Hey everyone,
i now had a problem with an OnSharedPreferenceChangeListener multiple times. The problem was: it just never got called. I had a PreferenceActivity to manage the settings and i wanted to get notified in my main Activity when something changed. But my listener never was called.
Recently i found the answer to that problem on StackOverflow. The thing is that the SharedPreference keeps its listeners in a WeakHashMap. Which leads to the inability to use a nested inner class a the listener since it will be garbage collected.
So the solution to that problem is just storing the listener in a private variable like this: [code language=“java“]private OnSharedPreferenceChangeListener prefListener;[/code]
And everything will work just fine 🙂
