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?

Solution 1

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 ;)

Solution 2

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.

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

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

Same, this solution doesn't work.
