I am implementing the new billing API 2.0 which has this purchase acknowledge method. Earlier i was using AIDL for my purchase and i had following use case is that i used to pass developer payload during initiating purchase and used to get back my developer payload in the response as a part of purchase object.

Bundle bundle = mService.getBuyIntent(3, "com.example.myapp",
   MY_SKU, "subs", developerPayload);

PendingIntent pendingIntent = bundle.getParcelable(RESPONSE_BUY_INTENT);
if (bundle.getInt(RESPONSE_CODE) == BILLING_RESPONSE_RESULT_OK) {
   // Start purchase flow (this brings up the Google Play UI).
   // Result will be delivered through onActivityResult().
   startIntentSenderForResult(pendingIntent, RC_BUY, new Intent(),
       Integer.valueOf(0), Integer.valueOf(0), Integer.valueOf(0));
}

and in my on on activity result i used to get purchase object 

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
   if (requestCode == 1001) {           
      int responseCode = data.getIntExtra("RESPONSE_CODE", 0);
      String purchaseData = data.getStringExtra("INAPP_PURCHASE_DATA");
      String dataSignature = data.getStringExtra("INAPP_DATA_SIGNATURE");

      if (resultCode == RESULT_OK) {
         try {
            JSONObject jo = new JSONObject(purchaseData);
            String sku = jo.getString("productId");
            alert("You have bought the " + sku + ". Excellent choice, 
               adventurer!");
          }
          catch (JSONException e) {
             alert("Failed to parse purchase data.");
             e.printStackTrace();
          }
      }
   }
}

This purchase object has a developer payload which i send to the server for verification.

Now in the new API the developer payload can be added only after purchase is completed or when we consume a purchase, so the problem is after purchase is acknowledged i need the updated purchase object but how to get it?

 if (!purchase.isAcknowledged()) {
            AcknowledgePurchaseParams acknowledgePurchaseParams =
                AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .setDeveloperPayload(/* my payload */)
                    .build();
            client.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
        }

In acknowledgePurchaseResponseListener i get only the response code whether it is success or failure. But i need to updated purchase object object with developerPayload and isAcknowledged flag true.

Is there a way to do so? Could not find anything in documentation.

The local cache of purchases is updated by the time your acknowledgePurchaseResponseListener is called so you can query the purchase from the cache using https://developer.android.com/reference/com/android/billingclient/api/BillingClient.html#querypurchases. We will consider adding the update purchase to the listener for a future library release to make this more convenient.
