Android :: SharedPreferences Bug When Writing Strings With Ampersands In Them
Mar 6, 2009
I've just tracked down a weird bug in our app where SharedPreferences were failing between power cycles of the phone.
It turns out that one of the strings we were saving had an "&" in it. When I look at the xml that is being persisted I see that this is being encoded as && instead of just &
This means that when you come to read the settings back you don't get any values at all. Is this a known issue? I see lots of posts about preferences dissappearing, but nothing about this.

Dear all, I'm making a simple file decoder for Android 2.2 that needs to find the filename of the encoded file from a header. This filename should then be used as the filename for the decoded file (as you would expect).The filename is identified by the substring name=, so the actual name starts 5 places after that. The line is read by a BufferedReader and temporarily stored in currLine.For some reason I can't understand nor find on the web, Strings do not always seem to be Strings.Gives no output file, nor an IO exception. The string is parsed properly though: from the System.out debugging lines.

I've got a map of about 500 entries. Strings are all very short (less than 5 chars).Its read-only data I want to read once at app-startup. What's the best way to store this so that loading this data is fast?I've tried storing the data in a CSV in res/raw but this takes about 700ms to parse on my N1, so I'm hoping there's a faster way.

Is it possible to reference other strings inside of strings.xml ?
Something of the form...
(If it did exist, there would of course be problems of circular, infinite definitions, etc. to beware of).

by which the resource "bar" becomes an alias for the resource named "foo".What I would for my app is a possibility to combine an existing resource prefix with different suffixes,where the resource "bar" would yield the string "foobar". Its clear that '+' doesn't work here but is there some other option to achieve such a string concatenation, so that one could define a bunch of string resources that have a common prefix?I realize of course that I could do such resource string concatenation at runtime but defining them statically in the resources would seem so much more elegant and simpler.

My problem is using SharedPreferences. I just created a <PreferenceScreen> which holds inside a <ListPreference> with an array of 5 different values. Very simple! The array of values are different numbers: 1, 2, 5, 10 and 30.Every time I change the setting, the application remembers that and I can see the setting I chose when I access the preferences once again (as an user). Now, in the code, when I retrieve the setting using the key (e.g. getString("delay", default_delay);), I always get the default value, it seems that the SharedPreferences does not find my setting. Can anybody help? I have read about SharedPreferences.getEditor().commit(), but that should be used only when changing settings from the code, not from the UI preferences.

Now that we can Examining sqlite3 Databases from a Remote Shell, is it possible to examine SharedPreferences from adb shell? Since it would be much more convenient to examine and manipulate SharedPreferences from command line when debugging. Or put in another way, in what files SharedPreferences are saved, and how to view and modify these files?

I am trying to save the date of file parsing, so that when next time user, opens the application, the date can be checked against the last parsing date. I am using shared preference to save the data and retrieve it, but getting error. here is the code:
SharedPreferences settings = getPreferences(0);
String today = new Date(System.currentTimeMillis()).toString();
SharedPreferences.Editor edit = settings.edit();
System.out.println("******** Today : " + today);
edit.putString("lastdate", today);
String fetch = settings.getString("lastdate", "0");
System.out.println("******** Fetch : " + fetch);
txtTest.setText(fetch);
but I am getting null pointer error. am I missing something?

I'm trying to prepare an update to one of my apps and I just realized that the updated version cannot read or write over the previous version's SharedPreferences.
Some details: * I'm using the 1.6 SDK and compiling for 1.5.3. * My androidmanifest.xml does not have a sharedUserId (I didn't think I need one if I was not sharing data between different apps).
How to reproduce: * Install my current app from the market * Run the app * Exit and save the setting - invoking SharedPreferences Editor commit (it's using MODE_PRIVATE) * Now install my new update (via a browser download) * Run the app * Everything works fine * Exit & Save *** Now reboot the phone * Run the app again ==> Can no longer access old data or write over it!!
Did I do something wrong? Is it because of the sharedUserId thing? Is it because of the way I'm testing - via market then browser? Why is LogCat reporting a UID change? ==> mismatched uid: 10031 on disk, 10046 in settings; Can I recover from this? I don't want to delete all of my users' data. error ...

I'm having a hard time figuring out the best way to pass simple values from onPause and onResume in the Android activity lifecycle. I understand how to use get and put extra bundles for activity to activity data, but does that work for passing data between the same activity? Should i used SharedPreferences?

From what I can incur out of the SharedPreferences documentation, I can update a preference, add one or clear all preference values in a shared preference file.
But I want to completely clear everything inside a shared preference file, not just the values, but the preferences they refer to as well.

Currently, I'm using the following code across all of my activities in my app to store application level variables and carry values between activities..
prefs = this.getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
I didn't have a PreferenceActivity prior to this, but now I do and I am looking to store a few user prefs from this new PreferenceActivity in the same sharedPreferences tag, "MyPrefs".
I know I can access the PreferenceActivity SharedPrefs from my activities via
prefs = PreferenceManager.getDefaultSharedPreferences(this);
but I would like those values saved to my current sharedPreferences tag, "MyPrefs", but I'm not sure how to do this.

I love how SharedPreferences work in android and I would like to know if there is an easy way to save them to another file so I could load a previous instance of the prefs and vice versa. Basically when you load this file, all the preferences would change to how you had it before at once. I want to be able to swap 3 or 4 different versions of the same pref keys in this way. Is there an easy way to do this?

We have an online multiplayer game that saves some login information in the SharedPreferences. Our app is copy protected and everything was going really well until this weekend when we released an update for it. It seems that at least some of the people are having their SharedPreferences deleted when they updated too the new app. As you can imagine our users are furious because they're all loosing their profiles, and our ranking is dropping fast.
We've tried to reproduce this a hundreds ways but are unable. We're wondering if this could be related to installing a copy protected app over a copy protected app? Since that's the only situation we haven't tested and can't test.

My first android application has to do with showing activities at different times. All works fine ... except that when I retrieve the shared preferences in an activity activated from the notification manager, all my options are reset to default values.
Similarly, when I try to reinstall an alarm after the phone is switched off, all the previously stored shared preferences options are non-existent.Is there something special that has to be set in the manifest, or do I have to retrieve the context in a special manner? from a broadcastReceiver?

We want to store credentials for a user to a web service so the user doesn't have to repeatedly login, but we're concerned about security. We can't store a hash on the database, but we could probably use JCE encryption locally.
Is the content in SharedPreferences secured on the Android device?

Is it possible to have an external strings.xml or something like that?I'd like to translate my application into several different languages, but the apk would become to large if I include all languages.I would instead like to be able to load languages on demand (from an external URL) and store them on the SD card.Is that possible in any way? How could I in that case use the new language?

In my XML values strings code, I have a string with some text that I want to have only a few of the words in color. I also want to have a new line for some of the text.
I can do things like: < b> my bold text < /b> and that works (leading space added for this post).
I try to tag the text with color but no color shows up and there are no errors.
CODE:.............
I also try adding a new line - I've tried things like:
< LF> some text, space at beginning only for this post < /LF>
< CR> this didn't work either < /CR>
< p> some text, space at beginning only for this post < p>
But, no new paragraph / new line, carriage rtn happens.
