Use Splash Screen and Avoid Flicker

This is just a TLDR version of this post.

Step 1

Put this in your android/res/drawable folder

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <shape android:shape="rectangle" >
            <solid android:color="#FFFFFFFF"/>
         <bitmap android:src="@drawable/icon"
        android:gravity="center" />

You can optionally use this. It does the same thing, but in this case you need to have a android/drawable/colors.xml file with the color blue defined in it.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/blue"/>
        <bitmap android:gravity="center" android:src="@drawable/logo"/>

Step 2

Create an app theme in android/res/values.

<?xml version="1.0" encoding="utf-8"?>
    <style name="AppTheme" parent="@android:style/Theme.DeviceDefault.Light.NoActionBar">
        <item name="android:windowBackground">@drawable/splash</item>

Step 3

Add this to your main activity in AndroidManifest.xml


Step 4

Set android.app.splash_screen_drawable to your splash drawable.

<meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>

Step 5

Use Loader to load your main scene. Set the initial opacity of the Loader to 0, and set the visible property of your Window to false. Loader should also have asynchronous: true. Like so:

Window {
    id: mainWindow
    visible: false

    Loader {
        anchors.fill: parent
        asynchronous: true
        opacity: 0
        onStatusChanged: {
            if (status === Loader.Ready) {
                mainWindow.visible = true;
                ldMain.opacity = 1;

        Behavior on opacity { NumberAnimation { duration: 150 } }

Step 6

You are done!


The only problem I encountered is that the splash screen that is shown before android.app.splash_screen_drawable is mis-aligned with the one show in android.app.splash_screen_drawable. To work around this problem I used the same style as the splash.xml but I removed the logo in the middle.
