Packaging for Android-"Failed" error

[Alex_Summers]

Hi, I’m trying to export my Crypt Raider project to Android, but I’m getting an error when building.
After clicking Platforms->Android->Package Project

I get this error:

After I click Continue, my output log shows this:

UATHelper: Packaging (Android (ASTC)): ERROR: Command E:\EpicGames\UE_5.2\Engine\Extras\Android\SetupAndroid.bat android-32 30.0.3 3.10.2.4988404 25.1.8937393 -noninteractive failed [Exit code 4, working dir = E:\EpicGames\UE_5.2\Engine\Extras\Android]

It looks like there’s some error with installing Android SDK r25b, but based on the first screenshot isn’t it already installed? Am I supposed to install the AutoSDK somehow?
I’m using UE 5.2.

How have you gone about installing the SDK?

I installed it through Android Studio by following the guide here.

I have since looked through the Crypt Raider Project Settings, and I noticed that the “Location of Android NDK” was set to the wrong directory – it should be in “ AppData/Android/Sdk/ndk/25.1.8937393 ”, and I had it above in the NDK folder (if anyone else is having trouble, you can install that NDK in Android Studio through the SDK Manager, and it has to be that one for UE5 to work correctly – see the above guide; version 25.1.8937393 corresponds to NDK r25b).

Setting up UE5 with the correct NDK location resulted in a successful build.
