Hi, I started to study the engine and immediately ran into such a headache. The application does not work in full screen mode.

Guided by [this information][1] added an additional tag to gameactivity - android:maxAspectRatio=“2.4”

Here’s more information on how to do it:

After some digging, I found this setting under Platforms → Android → APK Packaging, there is a setting called Use Display cut-out region? which includes the notch on top of the screen. Seems to be false by default.

usecutoutregion

Haven’t been able to test this just yet, but felt this might solve both our issues :')

Yes it’s good.

I need check:

  • Enabled “use cutout region?” in project settings
  • Disabled Launch image in Project settings
  • Changed “Maximum supported aspect ratio” from 2.1 to 5.0

Hi, this can be fixed in a C++ project. First of all, go to the Source/PROJECT_NAME folder and create the CustomAndroidManifest.xml file with the following code inside:

<?xml version="1.0" encoding="utf-8"?>
<root xmlns:android="http://schemas.android.com/apk/res/android">
    <androidManifestUpdates>
        <removePermission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        <removePermission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

        <loopElements tag="activity">
            <setStringFromAttribute result="activityName" tag="$" name="android:name"/>
            <setBoolIsEqual result="isTargetActivity" arg1="$S(activityName)" arg2="com.epicgames.unreal.GameActivity"/>
            <if condition="isTargetActivity">
                <true>
                    <addAttribute tag="$" name="android:maxAspectRatio" value="2.8"/>
                </true>
            </if>
        </loopElements>
    </androidManifestUpdates>
</root>

Then go to the PROJECT_NAME.Build.cs file and add the following code:

if (Target.Platform == UnrealTargetPlatform.Android)
{
    var manifestFile = Path.Combine(ModuleDirectory, "CustomAndroidManifest.xml");
    AdditionalPropertiesForReceipt.Add("AndroidPlugin", manifestFile);
}

This worked for me in UE 5.5.1
