java - Android Google Map - 错误膨胀类 fragment

Question

我正在尝试在我的 Activity 上显示 GoogleMap。我已完成所有必要步骤，包括 key 生成、链接 google-play-services_lib、添加 android-support-v4.jar。但是由于 Fragment，我遇到了一个错误。我尝试了很多解决方案，花了很多时间但无法解决这个问题。请帮我。

MapActivity.java

package com.example.classified_android_app;

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

public class MapActivity extends FragmentActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);
    }
}

map .xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"
        map:cameraTargetLat="17.660324"
        map:cameraTargetLng="75.906601"
        map:cameraZoom="15" >
    </fragment>

</RelativeLayout>

Answer 1

主要问题是你的android:minSdkVersion="16"

What original docs said is

如果您的 android:minSdkVersion > 12那么你应该使用 MapFragment与扩展 Activity

和

如果您的 android:minSdkVersion < 12那么你应该使用 SupportMapFragment与扩展 FragmentActivity
