java.lang.IllegalArgumentException: This component requires that you specify a valid android:textAppearance attribute
Does your theme extend from Theme.MaterialComponents? More info about how to ensure all the components will work correctly can be found at https://material.io/develop/android/docs/getting-started/
If you are using any of the MaterialComponent, then your theme must extend from the following theme - Theme.MaterialComponents.Light.DarkActionBar
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar"> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item></style>
If you want to keep using your old styles but only want to extend from 'Theme.MaterialComponents' then you can use 'Bridge'.
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorAccent</item> <item name="colorAccent">@color/colorPrimaryDark</item></style>
