I have a preference screen where I can change some settings.
In the code I can edit them via the shared preferences without a problem.
I have 2 questions:
– do these settings stay saved somewhere when the phone restarts?
– can I insert other settings into the sharedprefs. I mean settings that are not declared in the preference screen.
do these settings stay saved somewhere when the phone restarts?
Yes they are persisted in an xml file on the device.
can I insert other settings into the sharedprefs?
Yes you can have lots of settings in sharedprefs, the only ones that are displayed or modified through the PreferenceActivity are those you set in your layout file and their keys will be the keys specified in the layout file.
