Question

I have an ArrayList of string in my activity and i want to store it as onPause in SharedPreference and retrieve it in my onCreate() but i am unable to do that.

here is my code -:

public static ArrayList<String> ignoredTasks;
public static final String PREF_FILE_NAME = "savedPreferences";

@Override
public void onCreate(Bundle savedInstanceState)
{
    ignoredTasks =  loadBackStates();
}
@Override
public void onPause()
{
    super.onPause();
    Log.e(TAG, "I am pause");
    saveState();
}
@Override
public void onStop()
{
    super.onStop();
    Log.e(TAG, "I am stop");
    saveState();
}
@Override
public void onDestroy()
{
    super.onDestroy();
    Log.e(TAG, "i am destroy");
    saveState();
}

public void saveState()
{
    SharedPreferences spr = getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = spr.edit();
    int size = ignoredTasks.size();
    editor.putInt("size", size);
    for(int k = 0; k < size-1; k++)
    {
        editor.putString(k+"4", ignoredTasks.get(k));
        editor.commit();
    }

    //editor.commit();
}
public ArrayList<String> loadBackStates()
{
     ArrayList<String> ignoredTask = new ArrayList<String>();
    SharedPreferences sp = getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE);
    int size = sp.getInt("size", 0);
    for(int k = 0; k < size-1; k++)
    {
        ignoredTask.add(k, sp.getString(k + "4", " "));
    }
    return ignoredTask;

}


public void createMenuDialog(final int i, Drawable icon, final String taskName, final String pkgName)
{
    final AlertDialog.Builder menuDialog = new AlertDialog.Builder(this);
    menuDialog.setIcon(icon);
     menuDialog.setTitle(taskName);
menuDialog.setItems(menuItems, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                    /* User clicked so do some stuff */
                    String[] items = menuItems;

                    if(items[which].equals("Ignore"))
                    {
                        HashMap<String,String> newItem = new HashMap<String,String>();
                        newItem.put("Process", pkgName);
                        newItem.put("Name", taskName);
                        ignored.add(newItem);
                        ignoredTasks.add(pkgName);
                    }                                               
                }
            });
     menuDialog.show();
}

The problem is when i exit my app using back key and then if i restart it again, i could see the sharedpreference but when i force close my app then its gone. what’s the issue?

Please Help!!

Thanks

try this one..

SharedPreferences spr =  activity.getSharedPreferences("SPR", Context.MODE_PRIVATE);

try this – maybe it will help..

for(int k = 0; k < size-1; k++)
{
    editor.putString(k+"4", ignoredTasks.get(k));

}
editor.commit();
