Question

I am running into an issue with Shared preferences. It isn’t working as I expected. Upon login of my application I store an id (google id) in the shared preferences. On a subsequent activity (about 3 activities later) I attempt to retrieve the id but it is null. In case it is important, I am attempting to retreive the shared preferences in a onClickListener (from a button). I am not sure what I am doing wrong. Any help would be appreciated.

How I am setting it:

    public void setLoginPreferences(String id){

    SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();
    editor.putString(Constants.ID_KEY_NAME, id);
    editor.commit();
}

How I am attempting to get it:

    //setup clickListener for Sumbit Comment
    Button submitButton = (Button) findViewById(R.id.submitComment);
    submitButton.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View v) {
           //myContext is a global variable set on the onCreate of the activity
            SharedPreferences prefs = myContext.getPreferences(MODE_PRIVATE);
            String userId = prefs.getString(Constants.ID_KEY_NAME, null);   
            SetConcertCommentAsynchWebservice scca = new SetConcertCommentAsynchWebservice(myContext,concertId,userId,Float.toString(soundRatingBar.getRating()),Float.toString(showRatingBar.getRating()),userSubmittedComments.getText().toString()); 
        }});
}

Answer 1

you may want to use context.getSharedPreferences() instead of context.getPreferences(), if you want to access them somewhere else.
