I ran into problems with this and filed this feature request, so AFAIK as of 1.0.0-alpha3 this is still not possible. – Gwyn

@Gwyn thanks. if you post it as answer, i will accept it. – Sororicide

Added comment in the feature request, @Gwyn did you get any news about it other than the comments in the feature request ? – Complemental

@JoseF: No, sorry. – Gwyn

I see that it was upgraded from Priorty 3 to Priority 2 on Nov. 28, 2017 – Purview

Answer 1

AFAIK, as of 1.0.0-alpha3, this is not possible. Room wants fields; AutoValue doesn't expose fields. Keep tabs on this feature request for progress in this area.

Answer 3

Released in 2.1.0-alpha01!

Note that you have to add the @CopyAnnotations annotation for it to work

Auto Value: Room now supports declaring AutoValue annotated classes as entities and POJOs. The Room annotations @PrimaryKey, @ColumnInfo, @Embedded and @Relation can now be declared in an auto value annotated class’ abstract methods. Note that these annotation must also be accompanied by @CopyAnnotations for Room to properly understand them.

Following this task, apparently they added support. I assume it will be possible in the future Room release (probably androidx.room version 2.0.0). Still not merged as part of 2.0.0-beta1 though

Answer 5

Now it is possible with the Room database 2.1.0.

You can make this possible by annotating the abstract class methods with @PrimaryKey, @ColumnInfo, @Embedded, and @Relation. The abstract class has to be annotated with @Autovalue.
