How to access generated logs in an Android application?

Question

I am using MetroLogger to generate debug logs in a MAUI application.

I am able to retrieve the logs when running the Windows app but not the Android one. I have tried on a physical phone and on an Emulator with no success. I have searched for documentations but did not find any relevant information about this.

Here is my configuration code:

    builder.Logging
    .AddTraceLogger(
        options =>
        {
            options.MinLevel = LogLevel.Trace;
            options.MaxLevel = LogLevel.Critical;
        }) // Will write to the Debug Output
    .AddInMemoryLogger(
        options =>
        {
            options.MaxLines = 1024;
            options.MinLevel = LogLevel.Debug;
            options.MaxLevel = LogLevel.Critical;
        })
    .AddStreamingFileLogger(
        options =>
        {
            options.RetainDays = 2;
            options.FolderPath = Path.Combine(
                FileSystem.CacheDirectory,
                "MetroLogs");
        });

    var path = FileSystem.CacheDirectory;
    builder.Services.AddSingleton(LogOperatorRetriever.Instance);

FileSystem.CacheDirectory is equal to

/data/user/0/[appcompanyname]/cache

But where should I find that folder ? I have tried:

C:\Users[username].android\avd\pixel_5_-_api_34.avd

Thanks for any help with this

It's not on your device, it's on your phone or emulator. You need to access it on that. The path is the exact path- on that device. You can use adb pull <path> to pull the file, or you can use Device Explorer in Android Studio to access it. I'm sure if you're using Visual Studio there's a similar utility.
