How to use the ORMLite query builder to get the total records in a table
ORMLite has a Dao.countOf() method that returns the total number of rows in a table:
long numRows = dao.countOf();
You can also count the number of rows in a custom query by calling the countOf() method on the Where or QueryBuilder object.
// count the number of lines in this custom query
long numRows = dao.queryBuilder().where().eq("name", "Joe Smith").countOf();

for package 5: you can use countOf()
From the docs:
Returns the value returned from a SELECT COUNT(*) query which is the number of rows in the table. Depending on the database and the size of the table, this could be expensive.
