I looked into some examples of sharing data to other apps using content Provider. All these examples talks about sharing sqlite dbs. I need to share data under shared Preferences of my app to other apps using content Provider. Can I use content Provider to do that ?. Please let me know some pointers or sample code to share data other than sqlite db using content provider.
View 3 Replies View RelatedI am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.
how can i create a custom content provider like contact content provider? i know how to create custom content providers but i want to integarte to device such a way that it canbe accessed by all application installed in that device.

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]_
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.
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).
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.

View 6 Replies View Relatedmy android application is handling a large database of bus passage time and we would like to allow others application to be able to display certains bus passage time. We would like to use a content provider to do that. Most example seems to be about using an SQL database, but we use some custom text file. I was wondering what would be the best way to do that. I was thinking I could use a Content Provider and implement the Cursor interface on a custom object that I would manually fill with my text data. Would this be possible ? Anyone have a better idea (excluding changing to SQL lite of course)?
View 1 Replies View RelatedI 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.
