Issue: 1) When my application start then white/black screen appears, and then main UI is display. 2) Before my fragment load in activity black/white screen appears for 3/4 seconds and then fragment load. Solution: To fix this nasty problem, update the /res/values/styles.xml to include <item name="android:windowDisablePreview">true</item> or <item name="android:windowBackground">@android:color/black</item> for example : <!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <item name="android:windowDisablePreview">true</item> <!-- <item name="android:windowBackground">@android:color/black</item> --> </style>
