Solution

You can read the developer documentation as this is a very broad question.

Most important step is to mention this in your application tag in the Android Manifest. android:supportsRtl="true". This works with Android 17 and above. For older versions, you need to programatically handle this.

Please check this link for the RTL Logic and changes you need to do for the app to function in the RTL mode.

On Android 4.4 (API level 19) and higher, you can use android:autoMirrored="true" when defining your drawable, which allows the system to handle RTL layout mirroring for you.

You can also set the layout direction like this:

val config: Configuration = context.resources.configuration
view.layoutDirection = config.layoutDirection
