Integration Unity as a library in native Android app Version 2

Looks like the way the unloading/quitting issues were addressed is by having Unity run in a separate process and explicitly killing it.

This was the workaround that my team had investigated but ultimately our client is unwilling to operate with the JVM split into multiple processes. This is because they use Android UI elements over the Unity view that need to access the objects from the app's memory. To continue doing this, they would need to replicate their main process memory in the Unity process.

Ultimately we found other workarounds to use Unity in the same process but workarounds are not what we like to ship in production code. Will there be any solution (like tightening up Unity's shut-down sequence) for apps that cannot be split?

 

@PavelLU Would you be able to provide the steps required to make a 2019.3.b1-3 project compliant with b4+ build?

 

This all is exactly what I was looking for! I'm working on making an Android AR function into my native android app using Unity as a Library. However, when I import the ARCore package in the example app it immediately crashes. Do I need to enable anything in the standard Android app provided to get AR working?

I tried with both AR Foundation + ARCore through package manager and the ARCore provided as a .unitypackage. Both make the unity part of the app crash instantly, even when I'm not using anything of it yet. Just having it in htere makes it crash.

 

I'm getting the same error ...

 

I got it working! I had to enable Player > Configuration > Scripting Backend to IL2CPP and Player > Configuration > Target Architectures > ARM64.

 

Using Unity project in this thread with Unity2019.3.0b5, I could compile it to Android, IL2CPP, ARM64.

But when I include Vuforia to the project I get compilation errors:

Hi, I have issues trying to build a Android build, tried it on emulator and on phone. But it always crashes when I clicked Open in Unity. The thing is there is no error at all in the Android Studio's logcat and build logs.

Anyone knows what's happening? It even happens with the full build that is "completed"

 

Can someone check if unity default videoplayer component plays when added to ar when unity is built as a library? Ive just ported my unity app as a library( my app uses a plane to play a video when a marker is detected). If i build it as a unity app and install it works ok. But if i include as library the plane shows but not video or audio is played...

 

Same error when building an apk ( IL2CPP, .net 4 or 2, ARM64):

Is there any settings that the guide above is missing? I've followed the guide step by step and I've checked it multiple times and still it crashes on clicking the Open Unity within the app.

 

Seems like there may be a step missing around how you incorporate the OverrideUnityActivity into the native app. The example implementation works but I can't discern a difference between that and my custom attempt.

 

The example project extends OverrideUnityActivity with MainUnityActivity but MainUnityActivity isn't mentioned in the walkthrough. Some sort of linking/namespacing issue? Hope this helps.

 

I

I applied AR Foundation. My app crushes when I open the Unity window in native android app. Does anyone know the reason why?

 

same issue. I just applied AR foundation to the example project they have and build it again. The unity window crashes in native app.

 

Did you enable Player > Configuration > Scripting Backend to IL2CPP and Player > Configuration > Target Architectures > ARM64 ?

 

@HedwigMendix I tried to apply the settings and built it again. But it doesn't work still. Still crashes without any errors.

 

I'm also on the b5 version, that could be it?

 

I managed to get it to work by turning off Engine Stripping in the configurations. This step is not stated in the tutorial above.

 

@charmcrescini how did you manage to get ARFoundation to run? I tried to export the ARFoundation project as a test to Android Studio and followed the above flow. But these few lines that presumably is added by Unity to handle AR functionality is giving Unresolved depencies errors in Android Studio:

implementation(name: 'arcore_client', ext:'aar')
implementation(name: 'ARPresto', ext:'aar')
implementation(name: 'unityandroidpermissions', ext:'aar')
implementation(name: 'UnityARCore', ext:'aar')

 

Tried here with two different versions: 2019.3.0b5 and 2019.3.07. Same error under same conditions, even with a blank project just with Vuforia...

 

This work with Flutter???
There is a way to trade data between the "parent native app" and the unity process?

 

You can use JNI but my team has found that socket-based messaging is much faster.

 

Anyone managed to make ARFoundation or Vuforia work with Android Studio with Unity as a Library?

Thanks in advanced for the help.

 

Hello Everyone, I am new to native android programming. I have been able to achieve a similar feature where we make AAR file from the Unity Exported project and the native android app can launch it with a button press. I have been trying this new library method but getting an error on
MainUnityActivity.class (Unresolved symbol). I have attached the screenshots of the code that I have modified. Not sure what I am doing wrong here.

 

Hi all, I have a fundamental question. So far this Unity as a Library function allows Android Studio to run Unity based programs as a sort of a extension. But essentially this means it's running 2 different apps - 1 Android Studio and the other Unity.
Is there a way to access Unity's ARFoundation functions in Android Studio to implement AR functionality using Android Studio completely and using Unity's library just to access the apis.

Would appreciate if there is a answer for it.

 

AFAIK the unity APIs are not exposed to Java.

However, you can write your own Java layer which sends messages to a .Net receiver (that you also need to write) which then calls the Unity functions you desire.

 

Has anyone experience any performance issues with the beta and second version of these instructions? In our project loading a scene can sometimes take 5-10 seconds which didn't happen before with the alpha.

Profiling the app it seems like Unity is stuck on a method called "UpdatePreloading"

I found by removing the majority of scenes in our project, the problem went away - it seems to be that the load time becomes worse with an increase in the number of scenes in our project. This isn't the case when I added a lot of empty scenes, so it seems to be something about the other scenes referencing assets, which I don't understand.

 

Socket-base = a kind of internal network?

 

Yes. We have a server on one end and a client on the other, both using a specific port on localhost.

 

@btristan Do you have any examples regarding the .NET layer? I'm relatively new to .NET

 

It depends on where you want your server to be. (you could also write your system to have the ability to start a server on either side, for more flexibility - which is what my team did)

If you want to have your server be on the .NET side: https://docs.microsoft.com/en-us/dotnet/api/system.net.sockets.tcplistener?view=netframework-4.7.1

Here is the .NET client: https://docs.microsoft.com/en-us/dotnet/api/system.net.sockets.tcpclient?view=netframework-4.7.1

Java has similar systems. Here is the server: https://docs.oracle.com/javase/8/docs/api/java/net/ServerSocket.html

And here is the Java client: https://docs.oracle.com/javase/8/docs/api/java/net/Socket.html

The servers both operate the same way in that any new connection will spin off a client to talk to the remote. This is nice because then the code to talk to each side is essentially the same. (just in different languages)

I do all this off the main thread. (I don't want to impact the frame rate) I have wrapped each client in a class that can accept messages and puts them into a blocking queue. When the message is in the queue a thread takes the message, serializes it, and writes the bytes into the client which will send it to the remote. When a message is received by a client, I have it put into another blocking queue which is processed on yet another thread. After the message is deserialized it is sent to a message dispatcher which decides where the message should go.

 

@btristan Wow, thank you so much for the super comprehensive answer. Will try to implement on my end; fingers crossed! Once again, thank you!

 

Solved!

Using Unity 2019.3.0b8 (maybe it works with previous versions). I updated Vuforia to 8.5.8.

Exported gladle project, integrated to native app, and debugged on Samsung S8.


Using Unity project in this thread with Unity2019.3.0b8, I could compile it to Android, IL2CPP, ARM64.

But when I include Vuforia 8.3.8 to the project I get compilation errors for exporting project and compiling APK:

IL2CPP error for type 'UnityEngine.Experimental.Rendering.RenderPipeline' in assembly 'D:\Public\AndroidStudio\HoodooSDKtest\UnityProject\Temp\StagingArea\assets\bin\Data\Managed\UnityEngine.dll'

Hi,
With this example I understand that you can get unity values to the native app (box color in this example) but is the opposite possible? is it possible to get values from the native application in the unity app ?

 

Does anyone have same issue as below?
* unity 2019.3.0b8
* android studio
* IL2CPP, arm64

* in android studio, I run the app, that makes same icon twice as i attached.
left icon works fine, right icon shows error msg, just quit itself.

I would like to have a solution or tips even small one

Thanks

 

@Redbeanmouse maybe you missed out this line in the tutorial:

After installation there will be two icons added on the device. To leave only the icon of the main activity, remove <intent-filter>...</intent-filter> from the AndroidManifest.xml in unityLibrary

 

oops I did not pay attention to the important message...

• To leave only the icon of the main activity, remove <intent-filter>...</intent-filter> from the AndroidManifest.xml in unityLibrary

 

Thx... I found my mistake!!

 

Hey,


I'm experiencing an issue where the library works and behaves as it should on the PC where the library was first implemented but does not work when built from a version of the project pulled from Git on another PC. When the project is transferred from one PC to the other by USB the library works as it should. Any idea why this is happening? I am using an unaltered version of the .gitignore provided by Android Studio (posted below).

Hello, I have an issue - when I try to launch Unity Intent, immediately after I press "show unity" button, whole app crashes. Any tips for this? I'm simply building new example app
I'm using Unity 2019.3.0b10

EDIT: If anyone has this issue roll back to Android Studio 3.4.2, as Android Studio 3.5 won't work

 

Hi,

Is there any way to send a message from Unity as a library to Android ? The same way that we can send message from Android to Unity.

Thanks.

 

Is rendering to only part of the screen implemented? I mean, one could probably use a render texture, then bank on GLES2/3 (and not use Vulkan) and manually take the texture and use it in a native Android App.. Setting a 'device viewport' somewhere in .NET code would be really handy.

An even better way would be to manually render to a bounds / region.

 

There is a way!

Example:

Code (CSharp):

1. // Unity player (C#):
2. AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
3.  
4. AndroidJavaObject activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
5.  
6. activity.Call("gameFinished", gameIsFinished);

Here I'm calling the method gameFinished() which I defined in my MainUnityPlayer activity on the Android side and passing the gameIsFinished string as its parameter. I'm sure there's some documentation about it if you look for it.

 

I've finally managed to run ARFoundation in UaaL Below something which can help you on the way after buiding with IL2CPP option.

Info from thread of version 1 of this tutorial of how to overcome libmain.so error by @DylanFord

 

Hello Everyone,
We are trying to have a base native android application install multiple unity based games into the base application. The Android Dev team gets conflicts when they add multiple unity Gradle projects to their base projects.

unityLibrary\src\main\assets\bin\Data\Managed\Metadata\global-metadata.dat
They get a conflict here while making a build saying both modules have the same path.

I exported an IL2CPP Arm64 Gradle project and handed it over to them. I exported using 2019.3.11b as the new structure of exporting Gradle projects is better/ closer to the android project structure which made it easier for them to implement.

Any solution or suggestion would help. If more information is required please do let me know. I will speak to the team and update it here. Any help will be appreciated thank you.
