DiskRead and DiskWrite Violations in ChuckerCollector

[Alireza-Farahani]

✍️ Describe the bug

I'm not even sure its Chucker problem or not, but Creating ChuckerInterceptor instance (done by Hilt in out app) results in both DiskReadViolation and DiskWriteViolation.

💣 Steps to reproduce

StrictMode.setThreadPolicy(StrictMode.ThreadPolicy.Builder()
    .detectDiskReads()
    .detectDiskWrites()
    .penalty<whatever>
    .build()
)

🔧 Expected behavior

Getting no violation

📱 Tech info

• Device: Pixel 2
• OS: Android 11
• Chucker version: 3.5.2

📄 Additional context

Actually I traced those two violations and one is a simple File delete and the other a new SharedPref and I know it's not much an issue, performance wise.

Thanks for the report. I will try to reproduce this week and get to you.

Seems like we need to enable every single check in StrictMode to cover all use cases our users might have 🙂

Ok, I was able to reproduce and will work on fixing this issue.
