[SOLVED] WorkManager cannot inject with hilt in dynamic module

WorkManager cannot inject with hilt in dynamic module

When I use WorkManager + Hilt in regular module, the app works well. However, when I use in dynamic module, meeting the below issue

java.lang.NoSuchMethodException: <init> [class android.content.Context, class androidx.work.WorkerParameters]
    at java.lang.Class.getConstructor0(Class.java:2320)
    at java.lang.Class.getDeclaredConstructor(Class.java:2166)

Solution

I found solution from this answer Using DelegatingWorkerFactory

It seems Hilt hasn't supported annotation in dynamic module yet. So I must create the factory and add this to DelegatingWorkerFactory. Register DelegatingWorkerFactory in application.
