Trying to create shared preferences for my class representing my api and one for my main class. I create a shared preference file by making this call in my api & main classes String PREF_NAME = "API"; this.pref = context.getSharedPreferences( PREF_NAME, Context.MODE_PRIVATE );
the log gives me this....................

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.
I want to know how we can use shared pref in different application.

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 want to save a string with SharedPreferences class. The string is quit long. I really want to know the maximum length of a string that can be save in shared preferences in android.

View 3 Replies View RelatedI 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 RelatedWhen 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?
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?
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]_

Is there a way to have multiple such files and which one to use for a given PreferenceActivity?
Shared Preferences are as such used to keep the data static and available.Is there a chance that i can use this ahred preference values over a content uri and make accessible to all ?
View 5 Replies View RelatedMy 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 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 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.

View 3 Replies View RelatedI 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?

How can I create a XML file that has identation or, at least, line breaks between each tag? I'm using class XMLSerializer (available in Android) to handle the XML creation.
XMLSerializer serializer = new XMLSerializer();
StringWriter writer = new StringWriter();
serializer.setOutput(writer);
String xmlFileContents = writer.toString();
Then I use the contents of xmlFileContents to create a file, using a BufferedWriter. The file is written, but the XML is not idented, and would like it to be.
