MAUI: Splash screen with 2 logos

Question

I am trying to create a splash screen with 2 logos, one on the sender and one as a footer. But I didn't get such type of implementation in MAUI. Is there any way to do it on MAUI?

So I tried platform level integration like below for android.

Created splash_screen.xml under Platforms/Android/Resources/layout folder.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/icon1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:src="@drawable/icon1" />

    <ImageView
        android:id="@+id/icon2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/icon1"
        android:layout_centerHorizontal="true"
        android:src="@drawable/icon2" />
</RelativeLayout>

Added icon1 and icone2 under Platforms/Android/Resources/drawable folder.

Added theme on AndroidManifest file under application tag.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application 
        android:allowBackup="true" 
        android:icon="@mipmap/appicon" 
        android:roundIcon="@mipmap/appicon_round" 
        android:supportsRtl="true"
        android:theme="@style/SplashTheme">
    </application>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
</manifest> 

Added styles.xml file under Platforms/Android/Resources/values folder and added below code.

<resources>
    <!-- Splash screen theme -->
    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@layout/splash_screen</item>
    </style>
</resources>

Finally on the MainActivity added below code:

public class MainActivity : MauiAppCompatActivity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);

        // Set the custom splash screen layout
        SetContentView(Resource.Layout.splash_screen);
    }
}

While running I getting the below exception:

Java.Lang.IllegalArgumentException: 'No view found for id 0x7f08014b (com.companyname.marianconsecration:id/navigationlayout_content) for fragment NavigationRootManager_ElementBasedFragment{f1d86d4} (a90f9cb5-b73f-4ac2-9767-c8bb9b057cb7 id=0x7f08014b)'

Hello,

For android 12, android use the SplashScreen Api to show the splash screen. It only customizes these parts: icon, window background, exit animation.

Creating custom layout and setting SetContentView(Resource.Layout.splash_screen); as the splash Screen is deprecated in android.

If you want to add a splashscreen in MAUI, you can refer to this document: Add a splash screen to a .NET MAUI app project

By the way, duplicated thread in SO https://stackoverflow.com/questions/78952510/splash-screen-with-2-logos

Try this:

1. Make styles.xml Build Action AndroidResource
2. In AndroidManifest.xml in the <manifest> tag added this lines of code:xmlns:tools="http://schemas.android.com/tools" android:theme="@style/AppTheme" tools:replace="android:theme"
3. In MainActivity.cs replace the Theme attribute property like this: [Activity(Theme = "@style/AppTheme"....)]
