Why can’t strictmode capture SQLite read / write operations?

In my app, I set the following settings for strictmode:

    StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
            .detectDiskReads()
            .detectDiskWrites()
            .detectNetwork()
            .penaltyLog()
            .penaltyDeath()
            .build());

At some point, I noticed that there are few places where I don't put SQLite operations in a separate thread, but they don't trigger strictmode violations. I have tested on real devices with Android 5.1.1 and genymotions with 4.4.4 and 5.1.1, and the results are the same. I recall that SQLite operations once triggered strictmode violations, But this is not the case now. Do you know why?

I see the following in the documentation:

Is that why?

resolvent:

SQLite is a library written in C, so all access to database files is indeed hidden in JNI calls
