By default, the notification's text content is truncated to fit one line. If you want your notification to be longer, for example, to create a larger text area, you can do it in this way:

• A. var builder = NotificationCompat.Builder(this, CHANNEL_ID)
  .setContentText("Much longer text that cannot fit one line...")
  .setTheme(android.R.style.Theme_LongText);
  ...
• B. var builder = NotificationCompat.Builder(this, CHANNEL_ID)
  .setContentText("Much longer text that cannot fit one line...")
  .setStyle(NotificationCompat.BigTextStyle()
  .bigText("Much longer text that cannot fit one line..."))
  ...
• C. var builder = NotificationCompat.Builder(this, CHANNEL_ID)
  .setContentText("Much longer text that cannot fit one line...")
  .setLongText("Much longer text that cannot fit one line..."))
  ...

The Layout Inspector in Android Studio allows you to compare your app layout with design mockups, display a magnified or 3D view of your app, and examine details of its layout at runtime. When this is especially useful?

• A. when your layout is built entirely in XML rather than runtime and the layout is behaving expectedly.
• B. when your layout is built at runtime rather than entirely in XML and the layout is behaving unexpectedly.

When your code execution reaches the breakpoint, Android Studio pauses execution of your app. You can then use the tools in the Debugger tab to identify the state of the app. With Step Over you can

• A. evaluate an expression at the current execution point
• B. advance to the next line outside the current method
• C. advance to the next line in the code (without entering a method)
• D. examine the object tree for a variable; expand it in the Variables view.
• E. continue running the app normally
• F. advance to the first line inside a method call

Working with Custom View. Once you define the custom attributes, you can use them in layout XML files just like built-in attributes. The only difference is that your custom attributes belong to a different namespace. Instead of belonging to the http://schemas.android.com/apk/res/android namespace, they belong to:

• A. http://schemas.android.com/[your package name]
• B. http://schemas.android.com/apk/[your package name]
• C. http://schemas.android.com/apk/res/[your package name]

Custom views and directional controller clicks. On most devices, clicking a view using a directional controller sends (to the view currently in focus) a KeyEvent with:

• A. KEYCODE_BUTTON_START
• B. KEYCODE_CALL
• C. KEYCODE_BUTTON_SELECT
• D. KEYCODE_DPAD_CENTER
