Question Android crashes after update project to Unity 2020.3.9f

Hello. I've got many crash reports after update projects to Unity 2020.3.9f1 on android! Same situation with 2021.1.7f1.
I can't reproduce this on my devices.

this is report from firebase crashlytics:

Code (CSharp):

1. Caused by java.lang.NullPointerException: Attempt to invoke virtual method 'void com.unity3d.player.f.a(android.view.SurfaceView)' on a null object reference

also I can see same reports from Google Play Console.
there are not specific devices or regions or device state of ram or free storage that points to hint where crash occurs.
projects are using last firebase, google ads and facebook plugins
pls help!

 

We're also seeing this exact issue. I don't have much further info except we do have one video report from a beta tester that shows the following:

• The user closes the game via in-game button (which calls Application.Quit)
• The application closes, device home screen shows for ~2 seconds
• The crash occurs

We're using Unity 2020.3.11f1. We recently upgraded from 2019.4.16f1 and did not see this crash before the upgrade

 

im using Unity 2020.3.9f1 and have same issue.any help?

 

I found something. All errors occur only in the armeabi-v7a library. There are no reports from devices using the arm64-v8a library. Checked all reports from Firebase Crashlytics and Google Play Vitals.

It also looks like this is a similar issue from another thread: https://forum.unity.com/threads/android-crash-on-unity-2019-4-26f.1116979/
But there the error comes from both libraries and when creating the surface

 

i found the solution.I've discovered that Nox Player can reproduce this error when calling Application.Quit().
so i try to create a plugin to extend UnityPlayerActivity and override onDestroy() funtion

Code (CSharp):

1. @Override protected void onDestroy ()
2. {
3.      mUnityPlayer.removeAllViews();
4.      mUnityPlayer.quit();
5.      super.onDestroy();
6. }

after that,I no longer get that error on Nox Player

 

We also experiencing a surge of this crashes with upgrade to unity 2020.3.12f1, which is happening after Application.Quit() and possibly when app gets killed in background on some devices.
Did anyone find a viable solution besides creating a plugin and overriding UnityPlayerActivity?

 

Can you share this plugin/library with us? I also want to test it, but I don't have "Nox Player".

 

We're preparing a build for a small staged rollout in which we've changed the android behaviour to move the app to the background rather than quitting. It's not ideal but the app closes and the player can swipe it away from the background to close it manually.

We're not sure if the crash is occurring when the app is killed in background by the system (as @romannotroman ) suggested it may, but this "fix" will likely not help much if that's the case.

I'll post the code below and update this thread once we've got some results back as to whether the change helps the crash report numbers

Code (CSharp):

1. using (var unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
2. {
3.     using (var activity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity"))
4.     {
5.         activity.Call<bool>("moveTaskToBack", new object[] { true });
6.     }
7. }

 

NoxPlayer is free,u can google it.
This is my plugin,Unity forum not allow to upload aar file so after download,make sure you rename it to .aar
You can use my plugin because it very simple,only override onDestroy on UnityPlayerActivity and nothing else
Put this .arr file to Plugins/Android,and make sure you set

Code (CSharp):

1. activity android:name="com.HD43.CUL.UnityPlayerActivity"

on yout AndroidManifest (dont worry,it not change your final package name)
after use this solution,I no longer see this error on firebase reports

 

I tried this code instead of Application.Quit, and the issue stil occurs.

 

Edit: Disregard my comment below, report numbers seem to have dropped but we're definitely still getting crash reports come through.

Just reporting back to confirm the "fix" I mentioned above has seemed to completely prevent the crash being reported in our project, despite it not working for @Shefich . Hopefully this may be useful to someone else.

Either way, lets hope Unity can diagnose the problem and get a fix out soon for 2020 LTS

 

Lots and Lots of the same crash here.

Hi all. Have same problem after updating from Unity 2018.4.23 to Unity 2020.4.3.
Planned to update to 2020.3.12, because it release notes it says that the Applicatio.Quit crash has been fixed. But @Zeeppo-Games said that they have same issue on that version.
So what to do?

Crash stacktrace,

This is my override Acctivity

I'm using Unity 2019.4.28f1 and have same issue. Any progress on this issue?

 

Same problem here.

I can now also confirm that upgrading to unity 2020.3.13f1 does not fix the crash despite the 2020.3.12 release notes mentioning they fixed a crash related to Application.Quit() on android.
The issue linked in the release notes is actually a separate problem about a seg fault.

 

No fix in 2020.3.14f released yesterday.

Unbelievable

 

Hey i have downgraded to Unity 2020.3.3, and problem gone. now waiting for fix, most likely on 2020.3.15.

 

Is there any issue created for this crash? Or any place we can vote? I didn't see any related pages like this one neither in the forums nor in the issues pages.

 

I'm waiting for the fix. I hope it happens soon.

 

Just following up with our solution for the time being. As @HD43 suggested, overriding the

UnityPlayerActivity.onDestroy

logic seems to prevent the crash.

I tried the following:

• Extended the

  UnityPlayerActivity

  class and overrode the

  onDestroy

  method.
• Copied the

  UnityPlayerActivity

  class directly from the source, and changed the

  onDestroy

  code implementation directly.
• Used the .aar file uploaded by HD43 in the post above.

However, all of these attempts had other issues, such as our device-orientation would no longer lock to landscape-only.

What did work for our project was directly manipulating the resulting

UnityPlayerActivity.java

class file after the gradle project is generated.

I've posted the code below...

Code (CSharp):

1. #if UNITY_ANDROID
2. using System.IO;
3. using System.Text;
4. using UnityEditor.Android;
5.  
6. public class AndroidBuildPostProcess : IPostGenerateGradleAndroidProject
7. {
8.     public int callbackOrder => 999;
9.  
10.     public void OnPostGenerateGradleAndroidProject(string path)
11.     {
12.         // src\main\java\com\unity3d\player\UnityPlayerActivity.java
13.         var activityClassPath = Path.Combine(path, "src", "main", "java", "com", "unity3d", "player", "UnityPlayerActivity.java");
14.         var activityClassText = File.ReadAllText(activityClassPath);
15.  
16.         var methodIndex = activityClassText.IndexOf("protected void onDestroy");
17.  
18.         var methodBodyIndex = activityClassText.IndexOf('{', methodIndex);
19.         var methodEndIndex = activityClassText.IndexOf('}', methodBodyIndex);
20.  
21.         var sb = new StringBuilder(activityClassText.Length + 100);
22.  
23.         sb.AppendLine(activityClassText.Substring(0, methodBodyIndex + 1));
24.  
25.         sb.AppendLine("mUnityPlayer.removeAllViews();");
26.         sb.AppendLine("mUnityPlayer.quit();");
27.         sb.AppendLine("super.onDestroy();");
28.  
29.         sb.Append(activityClassText.Substring(methodEndIndex));
30.  
31.         File.WriteAllText(activityClassPath, sb.ToString());
32.     }
33. }
34. #endif
35.  

 

Thanks, @jperryoddgames I will try this.
Is any unity dev going to comment on this? It's been going on for a while, this is not really great for an LTS build.

 

it's seem a nice solution.i'll try it soon,thanks for your suggest

 

I also have this issue here in one of my devices, it happens 100% of the time...

 

is it fixed for LTS Release 2020.3.15f2?

 

Must be. Please let us know if you will test it.

 

2020.3.15f2 seems to have fixed it!

 

Same problem on 2020.3.16f1 LTS

 

Same problem on 2021.1.22f1

 

Same problem on 2021.1.24f1

 

same problem here on 2019.4.31f1

 

same problem on 2020.3.21f1
