title: intent-filter with android:priority setting
body: <p>I test the intent-filter <code>android:priority="0"</code> and intent-filter <code>android:priority="20"</code> by <code>android.intent.category.HOME</code>. I list the information below,</p>
  
  <pre><code>    &lt;activity android:name=".TestHomeActivity"
                android:label="@string/app_name"&gt;
          &lt;intent-filter android:priority="0"&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
              &lt;category android:name="android.intent.category.HOME" /&gt;
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;category android:name="android.intent.category.DEFAULT" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  </code></pre>
  
  <p>When finishing system booting, it always pops up a dialog (ResolveActiivty) for choose preferred activity for this intent...</p>
  
  <p>Can anyone can help this? is it error usage for <code>android:priority</code>?</p>
  
  <p>Thanks!</p>
