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.)

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

Select correct demonstration of WorkRequest cancellation.

• A. workManager.enqueue(OneTimeWorkRequest.Builder(FooWorker::class.java).build())
• B. val request: WorkRequest = OneTimeWorkRequest.Builder (FooWorker::class.java).build() workManager.enqueue(request) workManager.cancelWork(request)
• C. val request: WorkRequest = OneTimeWorkRequest.Builder (FooWorker::class.java).build() workManager.enqueue(request) workManager.cancelWorkById(request.id)
• D. val request: WorkRequest = OneTimeWorkRequest.Builder (FooWorker::class.java).build() workManager.enqueue(request) val status = workManager.getWorkInfoByIdLiveData(request.id) status.observe(...)
• E. val request1: WorkRequest = OneTimeWorkRequest.Builder (FooWorker::class.java).build() val request2: WorkRequest = OneTimeWorkRequest.Builder (BarWorker::class.java).build() val request3: WorkRequest = OneTimeWorkRequest.Builder (BazWorker::class.java).build() workManager.beginWith(request1, request2).then(request3).enqueue()

Assume that an app includes a default set of graphics and two other sets of graphics, each optimized for a different device setup:
res/drawable/
Contains default graphics. res/drawable-small-land-stylus/
Contains graphics optimized for use with a device that expects input from a stylus and has a QVGA low- density screen in landscape orientation.
res/drawable-ja/
Contains graphics optimized for use with Japanese.
What happens if the app runs on a device that is configured to use Japanese and, at the same time, the device happens to be one that expects input from a stylus and has a QVGA low-density screen in landscape orientation?

• A. Android loads graphics from res/drawable-ja/
• B. Android loads graphics from res/drawable/
• C. Android loads graphics from res/drawable-small-land-stylus/

When your code execution reaches the breakpoint, Android Studio pauses execution of your app. You can

• A. advance to the next line outside the current method
• B. advance to the next line in the code (without entering a method)
• C. evaluate an expression at the current execution point
• D. examine the object tree for a variable; expand it in the Variables view. If the Variables view is not visible
• E. advance to the first line inside a method call
• F. continue running the app normally

If you are working with a Builder that creates a PeriodicWorkRequest to run periodically once within the flex period of every interval period. What statement is correct?

• A. The repeat interval must be greater than or equal to PeriodicWorkRequest.MIN_PERIODIC_INTERVAL_MILLIS and the flex interval must be greater than or equal to PeriodicWorkRequest.MIN_PERIODIC_FLEX_MILLIS.
• B. The repeat interval must be lower than or equal to PeriodicWorkRequest.MIN_PERIODIC_INTERVAL_MILLIS and the flex interval must be lower than or equal to PeriodicWorkRequest.MIN_PERIODIC_FLEX_MILLIS.
• C. The repeat interval must be greater than or equal to PeriodicWorkRequest.MIN_PERIODIC_INTERVAL_MILLIS and the flex interval can be anything in relation to PeriodicWorkRequest.MIN_PERIODIC_FLEX_MILLIS.
• D. The repeat interval must be greater than PeriodicWorkRequest.MIN_PERIODIC_INTERVAL_MILLIS and the flex interval must be greater than PeriodicWorkRequest.MIN_PERIODIC_FLEX_MILLIS.
