I have made a simple repo : https://github.com/lucianparvu/MauiApp16.App starting from animals samples and i receive out of memory too in Android without accesing API just a simple list .

It is a critical bug for me , preventing to go live with the application.

It is there something i can do ? It is something wrong with what i have done ?

Thank's

Hi @lucianparvu. We have added the "s/try-latest-version" label to this issue, which indicates that we'd like you to try and reproduce this issue on the latest available public version. This can happen because we think that this issue was fixed in a version that has just been released, or the information provided by you indicates that you might be working with an older version.

You can install the latest version by installing the latest Visual Studio (Preview) with the .NET MAUI workload installed. If the issue still persists, please let us know with any additional details and ideally a reproduction project provided through a GitHub repository.

This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

This simple repo it seems not to crash in .net 8 preview, at least for 10 min of testing, but the real application crash . I will make some changes and come back.

Log for Crashing : https://github.com/lucianparvu/Files/blob/main/LogMaui8

I have notice that the memory is increasing .... , i dont know if is normal for this simple app to go in 10 min to 680 MB.

@jonathanpeppers thoughts?

I can give in private some sample source code 8 version.

jonathanpeppers commented 1 year ago

Can I run the linked sample to see the problem? https://github.com/lucianparvu/MauiApp16.App

Or are we now talking about two different issues?

Hello,

This simple repo is in .NET 7 https://github.com/lucianparvu/MauiApp16.App and it crashes if you go back and forword for a few minutes and you will see memory will increase and in the end crash

The same simple repo upgraded at .net 8 didnt crash after the same period, but the memory increased from 100 MB to 700 MB in a few minutes of back and forward

My real application crashes in .NET 7 and .NET 8 too . I can send a sample in private .

jonathanpeppers commented 1 year ago

There are various memory leaks that are solved in .NET 8, so it makes sense the behavior you describe.

So, the only issue in .NET 8, is you'd like the sample to use less memory?

We can talk about the second app after looking at the first one.

lucianparvu commented 1 year ago

So, the only issue in .NET 8, is you'd like the sample to use less memory?

In .NET 8 in a real app with services, api, etc i get a crash too !!! I dont get a crash in this simple app .

Can use as mutch memory it wants, if i dont get a crash :))

Give me please an email where to send the real app sample in .NET 8, where you can see you will get crash .

jonathanpeppers commented 1 year ago

The above sample, one issue is how large the images are:

Some of these are 720x480 and placed in a tiny CollectionView row. Can you use thumbnail images instead for this? Something that is sized the same (or close) as the row's size, for example.

If you are getting a crash, what is the crash? You can use adb logcat to save a log.

Example:

# enable extra Mono logging
adb shell setprop debug.mono.log default,debugger,assembly,mono_log_level=debug,mono_log_mask=all
# clear the log
adb logcat -c 
# cause the app to crash
# save the log
adb logcat -d > log.txt

And then log.txt should contain information as to what happened, can you share it here? Thanks.

lucianparvu commented 1 year ago

This is the log i saw in VS at that time : https://github.com/lucianparvu/Files/blob/main/LogMaui8

This is homepage from real app : https://github.com/lucianparvu/Files/blob/main/HomePage.xaml

This is DetailPage from real app : https://github.com/lucianparvu/Files/blob/main/ProductCategoryDetailPage.xaml

I will try to to use adb logcat and come back

jonathanpeppers commented 1 year ago

The log from VS will not have the info we need. Can you get adb logcat output?

lucianparvu commented 1 year ago

If i run those commands when i start the app it seems the log is written only at the beginning, i have used them when the application crashed and display: Isnt Responding ... Close app / Wait.

Did you run this one?

adb shell setprop debug.mono.log default,debugger,assembly,mono_log_level=debug,mono_log_mask=all

There should be monodroid-assembly messages like:

07-07 08:33:25.695 18759 18759 D monodroid-assembly: assembly_store_open_from_bundles: looking for bundled name: 'System.Private.CoreLib' (hash 0x6b0ff375198b9c17)

Yes, of course.

How this should work ? It will write to log all the time ? because if i run those commands at the beginning i cant see there more logs, only initial logs, if i run them when the app crash you have that log.

lucianparvu commented 1 year ago

Can i send u source code on your email ? jonathan.peppers@gmail.com it is correct ?

Thanks

jonathanpeppers commented 1 year ago

Does adb shell 'getprop | grep mono' show the value is what you set?

I wonder if you are debugging the app from VS, and it overwrites the value?

lucianparvu commented 1 year ago

I took the log from Device Log cu copy paste , may this helps

https://raw.githubusercontent.com/lucianparvu/Files/main/log.txt

jonathanpeppers commented 1 year ago

Is the above log from Visual Studio? It doesn't look like logcat.

Some of the messages like this are expected when you enable the extra logging:

typemap: unable to find mapping to a managed type from Java type 'java/util/Collections$UnmodifiableCollection$1' (hash 0x151b978993453376)
jonathanpeppers commented 1 year ago

I tested @lucianparvu's real app (over email).

One thing I found are several .svg files like this:

<svg width="800px" height="800px"

Which are resized to 3200x3200 in for xxxhdpi on Android. These look like small icons that probably don't need to be any larger than 200x200 (and could maybe even be smaller). You can set BaseSize in your .csproj to limit how large .svg files are resized to.

I was already planning to make a build warning for this situation, but I will investigate other issues in this app.

jonathanpeppers commented 1 year ago

Beyond the .svg issue, I am able to see a memory leak in @lucianparvu's app, after navigating to a new page and back the new page lives forever.

In this example, I navigated 5 times (and sprinkled some GC.Collect() calls in the app):

Still investigating what is going on here.
