@jorge-cab @joevilches Can you have a look at this?

[nohabean]

@Titozzz The cause of this is because the default padding for Android is 3dp, so the padding is being overridden to the default once the outline is applied. This is why you have the padding initially but then when you remove focus (removing the outline) then re-focus (applying the outline), the padding is defaulted back to 3dp.

I can work to resolve this. @Titozzz or @cipolleschi, can I be assigned to this issue?

[cipolleschi]

@nohabean sorry for the late reply, we have been quite busy preparing AppJS when you posted. 😅

I assigned you to the issue. Feel free to open a PR and tag me when it is ready!
