Error APT2259: '50%' is incompatible with attribute height (attr) dimension

Question

I receive this error when I try to specify a percentage on my splash-screen.xml:

error APT2259: '50%' is incompatible with attribute height (attr) dimension.

I want the screen to be splitted by two colors. My code is the following:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:height="50%" android:gravity="fill_horizontal|top">
    <color android:color="@color/yellow"/>
  </item>
  
  <item android:height="50%" android:gravity="fill_horizontal|bottom">
    <color android:color="@color/red"/>
  </item>
</layer-list>

How could I achieve this? Thank you so much for your help.

In android is not posible to specify a percentage (%) as a value. You have to specify a value in sp.

Take a look at the Dimensions documentation:
