I have an ArrayList with custom objects. Each custom object contains a variety of strings and numbers. I need the array to stick around even if the user leaves

Saving Array in SharedPreferences:

public static boolean saveArray()
{
    SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
    SharedPreferences.Editor mEdit1 = sp.edit();
    /* sKey is an array */
    mEdit1.putInt("Status_size", sKey.size());  

    for(int i=0;i



Loading Array Data from SharedPreferences

public static void loadArray(Context mContext)
{  
    SharedPreferences mSharedPreference1 =   PreferenceManager.getDefaultSharedPreferences(mContext);
    sKey.clear();
    int size = mSharedPreference1.getInt("Status_size", 0);  

    for(int i=0;i
