title: How to avoid Black Screen on starting an application
body: <p>When I start my application initially, I get a black screen which stays for a few seconds before my main activity starts. In case of iphone an image with name default is displayed for that split second. I'm not sure how to do the same in Android. I tried as below in vain :</p>
  
  <pre><code>         &lt;activity android:name=".Index"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@drawable/defaultimage"&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;  
  </code></pre>
