Examples crashing when built with Unity 2017.1 about tango-examples-unity

[ultra-sonic]

same here...compiles fine but crashes instantly on device (Zenfone AR)

[chaosemer]

Don't worry, Tango isn't getting dropped. 2017.2 brings native Tango support and we're focused on making that awesome.

Just tried with 2017.2 beta and the crash still exists. Will this be expected to be fixed when 2017.2 is released? This seems to suggest not unless it wont be fixed for the beta but will be for the release? Thanks for any insight

Thanks for the bug report. We will look into the issue.

here compiles fine but crashes on runtime instantly

I'm getting the same on a Tango Example

[ObjSal]

I still don't know why, but recompiling google_unity_wrapper.aar fixed the java.lang.NoSuchMethodError runtime crash for me.

[danzeeeman]

I down graded to Unity 5.6.2p4 and everything works fine

[salgue]

@danzeeeman even though what you say might work, I don't think is a solution for the long run.

@chaosemer also claims that for a stable Tango development we use Unity versions 5.2 - 5.6 in issue #103

My question is, when is Tango going to be supported in Unity 2017 for stable development?

Should we even be worried that the support for the tango plugin might get dropped?

[aresares]

@ObjSal sorry how did you recompilet google_unity_wrapper.aar

[ObjSal]

Sorry if I get something wrong, I paused my Tango development till Unity fixes the Tango support in Unity 2017+.

The below steps only fixed the issue where the app crashes with No direct method <init>(Landroid/content/ContextWrapper;)V in class Lcom/unity3d/player/UnityPlayer when running from the device; debugging/running directly from Unity won't work.

Note that my case is not a usual scenario for Unity developers, because when I export the android project I include it as a library in another android project; here are the steps just in case it helps:

I downloaded the Tango libraries and copy them to the below locations:
AndroidIntegration/GoogleUnityWrapper/aar/tango-cloud-lib.aar AndroidIntegration/GoogleUnityWrapper/aar/tango-ux-support-library.aar AndroidIntegration/GoogleUnityWrapper/aar/tango_java_lib.aar AndroidIntegration/GoogleUnityWrapper/aar/tango_unity_helper.aar AndroidIntegration/GoogleUnityWrapper/aar/unity_ux_helper.aar

I then copy the unity-classes.jar from Unity 2017 and place it in:
AndroidIntegration/GoogleUnityWrapper/unity-classes.jar

Then I created a build.gradle within AndroidIntegration/GoogleUnityWrapper/, you may see the script within this gist as the formatting didn't work well here.

Then build using Android Studio:

The AAR file should be generated in the build output directory.

I hope Unity fixes their (or this plugin) implementation.

[YohanBaillot]

Thanks Salavador. Anyway you could share the AAR file?

Why not just use the aar I shared. And modify the DynamicMesh.cs yourself.
I just modify the byte code directly in the class. And it's working.

But I'm just curious whether anyone makes the 2017.2 built-in integration work. Mine reports failed to connect to Tango.

How to solve this?

Read the google plus post above. @neelkadia

Thank you @SetoKaiba.
Life savior.
Same scenario: 2017.1f1 version and Asus AR.
Guys, don't forget to add || UNITY_2017 at line 628 in TangoDynamicMesh.cs
