Black screen before Splash screen appear in android
Its a duplicate question please check questions before posting
Add a theme with the background you are using to your application tag in the manifest file to prevent the black screen to be drawn.
<resources>
<!-- Base application theme is the default theme. -->
<style name="Theme" parent="android:style/Theme" />
<style name="Theme.MyAppTheme" parent="Theme">
<item name="android:windowNoTitle">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowBackground">@drawable/my_app_background</item>
</style>
</resources>
AndroidManifest.xml
....
<application
android:name="@string/app_name"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.MyAppTheme"
>
....
But you can only set an image or bgcolor here no custom Layout
