title: Application does not specify API level
body: <p>I am just beginning to use Eclipse for Android applications.
  I have installed Eclipse 3.5.2 and Java 5
  AVD is Android 2.1 API 7</p>
  
  <p>My initial Hello Android program ran fine but will not run again.</p>
  
  <p>getting the following error:</p>
  
  <blockquote>
    <p>[2010-07-25 09:47:31 - HelloAndroid] WARNING: Application does not specify an API level requirement!<br>
    [2010-07-25 09:47:31 - HelloAndroid] Device API version is 7 (Android 2.1-update1)</p>
  </blockquote>
  
  <p>searched the forums but could only find a refernece to manifest file to be sure following was set:</p>
  
  <pre><code>&lt;uses-sdk android:minSdkVersion="3" /&gt;
  </code></pre>
  
  <p>my manifest file does not contain that line:</p>
  
  <pre><code> &lt;?xml version="1.0" encoding="utf-8" ?&gt; 
   &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.helloandriod" android:versionCode="1" android:versionName="1.0"&gt;
       &lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt;
           &lt;activity android:name=".HelloAndroid" 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>
