Question

In the below code what I am doing is getting spinner item from web service. And on item select, some process is done. The problem is that it is not getting data from a server to spinner.

Frnt_mapActivty1.java

  /*****************************FOR LOCATION FOR**************************************/
//Download JSON file AsyncTask
public class LocationList extends AsyncTask<Void, Void, Void> {
    JSONObject jsonobject;
    JSONArray jsonarray;


@Override
    protected Void doInBackground(Void... params) {
        // Locate the WorldPopulation Class
        worldlocation = new ArrayList<LocationBeams>();
        // Create an array to populate the spinner
        world_locationlist = new ArrayList<String>();
        // JSON file URL address
        jsonobject = JSONfunctions.getJSONfromURL(Wservices.mGetLocationURL);
        try {
            // Locate the NodeList name
            jsonarray = jsonobject.getJSONArray("location");
            for (int i = 0; i < jsonarray.length(); i++) {
                jsonobject = jsonarray.getJSONObject(i);
                LocationBeams worldpop = new LocationBeams();
                worldpop.setTerm_id(jsonobject.optString("term_id"));
                worldpop.setName(jsonobject.optString("name"));
                worldpop.setSlug(jsonobject.optString("slug"));

                worldlocation.add(worldpop);
                world_locationlist.add(jsonobject.optString("name"));
            }
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return null;
    }
    @Override
    protected void onPostExecute(Void args) {
        // Locate the spinner in activity_main.xml
        Spinner mySpinner = (Spinner)findViewById(R.id.spin_location);
        // Spinner adapter
        mySpinner.setAdapter(new ArrayAdapter<String>(Frnt_mapActivity1.this,
                android.R.layout.simple_spinner_dropdown_item,world_locationlist));
        // Spinner on item click listener
        mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> arg0,
                                       View arg1, int position, long arg3) {
                // TODO Auto-generated method stub


                txtlocation.setText(worldlocation.get(position).getSlug());

            }
            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub
            }
        });

        if(mDialog!=null && mDialog.isShowing()){
            mDialog.dismiss();
        }
    }
}

use volley library to call webservice so you can solve all issues — Anand Savjani, Mar 14 '17 at 06:44

Caused by: java.lang.NullPointerException: println needs a message at android.util.Log.println_native(Native Method)

Problem

Log.e("Error", e.getMessage());

e.getMessage() is null

NullPointerException is thrown when an application attempts to use an object reference that has the null value

Check

e.getMessage()==null

Try with

 if(e.getMessage()==null)
 {
    Log.e("Error", " "+e.getMessage());
    e.printStackTrace();
 }
else
 {
   Log.e("Error", e.getMessage());
    e.printStackTrace();
 }

Read NullPointerException : println needs a message in android
