Free AND-801: Android Application Development v8 Exam Questions and Answers
Android Application Development v8 is exam AND-801, part of Android ATC's certification programme. Android ATC is a private training company in Ontario, and its own about page states plainly that it is independent and not affiliated with Google — worth knowing, because the credential names invite the opposite assumption. It writes its own AND- codes, its own syllabus and its own exams, and names no independent accreditation anywhere on its site. The exams themselves are uniform: 45 questions in 90 minutes, 70% to pass, $150, online proctored. They do not expire, but each is tied to the Android version it was written against, which dates them in practice.
If you searched for AND-801 dumps, an AND-801 ExamTopics discussion or a free AND-801 PDF, this is the Android Application Development v8 question bank: practice questions with verified answers and explanations, a timed AND-801 practice test and updates whenever AndroidATC changes the exam.

Question #1
A developer has a GoogleMap object named map and a LatLng variable named nairobi. The app must center the map on nairobi and set the zoom level to 12 in a single camera update. Which statement should the developer use?
Correct answer: D
Explanation
CameraUpdateFactory.newLatLngZoom() takes a LatLng and a zoom level, so it centers the camera and sets the zoom in one update. newLatLng() changes only the center and zoomTo() changes only the zoom. addMarker() places a marker and does not move the camera, and zIndex only controls drawing order.

Question #3
A login screen contains an EditText for a numeric PIN. The field must show a numeric keypad and mask the characters the user types. Which attribute should the developer add to the EditText?
Correct answer: D
Explanation
The numberPassword input type restricts entry to digits with a numeric keypad and masks the typed characters. The number type shows digits but does not mask them. textPassword masks input but shows the full text keyboard, and phone is meant for telephone numbers and is not masked.

Question #4
Which unit should be used to define the text size of a TextView so that the text scales with the font size the user chooses in the device settings?
Correct answer: D
Explanation
sp (scale-independent pixels) works like dp but is also scaled by the user's font size preference, so it is the unit for text. dp ignores the font setting, px is a physical pixel that varies with screen density, and pt is a fixed typographic point.

Question #5
Which keyword declares a local variable in Kotlin whose value cannot be reassigned after it is initialized?
Correct answer: C
Explanation
val declares a read-only reference that can be assigned only once. var declares a variable that can be reassigned. let is a scope function and not a declaration keyword, and final is not used for local variables in Kotlin.

Question #6
In Kotlin, which modifier must a subclass use when it provides its own implementation of a member that its superclass declared as open?
Correct answer: A
Explanation
The override modifier is required in the subclass to replace an inherited open member. open is used in the superclass to allow overriding, which is why it is a tempting choice. overload is not a Kotlin modifier, and virtual does not exist in Kotlin.

Question #7
Which set of functions does the Kotlin compiler generate automatically for a class declared with the data modifier?
Correct answer: A
Explanation
A data class gets equals(), hashCode(), toString(), copy() and componentN() functions based on the properties in its primary constructor. clone(), compareTo() and finalize() are not generated automatically.

Question #8
Consider the following Kotlin code. open class Vehicle { open fun describe(): String = "Vehicle" } class Car : Vehicle() { override fun describe(): String = super.describe() + " Car" } fun main() { val v: Vehicle = Car() println(v.describe()) } What is the output?
Correct answer: D
Explanation
The object is a Car, so the overridden describe() runs even though the variable type is Vehicle. That method first calls super.describe(), which returns "Vehicle", and then appends " Car". The declared type only limits which members can be called, not which implementation executes.

Question #9
Which file in an Android Studio project declares the activities of the app and the permissions that the app requests?
Correct answer: A
Explanation
AndroidManifest.xml describes the app's components, such as activities and services, and its permission requests to the Android system. build.gradle holds build configuration and dependencies, strings.xml holds text resources, and proguard-rules.pro holds code shrinking rules.

Question #10
An activity has been stopped because the user navigated to another app. The user now returns to it and the same activity instance is brought back. Which lifecycle callback is invoked immediately before onStart() in this case?
Correct answer: B
Explanation
When a stopped activity comes back to the foreground, the system calls onRestart(), then onStart(), then onResume(). onCreate() runs only when the instance is first created, and onPause() runs when the activity is leaving the foreground.
