Android :: Accessing Shared Preferences From Different Activity
Oct 19, 2010When 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?
Android :: Accessing Shared Preferences Through Static Methods
Sep 27, 2010I 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?
Android :: Accessing Shared Preferences In Services And Non Activities
Sep 23, 2009I 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.
Android : Save Preferences Other Than Shared Preferences?
Mar 19, 2010My 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 :: Export / Import Shared Preferences
Mar 25, 2010I 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.
View 4 Replies View RelatedAndroid :: Shared Preferences Not Accessible In Service / Fix It?
Mar 3, 2009We 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?
Android :: Possible To Have Multiple Distinct Shared Preferences Per App?

Android :: Get Shared Preferences / Static Reference To A Context Object
Oct 19, 2010In 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.

View 1 Replies View RelatedAndroid :: Preferences - How To Load The Default Values When User Hasnt Used Preferences-screen
Apr 22, 2010I 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?

View 4 Replies View RelatedAndroid :: Transfer Preferences From Demo To Paid Application
Nov 16, 2010This comes up because I am changing the model for my freed and paid apps. Besides all the other things I need to figure out to build this (I'm trying the library method), I'd like to transfer preferences smoothly from DEMO app to paid App. I'm sure that some of you are old hands at this and can give some advice. I've tried the Demo and License, where a license app will unlock the Demo app and make it full.
The Market users can't handle that. My customers didn't want to have two app icons once they installed the license. So I made it invisible. Now I have users that say they can't "open" the license after purchase. It states very clearly in the app description that they need to install the free version first, but I've discovered that not everyone reads that vast 325 character description before buying even some of the most expensive apps on the Market.
I've decided not to fight it. I do believe that customers will be more happy overall and there will be less refunds, if they do try the demo app first. It gives them 16 days to try instead of 24 hours to get a refund. But I'm not going to force that. So, I'll be going down the Demo and Full model route. Just as an aside, I really wish the market would support time limited trials. There is difference between real support and faking it as I have been.

Android :: DWR And Accessing Application From Browser
Aug 13, 2009I am experiencing a problem with accessing an application from the Android-browser. The application uses DWR to persist connections to the clients that are connected with it. Everything works fine for me, except that if the application does not send any data to the client on the Android-phone for 2 minutes, the connection seems to be lost and no data arrive at the client. The same scenario works just fine on Firefox, Opera and Chrome. If the pause between two data transfers is less than 2 minutes, it works just fine.
So, now my question: Is there some timeout setting for the android browser that I am missing? Or is this some built-in bug/feature/whatever that I cannot circumvent? I know that I could prevent this from happening with some sort of heartbeat, I would just like to why this is happening.
