Android :: Shared Preferences Not Accessible In Service / Fix It?
Mar 3, 2009
We are using SharedPreferences(Not default preferences.) to store our application related settings. These settings are not accessible in the background service as the application context is different from service context. It always returns the default values. We want to have our own UI to manage settings. So, we don't want to use PreferenceActivity.
Is there a way or hack to access SharedPreferences from inside a service which are created by application?

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.

Does Android provide smth. like that OR do I have to check every time during start of my app "Oh, am I freshly installed? Do I have to initialize the Shared Preferences now?"

I have a user preference in my app, which gets ued by different activity. I would like to know the best way to utilize those preferences between different activities in my App.
I have this idea to create a shared preference object from the main activity and from there send intents to the different activities to take actions. would it work?.. or just keep calling getsharedpreferences() from every activity?

I would need to export the shared preferences and load it on another device. Is this possible in a direct way somehow? (without exporting the keys one by one and writing to a custom file) Another question is that there is any XML parser which has the same functionality like SharedPreferences (getstring/addstring, getint/ addaddint etc.) and saves/loads the result to a path anywhere? (sdcard for example) I know SharedPreferences uses some xml's in the background but that xml is not readable as a file without admin rights as far as I know so it's not quite suitable for what I need.

When you establish a shared preference such as below.
public static final String PREFS_HI = "MyPrefsFile";
Can you access it from other activities just like you would normally do?
SharedPreferences settings = getSharedPreferences(PREFS_HI, 0);
Or is there something unique that you must do to access the preferences?

Is it possible to have multiple Shared Preferences per app? If you create a PreferenceActivity, the values by default are persisted to /data/data/[PACKAGE_NAME]/shared_prefs/[PACKAGE_NAME]_
preferences.xml
Is there a way to have multiple such files and which one to use for a given PreferenceActivity?

I have some information stored as SharedPreferences. I need to access that information from outsite an Activity (in from a domain model class). So I created a static method in an Activity which I only use to get the shared preferences. This is giving me some problems, since apparently it is not possible to call the method "getSharedPreferences" from a static method. Here's the message eclipse is giving me:
Cannot make a static reference to the non-static method
getSharedPreferences(String, int) from the type ContextWrapper
I tried to work around this by using an Activity instance, like this:
public static SharedPreferences getSharedPreferences () {
Activity act = new Activity();
return act.getSharedPreferences("FILE", 0);
}
This code gives a null point exception. Is there a work-around? Am I going into an android-code-smell by trying to do this?

I have some shared preferences (user_id, email) that I want to access from services and classes that are not subclassed from Activity. I have been trying to implement this today and keep hitting roadblocks. In particular, when I try to access getSharedPreferences, I get a null pointer exception. My code is posted below. My goal here is to allow read access the shared preferences to objects and (potentially) services that aren't going to be directly exposed to the user.
<snip> public class MyPrefs extends Service {
public static final String PREFS_NAME = "MyPrefs";
private int user_id;
private String user_email;
private String user_password;
private Editor editor = null;
private SharedPreferences settings = null;
public MyPrefs () {
settings = this.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
}
</snip>
this.getSharedPreferences line causes a null pointer exception.

In my Android application, I have to call the getSharedPreferences in non-activity classes. In order to avoid passing a Context object to each constructor of these classes (and because many of them are classes with only static methods which don't have a constructor), I have implemented these steps : The main activity of my application (which is launched at startup) is called Dispatcher. In the onCreate method of this class, I keep a reference to the created Dispatcher object in a static public variable of the Dispatcher class which can be accessed from any class in the project.

I am using a PreferenceActivity to show some settings for my application.I am inflating the settings via a xml file so that my onCreate (and complete class methods).These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity.

I have a app that only consists of 2 services and a broadcast receiver (they check the internet periodically). I need to store preferences that can be shared across those services. Is this the same as for an activity? Just use getsharedpreferences()? This doesn't seem to be documented very well.

I have a Service and a PreferenceActivity that allows the user to edit some preferences. I would like to restart the Service once the user is done with the PreferenceActivity.
I understand that I can register onChange listeners for individual preference changes, but I do not want to restart the Service as each preference changes. I would like to do this when the user is done editing all the preferences. Short of having a "Apply Now" button in the PreferenceActivity, I do not see a straightforward way of doing this.

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?

My app is downloading a file that does not need to be kept. So I was trying to put it in the directory returned by Environment.getDownloadCacheDirectory() (that returns "/cache").
But apparently it is not accessible, (a FileNotFoundException is thrown).

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?

I think this is a great idea for thread discussion, alot of people are worrying about the isolated/limited connection to Sprint's 4G, I think its a little overblown, the Evo will still be an awesome phone. What are some things on the Evo only accessible by 4G and not 3G?
For example, I've noticed the general knowledge of consumers didnt know youre still able to use Qik by both front and rear cameras via 3G, granted I dont know if the quality is better if used by 4G, however its still useable, if youve been watching the sticky thread above about general information on the Evo, there has been some Qik links where a Sprint or other marketing employee has been recording videos via the front facing 1.3 camera, in Kansas City, where they dont have 4G yet. Not only that but Qik is also available in the Android Market for other phones. --->Android Market
Qik, and Video Sharing? hell yes. Video Chatting through 3G? Possibly not.
I've also noticed in some Evo videos a Sprint employee states that the option to watch HQ Youtube videos only occurs in 4G, but I'm still curious as to what the quality is on 3G. I've also read that you can watch Hulu via the Skyfire browser, which to me is HUGE plus, unfortunately, Skyfire isnt available on Android just yet.

When in the messaging app, and in text message conversations I am having many issues. 1st issue: conversations or "threads" as it is put are seperated, which I like this option, but it also makes it an issue. I am unable to forward any messages I receive.
attachments in messages are not accessable, or able to be saved. I can not save photos, video, music, files ect. I can not set any attachments as ringtones, screen savers, backgrounds. And I can not forward any of the information that is included in a text. I have become very frustrated with the Droid, I thought this was a great phone but seems for the pricetag and hype, I am unable to do less with it as simple functions that I had on my previous phone the LG Chocolate. I can not save anything I receive, and I also can not send any of my music files or recordings as an attachment.
I may not have this whole Droid thing figured out, but I dont want it to take me a month to figure it out. And it seems like I am going past my "Worry Free" period of time. I was unable to save many of my items from old phone to Droid, and that was a bother. But the text messaging is my biggest complaint, I liked the ability to save sounds, forwards sounds photos ect. And I can not do this now with the Droid, is there a way to fix this issue?

I'm developing an Android and web application that will function as a service (use the same data). My question is how should the data be stored to allow for both the web and the android application to have access to the same set of data? Should the android application connect to the sites MySQL server to store/access data? If so how do I allow someone to access the data when they are not in a service area?

I have multiple applications which use the same ContentProvider code for internal WebView to access local files (application private). Because the ContentProvider has the same code base (package name, content uri), this will cause problem when deployed 2 or more of my application in the same device? How do I make the contentProvider only accessible by its application and prefer a solution without code changes.
