Android Work Manager: "Could not instantiate Worker"
This is a known issue with WorkManager 1.0.0-alpha09 that is already marked as fixed for alpha10.
As a workaround, you can add the following lines to your proguard configuration:
-keepclassmembers class * extends androidx.work.Worker {
public <init>(android.content.Context,androidx.work.WorkerParameters);
}
I had the same issue. The cause of the issue for me was that my Worker class was a nested class. The moment I made it an independent class, it worked.
