Demo Android app using Apache Cayenne ORM framework

This is a demo Android app that uses Cayenne ORM. Cayenne 4.0.B2 is used in this demo. Min Android SDK version is 19 (Android 4.4).

Customizations done

Following parts where modified/added in order to launch Cayenne runtime:

Custom resource locator that can handle Cayenne XML files loading from Android assets (it uses custom URL schema + handler hack)
Network activity is explicitly allowed on UI thread (see AppModule class) as Cayenne temp-id generator looks up local host address (maybe this should be changed in Cayenne).
Custom SchemaUpdateStrategy (see UpdateSchemaStrategy class) that allows to compare and migrate DB structure on every start (Uses existing cayenne-dbsync module).

Dagger 2.13 is used as a DI framework
slf4j-android 1.7.25 - binding of slf4j to Android logging
Additionally this project requires SNAPSHOT version of sqldroid SQLite JDBC driver. You can clone https://github.com/SQLDroid/SQLDroid and build it from sources, no modifications required.
