• Question 96:

  An example. In our ViewModelFactory(that implements ViewModelProvider.Factory) we have an instance of our Repository, named mRepository. Our ViewModel has such constructor:

  class MyViewModel(private val mRepository: MyRepository) : ViewModel() ...

  Next, in our ViewModelFactory create ViewModel method (overriden) looks like this:

  override fun create(modelClass: Class): T { return try { //MISSED RETURN VALUE HERE” } catch (e: InstantiationException) { throw RuntimeException("Cannot create an instance of $modelClass", e) } catch (e: IllegalAccessException) { throw RuntimeException("Cannot create an instance of $modelClass", e) } catch (e: NoSuchMethodException) { throw RuntimeException("Cannot create an instance of $modelClass", e) } catch (e: InvocationTargetException) { throw RuntimeException("Cannot create an instance of $modelClass", e) } }

  B. modelClass.getConstructor(MyRepository::class.java).newInstance()

  B. String sortBy = PreferenceManager.getSharedPreferences(getContext()).getString(getContext().getString(R.string.pref_default_sort_value),getContext().getString(R.string.pref_sort_key));
  C. boolean sortBy = PreferenceManager.getSharedPreferences(getContext()).getBoolean(getContext().getResources().getBoolean(R.bool.pref_default_sort_value),getContext().getString(R.string.pref_sort_key));
  D. String sortBy = PreferenceManager.getDefaultSharedPreferences(getContext()).getString(getContext().getString(R.string.pref_sort_key),getContext().getString(R.string.pref_default_sort_value))

  E. attr.windowDrawsSystemBarBackgrounds and the status bar must not have been requested to be translucent with R.attr.windowTranslucentStatus. Corresponds to Window.setStatusBarColor(int).
  F. The color for the navigation bar. If the color is not opaque, consider setting View.SYSTEM_UI_FLAG_LAYOUT_STABLE and View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION. For this to take effect, the window must be drawing the system bar backgrounds with R.attr.windowDrawsSystemBarBackgrounds and the navigation bar must not have been requested to be translucent with
  G. attr.windowTranslucentNavigation. Corresponds to Window.setNavigationBarColor(int).
