How to correctly show Arabic letters in Android?

Question

My application shows letters and words on arabic language. But these letters looks wrong. For example symbols بَ and شَ :

Correct (from iOS):

Wrong (from Android):

As you can see, the little line on the top of letters must be centered. But it's not. How to show Arabic symbols on Android like on iOS?

UPDATE: I am trying to use Better-Arabic-Shapper, but it's also displaying incorrectly:

Better-Arabic-Shapper

I am trying to set custom fonts (Arial, Simpo, nassim_latn_rg) with the code below but it also doesn't work correctly:

private const val FONT_PATH = "fonts/"

val font = "nassim_latn_rg.otf"
val typeface = Typeface.createFromAsset(context.assets, FONT_PATH + font)
textView.typeface = typeface

Answer 1

I tried with Roboto font, it works fine. All app settings are default. I did not have to add android:supportsRtl="true" in my manifest.

<style name="RobotoRegular">
    <item name="android:fontFamily">sans-serif</item>
</style>

Result:

Please try this font and revert if you still encounter the issue. I have a feeling this is a font-related issue.
