Android Studio Quiz

When working with Android development, images are typically stored in the "Drawable" folder. This folder is specifically designed for storing image assets that will be used in the user interface of the application. Therefore, when copying and pasting an image, it should be placed in the "Drawable" folder to ensure that it can be easily accessed and utilized within the app.

The correct answer is MainActivity.java. This file is where most of the app coding is done in Android Studio. It contains the main code for the app's functionality and is responsible for controlling the app's behavior and user interface. The MainActivity.java file is an essential part of the Android app development process and is where developers write the code to define the app's behavior and logic.

The correct answer is "android:src="@drawable/trainstation"". This is the correct way to reference an image with the name "trainstation" in an Android application. The "@drawable/" prefix is used to indicate that the image is located in the drawable resource folder, and "trainstation" is the name of the image file without the file extension. By using this syntax, the image will be properly displayed in the designated location.

Pressing this icon in Android Studio opens the AVD Device Manager. The AVD Device Manager is a tool used to manage and create virtual devices for testing Android applications. By opening this manager, developers can create, edit, and delete virtual devices, as well as launch them for testing purposes. This feature is essential for developers to ensure that their applications are compatible with different device configurations and screen sizes.

The correct line of code to get the ID of the EditText is "EditText TextHandler = (EditText)findViewById(R.id.nameTextField);" This line of code uses the "findViewById" method to locate the EditText with the ID "nameTextField" and assigns it to the variable "TextHandler" of type EditText.

The correct answer is activity_main_xml because this file is responsible for defining the layout of the main activity in an Android application. It contains the XML code that specifies the elements and their properties, including the ImageView that displays the image.
