Unity Engine

After upgrading an existing Android game to Unity 5.6.1p3 with Google VR SDK 1.60, I now get an immediate crash “Unfortunately, app has stopped” message. I opened Android Studio and looked in the logcat window:

I’ve got the Google Cardboard app installed and I can see the link to the game in there okay, so I wonder what is missing? My settings are as follows:

  • 32 bit display buffer is off
  • Colour space is Gamma
  • Auto Graphics API enabled
  • Multithreaded rendering off
  • Virtual reality SDKs are set to Cardboard (16-bit depth)
  • Stereo rendering method is multi-pass
  • Minimum API level set to 4.4 Kit-Kat (API level 19)
  • Scripting backend is Mono2x
  • Device filter is FAT (ARMv7 and x86)
  • Stripping level disabled

I’ve tried a variety of combinations of the settings above but nothing seems to make a difference.

I am using the GoogleVR audio spatializer too, and there is something in the log about an “unknown stream type” but I have been using that spatializer previously without a problem.

Does anyone have any suggestions for me? Thank you in advance!

Fixed it courtesy of this post: http://baba-s.hatenablog.com/entry/2017/02/13/100000

I had to edit the /plugins/android/AndroidManifest-Cardboard.xml to replace
com.google.unity.GoogleUnityActivity
with
com.unity3d.player.UnityPlayerActivity

I then copied saved a copy of that file as AndroidManifest.xml along side the other one as I needed to add the licence check permission.

The game runs successfully now!

How? How do you edit this? Did you edit it on your phone, or in Unity? i don’t understand how to edit this? please help explain it.

Whilst you’re in Unity, look in the /Plugins/Android folder and you’ll see the AndroidManifest-Cardboard.xml that I mentioned in my post.

Edit the line as I explained - but I don’t think you need to make a separate AndroidManifest.xml yourself unless you also need to add in further settings for both Cardboard and Daydream.

Rebuild your project - best of luck!
