Android Alloy appicon and splash screen not working with android theme "Theme.NoTitleBar"

I am using Ti SDK 3.2.0 and alloy project for an android application. I am using android standard theme in my tiapp.xml.

My appicon.png and default.png files are present in app/assets/android/ folder I have also places default.png in app/assets/android/images/res-long-land-hdpi (and other density folders)

But when I run the app, appicon is default android icon. The splash screen is blank (black screen).

Below is my tiapp.xml configuration for android.

<icon>appicon.png</icon>
 
.....
 
 
<application android:hardwareAccelerated="true" >
                <!-- android:name needs to match the generated AndroidManifest.xml in build/android/AndroidManifest.xml -->
                <activity
                        android:name=".LegalinkActivity"
                        android:configChanges="keyboardHidden|orientation"
                        android:theme="@android:style/Theme.NoTitleBar">
 
                    <intent-filter>
                        <action android:name="android.intent.action.MAIN" />
                        <category android:name="android.intent.category.LAUNCHER" />
                    </intent-filter>
                </activity>
            </application>

Can one suggest why the appicon and splash screen is not picking up?
