java - SharedPreferences not working as expected, cannot read nor write preferences - 


private void init() {      sharedpreferences prefs = getsharedpreferences("data", context.mode_private);      // set value record      record = prefs.getint("record", 0);      prefs.edit().commit(); }  private void setrecord(int ) {      sharedpreferences prefs = getsharedpreferences("data", context.mode_private);      if(i > prefs.getint("record", 0))         prefs.edit().putint("record", i);      prefs.edit().commit(); }  private int getrecord() {      int rec;      sharedpreferences prefs = getsharedpreferences("data", context.mode_private);      rec = prefs.getint("record", 0);      prefs.edit().commit();      toast toast = toast.maketext(this, rec+"", toast.length_short);     toast.show();      return rec; }

this code should set int , retrieve it, doesn't seem ever set it... can see why that?

think best call interface sharedpreferences.editor edit preferences instead of using prefs.edit().putint("record", i);. docs say...

modifications preferences must go through sharedpreferences.editor object ensure preference values remain in consistent state , control when committed storage.

if change setmethod following should work...

private void setrecord(int ) {      sharedpreferences prefs = getsharedpreferences("data", context.mode_private);     sharedpreferences.editor editor = prefs.edit();      if(i > prefs.getint("record", 0))         editor.putint("record", i);      editor.commit(); }

and guess calling above method setrecord somewhere in code can't see being called anywhere in code snippet pasted.
