I opened up my project and compiled and ran it, and I'm getting the error mentioned in the title, error: cannot find symbol class ComputableLiveData. I've built a local database using a Room abstraction over SQLite, and the error is occurring in BundleDao_Impl.java.
package com.weaberlumber.programmer.s4s_scan;
import android.arch.lifecycle.ComputableLiveData; //The error is here
import android.arch.lifecycle.LiveData;
import android.arch.persistence.db.SupportSQLiteStatement;
import android.arch.persistence.room.EntityDeletionOrUpdateAdapter;
import android.arch.persistence.room.EntityInsertionAdapter;
import android.arch.persistence.room.InvalidationTracker.Observer;
import android.arch.persistence.room.RoomDatabase;
import android.arch.persistence.room.RoomSQLiteQuery;
import android.arch.persistence.room.util.StringUtil;
I've tried deleting the build folder so that the file could be regenerated, but no luck.
This was fixed by adding the following implementation to the dependencies under build.gradle (Module: app)
implementation 'android.arch.lifecycle:livedata:1.1.1'
