Android : Save Preferences Other Than Shared Preferences?

Mar 19, 2010

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.

Android :: Preferences - How To Load The Default Values When User Hasnt Used Preferences-screen

Apr 22, 2010

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?

Android :: Use Shared Preferences Between Activities?

Oct 29, 2010

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?

Android :: Export / Import Shared Preferences

Mar 25, 2010

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.

Android :: Accessing Shared Preferences From Different Activity

Oct 19, 2010

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?

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?

Android :: Accessing Shared Preferences Through Static Methods

Sep 27, 2010

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?

Android :: Accessing Shared Preferences In Services And Non Activities

Sep 23, 2009

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.

Android :: Get Shared Preferences / Static Reference To A Context Object

Oct 19, 2010

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.

Android :: User Preferences File Vs App Preferences File

Jun 23, 2010

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?

Android :: Get Shared Preferences From A Preference Activity In Android?

Apr 10, 2010

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.

Android :: Shared User ID And Signing

Nov 5, 2010

I am trying to have 2 applications which can access each other's data.I have a two test applications which I am experimenting with.I set the 'Shared user id' for each to 'com.gabysoft.sharedfiles'.However, when I sign the first app and try and install it, I get the error:

11-05 16:50:33.422: ERROR/PackageManager(61): Package com.gabysoft.sharedfiles1 has no signatures that match those in shared user com.gabysoft.sharedfiles; ignoring!

Clearly, I am not signing it correctly (I am using Eclipse's "Export signed application package" function).How do I properly sign the .apk file so that I don't have this problem?

Android :: Can I Launch Different Activities On Startup Depending On User Preferences

Nov 2, 2010

I 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.

General :: Google Play Services - Incompatible With Other Application Using Same Shared User ID

I have the famous problem with the shared user id. Whenever I try to install it, it says "Incompatible with other application(s) using the same shared user ID". I have tried putting it directly to /system/app, and I also have followed this guide [URL] ....., but with no result. It seems to rebuild this file in the reboot, so it's useless. I have a chinese phone without CWM recovery, so I can't flash anything, but I do have root. How to install Google play services in any way!

Android :: Which Data Will Be Deleted If User Uninstalls Application

Mar 18, 2010

If a user uninstalls an app from his phone, which data is explicitly deleted? I know that preferences are deleted. What about files on the sd card and about databases created by this app? If the data on the sd card is not deleted how can I avoid cluttering the users phone if I write larger amounts of data, like images on the sd card?

Android : Can I Share Preferences Between Apps?

Oct 26, 2009

I have a need to share preferences between two apps, where one app writes the preferences and the other needs read only access.

I notice that there is this API available in Context :

public abstract SharedPreferences getSharedPreferences (String name, int mode). Where I can set the mode to : MODE_WORLD_READABLE which according to docs means that it will allow all other applications to have read access to the created file.

My question is : What should be my filename so that the file gets created and is shared between the apps.

If I give a relative path (getSahredPrefs("filename", MODE_WORLD_READABLE)) then it gets created in the "data" directory of the writing app and the other non creating application is not able to get to it using the same arguments i.e. - getSahredPrefs("filename", MODE_WORLD_READABLE).

So I assume I need to provide a absolute path - something like ("/data/ data/<pkgname>/<subdir>/filename", MODE_WORLD_READABLE) but I do not know how to construct that generically using provided APIs so that it works on every Android phone/image.

Sony Ericsson Xperia X10 :: Messages Automatically Deleted Including Message Updates In Splines

Jun 21, 2010

i had to turn off the settings for the Mobile Networks MMS and data because it automatically connects to my provider and I am being charged and this usually happens when I touch on Timescape. I just dont know if its connected though but after doing so, after sometime my Messaging system prompts me up a message saying that there was an error (android.system.mms) and it needs to fore close and then after that all of my messages were automatically deleted including the message updates in the splines. I already went to the Service Center and the only thing they told me was it will be okay once I have updated to the new version which is the 2.1.
