Dart-code: Debug Console window unusable while showing ads on emulator

[JCKodel]

My Android emulator often shows a E/eglCodecCommon(21959): glUtilsParamSize: unknow param 0x000085b5, specially for web contents.

While showing an ads banner (plugin firebase_admob), the debug console keep showing thousands of this error:

It would be nice if there is a setting for us to filter what kind of log we want to see. For example, in settings.json:

"dart.filterDebugWindow": ["eglCodecCommon", "Ads"]

Would filter those lines while debugging:

It would be nicer if we could colorize it (E/ in red, I/ in blue, W/ in orange, etc.)

@devoncarew @pq does IntelliJ already do anything to filter things like this? I can add a customisable filter, but it'd make sense to have the same behaviour if we can (though we may be more restricted in VS Code, for ex. not being able to add any nice UI around the debug console).

[devoncarew]

We don't have a feature like this, but a natural place to put it would be somewhere in the run / debug consoles. But, perhaps these extremely noisy messages are rare? Is there some other fix we (or the flutter plugin) should apply?

[DanTup]

Ok, I looked into this more - it seems that Flutter takes the raw logcat output, but filters it to only include certain messages:

https://github.com/flutter/flutter/blob/2449928d7ca4ae1bde00694627b2099417d6a5e6/packages/flutter_tools/lib/src/android/android_device.dart#L840

I can't understand why all of the above would get through though - it doesn't seem like it matches any of the patterns (there are some exceptions, like during a fatal crash - but it doesn't seem like that should trigger here either).

@JCKodel can you reliably reproduce this? Can you give me instructions for exactly what you're doing to see if I can repro here? Thanks!

1) flutter create log_test
2) Added firebase_admob: ^0.9.0+7 to pubspec.yaml
3) Added <meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="ca-app-pub-0592784782375028~9340585015"/> to Android manifest (inside <application/>)
4) Put FirebaseAdMob.instance.initialize(appId: "ca-app-pub-0592784782375028~9340585015"); inside main (you'll have to manually import the package because VSCode refuses to find the import automatically (see https://github.com/Dart-Code/Dart-Code/issues/1926)).
5) Insert this code anywhere before main:

MobileAdTargetingInfo targetingInfo = MobileAdTargetingInfo(
  keywords: <String>['flutterio', 'beautiful apps'],
  contentUrl: 'https://flutter.io',
  childDirected: false,
);

BannerAd myBanner = BannerAd(
    adUnitId: "ca-app-pub-0592784782375028/4212381411",
    size: AdSize.smartBanner,
    targetingInfo: targetingInfo,
    listener: (e) {
      if (e == MobileAdEvent.loaded) {
        myBanner.show();
      }
    });

6) Inside your build method, insert myBanner.load(); (I know this isn't the right place to do it, is just for testing)
7) Run the app on the Android x86 Emulator (the one that come with Android Studio. I'm using Nexus 5 with Google Play)

The app should initialize and an ad banner will be loaded at the bottom.

This is my debug output: Notice that there is usefull information (the error saying GoogleService failed to initialize), that's why I'm asking for a filter I think this kind of information should not be removed (catlog for our process is VERY usefull, but we need to filter spam messages).

BTW, my machine is a Windows 10 with GeForce GTX970 (running old drivers because nVidia nerfs performance in new drivers for old boards) and the emulator is run with this command line:

emulator -avd N -writable-system -shell -logcat-output con -gpu host

BTW: I also tried the above command without -logcat-output, the results remains the same.

After some minutes: https://gist.github.com/JCKodel/a5d9e4d750ce00a7460bbdcf6914a918

[DanTup]

Had a quick look at this again, trying to figure out why this stuff was logging despite not matching the regex:

E/eglCodecCommon(29898): glUtilsParamSize: unknow param 0x000085b5
E/eglCodecCommon(29898): glUtilsParamSize: unknow param 0x000085b5
E/eglCodecCommon(29898): glUtilsParamSize: unknow param 0x000085b5
E/eglCodecCommon(29898): glUtilsParamSize: unknow param 0x000085b5

Turns out there's also a regex for the process ID of the app on the device, and anything from that process ID (29898) in the log is also allowed through.

Although we could add a filter in VS Code, I think this may be better addressed in Flutter, since if you run flutter run from the terminal, you get all the same spammy output - and it feels like it's probably unwanted there too (at least if you're not running with -v). I've opened https://github.com/flutter/flutter/issues/42849 about this - it's not clear to me if the issue is with the plugin writing too much, or Flutter not filtering enough. I'll leave this open for now until there's some response there.

Hi Danny,
Just my 2 cents-worth here. I have recently implemented Firebase performance monitoring in my app and I now get the same warning messages constantly in the VSCode debug console. This makes it a nightmare when trying to debug using print statements to the console. It looks like there is no way to turn these off via Firebase - the following SO Q&A relates: https://stackoverflow.com/questions/55510223/firebaseremoteconfig-error-no-value-of-type-string-exists-for-parameter-key
Wish I never switched on performance monitoring :-(
It appears the only way people are getting around this is to use filter/folding option provided by Android Studio Logcat and pidcat. I don't use either of these so would be very useful to have some form of filtering in VSCode debug console.

[DanTup]

@GrahamDi I don't think filtering in VS Code is the ideal solution here - running from the terminal with flutter run will show the same verbose output. I opened an issue at https://github.com/flutter/flutter/issues/42849 about this, since I think it makes more sense for the default output to be less verbose so all clients (including terminal) have more reasonable output.

[GrahamDi]

Hi Danny,
Ok, thanks. Makes sense.

I will work on removing Firebase perf Monitoring and Remote Config from my app instead :-)

[erperejildo]

Any update? Still facing these messages

[DanTup]

@erperejildo see https://github.com/Dart-Code/Dart-Code/issues/1980#issuecomment-551523986.

[erperejildo]

@erperejildo see #1980 (comment).

but not updates on that, right?

[DanTup]

There haven't been any updates posted on that issue, but I don't know if the issue has been discussed by the team that works on that plugin. Subscribing to that issue is the best place for updates. It's difficult to fix directly in the VS Code extension as there's no ability to add filters to the UI nicely (that might be a reasonable VS Code request, but there was a previous request for a better logging API and it was dropped). Doing it with a setting that's a blacklist/regex may work, but it feels the wrong place to add it (since if it's spammy here, it will be the same for Flutter command line users).

I think the best option is if the plugin (or Flutter) generated less output when run in non-verbose modes, since that way running from the console would also improve.

[erperejildo]

I see exactly the same messages in Android Studio as well

[DanTup]

Yeah, that's why I think improving this in Flutter/the plugin is the best option.

Android Studio does have more flexible APIs than VS Code though, so if VS Code had a nice filtering API for the debug console, it might be possible that both editors could then add filters in their consoles (this would be give more functionality than simply removing the output from Flutter, since you could customize what you see). I'm not sure if VS Code is likely to get the ability to add filters though, I think it still aims to be a lightweight editor rather than a big IDE with all features.

[sjghose]

Just to add - I've tried using most of the admob plugins available including the firebase_admob, all have the same extreme verbose logging turned on by default. It's not a plugin issue - it needs to be filtered out in flutter itself.

[JCKodel]

Almost 7 months and everything stays the same... it's impossible to work with so many trash.

How hard would be to create a special "debug console" output panel? One with filter? It will be impossible to filter any possible extension from Flutter, so WE NEED FILTER ON VSCODE, it DOES make sense.

[DanTup]

How hard would be to create a special "debug console" output panel? One with filter?

Output to the Debug Console comes from the debug adapter using specific events ("OutputEvents"). These are not consumable by extensions in the client, so in order to show them in another panel we would need to send a copy of all of the output from the debug adapter. A better solution might be to send the filter into the debug adapter and filter it there (however that means it wouldn't show in logs etc. either).

Whilst that's not insurmountable, it's not clear that this would be the best solution. People using Flutter from the terminal are seeing this output too, so having it filtered in Flutter would solve the issue for more users.

Similarly, if it was to be handled in the editor, it would be much better for VS Code to have a filter in the Debug Console (like it does for Problems view, etc.) so that all languages/users can benefit from it rather than it being specific to Flutter apps.

I'm not against having something here, but I think implementing it in the extension here should be a last resort if it seems the other options aren't going to happen.

[DanTup]

Looks like there may be a filter coming to the Debug Console:

[DanTup]

I've also opened an issue about collapsing identical lines that I think would help too. Please 👍 !

https://github.com/microsoft/vscode/issues/104162

[DanTup]

The next version of VS Code (and current Insiders release) includes a filter in the debug console:

It's not a perfect fix, though there's still an open Flutter issue about the amount of logging from ads (https://github.com/flutter/flutter/issues/42849). I don't think there's anything to do in Dart-Code now though, so closing this as fixed upstream.
