Please guide me in this issue.

I am able to diplay the gridview with images.

I get force close error when i select image in gridview

Ummm, I think I have find the problem. It's here:

 public void onItemClick(AdapterView parent,View arg1, int arg2, long arg3) {  
              //         public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                                // TODO Auto-generated method stub
                                SharedPreferences myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
                                SharedPreferences.Editor prefsEditor = myPrefs.edit();
                                System.out.println("Emoji is:- " +arg2);
                                prefsEditor.putInt("key1", arg2);
                                prefsEditor.commit();
                              //  finish();

                dialog.hide();
                        }

                        private SharedPreferences getSharedPreferences(String string,
                                        int modeWorldReadable) {
                                // TODO Auto-generated method stub
                                return null;
                        }
              });

Your SharedPreference Object it's null, and you are treating to access to it.

 private SharedPreferences getSharedPreferences(String string,
                                            int modeWorldReadable) {
                                    return null;
                            }

You need to return something, for example:

private SharedPreferences getSharedPreferences(String string,
                                            int modeWorldReadable) {
                                    return PreferenceManager.getDefaultSharedPreferences(context); //You need to pass an Context object, don't forget it
                            }

I hope that helps you.
