Unity 2017.2 and 5.6.4 not working with GVR 1.110 manifest merging error

[sean369see]

I only want to build the example scene for cardboard but I am seeing the now well-known manifest merge problem. I even tried testing the custom unity package from the link below but that still didn't build as well.

The previous thread on this topic:

Anyone encounter this old issue again with the latest versions of unity and gvr?
Please download the example project showing this error here:
https://www.dropbox.com/s/e0cerk9r0rwtwsr/TestGVR.zip?dl=0

Found using:

• Google VR SDK version: 1.110
• Tested using both Unity version: 5.6.4 and 2017.2

Steps to reproduce the issue:

1. Create new empty unity 3d project.
2. Import gvr 1.110
3. Set scene to GVR demo
4. Switch to android (make sure the scene runs in editor) and build according to official instructions (min android sdk is 19, target at 24 or highest, adding cardboard after checking virtual reality supported in unity, etc.)
5. Android manifest merge error is produced.

Best,
Sean

Thanks for providing the repro project. I was able to build an Android APK using your project using Unity 2017.2.0p1. I didn't chance any of the settings after opening the TestGVR.zip project you provided.

Can you include the full console error messages text you see when you try to build?

Also, please check that the correct value is set for the Android SDK under "External Tools" section of the Unity preferences.

Thanks for your quick reply. I have the android SDK set to the root folder with path C:\AndroidStudioSDK. I can build the unity sample program particles demo as an android apk with no problems.

It sounds like you might be running into Unity case 888859.

If so, you can either:

1. Upgrade to a version of Unity that fixes this issue
2. Downgrade the Android SDK 'tools' folder to a version compatible with your version of Unity

To try the tools downgrade option:

1. Rename C:\AndroidStudioSDK\tools to C:\AndroidStudioSDK\tools-backup-for-issue789
2. Download https://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip
3. Extract the zip file into C:\AndroidStudioSDK\, which will create a new, downgraded C:\AndroidStudioSDK\tools
4. Try building your APK from Unity again.

Thanks! This worked for Unity 2017.2.0f3 after applying the tools downgrade.

If you're doing Daydream development, we recommend you update to the latest 2017.2.0 patch release as 2017.2.0f3 has an issue where the Daydream controller will stop working after background > foreground.
