I want to save all the contacts into shared preferences.Is it possible?
I mean is there any upper size limit of shared preferences??How much data it can save?

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 RelatedI 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 would like to know why the size of my shared library .so is bigger than my .apk file generated with Eclipse? Approximatly the so size is twice the apk one. What is strange is after having installed it in the device (2.1 firmware) I checked the size of the apk when I uninstalled it from the device and surprisingly the apk size indicated is bigger even than the .so one. Is there any explaination of that?
View 2 Replies View RelatedIn 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 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.

I am using a ScrollView as a child of an AbsoluteLayout to display a list of items inside this AbsoluteLayout. Because the ScrollView is embedded in the AbsoluteLayout's design, I want to restrict it's size to fit the assigned area. Is there any way to set the height of the ScrollView or of the RelativeLayout that is the child of my ScrollView? My layout.xml (with just the important tags):
<AbsoluteLayout android:layout_width="fill_parent" android:layout_height="fill_parent" /> <...some TextViews...>
<ScrollView android:layout_width="wrap_content" android:layout_height="wrap_content"> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content"> <...some TextViews that I want to be able to scroll, all with wrap_content...> </RelativeLayout> </ScrollView>
<...again, some TextViews in the main layout...> </AbsoluteLayout>

Some of my customers are getting SQLiteFullException
The docs say that this means the SQLite database is full http://developer.android.com/reference/android/database/sqlite/SQLite... An exception that indicates that the SQLite database is full.
The exception text also opens the door for disk being full android.database.sqlite.SQLiteFullException: database or disk is full:
Question: Is there a limit to amount of space that a application or sqlite db can use on the internal disk ?
That there wasn't a limit to the size of an application that could be downloaded over the air (OTA) but I wonder if a limit, like that imposed by the Apple App Store (20MB) exists now that the Nexus one is running on AT&T's 3G network as of today.

View 6 Replies View RelatedI am trying to load an XML file from res/raw folder in my Android project when the app first runs. I do this with this line:
InputStream xmlStream = getResources().openRawResource(R.raw.xmlfile);
I then want to use a SAX Parser to get data from the XML file. When doing this LogCat shows the following error:
Data exceeds UNCOMPRESS_DATA_MAX (1290892 vs 1048576)
Is there anyway around this 1MB limit?
After a few Google searches, I found people who have split their files into 1MB chunks, but these weren't XML files so I am not sure how I would rejoin them before making the InputSource for my SAX Parser.
My file is not created by me, so I can't really edit it (although I may have to) and my code works if I retrieve it from Internet. Its around 1,300KB in size, so I want to not have to download it each time app run
I know the limit for mms/pic is 5mb (5000kb) but I was looking for the hack for android to fix this on the evo. I'm sure an arcsoft file cab wont fix it and i haven't seen a regedit app to go and change settings. Is there any way I can set my evo to max sprint value?
View 2 Replies View RelatedI have a 4GB video file in MP4 format. I can view the file perfectly on my laptop using the defaul media player "Media Player Classic". I have transferred the file to my new EVO and I cannot watch the video...it does not even load. I get the following error message "Cannot Play Video" and "Sorry, this video cannot be played." I have tried the default video player, doubletwist and Meridian with no success. I then thought perhaps the single 4GB file is too large for the EVO and Android apps. I am about to break the file into smaller chunk, but I wanted to ask the forum first.
