Question

在按照this link的建议尝试使用google maps v2进行应用时，我开始了解获取密钥的过程，然后按procedure 导入google play服务。但是当我导入库时在我的项目中，我发现R文件丢失了。任何人都可以建议如何解决这个错误。

编辑

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 FIle：

<?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
        android:glEsVersion="0x00020000"

Answer 1

重新启动项目，运行清理并重建项目。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。

Answer 2

问题可能就是这个问题。

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)

因为我认为你已经使用过了。

<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"/>

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。您还可以在他们使用SupportMapFragment的Google地图演示中看到它。

在android项目中导入Google-Play-Services会删除R文件
