      client.sendAsync(restRequest, new AsyncRequestCallback() {
          @Override
          public void onSuccess(RestRequest request, RestResponse result) {
              try {
                  listAdapter.clear();
                  JSONArray records = result.asJSONObject().getJSONArray("records");
                  for (int i = 0; i &lt; records.length(); i++) {
                      listAdapter.add(records.getJSONObject(i).getString("Name"));
                  }                   
              } catch (Exception e) {
                  onError(e);
              }
          }
  
          @Override

              Toast.makeText(MainActivity.this,
                             MainActivity.this.getString(SalesforceSDKManager.getInstance().getSalesforceR().stringGenericError(), exception.toString()),
                             Toast.LENGTH_LONG).show();
          }
      });
  }

  <p>first error is </p>
  
  <pre><code>  api_version cannot be resolved or is not a field
  </code></pre>
  
  <p>and second error is </p>
  
  <pre><code>  The type com.android.volley.Request cannot be resolved. It is indirectly referenced from required .class files
  </code></pre>
