Android 12 Splash Screen API not working with Material Component

Question

I've been following the documentation, but unfortunately it doesn't include the adaptation when using Material Component as app overall theme.

<style name="Theme.App" parent="Theme.MaterialComponents.DayNight">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryVariant">@color/colorPrimaryDark</item>
    <item name="colorOnPrimary">@android:color/white</item>
    <!-- Secondary brand color. -->
    <item name="colorSecondary">@color/colorPrimary</item> <!--Fab color-->
    <item name="colorOnSecondary">@color/colorAccent</item> <!--Fab icon color-->
    <item name="colorSecondaryVariant">@color/colorAccentDark</item>
    <!-- Status bar color. -->
    <item name="android:statusBarColor">?attr/colorPrimaryVariant</item>
    <!-- Customize your theme here. -->
    <!--<item name="tabStyle">@style/AppTabLayout</item>-->
    <!-- The color for all other text including the menu -->
    <item name="android:textColor">@color/colorPrimary</item>
    <item name="android:textColorHighlight">@color/colorAccentDark</item>
    <item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>

    <item name="checkboxStyle">@style/AppCheckBoxStyle</item>
    <item name="popupMenuBackground">@drawable/popup_bg_rounded</item>
    <item name="materialAlertDialogTheme">@style/AppDialogTheme</item>

    <item name="autoCompleteTextViewStyle">@style/AppCursor</item>

    <item name="overlapAnchor">false</item>
    <item name="android:dropDownVerticalOffset">?attr/actionBarSize</item>

    <item name="android:forceDarkAllowed" tools:targetApi="q">false</item>
</style>

<style name="Theme.App.Starting" parent="Theme.SplashScreen">
        <item name="windowSplashScreenBackground">
            @color/whitePrimaryDark
        </item>
        <item name="postSplashScreenTheme">
            @style/Theme.Cryptonian.NoActionBar
        </item>
    </style>

Android Manifest

    <activity
        android:name=".presentation.MainActivity"
        android:exported="true"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.App.Starting"
        android:windowSoftInputMode="adjustPan">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

It crash with an error

  Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.AppCompat (or a descendant).

Does anyone face same issue?

Are calling installSplashScreen() before setting layout content of your activity? Ref: developer.android.com/reference/androidx/core/splashscreen/… – Cichocki

Answer 1

The solution is to install the Splash Screen API before calling super.onCreate() and setContentView

Ide

In my case, calling it before super.onCreate() does not show splash screen. But calling it right after super.onCreate() and before anything else works fine – Markle

Answer 2

You need to change this:

<item name="postSplashScreenTheme">@style/Theme.Cryptonian.NoActionBar</item>

to this:

<item name="postSplashScreenTheme">@style/Theme.App</item>

postSplashScreenTheme requires to get you app theme. after showing splash screen your app theme wi

Sorry I already solved this and this is not the solution. Thanks anyway – Ide

Thanks, I don't know how I missed that even though it's in the documentation. It might not was the solution for OP, but it was indeed a solution for this error. – Edger
