FloorPlan & Room

The Room persistence library provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.

Room can export your database's schema information into a JSON file at compile time. To export the schema, set the room.schemaLocation annotation processor property (or kapt, if you use Kotlin) in your build.gradle file.

The JSON schemas can, then, be passed to FloorPlan as an input parameter for its rendering generation. Here we see an example with FloorPlan's Gradle Plugin:

android {
    ...
    defaultConfig {
        ...
        javaCompileOptions {
            annotationProcessorOptions {
                arguments += ["room.schemaLocation":
                             "$projectDir/schemas".toString()]
            }
        }
    }
}

...

floorPlan {
  schemaLocation = "$projectDir/schemas".toString()
  ...
}
