I am currently following this tutorial Android Settings
my problem is it save the app settings as
Although you can rename the preference file but you should not do that. Actually, the exact location and name of this preference file is not documented, so I'd suggest you don't rely on some conventions when trying to access this file directly, since the location and name may be changed in future -
SharedPreferences should be the only way to access this file.And your App will stop working.
Anyhow here is the way to rename your preference file
String fileName="mychoosennamehere_preferences"; File f=new File("/data/data/eywa.musicplayer/shared_prefs/"+"com.packagename_preferences"+".xml"); f.renameTo(new File("/data/data/eywa.musicplayer/shared_prefs/"+fileName+".xml")); SharedPreferences mySharedPreferences=getSharedPreferences(fileName,Activity.MODE_PRIVATE); SharedPreferences.Editor editor = mySharedPreferences.edit(); editor.remove(PlayListName); editor.putString(fileName, fileName); editor.commit(); PlayListName=fileName;
