QUESTION
There are quite a few questions with the above error, but most of them are related to eclipse, for me it's happening in android studio and also for the project which was working fine till now.
My android project was working fine all the while, and then all of a sudden started getting this build error. Don't know where exactly is the issue, but I see some traces of greendao mentioned in the logs.
FAILURE: Build failed with an exception.

QUESTION
I'm using the PagingLibrary and also implemented the PositionalDataSource, I'm not using Room in this case since my DB was already declared by other developers and I don't want to migrate to Room right now. Instead, it is using GreenDao as a wrapper to Sqlite3.
The issue is that whenever I'm adding/removing/updating an item in DB the view is not updating. even if I'm calling to invalidate the DataSource.
