QUESTION: 57 Topic: KOTLIN only

If you added to your build.gradle file a room.schemaLocation:
android {
defaultConfig {
javaCompileOptions {
annotationProcessorOptions {
arguments = ["room.schemaLocation": "$projectDir/schemas".toString()]
}
}
}
}

Then, you build your app or module.

As a result you got a json file, with such path to it: app/schemas/your_app_package/db_package/DbClass/DB_VERSION.json What are the correct statements about this file? (Choose all that apply.)

It’s a file with Room-exported schema
Main JSONObject in this file usually should contain a number "formatVersion" and a JSONObject "database"
The JSONObject "database" in this file usually should contain such objects, like "entities", "views", "setupQueries", ets.
