java - 二进制 XML 文件行 #2 : Error inflating class

Question

我知道像这样的类似问题已经得到解答，但我似乎已经按照教程的建议进行操作并从其他帖子中阅读，但我仍然收到 Inflator 错误。不确定我做错了什么。我没有看到谷歌地图。请检查代码。非常感谢。

我生成我的 key :

keytool -list -v -keystore mystore.keystore

Activity_Map.java

package pt.example.project;

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

public class Activity_Map extends FragmentActivity {

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

文件xml.xml

Answer 1

    android:minSdkVersion="8"

您的最小 sdk 是 8，您需要添加支持库或将您的最小 sdk 设置为 12

使用 SupportFragment。

 android:name="com.google.android.gms.maps.SupportMapFragment"

引用文档

仅当您的目标是 API 12 及更高版本时才使用 MapFrament 类。否则，请使用 SupportMapFragment。
