Use below code to store value into sharedpreferences.

SharedPreferences myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
SharedPreferences.Editor prefsEditor = myPrefs.edit();
prefsEditor.putLong("Value", mLongValue);
prefsEditor.commit();

Use below code for retrive long value from sharedpreferences.

SharedPreferences myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
long mVal = myPrefs.getLong("Value", 0.0);
