Upgrading old 5.5 project to 2017.4 LTS

An article by mgear

So had to upgrade one old Android+iOS cardboard app into newer unity version..
(Due to old unity doesn’t support latest apple os updates [link], missing new app store image sizes [link], some plugins are getting fixes/updates to newer versions, Android google play has new requirements coming up [link], and would be nice to use new unity videoplayer etc..)

Project has multiple external plugins from asset store (including EasyMovieTexture, YoutubePlayer/API, MoonSharp, ToonShaders, UberLogger, LeanTween, Old GVR 0.7 ..), and many custom shaders.

Surprisingly auto-upgrade went cleanly, and iOS build works fine.. BUT, android build crashes on start, with the error below:

	// caused by old GVR 0.7

	Error below, caused by either
	– androidmanifest.xml, too small min/target sdk, set both to 21 for 2017.4
	– or phone had denied installing (you pressed deny, instead of allow), go to Settings/DeveloperSettings/Permissions/Install via usb, should have blocked your app, disable and try again

For the script updates, only manual work was to rename these couple changed method/names:

Application.bundleIdentifier > Application.identifier
Caching.CleanCache() > Caching.ClearCache()
animator.Stop() > animator.enabled = false;

These things updated automagically:

mul(UNITY_MATRIX_MVP, pos) > UnityObjectToClipPos(pos)
packedNativeUnityEngineObject.classId > packedNativeUnityEngineObject.nativeTypeArrayIndex
packedNativeType.baseClassId > packedNativeType.nativeBaseTypeArrayIndex
EventType.mouseDown > EventType.MouseDown
EventType.mouseUp > EventType.MouseUp
EventType.mouseDrag > EventType.MouseDrag
EventType.scrollWheel > EventType.ScrollWheel
www.isError > www.isNetworkError
VRSettings.enabled > UnityEngine.XR.XRSettings.enabled
lineRenderer.numPositions > lineRenderer.positionCount
UnityWebRequest.GetTexture > UnityWebRequestTexture.GetTexture
VRNode m_VRNode = VRNode.Head > UnityEngine.XR.XRNode m_VRNode = UnityEngine.XR.XRNode.Head
InputTracking.GetLocalRotation > UnityEngine.XR.InputTracking.GetLocalRotation

One thing i noticed, the old undocumented findChild() seems to be removed.. which might be slower now(?) if it searches whole scene then:

go.FindChild("name") > go.Find("name")

Other notes:
– Main app icon in Player Settings seems to be empty, had to assign that back
– Api compatibility setting had changed from 2.0, back into 2.0 subset, which caused build errors with one plugin, had to assign it back to full 2.0:
“ArgumentException: The Assembly System.Web is referenced by YoutubeUnity (‘Assets/Youtube/YoutubePlayer/Plugins/YoutubeUnity.dll’). But the dll is not allowed to be included or could not be found.”
– APK Build size went up from 75mb > 89mb
– iOS build works fine, Android build crashes on start (see error log above) *currently not yet solved, probably will try updating GVR later.. [forum link]

Final Results:

– Reverted back and updated to 5.6.5p3 instead.. old gvr still works with that.
