谷歌地圖使用supportmapfragment

Question

Android的API V2我試圖安裝項目目前在tutorial：

所有這沒關係，但跑項目時，logcat的說：

「找不到類‘maps.ag.l’從方法maps.ah.an.a引用「

地圖是空的，logcat的說：

」無法加載地圖錯誤聯繫谷歌服務器，這可能是一個身份驗證問題（但可能是由於。到網絡錯誤）

我已經將包名從「in.wptrafficanalyzer.locationgooglemapv2demo」更改爲「it.appatwork」，並且我已經獲得了用於我的sha1的android maps apiV2的apikey。

我有機器人2.3.3

請幫幫我！

Mainactivity：

package it.appatwork.locationgooglemapv2demo;

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

import com.google.android.gms.common.ConnectionResult; 
import com.google.android.gms.common.GooglePlayServicesUtil; 

public class MainActivity extends FragmentActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable (getApplicationContext()); 
    if(status == ConnectionResult.SUCCESS) { 
     System.out.println("ok"); 
    } 

} 

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

} 

activity_main.xml中：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".MainActivity" > 

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

AndoridManifest.xml：

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

UPDATE：

這是logcat的輸出：

Answer 1

的所有兩個問題，首先，你所描述是不相關的另一個人，你主要的問題是在這裏：

無法加載地圖。聯繫Google服務器時出錯。這可能是 身份驗證問題（但可能是由於網絡錯誤）。

這意味着您對清單文件中的權限或Google API控制檯中的配置有一些問題。

請仔細閱讀這兩篇博文的所有步驟，Google Maps API V2 key和Google Maps API V2，並提交所有步驟，如果您在此處發佈問題或更新logcat消息時仍有問題。

UPDATE：

你包的名字：

package="it.appatwork.locationgooglemapv2demo" 

不符合您在權限中指定的軟件包名稱：

permission 
     android:name="it.appatwork.LocationGoogleMapV2Demo.permission.MAPS_RECEIVE" 
     android:protectionLevel="signature"/> 

<uses-permission android:name="it.appatwork.LocationGoogleMapV2Demo.permission.MAPS_RECEIVE"/> 

我認爲這是區分大小寫，因此嘗試將其更改爲：

permission 
     android:name="it.appatwork.locationgooglemapv2demo.permission.MAPS_RECEIVE" 
     android:protectionLevel="signature"/> 

<uses-permission android:name="it.appatwork.locationgooglemapv2demo.permission.MAPS_RECEIVE"/>
