I'm curious if you have you been able to resolve this issue? I'm having the same behavior when ending the activity on Android = application exits. I need to be able to run Unity multiple times within the same app session - so attempting to close and reopen (or hide/pause and unhide/unpause).

 

Hi, I followed the steps and the unityLibrary is added. But when I build the project
I got an error : Dependent features configured but no package ID was set.
Please help.

 

Hi, I have the same problem, how did you resolve it?

 

hello,
is it possible to load the unity to a small fragment/frame inside the native android app instead of the current full screen activity ?

 

Yes, it is possible to load inside a fragment and we can define the size of the fragment as well.
You check out my tutorial as here I've used the fragment to insert the unity view. Currently in the sample it is a full screen fragment, however I'm sure you can easily modify the size of the fragment in the UnityFragment.kt

 

Hello Everyone,

I've created a tutorial which might help anyone how is looking to integrate unity into android. I'm embedding the unity view in a fragment so that the fragment can be used anywhere in Android. Another advantage I found of using the fragment is that native android controls can also be easily placed on top of the unity view, so that we can properly mix both of them together. Also on the Android side I've used Kotlin.
This tutorial is also having the two way communication between the Android and Unity.
The tutorial is following a step by step procedure based on Unity's on own post of using Unity as a library in Android.
If you've any concerns or comments, please do let me know about it.

 

Hi,

Project has a requirement of having Unity3D Library to be exported and used inside Android Native. All working fine now until I tried to have Agora Plugin to be integrated inside Unity3D and exported the project as Library. I am seeing

settings.gradle is having : implementation project('AgoraRtcEngineKit.plugin') in it.

I can also see a Folder of androidBuild/unityLibrary/AgoraRtcEngineKit.plugin

But I get the Compiler error on Gradle sync : Project with path ':unityLibrary\AgoraRtcEngineKit.plugin' could not be found in project ':app'.

I moved the Plugins folder to the Assets Root folder, even then same issue( to have it like Assets/Plugins/Android/AgoraRtcEngineKit.plugin )

note : I am using Unity3d.2019.4.7 LTS and Android Studio 4.0.1

Please help me out, tried a lot on this

 

I currently have issues with this, while trying to implement it together with Xamarin.

It seems Unity is closing the whole activity at almost random times. The app works fine, until I open a UnityPlayer and render it. If I navigate away from the UnityPlayer view, it seems Unity 'finishes' the app completely, which it really shouldn't be doing when it's being used as a library. Anyone else seen this before, and know how to tell Unity to stop doing that?

 

I am still getting error while using AR Foundation Plane tracking project export in Android native

Error: Your project contains C++ files but it is not using a supported native build system.
Consider using CMake or ndk-build integration. For more information, go to:
https://d.android.com/r/studio-ui/add-native-code.html
Alternatively, you can use the experimental plugin:
https://developer.android.com/r/tools/experimental-plugin.html

 

How we resolve 150mb aab file limitation? Can we use dynamic feature module for unityLibrary and launcher modules?

 

Could not find :arcore_client:. Required by: project :app > project :unityLibrary any solution on this error..
