preferences

I'm working on an Eclipse plugin (or in fact, a plugin for an Eclipse-based application) which needs some configuration to be entered by the user. From looking at the documentation, there seem to be two preference APIs - one in org.eclipse.core.runtime.preferences , extending/implementing the OSGI prefererence API , another one, JFace specific, in org.eclipse.jface.preference . Then we have org.eclipse.ui.preferences , too. The OSGI API has a hierarchic Node tree - a preference node ( Preferences or IEclipsePreferences ) can have multiple subnodes, which themselves can contain both individual

I wonder if it is possible to get values of certain preferences set in about:config using javascript? Incentive is to get value of preferences set in firefox addon i've created when user lands on addon front end. Basically, I'm trying to identify users landing on FE without asking them to login explicitly. Yes, you can. First, you need to know that Mozilla uses the XPCOM interfaces for the preferences system. Three used interfaces are nsIPrefService , nsIPrefBranch and nsIPrefBranch2 . The preferences service is instantiated in the same way you instantiate any XPCOM service . Two examples to

I have an app on the Google Play market. For various reasons that I won't bother going into, I have changed the type of some of my preferences. For example a preference type was an Integer and in the most recent version it is now a String. I imagine this isn't good practice but unfortunately I had to do it. My concern is that when someone updates to the new version their app will crash as the preference types have changed. For this reason I would like to clear the preferences whenever the app is updated (again I realise not ideal!) Is this possible? Balázs Édes The SharedPreferences.Editor

I need to crypt my password before save it to local android database. Everything work fine without encryption, I have preferences.xml and so. How can I call a function after I change value of preference (for example, password) ? Here is my code: public class Preferences extends PreferenceActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); // Get the custom preference Preference customPref = (Preference) findPreference("pass"); customPref.setOnPreferenceChangeListener(new

I seem to be having trouble reading preferences from my AppWidgetProvider class. My code works in an Activity, but it does not in an AppWidgetProvider. Here is the code I am using to read back a boolean: SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); boolean autoreplyon = settings.getBoolean("autoreplyon", false); However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class). Thanks in advance for any suggestions! getSharedPreferences() , should you choose to use it, is only

I have a ListPreference which look something like this: <ListPreference android:title="Choose item" android:summary="..." android:key="itemList" android:defaultValue="item1" android:entries="@array/items" android:entryValues="@array/itemValues" /> Then, I have another preference which should only be enabled if "item3" is selected in the ListPreference . Can I somehow accomplish this with android:dependency ? Something like android:dependency="itemList:item3" Thanks! The only way you can do something like this is programmaticly. You'd have to set up an change listener on the ListPreference and
