Splash screen narrowed inside

Question

I used an image as background of splash screen, it's been resized for different pixel densities:

hdpi - 480x800 mdpi - 320x480 xhdpi - 768x1280 xxhdpi- 1080x1920 xxxhdpi - 1440x2560

splash_screen.xml

<?xml version="1.0" encoding="utf-8"?>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" android:opacity="opaque">

    <item android:drawable="@drawable/launcher"/>

</layer-list>

styles.xml

    <style name="AppTheme.Launcher" parent="BaseAppTheme">
        <item name="android:windowBackground">@drawable/splash_screen</item>
        <item name="colorPrimaryDark">@color/grey_light</item>
    </style>

It works fine on emulator, however on Samsung Galaxy M20, A7, S9 etc (resolution 2340x1080, screen density xhdpi) it looks narrowed inside. Any solution for that?

Read official guideline about Support different pixel densities.

To provide good graphical qualities on devices with different pixel densities, you should provide multiple versions of each bitmap in your app—one for each density bucket, at a corresponding resolution.

drawable-ldpi        //240x320
drawable-mdpi        //320x480
drawable-hdpi        //480x800
drawable-xhdpi       //720x1280
drawable-xxhdpi      //1080X1920
drawable-xxxhdpi     //1440X2560

And add this in your manifest

 <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:resizeable="true"
        android:smallScreens="true"
        android:xlargeScreens="true" />
