dbflow android insert data into sqlite database HD

One of the issues with existing SQL object relational mapping (ORM) libraries is that they rely on Java reflection to define database models, table schemas, and column relationships. DBFlow is one of the few that relies strictly on annotation processing to generate Java code based on the SQLiteOpenHelper framework that avoids this issue. This approach results in increasing run-time performance while also saving you from having to write a lot boilerplate code normally needed to declare your tables, manage their schema changes, and perform queries.
