title: running lint on ant app gives manifest error
body: <p>I have the following manifest:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest package="com.example.mfc"
      android:versionCode="1"
      android:versionName="1.0" xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;uses-sdk
          android:minSdkVersion="9"
          android:targetSdkVersion="17" /&gt;
     &lt;uses-permission android:name="android.permission.INTERNET"&gt;&lt;/uses-permission&gt;
      &lt;application  android:label="@string/app_name"&gt;
            &lt;activity android:name=".Home" android:label="@string/app_name"&gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.intent.action.MAIN" /&gt;
                  &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;/intent-filter&gt;
            &lt;/activity&gt;
     &lt;/application&gt;
  &lt;/manifest&gt;
  </code></pre>
  
  <p>But when running lint,i get a warning 'Correctness': 'The  com.example.mfc.Home is not registered in the manifest</p>
  
  <p>Issue: Ensures that Activities, Services and Content Providers are registered in the manifest
  Id: Registered</p>
  
  <p>Activities, services and content providers should be registered in the AndroidManifest.xml file using ,  and  tags.</p>
  
  <p>If your activity is simply a parent class intended to be subclassed by other "real" activities, make it an abstract class.</p>
  
  <p>[http://developer.android.com/guide/topics/manifest/manifest-intro.html]'</p>
  
  <p>Whilst it is,and i have the class Home extending Activity:</p>

          } catch(IOException ioEx) {
              ioEx.printStackTrace(); // or what ever you want to do with it

  <p>I am also getting an error when trying to run the project,'android library projects cannot be launched'.Is it related to the manifest?</p>
