Ok, I've been testing a game with several scenes. In Unity and iOS devices, everything works perfect. In Android, always crash (or freeze if you prefer).
I'm using Unity 2017.2.0f3. and the line of code that crash is the next one (nextScene is a string with the value of the next scene):
SceneManager.LoadScene (nextScene);
I've been trying other options like:
SceneManager.LoadScene (nextScene, LoadSceneMode.Single);
But this is not working neither. The last one I tried was:
SceneManager.UnloadSceneAsync(UIManager.Instance.currentScene);
SceneManager.LoadScene (nextScene, LoadSceneMode.Single);
Again without success. Please I really need help with this. I've dealing with this problem for 24 hours. It's driving me crazy.
After more than 24 hours I solve the problem. I hope that my solution help other people because there isn't enough references on the web.
When I created the APK file it was splitter with a second one of type OBB. This kind of files is required when the Android App is too big. In my case was set by default.
The solution was to force the creation of the APK without the OBB. To do that you must get to Player Settings in Android, go to Publishing Settings and uncheck Split Application Binary (located at the bottom).
Everything's working now and life is good again.

I really need some help. I was rearranging file locations and trying to clear up some space and somehow broke the ability for Unity to operate on my laptop. The pictures of the errors are below.
This all started when I was moving a completely functional unity project from an external SSD to my internal laptop SSD. I had to clear space for the size of the project and I must have deleted something important, but I have no clue how to tell what it is.
Error seen when opening project
Editor view after opening
Error when trying to attach a script to a GameObject
Error in editor log
Steps I've taken:
I've restarted my computer several times.
I've completely uninstalled all editor versions and the unity hub (twice), including deleting all local app data for unity, emptying the temp bin, and clearing the keys in the registry.
I've started completely new projects, checked
old ones that used to work, downloaded sample ones from unity learn
just to make doubly sure that it's not me being dumb.
My current theory is that this has to do with me clearing some data from a National Instruments folder. I'm new to programming and just read online that these drivers are needed for .NET communication, but would this be why Unity keeps failing then?
This has all taken more than a few hours and I'm struggling to fix this if anyone has any suggestions, please. I'd really appreciate any insight.
Update: I'm able to make new scripts, objects, scenes, etc. but I can't attach any script components to game objects because "the script class can't be found"
Update #2: Checking the Editor logs shows that the Tundra build is failing, and the "93 items updated" matches the 93 errors that are shown. No idea what Tundra is, but that's something to look at now!
Update #3: fairly more certain it's something to do with the .NET interactions, but I'm completely unknowledgeable about this and worried about breaking this further
Answering my own question in case another person finds this and has the same issue, but the problem wasn't .net related or anything I mentioned. I uninstalled anaconda which caused some issues with the Command Prompt, where it would close immediately after opening. Unity uses this for a number of processes, so that's what caused all the blank errors.
The solution is to delete the Microsoft Command Processor AutoRun key in the registry editor.

Cmd crashes with exit code 1 after uninstalling anaconda
I have a Samsung Galaxy Tab Active 1, on the latest version of android it can handle, and just recently, after adding accessibility features that shouldn’t affect anything, the balls in my game stopped updating. I instantiate a ball, and change a few properties on it, and then for some reason I think it’s not calling the update method. There are no errors.
I’ve heard using PrefabUtility to instantiate might help, but I haven’t done that just yet. I will update if PrefabUtility works.
Any advice?
Whoops, this was due to me being a bit stupid. The main reason it was happening was because of a parsing error in some of the accesibility settings, as they were not saved correctly due to weirdness I can't wrap my head around with files in Android. TLDR: file did not save correctly, and so did not load correctly, and so data messed up, and so it errored before it could do anything.
I am using Unity version 2018.3.6. I have the 2D extra assets. The problem is that every time I try to place down or remove a tile, the editor crashes. After I run Unity again and go into play, there are no crashes.
I need help on this. I tried removing the extra assets but it didn't work. I have spent many hours trying to figure out what's wrong with the system.
The app runs fine in the editor, but when I run it on a device I get two errors:
java.io.FileNotFoundException : assets/build_info.txt
and then a error from my loading method that says the scene main_menu could not be loaded because its not in the build settings(it is);
What is this build_info.txt that I have never heard of before and why did it suddenly go missing after I imported the google OBB downloader plugin?
UPDATE : The problem seems to be connected to the split application binary option, since without it the app builds fine. Problem is I have to use it since its bigger than 50 mb.
UPDATE 2 : The problem magically fixes itslef after the device is restarted. This happens on multiple devices, even if the game is downloaded from the google play store.
For some reason removing the maxSdkVersion attribute from the <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> tag in the manifest solved the issue.
this might help
maybe you didn't add the scene into the build settings . thats why current scene is running on the editor but the build game is not running !
goto file-> buildSettings -> add the scene on the top box
or click the add current button.
the scene at 0 position will be loaded first !
My game is crashing whenever I switch scenes and then press play in the editor. I am using this code to switch scenes:

I have tried disabling most of the scripts in my game to debug the problem but it freezes every time. I've also tried loading the levels without the co-routines but that doesn't help. I can continue playing the game as long as I don't use the editor controls, however things get pretty choppy and performance becomes terrible.
First, look at the editor logs, quite possible that the reason of the crash will be there. If unsure, post them here (post on gist and link here).
Also, if you have unity pro (or a trial version of pro), try looking at the profiler's readings. On free you can also try looking at the Stats button from the Game window. Using too much memory (RAM or VRAM) can cause crashes.
i was also having same problem. if your program is correct then just change the editor path to anything in unity hub and save, close unity hub, open again and set the path to previous one.
