Question

I’ve placed a preferences file ‘xml/sleeppreferences.xml’ into a tabSpec, with the idea that that is the preferences for that part of the app and there will be other preference files for other parts.

This seems to work ok. I make a preference change, close the emulator, re-run the app, go back to the preference page, and the preference is what I had set it to.

But when I click to another tab, where I want to use the value of that preference, it all goes wrong.

I’ve looked high and low, but cannot find an answer.

This is an excerpt of the code:

public static final String PREF_FILE_NAME = "sleeppreferences";
:
:
:
SharedPreferences prefs = getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE);        
String test=prefs.getString("editTextPref", "unset");

with “unset” being the default response if it doesn’t find anything.

It always returns “unset”

As I say, I’ve looked all over, and the code I’m using seems to be the correct code. So what’s going on?

Thanks

Answer 1

Try using the GetSharedPreferences of the context class. Something like this:

public  String GetPassword (Context Contexto, String Key) throws Exception
    {       

        SharedPreferences savedSession= Contexto.getSharedPreferences(Key,Context.MODE_PRIVATE);
        return Encryption.decrypt(_Seed,savedSession.getString(Key, null));

    }

I think this should work as well:

getApplicationContext().getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE).getString("editTextPref", "unset");
