For example, our preferences.xml file was added by addPreferencesFromResource (R.xml.preferences). Our preferences.xml file contains such item:
<ListPreference android:id="@+id/order_by" android:key="@string/pref_sort_key" android:title="@string/pref_sort_title" android:summary="@string/pref_sort_summary" android:dialogTitle="@string/pref_sort_dialog_title" android:entries="@array/sort_oder" android:entryValues="@array/sort_oder_value" android:defaultValue="@string/pref_default_sort_value" app:iconSpaceReserved="false" /> In our Fragment, we can dynamically get current notification preference value in this way:
- A. val sortBy = PreferenceManager.getSharedPreferences(context).getBoolean( context!!.resources.getBoolean(R.bool.pref_default_sort_value), context!!.getString(R.string.pref_sort_key) )
- B. val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(R.string.pref_sort_key), context!!.getString(R.string.pref_default_sort_value) )

NEW QUESTION 80
When scheduling unique work, you must tell WorkManager what action to take when there is a conflict. You do this by passing an enum when enquing the work. For one-time work, you provide an ExistingWorkPolicy, which supports some options for handling the conflict. (Choose four.)
- A. APPEND_OR_REPLACE (functions similarly to APPEND, except that it is not dependent on prerequisite work status. If the existing work is CANCELLED or FAILED, the new work still runs)
- B. KEEP (existing work and ignore the new work)
- C. APPEND (the new work to the end of the existing work. This policy will cause your new work to be chained to the existing work, running after the existing work finishes)
- D. APPEND_OR_KEEP (functions similarly to APPEND, except that it is not dependent on prerequisite work status. If the existing work is CANCELLED or FAILED, the new work still not runs)
- E. REPLACE (existing work with the new work. This option cancels the existing work)
- F. DESTROY (if any work exists, the new work will be ignored)
- G. APPEND_OR_DESTROY (if no any work exists, the new work will be ignored)
- H. APPEND_AND_RUN (functions similarly to APPEND, except that it is not dependent on prerequisite work status. If the existing work is PAUSED, the new work still runs)

What statements about InputStreamReader (java.io.InputStreamReader) are correct? (Choose two.)
- A. Each invocation of one of an InputStreamReader's read() methods may cause one or more bytes to be read from the underlying byte-input stream. To enable the efficient conversion of bytes to characters, more bytes may be read ahead from the underlying stream than are necessary to satisfy the current read operation.
- B. An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.
- C. An InputStreamReader is a bridge from character streams to byte streams: It reads characters using a specified charset and encodes them into bytes. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.
- D. No any invocation of one of an InputStreamReader's read() methods can cause some bytes to be read from the underlying byte-input stream.
