change PreferenceActivity to PreferenceFragmentCompat in old project

[neuberfran]

Hi,

I need very much your help, even if it is small

I stay taking PreferenceActivity of project links below and I put PreferenceFragmentCompat

https://github.com/ryanfx/GarageAndroid/blob/master/src/com/blogspot/ryanfx/activity/ConfigurationActivity.java

I have issue of the picture below and this is my project (with issue):

https://github.com/neuberfran/AlarmController/blob/master/app/src/main/java/com/blogspot/neuberfran/activity/ConfigurationActivity.java

What about context of the PreferenceFragmentCompat? getActivity() in line 62 in my ConfigurationActivity.java is correct?

What I need do to solve my issue?

This has nothing to do with the library, which I stopped supporting anyway. You should ask this question on StackOverflow instead. If you wish, write here a link to the question there. Please write there a minimal yet working code so that I could understand what is going on.

This doesn't look like the issue you wrote here, of PreferenceActivity and PreferenceFragmentCompat
