Hi, I tried all ways how many i know.
That is my code block for test. (MainActivity.onCreate()) String REMEMBERME_PREF_NAME = "rememberme"; SharedPreferences sharedpreferences = this.getSharedPreferences(REMEMBERME_PREF_NAME, Context.MODE_PRIVATE); if (sharedpreferences.getString("email", "").equals("")) { Log.d("SHARED PREF", "onCreate() returned: " + "CAN'T REMEMBER"); SharedPreferences.Editor editor = sharedpreferences.edit(); editor.clear(); editor.putString("email", "REMEMBERED"); editor.commit(); } Log.d("SHARED PREF", "onCreate() returned: " + sharedpreferences.getString("email", ":(")); This code working for all new apps or other existing apps but it still doesn't work for my app. What is wrong with my app? Could anybody help me? Thank you. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
