[CRASH]es when Quitting the app (Application.Quit()) since 2018.4.20f1

In our latest build of our app we have started to see this too.

• Built using Unity 2018.4.20f1
• Happens when the user quits the app (Application.Quit)
• Several crashes reported:
  

  • No implementation found for boolean com.unity3d.player.UnityPlayer.nativeInjectEvent(android.view.InputEvent) (tried Java_com_unity3d_player_UnityPlayer_nativeInjectEvent and Java_com_unity3d_player_UnityPlayer_nativeInjectEvent__Landroid_view_InputEvent_2)

    • is what is being reported most often as well / affecting most users

• We don't use Google Play Games, as was reported to be a likely cause for the above crash here.
• We have several other similar issues also happening when quitting. All new issues since the latest build (using the mentioned Unity version)

  • Native method not found: com.unity3d.player.UnityPlayer.nativeRecreateGfxState:(ILandroid/view/Surface;)V

  • No implementation found for void com.unity3d.player.UnityPlayer.nativeFocusChanged(boolean) (tried Java_com_unity3d_player_UnityPlayer_nativeFocusChanged and Java_com_unity3d_player_UnityPlayer_nativeFocusChanged__Z)

  • No implementation found for void com.unity3d.player.UnityPlayer.initJni(android.content.Context) (tried Java_com_unity3d_player_UnityPlayer_initJni and Java_com_unity3d_player_UnityPlayer_initJni__Landroid_content_Context_2)

    
    
  • These logs are from Firebase. More complete logs below.
• Although all the crashes happen when quitting. We are unable to reproduce the issue on our own devices.

I recently created an bug report with repro for this problem. The issue is If any touch input is received after triggering Application.Quit() (just spam quit button), the app throws this and several similar UnsatisfiedLinkError.

Case Id: 1238096

 

Would you let me/us know when your submitted issue gets verified / posted on the issue tracker?
So I can vote on it.
In the meantime the issue may be related to this one: https://issuetracker.unity3d.com/issues/android-app-crashes-after-executing-application-dot-quit

Although even with your clear steps to reproduce the issue. Doing this on my own devices, doesn't seem to make our app crash.

 

This morning woke up to another report about a crash happening on application quit:

java.lang.UnsatisfiedLinkError: No implementation found for void com.unity3d.player.UnityPlayer.nativeDone()

Just wondering.
Did you remove all options to quit from your app or used a different way to close it?

Spoiler: Using something like this

Code (CSharp):

1. System.Diagnostics.Process.GetCurrentProcess().Kill();

or Backgrounding instead of quitting

Code (CSharp):

1.  
2. AndroidJavaObject __activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
3.             __activity.Call<bool>("moveTaskToBack", true);

 

We change with backgrounding on Android

 

Cool. Thanks for sharing this information.
It will save us some time.

 

We experience the same issue.

 

Just now did a test.
Built with 2018.4.21f1, and after backgrounding, tried to do an Application.Unload() which resulted in another crash.

Hopefully this will assist Unity in discovering the cause of the issue.
Here's also hoping we may get an official response from someone soon.

In the meantime, simply backgrounding solves our (immediate) issue.

 

In a new production build. Built with 2018.4.21f1 at a point where we don't call Application.Quit (since we only do the backgrounding now; see above), but OnApplicationQuit() is being called anyway, we still receive the following crash.

Would be great to have someone from Unity chime in on this soon!
Maybe @Tomas1856 could take a look?
I mean it clearly started since 2018.4.20 and we can try to make workaround solutions, but it's an Unity issue.
Would be good to know that Unity is at least aware of this problem (has seen this thread).

 

Great to hear!
Thanks for letting us know.

 

In which release will fix be out. We are also facing the same issue.

 

Hi, I have the same issue in production. I hope it will be fixed very soon!
Is there an release date for 2018.4.23?

 

Hi, ok thanks for that info. I'm going to test 2018.4.22f1 and let you know if the fix is working.

 

Is this really fixed in 2018.4.22f1? I was wondering if it was confirmed.

 

Yeah I'd be interested as well in knowing if it was fixed.

 

@jwtan_unity @JuliusM

Has this definitely been fixed in 2018.4.22? We are experiencing a lot of quit crashes that are severely impacting our android app health and consequently our install numbers.

 

It may be too soon to tell (still slowly rolling out our new release), but seems to no longer appear in our crash logs. Build using 2018.4.23f1

 

We can confirm this has been fixed now in 2018.4.23. Thanks!

 

I can see such errors after Application.Quit in unity 2020.3.34, 2020.3.35, 2020.3.36.
libunity.so nativeDone(_JNIEnv*, _jobject*)

 

Tested on 2020.3.37 and on 2020.3.38 and I can still see the issue.
