Bitmap Image is not sharpen

Question

I'm including a launch image for my android application in Flutter. However this image is either blurry or too big. When I view the image on my hard drive it is sharp. How can I keep the image sharp?

/res/drawable/launch_background.xml:

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/background" />

    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/icon_transparent_256" />
    </item>
</layer-list>

/res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
</resources>

current result: screenshot

actual image: logo

As @Michael Dougan pointed out, the image size was too small and instead of saving one version of the launch image in /res/drawable/ , it is better so save the image in different sizes (eg /res/mipmap-xxxhdpi )
