Add this item to Your default AppTheme Style

<item name="android:windowDisablePreview">true</item>

Your Default base Style Will something like

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
  ...
    <item name="android:windowDisablePreview">true</item>
</style>

But I suggest you don't disable windowDisablePreview because it will disable your animations.

instead of above way you can change that white screen to your Application color theme by using this Style

<style name="StartUpTheme" parent="@android:style/Theme.Light.NoTitleBar.Fullscreen">
    <item name="android:windowBackground">@color/colorPrimary</item>
</style>

and use it in your Manifest file like

<application 
        ...

 <activity
            android:name="com.google.androids.MainActivity"
            android:label="@string/app_name"
            android:theme="@style/StartUpTheme">
        <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
</activity>
