Closing unity screen and relaunching it crashes the app

TarekMedhat commented 5 years ago

The unity app run the first time i launch the screen, if I navigate back and reopen the app crashes.

steps: 1- opening unity screen and unity project is running fine. 2- navigate back, this exception is shown: E/flutter ( 7701): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: MissingPluginException(No implementation found for method dispose on channel unity_view_0) E/flutter ( 7701): #0 MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:314:7) E/flutter ( 7701): <asynchronous suspension> E/flutter ( 7701): #1 UnityWidgetController._dispose (package:flutter_unity_widget/flutter_unity_widget.dart:55:19) E/flutter ( 7701): <asynchronous suspension> E/flutter ( 7701): #2 _UnityWidgetState.dispose (package:flutter_unity_widget/flutter_unity_widget.dart:103:19) E/flutter ( 7701): #3 StatefulElement.unmount (package:flutter/src/widgets/framework.dart:4107:12) E/flutter ( 7701): #4 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1737:13) E/flutter ( 7701): #5 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #6 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #7 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #8 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #9 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #10 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #11 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #12 MultiChildRenderObjectElement.visitChildren (package:flutter/src/widgets/framework.dart:5181:16) E/flutter ( 7701): #13 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #14 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #15 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #16 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #17 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #18 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #19 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #20 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #21 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #22 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #23 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #24 SingleChildRenderObjectElement.visitChildren (package:flutter/src/widgets/framework.dart:5080:14) E/flutter ( 7701): #25 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #26 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #27 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #28 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #29 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #30 SingleChildRenderObjectElement.visitChildren (package:flutter/src/widgets/framework.dart:5080:14) E/flutter ( 7701): #31 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #32 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #33 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #34 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #35 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #36 ComponentElement.visitChildren (package:flutter/src/widgets/framework.dart:3955:14) E/flutter ( 7701): #37 _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1733:13) E/flutter ( 7701): #38 _InactiveElements._unmount.<anonymous closure> (package:flutter/src/widgets/framework.dart:1735:7) E/flutter ( 7701): #39 ComponentElement.visitChildren

how can successfully handle disposing and launching unity?

TarekMedhat commented 5 years ago

All I could do for now is to prevent the unity player from quitting on disposing by removing UnityUtils.getPlayer().quit(); from the library dispose method in android. So that the game will keep running on background even if the screen is disposed, relaunching the screen will resume the game on the last state. flutter-unity-view-widget/android/src/FlutterUnityView @Override public void dispose() { if (UnityUtils.isUnityReady()) { // UnityUtils.getPlayer().quit(); } }

thomas-stockx commented 5 years ago

I think your logs are a red herring, as it points towards this: https://stackoverflow.com/questions/51959096/no-implementation-found-for-void-com-unity3d-player-unityplayer-nativerestartact

Are you sure you're using the unity-classes.jar that is exported by your Unity version?

thomas-stockx commented 5 years ago

Seems like UnityPlayer.quit() also kills the app it's running in.

We might need to take a look at the newest version of Unity as a Library (https://forum.unity.com/threads/integration-unity-as-a-library-in-native-android-app-version-2.751712/) which added a UnityPlayer.unload() method to address this exact issue.

PiotrxKolasinski commented 5 years ago

I reviewed this error and the problem is the onDestroy() method of the UnityPlayer class. And exactly this piece of code:

  if (this.mProcessKillRequested) {
            if (this.m_UnityPlayerLifecycleEvents != null) {
                this.m_UnityPlayerLifecycleEvents.onUnityPlayerQuitted();
            } else {
                this.onUnityPlayerQuitted();
            }

            Process.killProcess(Process.myPid());
        }

To solve this problem, you need to create MainUnityActivity in a separate process :) Then the .quit() method will only kill this process.

How can you try to fix it: First way: In your example (https://forum.unity.com/threads/integration-unity-as-a-library-in-native-android-app-version-2.751712/) In AndroidManifest.xml file They add, for MainUnityActivity class, attribute android:process=":Unity" . https://stackoverflow.com/questions/7142921/usage-of-androidprocess Second way: https://medium.com/flutter/executing-dart-in-the-background-with-flutter-plugins-and-geofencing-2b3e40a1a124 Third way: https://developer.squareup.com/blog/flutter-android-and-process-death/

Maybe something of this will be helpful :)

RomanTechnologies commented 4 years ago

Hi, Just wondering if you will be merging a solution for this into the plugin in the near future?

RomanTechnologies commented 4 years ago

I have tried changing UnityUtils.getPlayer().quit to unload() instead and it stops the the activity from being disposed, however I get a black screen when launching the widget again, so I assume more needs to be handled as what I did only handles one part.

Would you know what else I would need to do to clear up the widget to be able to use it again in a clean fashion?

Thanks

assemmarwan commented 4 years ago

@RomanTechnologies Yeah, same here. Right now I have forked the project and commented out UnityUtils.getPlayer().quit() to stop the crashing. But this has the side-effect of leaving all the objects still active in the scene (which can be handled manually through messages)

After reading about it, I have also attempted to add the below in the manifest, but no luck :(

        <activity
            android:name=".UnityPlayerActivity"
            android:launchMode="singleTask"
            android:process=":unityplayer123" />

I can't tell if this is an issue with the Unity's android library or the plugin's? Or both 🙃

RomanTechnologies commented 4 years ago

@assemmarwan Yeah I have done the same, so when disposing of the widget it doesnt close the activity. This is all due to the library needing to update the .quit() method to unload() as unity added this specifically due to the issues on android. I have done that but it needs more work so I will wait until the authors have a clean solution merged in.

I've tried switching to .unload() instead of .quit(), but saw similar issues (black screen, seemingly not properly re-instantiating the Unity app).

Hi, is there a solution yet? I actually never encountered this issue, till I needed to reinstall windows, and suddenly, it would crash after changing screens through a BottomNavBar... I tried to recreate the old state (manually redownloading old versions, ...), but can't get it to work anymore.

EDIT :

Ok I resolve my own issue, I just have to modified the yaml to point to the modified plugin that I download from @assemmarwan , I hope soon someone fix this problem. but for now this resolve the issue like @assemmarwan said, one can handle this kind of things via messages.

What I'm doing is the first thing, keep running the unity app on the background. How I achieve it on Android is downloading the repository, locally on my computer. Then modified the file

flutter-unity-view-widget\android\src\main\java\com\rexraphael\flutterunitywidget\FlutterUnityView.java

and comment the line UnityUtils.getPlayer().quit() and save it.

Then on pubspec.yaml I comment the one that is referencing to the online and use the one that is locally on my computer, like this: #flutter_unity_widget: ^0.1.6+8 flutter_unity_widget: path: ./plugin_flutter_unity/flutter-unity-view-widget/

I hope this guide you on how to solve this issue for android.

But does your scene unload, or does it stay open and maintain state?

Darkmax commented 4 years ago

I pause it inside unity, and when I open again the screen and resume or load again the scene depending of what I want.

Jairolaya12x commented 4 years ago

Hi, I remember that use the same solution: [Remove the Quit(), and call the scene with new data o change the data with some function from flutter] I don't shared the experience because later I had a error with the AR flag in the widget, (Sorry for this 😥 , this may have been useful for your projects)

In my app the user should be can change between 3D and AR view.

Problem 1: If change the data of the widget isARScene: {value}, to other value the app close, maybe for the same problem with the quit, but thinking again, a possible solution is only send the data to unity and disable or enable the AR camera with the 3D camera and don't change the isARScene: {value} [always set to true, because if the isARScene is false the camera don't start, ]

Problem 2: In some cases with change to other app and re open the app from the background with application manager the app, closes [Only in android, in iOS i don't remember if works perfect]

I'll retake the project with the possible solution for problem 1 and share the result of the test.

Regards! 🤘🏻

@RomanTechnologies Yeah, same here. Right now I have forked the project and commented out UnityUtils.getPlayer().quit() to stop the crashing. But this has the side-effect of leaving all the objects still active in the scene (which can be handled manually through messages) After reading about it, I have also attempted to add the below in the manifest, but no luck :(
        <activity
            android:name=".UnityPlayerActivity"
            android:launchMode="singleTask"
            android:process=":unityplayer123" />
I can't tell if this is an issue with the Unity's android library or the plugin's? Or both 🙃
@assemmarwan I tried to implement your fix and comment out the UnityUtils.getPlayer.quit() but on my own project I don't have that file where on the main is (FlutterUnityView.java), how can I modified that on my own project?, do I need to download something and recompile the plugin?, if yes would you be kindly to guide me on this? Sorry for this, but I tried already wihout succes several times and still don't know how to solve it
Ok I resolve my own issue, I just have to modified the yaml to point to the modified plugin that I download from @assemmarwan , I hope soon someone fix this problem. but for now this resolve the issue like @assemmarwan said, one can handle this kind of things via messages.

thanks

I tried your way but it did not worked. can you share me you code base?

From Android studio navigate to -> External Libraries -> Flutter Plugins -> flutter_unity_widget plugin -> android/src/main/java/com/rexraphael/flutterunitywidget/FlutterUnityView comment UnityUtils.getPlayer().quit();in the dispose method
```
@Override
public void dispose() {
    if (UnityUtils.isUnityReady()) {
        // UnityUtils.getPlayer().quit();
    }
}
```
but as mentioned doing that keeps all the objects active in the scene (which can be handled manually through messages)

Thanks for the solution app stop quitting but i am getting some null method exception how to handle that can you explain that

if you are talking about [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: MissingPluginException(No implementation found for method dispose on channel unity_view_0) Don't worry it's not an issue, there is no implementation for this method in the plugin but it's sent through the method channel, so just basically ignore it

Hi, feel free to experiment or create a pull request. I've tried switching to .unload() instead of .quit(), but saw similar issues (black screen, seemingly not properly re-instantiating the Unity app). Please do keep in mind that Unity as a Library is still in beta and not properly supported by Unity, so there might not even be a solution for it just yet. Even so, your solution might be more clean than mine (if I ever come up with one), so we're always open for pull requests!

It seems we have two options for navigating off and back onto a widget with Unity view.

Unity never quits running in the background and maintains state or crashes on re-entry

Black screen on re-entry (I'm actually achieving this scenario by running Application.Quit(); from Unity prior to popping out of the widget.

Anybody find a way to fix this yet? @assemmarwan @Darkmax @RomanTechnologies @Jairolaya12x

What I'm doing is the first thing, keep running the unity app on the background. How I achieve it on Android is downloading the repository, locally on my computer. Then modified the file

flutter-unity-view-widget\android\src\main\java\com\rexraphael\flutterunitywidget\FlutterUnityView.java

and comment the line UnityUtils.getPlayer().quit() and save it. Then on pubspec.yaml I comment the one that is referencing to the online and use the one that is locally on my computer, like this: #flutter_unity_widget: ^0.1.6+8 flutter_unity_widget: path: ./plugin_flutter_unity/flutter-unity-view-widget/ I hope this guide you on how to solve this issue for android.

But does your scene unload, or does it stay open and maintain state?

This one fix the problem for me, just to mention :),

thanks Mate SLim

I would love to see this fix merged in... along with many others. I'm drowning in monkey patches over here. 🙈

sinano1107 commented 4 years ago

On iOS. ・controller.resume() in onUnityCreated(). Do not execute. ・Execute controller.resume() in dispose(). Doing these things will solve the problem.

I don't know the inner workings of it, so this seems very strange to me.

chatorn-ketsom commented 4 years ago

My workaround was similar to that of you guys.

Mine(in my forked version of this repo) is as follows:

In android/src/main/java/com/rexraphael/flutterunitywidget/FlutterUnityView.java 1.1 In dispose method, I commented out UnityUtils.getPlayer().quit() and added UnityUtils.pause() instead:
```
@Override
public void dispose() {
    if (UnityUtils.isUnityReady()) {
        // UnityUtils.getPlayer().quit();
        UnityUtils.pause();
    }
}
```

1.2 In onMethodCall method for case "createUnity", I added the following statement in onReady callback :

      if(UnityUtils.isUnityPaused()){
          UnityUtils.resume();
      }

as shown below:

        ...
        case "createUnity":
                String isAR;
                isAR = methodCall.argument("isAR");

                if (isAR != null) {
                    UnityUtils.isAR = true;
                }

                UnityUtils.createPlayer(registrar.activity(), new UnityUtils.CreateCallback() {
                    @Override
                    public void onReady() {
                        result.success(true);

                        if(UnityUtils.isUnityPaused()){
                            UnityUtils.resume();
                        }
                    }
                });

                break;
           ...

In my own flutter project using UnityWidget, I posted a message to call my implemented Restart method in Unity so that all the already tracked images (AR!) will be cleared:

  ...
  SomeWidget(
        child: UnityWidget(
           isARScene: true,
           onUnityViewCreated: _onUnityCreated,
         ),
  )
  ...

  void _onUnityCreated(controller) async {
      this._unityWidgetController = controller;

      // Here
      final bool isReady = await this._unityWidgetController.isReady();
      if (isReady) {
        this
            ._unityWidgetController
            .postMessage("myObject", "Restart", "");
      }
   }

It seemed working fine. I was able to exit Unity player by pressing back button and load it back again without my flutter app being crashed or terminated after exiting Unity. However, I'm still facing an AR related problem showing black screen which, I know, is not related to this issue. :smile: Cheers!

New 2.0.0 release fixes this issue :)

heshamerfan97 commented 3 years ago

The above issue is still shown in the new flutter_unity_widget: ^3.0.3 And the above workaround of commenting UnityUtils.getPlayer().quit(); is not available anymore because the file "FlutterUnityView.java" is not there anymore and replaced by a lot of other java files I also tried commenting the lines in the new quitPlayer method in android/src/main/java/com/xraph/plugins/flutterunitywidget/UnityUtils.java to be as following

public static void quitPlayer() {
        try {
            if (unityPlayer != null) {
                //unityPlayer.quit();
                //_isUnityLoaded = false;
                //_isUnityReady = false;
                //unityPlayer = null;
            }
        } catch (Error e) {
            Log.e(LOG_TAG, e.getMessage());
        }
    }

and in android/src/main/java/com/xraph/plugins/flutterunitywidget/UnityView.java to be as following

public void quitPlayer() {
    try {
      if (unityPlayer != null) {
        //unityPlayer.quit();
        //setUnityLoaded(false);
        //setUnityReady(false);
        //unityPlayer = null;
      }
    } catch (Error e) {
      Log.e(LOG_TAG, e.getMessage());
    }
  }

But this also didn't work and the app still crashes at reopening the screen with UnityWidget in it.

still not fixed

muck27 commented 2 years ago

My game scene does not render the second time I try to play it. I tried adding a WillPopScope as mentioned in the comment of #400. The scene renders successfully the second time sometimes but most of the times it doesnt. Is there a fix for this issue yet? @thomas-stockx

mahinikaras commented 2 years ago

Still freezes app if I open unity second time. Even with the provided example. Is there any solution ?

juicycleff commented 2 years ago

I believe this issue has been solved

ext-danny commented 1 year ago

The unity app still crashes when clicked on back button and try to reopen it.

qiaodongliang commented 1 year ago

still not fixed

timbotimbo commented 1 year ago

@qiaodongliang If you have a crash or bug with the current plugin, please make a new issue with reproduction steps and error messages.

Responding to a 3 year old issue that mentions code that probably doesn't even exist anymore won't help anyone solve your issue.

Closing unity screen and relaunching it crashes the app #46
