Support RTL for only one specific language

I have an app with translations in English and Arabic, so I go with android:supportsRtl="true" in AndroidManifest.xml.
The problem is that some users are using some RTL languages out of Arabic that has no translation in my app, e.g. Hebrew, so it shows the English translation with RTL.

How can I avoid that and keep RTL support only when the language is Arabic and other RTL languages' users will get the English translation with LTR?

Programatically, you can alter the layout direction for some languages.

if (lang in listOf(...)) 
    theView.layoutDirection = Layout.DIR_RIGHT_TO_LEFT

Or, you can use android:layoutDirection attribute.

some_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    
    android:layoutDirection="@integer/viewDirection"

    ...

Define default viewDirection in values/viewDirection.xml.

<integer name="viewDirection">0</string>
// 0 is for left to right

And also in the rtl language resource folder

values-ar/viewDirection.xml

<integer name="viewDirection">0</string>
// 1 is for right to left

You have to specify layout direction in all concerned views but some dialog's may still be in rtl mode.

It might be worth to check the documentation for LayoutInflater.Factory2.

Maybe, there is a much simplier way to solve this problem.
