Android版Google地图。 无法加载地图。 无法联系Google服务器

Question

I'm trying to work with Google Maps on my Android but where it should appear the map is white and I get the error: Failed to load map. Error contacting google servers. I've followed many tutorials and all the answers related on that problem but I still can't fix it. I think I have the correct API key (Google Maps for Android) and permissions, but perhaps I forget something and somebody could help me. My Android version is 4.1.1. Thanks a lot.

The AndroidManifest.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.mapmap"

    <uses-sdk

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true"/>

    <permission

            <activity
                android:name="com.example.mapmap.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>

The activity_main.xml:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.google.android.gms.maps.MapFragment"/>

The MainActivity.java:

package com.example.mapmap;
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);
}
}
