 Hi, All:
My android app is responsible for uninstall the specified packages. Is there
an "intent" for this?
With many thanks.

1. Handler Exception when trying to get Spinner selected Item

Hello,

I am trying to get the selected item of my spinner that is populated
and I am already seeing the values. when I try to use
(String) s.getSelectedItem(); to get the selected item, I am receiving
a handler exception on Logcat.

The spinner throwing the error is a 2nd spinner resulting from the 1st
spinner's selected item (that works perfectly). In other words, user
selects from spinner one and upon selection, populates spinner 2
(until here everything is fine). When trying to get the value of the
selected row in spinner2 , I am receiving the error.

here's the main parts of my code:

    @Override
        public void onCreate(Bundle icicle) {

        super.onCreate(icicle);
        setContentView(R.layout.main);


        // The drop down list for the list of universities
        final Spinner s = (Spinner) findViewById(R.id.spinner);
            ArrayAdapter adapter = ArrayAdapter.createFromResource(
                    this, R.array.universities,
android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
            s.setAdapter(adapter);

            // Initialization of the 2nd spinner
            String[] array = {"this", "is", "driving", "me", "crazy"};
                final Spinner s2 = (Spinner) findViewById(R.id.spinner2);
                ArrayAdapter<String> cadapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, array);
                cadapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
                s2.setAdapter(cadapter);
 // When user selects a university
            s.setOnItemSelectedListener(new OnItemSelectedListener() {

                        @Override
                        public void onItemSelected(AdapterView<?> arg0, View 
arg1,
                                        int arg2, long arg3) {
                                  //Get the selected university
                                   String selectedItemString = (String) 
s.getSelectedItem();
                                 //  System.out.println
("Uni: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"+selectedItemString);

                          if(selectedItemString .equals(""))
                          {
                                  // In case of an error so it won't crash
                                  nospinner();
                          }

                          else
                          {
                                  // Find the table of the selected University 
dynamically
                                 finder(selectedItemString);
                          }

                        }

                        @Override
                        public void onNothingSelected(AdapterView<?> arg0) {

                        }




       });

         // When user selects a university
                s2.setOnItemSelectedListener(new OnItemSelectedListener() {

                                @Override

View arg1,
                                                int arg2, long arg3) {

                        //                      String selected  =

crashes here
                                //              System.out.println

                                }

                                @Override

                                }
               });

     }

protected void finder(String selectedItemString) {


               final Dbadapter db = new Dbadapter(this);  // This creates an
instance of the database in this class
           final Spinner s2 = (Spinner)findViewById(R.id.spinner2);

                   db.open();

                   // Fix selected item to match the db
                   selectedItemString = (selectedItemString).toLowerCase();
                   selectedItemString = selectedItemString.replaceAll(" ","");


                   // Call a function to return the rows of that university
                   final Cursor cur = db.getAllTitles(selectedItemString);
                //cur.moveToFirst();
