标题中提到了一个问题. 当我尝试在真实设备（Android 2.3.6）上运行此应用程序时，我的 LogCat 中出现以下错误：

我的 MainActivity.java：

package com.example.interestmapapp;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

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

}

我的 AndroidManifest.xml：

</manifest>

我的activity_main.xml

<fragment xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/the_map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    map:cameraTilt="45"
    map:cameraZoom="14" />

我已成功将我的 API 密钥添加到 Manifest，我还将 Google Play 服务导入到项目中（如教程所述）。有谁知道我该怎么办？谢谢你的帮助。

你的 min sdk 是 8。你应该使用SupportMapFragment.

<fragment
class="com.google.android.gms.maps.SupportMapFragment"
...

您的课程必须扩展FragmentActivity.

还要确保您导入了以下内容

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;
