thingspeak jsonをアンドロイドに渡すことができません

Question

センサー読み込みをbmp180にして、thingspeakに渡しグラフを表示しました。今度はアンドロイドフォンにthingpeakのjsonを取得したいのですが、thingpeakデータのjsonは入っていません私phone.Anyヘルプはappreciated.Hereだろう私のコードです：

public class MainActivity extends Activity { 

private static final String PATIENTS_LIST_URL = "http://thingspeak.com/channels/201342/field/1.json"; 

ArrayList<HashMap<String, String>> patientList; 

Button button; 
    TextView textview; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     textview=(TextView) findViewById(R.id.textView); 
     button = (Button) findViewById(R.id.button_get_string); 
     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       GetJsonData(); 
      } 
     }); 

    } 

private void GetJsonData() { 
    final JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST, 
      PATIENTS_LIST_URL, null, new Response.Listener<JSONObject>() { 

     @Override 
     public void onResponse(JSONObject response) { 
     // Toast.makeText(MainActivity.this, response.toString(), Toast.LENGTH_SHORT).show(); 
      textview.setText(response.toString()); 

      try { 

       JSONArray data = response.getJSONArray("feeds"); 

      JSONObject eachData = data.getJSONObject(0); 
      String address=eachData.getString("field2"); 

      // Toast.makeText(getApplicationContext(), 
        // "field1::"+address, Toast.LENGTH_SHORT).show(); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
     } 
    }, 
      new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        error.printStackTrace(); 
        // Snack(error.getMessage()); 
       } 
      } 
    ) { 
     @Override 
     protected Map<String, String> getParams() throws AuthFailureError { 
      Map<String,String>map = new HashMap<String,String>(); 
      return map; 
     } 
    }; 

    RequestQueue requestQueue = Volley.newRequestQueue(this); 
    requestQueue.add(jsonObjReq); 
} 
}
