created issue #1

Jul 13, 2018 08:58AM

Component used: Room
Version used: 1.1.1
Kotlin version: 1.2.51

Room can't detect the TypeConverter of a List<Model> if that Model itself is written in Java and if I convert this class to Kotlin, it works as expected!

I got this error no matter where I put the TypeConverters annotation!
error: Cannot figure out how to save this field into database. You can consider adding a type converter for it.

A project where this can be reproduced is attached!

Some more context regarding this issue: https://stackoverflow.com/questions/73417527/android-emulator-initial-network-call-delayed-by-several-seconds/

It's happening on 31.3.10. Reverting to 31.2.10 fixes the problem.

It seems like we can repro the issue with embedded emulator. I used a stopwatch to record how long it takes for Google Sign-In page to load for the first time.

1, stand-alone emulator version (31.3.10): 4 seconds

2, embedded emulator (31.3.10): 15 seconds.

I am using Windows 10 with Intel Core i7-11850H@ 2.50GHz with 32GB RAM.

Ranjit is also able to repro the issue on Windows with Intel CPU. The problem is essentially in the first network connection. I asked Ranjit to help me with bisection mentioned in #3.
