    @Override

            mListPreference = (ListPreference) getPreferenceManager().findPreference("preference_key");
    
            return inflater.inflate(R.layout.activity_main, container, false);

Devices:

Oppo N1, Android 4.2.2
Samsung Galaxy Note 1, Android 5.1.1

I've spent now hours and hours for this error and couldn't find it. The clue is that exactly the same app is working perfectly on Android 5.1.1.

Answer 1

<fragment
     android:id="@+id/fragment_drawer"
     android:name="com.android.app.NavigationDrawerFragment"
     android:layout_width="@dimen/navigation_drawer_width"
     android:layout_height="match_parent"
     android:fitsSystemWindows="true"/>

use this rather, and inflate the layout in your onCreateView() android will take care of adding it ViewGroup/window etc etc

it is this line in your MainActivity

 // Set up the drawer.
    mNavigationDrawerFragment.setup(R.id.fragment_drawer, 
             (DrawerLayout) findViewById(R.id.drawer), mToolbar);

remove it and the error will go. Now the next thing is you let the Activity handle the Drawerlayout himself. so transfer all drawer codes to your activity and forget the setup() method in your fragment

The reason is since you declared the fragment as embeded in the Activity, android initiates it for you, so you do not need to set it up

hope it works

Answer 2

Well you all helped me a lot, but I fixed it by myself ;)

I changed..

public class FragmentSettings extends PreferenceFragment {

    public ListPreference mListPreference;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        mListPreference = (ListPreference) getPreferenceManager().findPreference("preference_key");
        return inflater.inflate(R.layout.activity_main, container, false);
    }
}

To..

public class FragmentSettings extends PreferenceFragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
    }

}

And removed with this onCreateView and mListPreference :) Hope this help others ;)

Add this line into your styles.xml file.

<item name="preferenceTheme">@style/PreferenceThemeOverlay</item>
