I have followed the getting started steps here: https://developers.google.com/cardboard/unity/get-started
But when I load the .apk file to my phone, I get a "There was a problem parsing the package" error.
I tried searching online and I assume it means I have an issue somewhere in my AndroidManifest.xml file?
Is there anything else I need to be aware of that the get-started guide didn't mention?
Found the solution!
Open the Android manifest file inside YourProject/Assets/Plugins/Android/AndroidManifest.xml and change the value of android:minSdkVersion to 16. It was 19 by default.
If it helps I'm doing this on a Samsung Galaxy S2 with Android version 4.1.2
