Filter logcat messages. If in the filter menu, a filter option “Show only selected application”? means:
For example, we have a file in our raw folder app/src/main/res/raw/sample_teas.json. To get an
InputStream for reading it, from out Context context, we can do this:
In a class PreferenceFragmentCompat. What method is called during onCreate(Bundle) to supply the preferences for this fragment. And where subclasses are expected to call setPreferenceScreen (PreferenceScreen) either directly or via helper methods such as addPreferencesFromResource (int)?
LiveData.postValue() and LiveData.setValue() methods have some differences. So if you have a following code executed in the main thread:
liveData.postValue("a"); liveData.setValue("b");
What will be the correct statement?
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 Out 
you can
What do you want from Room when you create a DAO method and annotate it with @Delete?
Example:
@Dao

fun deleteUsers(vararg users: User)
}
About running a debuggable build variant. Usually, you can just select the default "debug" variant that's included in every Android Studio project (even though it's not visible in the build.gradle file). But if you define new build types that should be debuggable, you must add ‘debuggable true’ to the build type. Is that mostly true?
For example, our preferences.xml file was added by addPreferencesFromResource (R.xml.preferences). Our preferences.xml file contains such item:
android:title="@string/pref_notification_title" android:summary="@string/pref_notification_summary" android:defaultValue="@bool/pref_notification_default_value" app:iconSpaceReserved="false"/> In our Fragment, we can dynamically get current notification preference value in this way:
