Android地圖V2應用程序在手機上崩潰

Question

我在我的手機（三星Galaxy S3，4.1.2）上使用我的應用程序，因爲人們提醒我說到android地圖v2應用程序，但我仍然在它的地方得到相同的錯誤說我的應用程序非常不情願地停了下來。

MainActivity.java

package com.example.name; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import com.google.android.gms.maps.SupportMapFragment; 

public class MainActivity extends FragmentActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     SupportMapFragment fragment = new SupportMapFragment(); 
     getSupportFragmentManager().beginTransaction() 
       .add(android.R.id.content, fragment).commit(); 
    } 
} 

的Manifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.name" 
    android:versionCode="1"

     android:debuggable="true" > 
     <activity

     </activity> 

     <meta-data 
      android:name="com.google.android.maps.v2.API_KEY" 
      android:value="**api_key**" /> 
    </application> 

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

</manifest> 

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/map" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment"/>

Answer 1

不知何故，你缺少的項目中的地圖V2庫中的代碼。您需要正確連接到表示Play Services SDK的Android庫項目。請參閱the Play Services documentation，特別是以「設置項目以使用Google Play服務SDK」開頭的部分。

Answer 2

我得到這個錯誤，當我進口Google_Play_Services_lib沒有檢查複製項目的選擇到工作區。看到畫面

還要檢查，我的日食我blogPost都試圖解釋的問題

Answer 3

如果您使用的是Google I/O之後推出的SDK工具v17，請檢查以下任何幫助：
