Attempting to Pack a UE4.27.2 build to test on Android 14 - PackagingResults: Error: Launch failed! Unknown Error

[BetaUltra]

I’m attempting to build my first mobile game project, and have run into a few hiccups in the setup process:
I am building a mobile game on UE 4.27.2, and the primary device I am looking to initially test on is a Galaxy S24 Ultra, running Android 14.
Setting up Android’s SDK tools, I have the following versions installed and used by the project:
Android SDK - API Level 34
Android NDK - API Level 21
I also have Android Studio Version 4.0 installed with both Android SDK Build 34.0.0, and 30.0.3 installed.

Regardless of what combination I try, or what solution I find online to the issues I’m having, I always end up with the same error:

LogPlayLevel: Execution failed for task ':app:processDebugResources'.

Android 14 (SDK 34) builds are required to specify a flag to indicate whether the receiver should be exported to all other apps on the device: either RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED, respectively. This changes, however, require minimum NDK r25, which aren’t currently supported in 4.27 nor 4.27Plus. A workaround is to define the flag literal value in the Engine/Build/Android/Java/src/com/epicgames/ue4/GameActivity.java.template:532:

+	private static int RECEIVER_EXPORTED = 2;
	@Override
	public void onStart()
	{
		super.onStart();
		
		if (!BuildConfiguration.equals("Shipping"))
		{
			// Create console command broadcast listener
			Log.debug( "Creating console command broadcast listener");
			consoleCmdReceiver = new ConsoleCmdReceiver(this);
-			registerReceiver(consoleCmdReceiver, new IntentFilter(Intent.ACTION_RUN));
+			registerReceiver(consoleCmdReceiver, new IntentFilter(Intent.ACTION_RUN), RECEIVER_EXPORTED);
		}
//$${gameActivityOnStartAdditions}$$
		Log.debug("==================================> Inside onStart function in GameActivity");
	}

Another important thing to do is to set these parameters in your project’s Config/DefaultEngine.ini:

[/Script/AndroidRuntimeSettings.AndroidRuntimeSettings]
TargetSDKVersion=34
bBuildForArm64=True
bBuildForArmV7=False
SDKAPILevelOverride=matchndk
NDKAPILevelOverride=latest
+ExtraActivityNodeTags=android:exported="true"
bShowLaunchImage=False
bSupportAdMob=False
bPackageDataInsideApk=True

Use NDK r23 (23.0.7599858) and JDK 11 in the SDK setting.
