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...")
  .setLongText("Much longer text that cannot fit one line..."))
  ...
• 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...")
  .setTheme(android.R.style.Theme_LongText);
  ...

The diagram below shows a basic form of the recommended architecture for apps that use Architecture Components. The architecture consists of a UI controller, a ViewModel that serves LiveData, a Repository, and a Room database. Drag modules to correct places.

Correct Answer:

In our TeaViewModel class, that extends ViewModel, we have such method:
public LiveData<Tea> getTea() { return mTea;
}
An observer in our Activity (type of mViewModel variable in example is TeaViewModel) is set in this way:
mViewModel.getTea().observe(this, this::displayTea);
What will be a correct displayTea method definition?

• A.private void displayTea(LiveData<T>)
• B.private void displayTea()
• C.private void displayTea(LiveData<Tea>)
• D.private void displayTea(Tea tea)

For example, suppose that in a XML file (res/menu/menu_main.xml as an example), where menu items are described, we have such item:
...
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="@string/menu_action_settings"
app:showAsAction="never" />
...
Attribute "app:showAsAction" shows when and how this item should appear as an action item in the app bar. What value "never" in this attribute means?

• A.Always place this item in the app bar. Avoid using this unless it's critical that the item always appear in the action bar. Setting multiple items to always appear as action items can result in them overlapping with other UI in the app bar.
• B.Also include the title text (defined by android:title) with the action item. You can include this value along with one of the others as a flag set, by separating them with a pipe.
• C.Never place this item in the app bar. Instead, list the item in the app bar's overflow menu.
• D.Only place this item in the app bar if there is room for it. If there is not room for all the items marked by this value, the items with the lowest orderInCategory values are displayed as actions, and the remaining items are displayed in the overflow menu.
• E.The action view associated with this action item (as declared by android:actionLayout or android:actionViewClass) is collapsible.

To build a debug APK, you can open a command line and navigate to the root of your project directory. To initiate a debug build, invoke the assembleDebug task:
gradlew assembleDebug
This creates an APK named [module_name]-debug.apk in [project_name]/[module_name]/build/outputs/apk/ Select correct statements about generated file. (Choose all that apply.)

• A.The file is already aligned with zipalign
• B.You can immediately install this file on a device.
• C.The file is already signed with the debug key
