試圖獲取地圖V2的Android演示工作

Question

新到Android等

所以我建議這個演示： http://dj-android.blogspot.in/2013/02/android-google-map-v2-part-1.html

我跟着它的事，但一定是出了問題。

...

• 在工作區我有我自己的項目：
• 這裏面的項目：在 「利布斯」 我已經加入 「Android的支持，v4.jar」
• 內這個項目：在Android Depencides我有「android-support-v4.jar」
• 在這個項目裏面：在參考資料庫我有「google-play-services.jar」
• 這個項目裏面：In參考ES圖書館我有 「Android的支持，v4.jar」

...

• 在工作區我有谷歌，播放services_lib作爲一個項目：
• 裏面這個項目：在「Libs」中我有「google-play-services.jar」
• 這個項目裏面：在「Libs」中我有「google-play-services.jar.properties」
• 這個項目裏面：在「Android Dependencies 「我有」google-play-services.ja R」

...

當我運行上面的SGII V4.1.2項目，我得到黑屏，隨後crasj如下錯誤：

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 
    android:id="@+id/fragment1" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.SupportMapFragment" /> 
</RelativeLayout> 

MainActivity.Java

package com.example.mapstest; 

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

    public class MainActivity extends FragmentActivity { 
     @Override 
     protected void onCreate(Bundle arg0) { 
      // TODO Auto-generated method stub 
      super.onCreate(arg0); 
      setContentView(R.layout.activity_main); 
     } 
    }  

注1：

難道你們相信的也可以是相關的以某種方式API密鑰的問題嗎？我用這個作爲API密鑰：

HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH:HH;com.exampledomain.exampleproject 

• 通知的結局。那是對的嗎？
• 我不得不編輯keytool的輸出，所以不能100％確定API密鑰是好的。請參閱： Maps v2 API Key on Android

注2：

我的當前配置的一些截圖：

如果你認爲我的問題的原因是，谷歌播放服務沒有正確安裝，我爲此創建了一個單獨的SO：Can not install google-play-services into Eclipse correctly (trying to get maps working)

Answer 1

試試這個：

這是一個博客帖子我在創建一個谷歌地圖API V2寫道。

UPDATE：

我拍了一張照片從我工作的地圖項目。忽略崩潰報告服務庫如acra，flurry，bugsense和crittercism。那麼你的項目看起來是一樣的嗎？

你有google-play-services_lib.jar在你的Android依賴關係文件夾？

Answer 2

In References Libraries I have added "google-play-services.jar"

這是不正確的。請刪除。然後，將Play Services Android庫項目導入到Eclipse環境中，並將其附加到您的項目中。

報價the documentation：

Copy the /extras/google/google_play_services/libproject/google-play-services_lib library project into the source tree where you maintain your Android app projects. If you are using Eclipse, import the library project into your workspace. Click File > Import, select Android > Existing Android Code into Workspace, and browse to the copy of the library project to import it.

To set up a project to use the Google Play services SDK... Reference the library project in your Android project. See the Referencing a Library Project for Eclipse or Referencing a Library Project on the Command Line for more information on how to do this.
