Steps to reproduce:

Add the following code to the custom Application class to observe the mentioned violations in the log:

    override fun attachBaseContext(base: Context?) {
        StrictMode.setThreadPolicy(
            StrictMode.ThreadPolicy.Builder()
                .detectAll()
                .penaltyLog()
                .build()
        )
        super.attachBaseContext(base)
    }

Thanks for reporting, @alexey-rabets. I was able to reproduce the same issue. I'll notify an engineer to see what we can do here. Thanks!

Crashlytics relies on these disk reads because of the way it ensures all information captured during the last crash is processed and uploaded properly. These disk reads don't happen on the main thread so shouldn't affect your app in any significant way, unless a crash loop is detected. You can avoid the verbose log output by calling permitDiskReads() on the strict mode builder.

It looks like all these file IO operations captured by StrictMode are performed on the main thread on every cold app start even if there were no crashes and may potentially affect apps. For the example given in this issue, reported duration of these operaitons on the main thread is about 130 ms.

The file operation is part of a check that Crashlytics does to ensure the app has launched successfully. This increases reliability of crash reporting for apps that crash on launch. We are considering alternative approaches that would avoid the disk read violation. Internal tracking for feature request b/256604997.
