Android谷歌地圖API v2

我正在開發一個使用谷歌地圖API V2的Android應用程序，應用程序崩潰，我有這個錯誤。Android谷歌地圖API v2

我可以用這個代碼公共類MainActivity擴展FragmentActivity {

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    SupportMapFragment fragment = new SupportMapFragment(); 
    getSupportFragmentManager().beginTransaction() 
      .add(android.R.id.content, fragment).commit();

}}

，但是當我嘗試添加標記與此代碼，應用程序崩潰顯示地圖

public class MainActivity extends FragmentActivity { 

     private GoogleMap mMap; 

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

     @Override 
     protected void onResume() { 
      super.onResume(); 
      setUpMapIfNeeded(); 
     } 

     private void setUpMapIfNeeded() { 

      if (mMap == null) { 

       mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) 
         .getMap(); 

       if (mMap != null) { 
        setUpMap(); 
       } 
      } 
     } 

     private void setUpMap() { 
      mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker")); 
     }

a ctivity_main.xml

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

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

你是做了錯誤的方式：

從活動佈局文件，你這樣做：

<?xml version="1.0" encoding="utf-8"?> 
<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.SupportMapFragment"/>

所以你定義在XML文件中的地圖片段。

從您要創建代碼映射片段的實例，並manualy加入它的另一方面：

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

所以基本上你兩次添加地圖碎片，它們沒有連接一個另一個。

你應該做的另一件事是刪除這一行：

<uses-library android:name="com.google.android.maps" />

這是一個API V1許可，並沒有任何與API V2。

我看到，但這是爲我工作，它崩潰時，我試圖添加一個標記（第二個代碼） – San

最後的解決方案工作對我來說thanx ^^ – San

@San，最後的解決方案爲你工作？ –

加入谷歌播放服務項目作爲一個庫而不是把jar文件裏面庫夾。

我試過了，但仍然有同樣的問題！ – San

進口谷歌播放-services_lib作爲一個項目，並在導入選擇複製到工作區

你添加了所有這些權限？

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> 
<!-- 
The following two permissions are not required to use 
Google Maps Android API v2, but are recommended.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

我已經做到了，但我仍然有同樣的錯誤！ – San

k你有沒有在庫中加入它？並且您需要將android-support-v4.jar添加到外部罐子中 – prvn

我在庫文件夾 – San

如果你的活動是由發射器發射的消息？片段需要默認初始值設定項。

嘗試按意向運行第二個活動。

試試看看這個代碼。

Intent intent = new Intent(this, [map activity].class); 
statrtActivity(intent);
