title: Can't remove SharedPreferences
body: <p>First, I was using Shared preferences for my application for sending data from one activity to another, when listview is clicked in first activity, but I have a trouble when I click another list, the detail from that other list is the same as the first.<br>
  When I try to use intent, it's still the same. I have used:</p>
  
  <pre><code>settings.edit().clear().commit();
  </code></pre>
  
  <p>and </p>
  
  <pre><code>settings.edit().remove().commit();
  </code></pre>
  
  <p>but it doesn't work. is there any wrong? this is my first activity :</p>
  
  <pre><code>lv.setOnItemClickListener(new OnItemClickListener() {
              @Override
              public void onItemClick(AdapterView&lt;?&gt; parent, View view,
                      int position, long id) {
  //              SharedPreferences settings = getSharedPreferences("PREFS_NAME", 0);
  //              settings.edit().clear().commit();
  //              settings.edit().remove("nama").commit();
  //              settings.edit().remove("alamat").commit();
  //              settings.edit().remove("ket").commit();
  //              settings.edit().remove("img_id").commit();
  //              settings.edit().remove("telp").commit();
  //              settings.edit().remove("begdate").commit();
  //              settings.edit().remove("enddate").commit();
  
                  Intent detail= new Intent (TerbaruSimasCard.this, TerbaruDetail.class);
                  detail.putExtra("nama", nama);
                  detail.putExtra("alamat",alamat);
                  detail.putExtra("ket", ket);
                  detail.putExtra("telp",telp);
                  detail.putExtra("begdate", begdate);
                  detail.putExtra("enddate",enddate);
                  detail.putExtra("img_id", img_id);
  
  //              SharedPreferences settings = getSharedPreferences("PREFS_NAME", 0);
  //              settings.edit().clear().commit();
  //              startActivity (detail);
  //              Intent detail= new Intent (TerbaruSimasCard.this, TerbaruDetail.class);
                  startActivity (detail);
  
  //              SharedPreferences settings = getSharedPreferences("PREFS_NAME", 0);
  //              SharedPreferences.Editor editor = settings.edit();
  //              editor.putString("nama", nama);
  //              editor.putString("alamat",alamat);
  //              editor.putString("ket", ket);
  //              editor.putString("telp",telp);
  //              editor.putString("begdate", begdate);
  //              editor.putString("enddate",enddate);
  //              editor.putString("img_id", img_id);
  //              editor.commit();
  //              System.out.println(nama+"nama");
  
              }
  </code></pre>
  
  <p>This is my second activity :</p>
  
  <pre><code>Intent detail= getIntent();
          nama=detail.getStringExtra("nama");
          alamat= detail.getStringExtra("alamat");
          ket= detail.getStringExtra("ket");
          img_id= detail.getStringExtra("img_id");
          telp= detail.getStringExtra("telp");
          begdate= detail.getStringExtra("begdate");
          enddate= detail.getStringExtra("enddate");
  
  //      SharedPreferences settings = getSharedPreferences("PREFS_NAME", 0);
  //      settings.edit().clear().commit();
  //      settings.edit().remove("nama").commit();
  //      settings.edit().remove("alamat").commit();
  //      settings.edit().remove("ket").commit();
  //      settings.edit().remove("img_id").commit();
  //      settings.edit().remove("telp").commit();
  //      settings.edit().remove("begdate").commit();
  //      settings.edit().remove("enddate").commit();
  //      nama= settings.getString("nama", null);
  //      alamat = settings.getString("alamat", null);
  //      ket= settings.getString("ket", null);
  //      img_id = settings.getString("img_id", null);
  //      telp= settings.getString("telp", null);
  //      begdate = settings.getString("begdate", null);
  //      enddate = settings.getString("enddate", null);
  </code></pre>
  
  <p>I have force stopped, cleared cache of my application and uninstall it, but it still doesn't work.
  Is there any wrong with my method?  </p>
