I have a similar problem like this, so I proceeded according to the proposed solution and added this line of code to onCreate:

PreferenceManager.setDefaultValues(this, R.xml.settings, false);

Unfortunately the problem still occurs, if the user hasn’t altered the settings, still the default-value (true) from

mPreferences.getBoolean(String.valueOf(day_of_week), true)

is used instead of the default value from the XML.

One proposed to change the default-value parameter of getBoolean() to null, but this code crashes the app:

mPreferences.getBoolean(String.valueOf(day_of_week), (Boolean) null)

Any advice? Thanks in advance!

    Finally it works! I really put much time and effort into searching for the error and as soon as I post here, I find it out alone ~~ thanks guys for helping me with this one.

    If ever anyoneelse has this problem, the solution goes like this: Change the default Value of getBoolean() from true to false like so:

    mPreferences.getBoolean(String.valueOf(day_of_week), true) -> doesn’t work, it is always true no matter what happened in the XML

    mPreferences.getBoolean(String.valueOf(day_of_week), false) -> it works! It’s the correct default Value from the XML

    I really don’t understand the logic into doing this, but now it works perfectly. Seems a bit like a bug to me.
