#Poladroid error impossible to save prferences code#

My code was more or less as follows: (comboToSave is simply a string generated by Gson from a simple data class) I never checked whether the data actually went into the file so I have no idea whether there was a failure on Save or Load or both. I could see the String being saved, no errors in LogCat and yet when I try to load it, again with no error, my String is empty. I had my Save and Load code in a class that extends Application because I wanted a single instance of my data. I too had a problem with saving and then retrieving data.

I can post the real code here also once it's ready and someone is interested. I was thinking of something like this: // !! I know that 2.6.32.9 is not yet correct. So it can be considered as crucial to implement a workaround for saving preferences.įor collecting detailed characteristics to isolate this workaround in a sharp-edged way, could everyone who is also facing that issue please provide the corresponding kernel version ( System.getProperty('os.version') here? The strange behavior is that either SharedPreferences are not saved, or, as after a factory reset, they're too persistent, that is to say they are not deleted after having reinstalled the application.ĭue to the current distribution of 2.2.x, and the number of Samsung Galaxy S devices sold being several millions, the probability of an occurrence of this issue is significant. The Device used is a Samsung Galaxy S with SDK level 8 (2.2.1). On the client's main test device I came across the very same issue. I wasted a lot of my time trying to figure this out, and I hope it helps someone else. Since it is not my phone, I haven't tried it yet, but I assume a Factory Data reset would fix it completelyĮDIT: I was able to test on both a new Samsung Captivate and a Samsung infuse, and it worked. They stayed both when I manually set them using: PreferenceManager.getDefaultSharedPreferences() Īnd without manually saving them to the SharedPreferences. I then power cycled the phone and the settings were still there like I'd configured them. I then installed TestProj on the Samsung Captivate, changed the settings around, cleared the ram through RAM management (a function of the custom ROM I have), and the settings stuck. I created a new project called 'testproj', then I copied ALL the code from my settings PreferenceActivity, pasted it into the TestprojActivity, and I copied the code from the xml it relied on, then pasted that into the main.xml of TestProj.

There's no code error on my part, and there is no issue with my app whatsoever (I don't believe, anyway.)

I then tried changing the key value of m圜heckBoxPreference to something that did NOT match the xml key for the CheckBoxPreference, and it still had the same effect.Īnd I uninstalled the application from the phone, then powered the phone off and back on, and then re-installed, and it still has the same effect. Same behavior, ntains still returns true if I just close the app and open it back up, but it returns false if I power the phone off and back on. In the class declaration: public static final String PREFS = 'prefs' Īnd in the onResume(): SharedPreferences pref = this.getSharedPreferences(PREFS, 0) So I then tried using a SharedPreferences file. Still, if I close the app and open it back up, ntains returns true, but if I power cycle the phone off and back on, it returns false. I also tried calling it in onStop and onPause. So, I tried manually setting the SharedPreference SharedPreferences.Editor editor = pref.edit() Įditor.putBoolean('m圜heckBoxPreference', m圜heckBoxPreference.isChecked()) Īnd then I called that when the checkboxpreference value changed. if I close with the task manager or power cycle the phone off and on, then that returns false. When I close out and open it back up, it returns true. I then check to see if there is a key in that sharedpreference. SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()) So, I created a SharedPreference in my onResume() to test it. If I close the app and open it back up, my values remain like they are suppose to, but if I use task manager to end the app or if I power cycle the phone (when the app is not running) then the defaultValues are called again. This does not happen like it's suppose to.

The checkBoxPreference is suppose to save the the default shared preferences file, and then be called again when I open the app in order to update the UI. I have a preferenceActivity in which I have many checkBoxPreferences. EDIT: The problem described below was due to a very peculiar device issue not caused by any coding-related problem.
