UE5 Android crash in splash screen

HongyuShen · April 13, 2022, 3:24am

Hi, I converted my project from UE5 Early Access to UE5.0, and ran into the crashing problem. It worked fine before, I used UE5 EA to package Android, iOS, Windows and Mac, and all succeeded.

Now I have tried UE5.0 Windows and Android packaging, Windows is fine but not for Android. I don’t have an Android phone, so I uploaded it to Firebase Test Lab, it showed the splash screen for 1 second then crashed. I created an empty project and package, still has the same issue.

Engine version: UE5.0 on Windows 11

Android version: Pixel 3(API level 28), Pixel 5e(API level 30)

Project settings:

Java version: 1.8.0_301
NDK API level: android-21

I believe the issues is not from the JRE/SDK/NDK setup, because it worked fine in UE5 EA with the same settings.

Result on Firebase:

I am not sure why caused that. The first line said “release-keys”, does it mean missing keystore file? I set that up but still not working. Neither development build nor distribution build worked. It also mentioned “ABI: arm64”, but I didn’t enable ABI spliting at all, even enabling it doesn’t get better.

In project settings, neither “Generate bundle(AAB) + Generate universal APK from bundle” nor deselecting AAB worked. And I cannot untick “Support arm64[aka arm64-v8a]”.

If AAB is not selected, it generates:

AFS_-AppName-Shipping-arm64.apk
AppName-Android-Shipping.aab
AppName-Android-Shipping_universal.apk

If AAB is selected, it generates one extra file:

AppName-Android-Shipping-arm64.apk

Uploading .aab or .apk to Firebase have the same issue. The splitting options confuse me, since Firebase allows to upload only one file, I don’t want to split. I believe AAB is for distribution and APK is for testing, splitting is used for reducing app size and targeting devices with different architecture. I also tried disabling “Share Material Shader Code” and “Shared Material Native Libraries” in Packaging, but didn’t solve it.

I would be glad if anyone can provide some solution.

Now I am more convinced it is from the engine. I used UE4.27.2 to create an empty project, then packaged using the same settings. It worked fine. Both 4.27 and 5 EA work.

HongyuShen · April 19, 2022, 7:01pm

I tried 5.0.1, still has the same problem.

Same problem here. UE5.0.1 from the epic launcher, Huawei P40Pro+, Mi10T crashes at start.
I have create a blank C++ project, tried to run on device and it crashes

I have found a workaround for now.
Issue come from version of Android SDK and NDK installed on the machine.

I had a recent ones before, so I had to install android sdk ver 28(Pie) and android NDK version 21.4, Cmake was downgraded to 3.10 ( just in case )

Project settings / Android SDK been configured to use SDK API Level value as matchsdk and NDK API Level as latest

After than I been able to package, install and run the binary on a phone.

Hope it helps.

After that it

That’s a good sign. I tried that but didn’t work for me. I will just leave it and see whether it will get fixed in newer version.

And did you encounter a low frame rate issue? That’s also a serious thing. I posted here: UE5.0.1 low frame rate issue

Mnghwa · April 29, 2022, 10:27pm

same here. Win 10 Pro + UE 5.01
Android Pixel 3 (28)
With having Intro video i get this Firebase result:

After remove intro video I get this Firebase result:

Surprisingly, it works on Pixel 5e (30).

I heard that the requirement for Android in official UE5.0 is very strict, must be 64-bit and Android 8.0 Oreo or newer. Not all phones with API level 28 can run, I doubt that. I even tried to set the minimum to be API level 30.

But in UE5 Early Access is not that strict, I have been using it since its launch. Some exceptional phones like HTC 10(API level 26) can run.

Same issue here:

A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 25607

If the problem is an incompatibility between the packaged app and the target device/Android version, I would expect a better and more user friendly error handling by Android (and maybe also by UE5). This seems more an SDK/NDK problem with UE5 to me.

Kafumanto · May 10, 2022, 1:57pm

As expected, I solved installing specific versions of the Android SDK and NDK tools (as also already pointed out by @denton85 in the thread).

Using the SDK Manager of Android Studio, I ensured to have installed the NDK v21.4.7075529.
Then configured the Editor as follow:

Good to know.

anonymous_user_a0ffb2de · July 22, 2022, 3:45am

Had the same problem here in UE5.0.3 and changing Android SDK config didn’t work for me.
Yet the crash log specifically points to Vulkan API. I switched to using only OpenGLES and it worked on my Phone.
