View 1 Replies View RelatedAndroid : Regarding Storing Of Data From User In Database
Aug 19, 2010I am working on some sample programs, where i have to take the value from the user and store it in the database. I have used DroidDraw to create the XML code for UI.For now, I have just started with a textbox. So, I have to take the value from this textbox and store it in a database. I am using SQlite browser to create tables. I read in some forums, that one way of doing this.
1. Copy the db file in the asset folder of the android project and use the AssetManager class. But i am not able to figure out how to use the asset manager class here. Or if I could get some simpler suggestions on how to store the value from user into the database, it would be great.
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 :: 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 3 Replies View RelatedAndroid :: 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.

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 :: 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?

View 5 Replies View RelatedAndroid :: 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 :: 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.

Android :: User Preferences File Vs App Preferences File
Jun 23, 2010My android application has two kinds of preferences:

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

Android :: Storing A User Selection That Stores Itself For Use On Reload In App
Aug 2, 2010I've built a dialog that asks the user to pick a city from the list provided when the application first opens. The dialog works perfectly, however I want to store the user's choice so that when the app is opened a second time, it checks to see if the user has already made a selection previously. If they have, it doesn't display the dialog and defines the city variable as their previously chosen preference. And obviously, if they haven't made a selection previously (because its their first time opening the app or for some reason the app couldn't read the stored preference), it displays the dialog.

View 5 Replies View RelatedAndroid :: Can I Launch Different Activities On Startup Depending On User Preferences
Nov 2, 2010I 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.
