Android :: User Preferences File Vs App Preferences File

Jun 23, 2010

My android application has two kinds of preferences:

1) I have user preferences defined in res/xml/preferences.xml so that users can manage their preferences with a PreferenceActivity.

2) I'd like to define another file for global configuration preferences of my app.

What is the best way to manage my app config preferences? Should I create another XML file with config values or should I specify those config values in strings.xml? What is the best practice for managing config preferences?

Android :: Preferences - How To Load The Default Values When User Hasnt Used Preferences-screen

Apr 22, 2010

I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.

I have set all the android:defaultValue="" for them.

When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:

CODE:.................

However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.

I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?

Android :: How To Delete A Named Preferences File In Droid?

Nov 5, 2010

I can create a new preferences file by calling Context.getSharedPreferences(String name, int mode), putting some values in the returned preferences' editor, and committing. However, I don't see an interface in the API to remove the created file when I no longer need it. I've tried Context.deleteFile(String name), passing in the same name argument from above, but that returns false, indicating the file wasn't actually deleted. I'm using MODE_PRIVATE, if that makes a difference. Browsing the source for context's implementation of the editor doesn't reveal any clues either, as far as I can tell. Any ideas? The background here is that I'm allowing my users to save copies of their "current" preferences so that they can restore previously saved settings. When they don't want those settings anymore, I want to remove the saved preferences file so it doesn't take up space. At the moment the best I can do is an edit().clear().commit on the file, which I believe will remove most of the contents. Not as good as delete, though.

Android : Save Preferences Other Than Shared Preferences?

Mar 19, 2010

My application is used on multiple platforms so it saves it preferences to a file (rather than to the standard Android SharedPreferences).

Is there any easy of reusing the PreferenceActivity to save preferences to a file or is it a case of creating a whole new activity to do the job? If the latter is the case is there a layout I can use that will make the activity look like the normal preferences screen? PreferenceActivity uses com.android.internal.R.layout.preference_list_content but this doesn't appear to be available to apps for reuse.

Android :: Can I Launch Different Activities On Startup Depending On User Preferences

Nov 2, 2010

I have a ListActivity and a MapActivity. I would like to launch either one of these activities on application startup that has been chosen by the user in a preferences window.

So far the only way I see to launch an activity on application startup is to specify it in the application manifest file using...code...

I am thinking I might have to start an activity that does nothing but looks at the user preferences and then launches either the ListActivity or MapActivity. Seems like a waste to have an activity do nothing but launch another activity. In my research I have not found any solution to this problem.

Android :: How To Implement Exclusive Preferences?

Jul 9, 2009

I would like to give users a choice of starting one of three different activities by choosing from three mutually choices. And I would like to provide users these choices as Preferences. If I use CheckboxPreference, user can select more than choices. Something like "RadioGroupPreference" would be good but it is not available from SDK. Can mutually exclusive preferences be implemented? Pointers or suggestions are greater appreciated.

Android :: Preferences Not Saved When Resume App

Jan 22, 2009

I'm having this problem with one of my apps where some people are reporting that their preferences are not being saved when they close and resume the app. The preferences theyre talking about happen to be actual Preferences (i.e. the built-in preferences manager for an activity). They say they're not doing anything special, just exiting the app and going back to it. Does anyone know why the prefs wouldn't be saved for only this select few people? I'm at a complete loss.

Is there a way to launch a dialog (say, the dialog I show to users the first time they launch the app) from a preferences entry? I don't see any examples doing this in the API Demos, nor have I seen it out in the wild. I do see a class called DialogPreference, but this doesn't seem to be what I want.

Android :: Getting Preferences In AppWidget Provider

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).
