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

We have a custom view that extends android.widget.ProgressBar. Our progress bar is not touchable, focusable, etc.: it just shows progress. Style for our custom progress bar extends
"Widget.AppCompat.ProgressBar.Horizontal". An item, named "progressDrawable", in our style, is a xml file . What we usually can see as a main single element in this xml file:

• A. A State List (<selector> element )
• B. An <ImageView> element with android:id="@+id/progress" identifier
• C. A Layer List (<layer-list> element) with items android:id="@+id/progress" and android:id="@+id/ background" inside it.

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. Never place this item in the app bar. Instead, list the item in the app bar's overflow menu.
• B. The action view associated with this action item (as declared by android:actionLayout or android:actionViewClass) is collapsible.
• C. 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.
• 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. 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.

Each time your test invokes onView(), Espresso waits to perform the corresponding UI action or assertion until the following synchronization conditions are met: (Choose three.)

• A. The message queue is not empty.
• B. The message queue is empty.
• C. All developer-defined idling res
• D. There are some instances of AsyncTask currently executing a task.
• E. Some developer-defined idling resources are not idle.
• F. There are no instances of AsyncTask currently executing a task.

Select 3 major components of the Room. (Choose three.)

• A. @RawQuery
• B. @Query
• C. @WorkerThread
• D. @Entity
• E. @Database
• F. @DAO
