Samsung Developing Smartwatch That Works Without a Smartphone

  Samsung is working on a Smart watch that doesn't need to sync with smartphone to work .

A report says that south Korean manufacturer is in talk with various telecommunications carriers that would turn the smart watch into phone itself.

User will be able to make call by holding the smart watch to the mouth.

Although most on the market right now need to be tethered to a 

smartphone to receive phone calls, send text messages, check email and use other features, Samsung has its sights set on creating a smart watch that doesn't need a smartphone to work.

 

The Smart watch will  reportedly run on Samsung's tizen Smart watch  operating system.

Samsung's second-generation Gear 2 is lighter,thinner and more powerful- overall it works better than previous model.  

The Samsung smart watch is said to be launch in June or July.

    String[] countries = new String[] {

        "Bangladesh",

        "Nepal",

        "Afghanistan",

        "North Korea",

        "South Korea",

        "Japan"

    };

 

    // Array of booleans to store toggle button status

    public boolean[] status = {

        true,

        false,

        false,

        false,

        false,

        false,

        false,

        false,

        /** Restore from the previous state if exists */

        if(savedInstanceState!=null){

            status = savedInstanceState.getBooleanArray("status");

        }

 

        ListView lvCountries = (ListView) findViewById(R.id.lv_countries);

 

        OnItemClickListener itemClickListener = new OnItemClickListener() {

            @Override

            public void onItemClick(AdapterView<?> lv, View item, int position, long id) {

 

                ListView lView = (ListView) lv;

 

                SimpleAdapter adapter = (SimpleAdapter) lView.getAdapter();

 

                HashMap<String,Object> hm = (HashMap) adapter.getItem(position);

 

                /** The clicked Item in the ListView */

                RelativeLayout rLayout = (RelativeLayout) item;

 

                /** Getting the toggle button corresponding to the clicked item */

                ToggleButton tgl = (ToggleButton) rLayout.getChildAt(1);

 

                String strStatus = "";

                if(tgl.isChecked()){

                    tgl.setChecked(false);

                    strStatus = "Off";

                    status[position]=false;

                }else{

                    tgl.setChecked(true);

                    strStatus = "On";

                    status[position]=true;

                }

                Toast.makeText(getBaseContext(), (String) hm.get("txt") + " : " + strStatus, Toast.LENGTH_SHORT).show();

            }

        };

 

        lvCountries.setOnItemClickListener(itemClickListener);

 

        // Each row in the list stores country name and its status

        List<HashMap<String,Object>> aList = new ArrayList<HashMap<String,Object>>();

 

        for(int i=0;i<10;i++){

            HashMap<String, Object> hm = new HashMap<String,Object>();

            hm.put("txt", countries[i]);

            hm.put("stat",status[i]);

            aList.add(hm);

        }

 

        // Keys used in Hashmap

        String[] from = {"txt","stat" };

 

        // Ids of views in listview_layout

        int[] to = { R.id.tv_item, R.id.tgl_status};

 

        // Instantiating an adapter to store each items

        // R.layout.listview_layout defines the layout of each item

        SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.lv_layout, from, to);

 

        lvCountries.setAdapter(adapter);

    }

 

    /** Saving the current state of the activity

    * for configuration changes [ Portrait <=> Landscape ]

    */

    @Override

    protected void onSaveInstanceState(Bundle outState) {

        super.onSaveInstanceState(outState);
