title: Continuing problems running Android Apps
body: <p>I have been having a very difficult time with android apps. I'm using Eclipse, V 4.2.0, and running API version 7. Below is the LogCat output of one program I'm having difficulties.  This is my code:</p>
  
  <p>Manifest</p>
  
  <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"

          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  &lt;/application&gt;
  
  &lt;/manifest&gt;
