title: How to change the launcher activity name and icon and keep the app name and icon?
body: <p>I would like to have different title bar icons and names in the different activities, but not to change the app name or icon. The first activity should not have a title name.</p>
  
  <p>This is what I have in the <code>AndroidManifest.xml</code>:</p>
  
  <pre><code>&lt;application
          android:allowBackup="true"
          android:icon="@mipmap/ic_launcher"
          android:label="@string/app_name"
          android:theme="@style/AppTheme" &gt;
          &lt;activity
              android:screenOrientation="portrait"
              android:name="" &lt;!-- there should be no title here --&gt;
              android:icon="@drawable/custom_icon"
              android:windowSoftInputMode="stateHidden|adjustResize" &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;activity
              android:screenOrientation="portrait"
              android:name=".MainActivity"
              android:icon="@drawable/another_custom_icon"
              android:label="MainTitle" &gt;
          &lt;/activity&gt;
  &lt;/application&gt;
  </code></pre>
  
  <p>Apparently <code>Android</code> uses the name and the icon of the first activity for the app name and icon.
  I know that I can put this line of code in the <code>onCreate</code> of the activity:</p>
  
  <pre><code>    getActionBar().setTitle("");
  </code></pre>
  
  <p>But it is also shown during load, until it gets removed.</p>
  
  <p>This is the <code>styles.xml</code> file:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="@android:style/Theme.Holo.Light"&gt;
      &lt;item name="android:actionBarStyle"&gt;@style/actionBarCustomization&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="actionBarCustomization" parent="@android:style/Widget.Holo.Light.ActionBar"&gt;
      &lt;item name="android:background"&gt;#FFFFFF&lt;/item&gt;
      &lt;item name="android:titleTextStyle"&gt;@style/actionBarTextColor&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="actionBarTextColor" parent="@android:style/TextAppearance"&gt;
      &lt;item name="android:textColor"&gt;#000000&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
