Why am I seeing EGL_emulation app_time_stats in the log when running on an Android 12 emulator?

Question

When testing a Flutter app on an emulator running Android 12, I'm seeing lines like these in the logs at regular intervals (approximately every second):

D/EGL_emulation(32175): app_time_stats: avg=312.93ms min=133.69ms max=608.57ms count=4

What do they mean, and how do I turn them off? I've never seen them on Android 11 emulators, so I'm guessing it has something to do with Android 12?

Any solutions to this? I tried using Android 12 on my new Apple Silicon Mac, and I ma seeing these too. – Undercool

Did you solve this? I see this since the update now in my RUN console window, so the other answers suggesting to edit the LogCat window don't really apply unfortunately – Coolish

Anyone has a clue what is the meaning of these logs? – Hobgoblin

Answer 1

Just click on this line then it will be filtered

Answer 2

• Right click on D/EGL_emulation ... in your RUN console window
• Click "Fold Lines Like This"
• Edit the filter that's just been added to only contain D/EGL_emulation.
• All these lines will be removed from the RUN console window now

the only valid answer for Run window – Hunt

it's not working – Tweeter

Where are these fold expressions saved now? If I want to clear them how to? – Kiri

2023 not working – Ichnology

This is not a real solution, because it depends on a functionality of the IDE which is sometimes not given, i.e. when using Neovim. – Mickel

Answer 3

All these EGL_emulation messages are very annoying, indeed. My solution so far is to create a custom logcat filter.

You can open the logcat filter configuration by clicking on the drop-down far right of the logcat-toolbar and select Edit Filter Configuration. You have to set two regular expressions:

• ^(?!(EGL_emulation)) in the Log Tag field filters all messages with the "EGL_emulation" tag.

• ^(?!(\?)) in the Package Name field filters all messages from apps without debug information. This is not as good as the Show only selected application filter, but the closest thing to a similar behavior so far.

Here is also a screenshot of my config, just in case the text is unclear:

However, I really hope this problem is fixed upstream as soon as possible ;)

This answer works, but the fact that it is a filter that you have to use instead of "show only selected application" and you have to manage it yourself now - its not great. The annoyance of using @Jammo's answer and still getting "XX internal lines" at the end of every other log message - is still better. – Clearcut

Thanks for this, driving me crazy as well. Android studio & XCode both feel like relics from 1999 vs a modern terminal+vscode workflow. I've looked really hard but can't find the drop-down. There's one by the top logcat tabs but it only has Show Toolbar, View mode, etc. There's a - button next to it that minimzes the toolbar. Below that I can favorite my quick filters, but again no configuration is available... – Foxtrot

Answer 4

These are messages from the Android emulator and can be helpful in some situations. I would suggest only filtering out the Debug messages, and not the Warning or Error messages as those may be useful.

Prefix:

• D/ - Debug
• W/ - Warning
• E/ - Error

For Android Studio Logcat logs:

• Use the method recommended in Torben's answer in logcat but modify to ^(?!(D/EGL_emulation)) so that Warnings and Errors will still show.

For VSCode Debug Console logs:

• Simply use a Filter exclusion string as !D/EGL_emulation.

At least on Android Studio Bumblebee 2021.1.1 it seems like the prefixes are not part of the tag/message, so i could not include them to the regex – Herby

Same, this solution doesn't work. – Hyperform

Answer 5

In Android Studio Electric Eel add -tag:EGL_emulation in the filter line like this:

Answer 6

In VSCode, with the debug console tab open, go to the filter (bottom right side) and set the following: !D/EGL_emulation

Answer 7

On the newer Android Studio[Giraffe], now you can right-click on the line and select "Ignore Tag " which will hide it from the logcat.

How do you undo ignoring a tag this way? Where can I configure or reset those ignored tags? – Assuming

I found where: Android Studio > Settings... > Tools > Logcat > Ignore tags. – Assuming

Answer 8

I was having difficult understanding how to use the new LogCat and filters in Electric Eel and here is how I got rid of the EGL_Emulation lines:

I needed tags with Crypton or (|) MainActivity | package:mine and (&) not (!) egl_emulation:

tag:Crypton | tag:MainActivity | package:mine & !EGL_emulation

This works great and shows you how to have multiple tags and how to use logical conditions.

Here's what it looks like in AndroidStudio
