在尝试按照此链接的建议使用 google maps v2 进行应用程序时，我开始执行获取密钥的程序，然后按照导入 google play 服务的程序进行操作。但是当我在我的项目中导入库时，我发现 R 文件丢失了。谁能建议如何解决此错误。

代码和它的日志猫。

public class Maptest extends FragmentActivity {

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

XML 文件：

<?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"
  class="com.google.android.gms.maps.MapFragment"/>

然后是清单文件中给出的权限

<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

  <uses-feature

重新启动您的项目，运行干净并重建您的项目。如果问题仍然存在，请尝试检查其他文件中是否存在其他错误。如果问题仍然存在，请尝试编辑并保存 de AndroidManifest.xml。

问题可能是这个。

com.google.android.gms.maps.SupportMapFragment.onInflate(Unknown Source) 02-20 10:30:16.093: E/AndroidRuntime(21076): 
at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:271)

因为我觉得你用过。

<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.MapFragment"/>

它应该是。

 <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"/>

Google play 服务库使用 SupportMapFragment 而不是 MapFragment。您还可以在他们的谷歌地图演示中看到他们使用了 SupportMapFragment。
