I have used in my project it's working perfect..
Preferences = getSharedPreferences("here is your preferences name", Context.MODE_PRIVATE);
- editor = preferences.edit();
- editor.clear();
- editor.commit();

I am using facebook api in my app. Its working fine i can login and post on wall. But i couldn't delete the login information.
This is the code
public boolean saveCredentials(Facebook facebook) { Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit(); editor.putString(TOKEN, facebook.getAccessToken()); editor.putLong(EXPIRES, facebook.getAccessExpires()); return editor.commit(); } public boolean restoreCredentials(Facebook facebook) { SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE); facebook.setAccessToken(sharedPreferences.getString(TOKEN, null)); facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0)); return facebook.isSessionValid(); } public boolean removeCredentials() { SharedPreferences prefs = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE); facebook.setAccessToken(prefs.getString("", null)); facebook.setAccessExpires(prefs.getLong("", 0)); Editor editor = prefs.edit(); editor.clear(); editor.commit(); return true; }
The Shared preferences details hasn't deleted by calling
removeCredentials()
method. It just post the message on facebook wall.I just want to delete the saved details and if again user requests to posting the message on wall then i need to popup the login screen.
Thanks for your Help guys
