/** |

* Abstract activity that helps implement a preference screen for key-bound settings, i.e. settings of which there can |
||||||
|
* be multiple and which are identified by an ascending order number/unique key. A typical implementation calls |
||||||
|
* {@link #init(int, int)} during the {@link #onCreate(android.os.Bundle)} (but after calling super.onCreate(Bundle)) |
||||||
|
* and then call initXPreference for each contained preference. {@link #onPreferencesChanged()} can be overridden to |
||||||
|
* react to preference changes, e.g. when field availability should be updated (and where preference dependency isn't |
||||||
|
* enough). |
