Updated to Oreo [Android] - Now Daydream App Crashing on Launch

I updated my pixel to Oreo, and now my daydream app crashes on launch.

I don’t quite know where to start when it comes to debugging this problem.

Any tips on where to get started?

Here is the relevant section of my adb logcat file:

There is an issue we are seeing with ARM64 and the Google Play Games C++ library. Updating from v2.1 to v2.3 fixed this for us and we are looking to include this update in 4.18 after more testing so won’t be in preview #1.

You can try updating your 4.17 by doing the following:

  1. Download v2.3 here: https://developers.google.com/games/services/downloads/gpg-cpp-sdk.v2.3.zip

  2. Unzip it in Engine/Source/ThirdParty/GooglePlay as gpg-cpp-sdk.v2.3

  3. Copy the GpgCppSDK.Build.cs from v2.1 into this directory and edit it to change the GPGAndroidPath from 2.1 to 2.3

  4. Delete the original gpg-cpp-sdk.v2.1

  5. Edit the Engine/Build/Android/Java/aar-imports.txt and change the versions to 11.0.4

  6. Edit OnlineSubsystemGoogle_UPL.xml and change the AARImports version inserted for play-services-auth to 11.0.4

  7. Run android.bat (just android in android-sdk-macosx/tools on Mac) and click “Deselect All”

  8. Scroll down to Extras and select Android Support Repository and Google Repository, then “Install 2 packages” to get the latest Google Player Services and support libraries needed

  9. Make sure your project Minimum SDK Version is at least 14 (required by new Google Play Services version)

Chris Backcock,

That works! Thank you.

I appreciate your time and effort.

4

Chris, does the problem effect blueprint only projects as well or only C++ projects? I’ve not been able to test with Oreo yet…

5

Yes, it happens during static initialization of the library linked into the libUE4.so so this affects BP and C++ projects.

I have tried what has been suggested there, but now I can’t even get my project to successfully build anymore.
I keep getting this error at the very end, during the final package preparation:

I’ve updated the SDK’s and extra files and such still busted.
Is there some other file I have to update too?
I noticed that in Step 3 my path was different, and I saw that there was an additional PublicIncludePaths to add. There was an armebai & an armeabi-v7a Is only one of these needed?

Here’s more detail on the Error log. The Android 7.0 & API Level 24 are suspicious, but donno how to change those.

Got it working!
Turns out that I needed to use the “experimental” check box of “Enable Gradle instead of Ant”, found under Platforms → Android:

I’ve read that in 4.18, the default for Android will be gradle instead of ant (so this means ant will no longer be supported?), so this might explain why this checkbox fixed my build/packaging errors.

Although, I ran this issue when my game loaded on device:

I had to turn off Multi-View & Multi-View Direct. All was fine then.
Things seem to be working now on Daydream at least. I’m nervous to switch back to my Oculus/GearVR version…

Hi Chris - does this work by default now in the newly released 4.18.0 binary?
