    Hello I'm making a 2D game for Android. My game weighs 60 MB but when you go from the menu to the level, the app crashes. In the phone settings, I found that the app used 12 GB of RAM when switching from one scene to another. There is no such problem on the computer. What might be the problem?

    sounds like you have a memory leak, you should use a memory profiler to try to identify it

    Thanks.
    Unfortunately, the memory profiler crashes with the app. the scene I'm uploading isn't too demanding. I don't know what the problem is yet.

    Definitely sounds like a memory leak.

    Delegates are usually the main culprit behind memory leaks. Do you maybe have any delegates/event subscriptions being created in a loop or within any of the

    functions in any of your scripts?

    Thanks for your reply. Can it depend on the animation in the loop? I will definitely analyze all the scripts. And I will answer.

    It can if the animation is calling a function that creates a delegate.

    Hi,
    Which version of Unity and which memory Profiler (i.e. Memory Module in the Profiler or Memory Profiler package) are you using?

    If you update to 2019.3.15f1 or 2019.4.x (version 2019.3.12f1 - 2019.3.14f1 are affected by this bug, I chimed in because I thought that that might be the issue you're hitting) you could try to investigate that with the Memory Profiler Package.

    Can a large sprite size be a problem.

    Please define large? Actually, no. I can't really imagine that being the case. I'd suspect the fault to be somewhere in your code.
    I can't really trouble shoot this through the forums for you, since I don't have any clue what is going on in your project. The Profiler and the Memory Profiler might be able to help getting some crucial background info, without which the best thing I can do here can be equated with pointing a very narrow lazer pointer blindfolded into the night sky and hoping to hit a star in our galaxy. Please try to use these tools, try to get as far as you can using the documentation I just linked to, just to narrow it down as far as possible and then I can maybe give you some further hints based on what you found.

    Thank you all, I solved the problem. The problem was that the scene had an animation consisting of 140 frames in full HD.
