Question Lagging and Crash for Android

Hello,
I make book app in unity. I have a performance problem. My book app has 300+ scenes and every scene has only one TMP, one next button, one previous button. I save the last scene index number read to playerprefs. My book app is getting very slow after 100. scene and getting closed. I deleted all of buttons and TMPs. I create 150 scenes as empty but I faced same problem. There is no problem when it runs on my Unity editor. There is a problem when I install it to my phone. My phone is Samsung S10 Plus and Android 10. I think, it is caching somethings this is why my book app is geting slow and getting crash. But I couldn't find why is. What can I do to solve this problem? Could you please help me? Thanks.

Sincerely,
Cem Erman

 

Are you loading all of the scenes at once?

 

No, User switches to the next scene after reading.

Transitions between the first 20 pages are fast. After that, it starts to slow down. It shuts down after page 100.

 

Try using the Profiler with a mobile build. I'd suspect you'll see memory usage continuing to increase. If so, you'll want to see what exactly is using the memory. Might need to do deep profile, or try the memory profiler package.

https://docs.unity3d.com/Manual/ProfilerMemory.html

Deep profiler is very memory and performance intensive in the Editor, so I don't recommend just letting it run or using it while running the game in the Editor. Just use it at different points to analyze what it going on at that time.

 

Hello, Thank you so much for your interest. Deep profile worked in editor mode but unfortunately I didn't understand datas. Screenshot is attached.

 

Hello,
I will make suggestion you said. I will give information about result. Thank you so much for your support and interest.

PS : I added text every page manually as TMP

 

Hello Martin,
I tried to make things you said. I hope I have done correctly. My profile analysis data is attached. Unfortunately, I didn't understand nothing

Test Scenario :
First test was very fast till 50-60 pages and crashed at 128. page
Second test was very slow and I think it crashed at between 70-90 pages.

When I test I clicked next button fastly and again previous button. My app has only text this is why I trought that my app should work fast.

Thank you so much for your support. I am grateful for your help.

 

Hello Martin,

I deleted all of app and I created 2020.1.11f but I faced same problem and deleted it. I created in 2019.3.6f again.
I found the problem. I disabled Admob Banner script and my app worked perfectly but I enabled admob banner script again, my app has a performance problem is going slow down and crash. Unfortunately, I couldn't find a solution. The script I used is standart admob script. When I add banner object every scene and my book app is going very slow down and crash. Could you please give me a suggestion?

I added Google Mobile Ads 5.4.0
My unity version : 2019.3.6f

Thank you so much for your support.

Admob Banner Script:
//using System.Collections;
//using System.Collections.Generic;
//using UnityEngine;
//using GoogleMobileAds.Api;
//using System;

//public class BannerReklam : MonoBehaviour
//{
// private BannerView bannerView;

// // Start is called before the first frame update
// void Start()
// {
// //Initialize the Google Mobile Ads SDK.
// //MobileAds.Initialize(initStatus => { });

// this.RequestBanner();


// }

// public void OnGUI()
// {
// GUI.skin.label.fontSize = 60;
// Rect textOutputRect = new Rect(
// 0.15f * Screen.width,
// 0.25f * Screen.height,
// 0.7f * Screen.width,
// 0.3f * Screen.height);
// GUI.Label(textOutputRect, "");
// }

// // Update is called once per frame
// void Update()
// {

// }

// private void RequestBanner()
// {
// // These ad units are configured to always serve test ads.
//#if UNITY_EDITOR
// string adUnitId = "unused";
//#elif UNITY_ANDROID
// string adUnitId = "ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxxx";
//#elif UNITY_IPHONE
// string adUnitId = "ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxxx";
//#else
// string adUnitId = "unexpected_platform";
//#endif

// // Clean up banner ad before creating a new one.
// if (this.bannerView != null)
// {
// this.bannerView.Destroy();
// }

// AdSize adaptiveSize =
// AdSize.GetPortraitAnchoredAdaptiveBannerAdSizeWithWidth(AdSize.FullWidth);

// // Register for ad events.


// this.bannerView = new BannerView(adUnitId, adaptiveSize, AdPosition.Bottom);

// AdRequest adRequest = new AdRequest.Builder()
// .AddTestDevice(AdRequest.TestDeviceSimulator)
// .AddTestDevice("0123456789ABCDEF0123456789ABCDEF")
// .Build();

// // Load a banner ad.
// this.bannerView.LoadAd(adRequest);
// }


//}
