ToOne<T> or ToMany<T> relation is null
See original GitHub issueI have tried to run the exmaple project in AndroidStudio and it works perfectly. However, I want to try the java-plain testing project in IntelliJ again and here is the source code.
It can build successfully, but I encountered a NullPointException
like #205 , because of ToOne<Note>
and ToMany<Note>
are both null.
I feel so much confused.

@TKolbusz Android Studio does this by default.
Anyhow, if you are writing a plain Java project (like op) I recommend using IntelliJ IDEA instead as Android Studio is optimized for Android projects. -ut
@greenrobot-team You are right. I found the cause of the problem. Thank you
