Flutterwave Android payment integration - cannot process payment - error unable to retrieve transaction fee

I'm using Rave for the first time, it looked so flexible and easier to integrate, but along the line. I got stuck with testing, I'm using only card and bank payments methods.
when I choose the card to and enter some test cards from the test card link https://developer.flutterwave.com/reference#test-cards-1
I get 2 errors, => "unable to retrieve transaction fees" but in my logcat I see => " only test cards ree allowed," of which were using the test cards. And am also on staging mode which I assume is correct while testing with test keys.
When I use the bank tab I get some error in JSON toasted, but display later => "parents_limit not defined". Not just that I give this errors, I still found transactions of the bank payment types recorded on my dashboard. This confuses me more since I didn't get the payment success message so I can verify and give value to the customer.
I have integrated everything as per guideline in Rave docs, which calls my make payment. from https://github.com/Flutterwave/rave-android
variable for implementation
//online payment
String[] fullname;
String email = "";
String fName = "";
String lName = "";
String narration = "Payment for Riidit App activation";
String txRef;
String country = "NG";
String currency = "NGN";
private String mUsername, userID, mEmail;
the payment method
private void makePayment(int amount) {
txRef = email + " " + UUID.randomUUID().toString();
try {
fullname = mUsername.split(" ");
fName = fullname[0];
lName = fullname[1];
} catch (NullPointerException ex) {
ex.printStackTrace();
}
/*
Create instance of RavePayManager
*/
new RavePayManager(this).setAmount(amount)
.setCountry(country)
.setCurrency(currency)
.setEmail(email)
.setfName(fName)
.setlName(lName)
.setNarration(narration)
.setPublicKey(RiiditUtilTool.getPublicKey())
.setEncryptionKey(RiiditUtilTool.getEncryptionKey())
.setTxRef(txRef)
.acceptAccountPayments(true)
.acceptCardPayments(true)
.acceptMpesaPayments(false)
.acceptGHMobileMoneyPayments(false)
.onStagingEnv(false)
.allowSaveCardFeature(true)
.withTheme(R.style.DefaultTheme)
.initialize();
}
//called from below
private void payOnline()
{
makePayment(amount);
}
public void onActivateOnlineClick(View v) {
payOnline();
}
// expecting result of payment here either fail or success
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RaveConstants.RAVE_REQUEST_CODE && data != null) {
String message = data.getStringExtra("response");
if (resultCode == RavePayActivity.RESULT_SUCCESS) {
Toast.makeText(this, "SUCCESS " + message, Toast.LENGTH_LONG).show();
// get a PIN and SERIAL no when payment succeeds
getGetPinAndSerialForPaidUser();
} else if (resultCode == RavePayActivity.RESULT_ERROR) {
Toast.makeText(this, "ERROR " + message, Toast.LENGTH_LONG).show();
} else if (resultCode == RavePayActivity.RESULT_CANCELLED) {
Toast.makeText(this, "Payment CANCELLED " + message, Toast.LENGTH_LONG).show();
}
}
}
I want when this event is triggered, it will make the payment to using the value set in the amount and return status in the onActivityResult above where I can check and give value to the user

First of all make sure you are using the api keys which are for testing and if you are on staging mode(testing) then set this to true .onStagingEnv(true) and test after that.

Capture Paypal Payment in android

I have authorized Paypal amount using PayPalPayment.PAYMENT_INTENT_AUTHORIZE intent in PaymentActivity now i have authorizationId but how to capture this amount now?
Code to start PaymentActivity
PayPalPayment thingToBuy = getStuffToBuy(PayPalPayment.PAYMENT_INTENT_AUTHORIZE);
/*
* See getStuffToBuy(..) for examples of some available payment options.
*/
Intent intent = new Intent(SampleActivity.this, PaymentActivity.class);
// send the same configuration for restart resiliency
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);
startActivityForResult(intent, REQUEST_CODE_PAYMENT);
onActivityResult
if (requestCode == REQUEST_CODE_PAYMENT) {
if (resultCode == Activity.RESULT_OK) {
PaymentConfirmation confirm =
data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
ProofOfPayment proof = confirm.getProofOfPayment();
PayPalPayment payment = confirm.getPayment();
payment.enablePayPalShippingAddressesRetrieval(true);
JSONObject object = proof.toJSONObject();
String authID = "";
try {
authID = object.getString("authorization_id");
} catch (JSONException e) {
e.printStackTrace();
}
if (confirm != null) {
try {
Log.i(TAG, confirm.toJSONObject().toString(4));
Log.i(TAG, confirm.getPayment().toJSONObject().toString(4));
/**
* TODO: send 'confirm' (and possibly confirm.getPayment() to your server for verification
* or consent completion.
* See https://developer.paypal.com/webapps/developer/docs/integration/mobile/verify-mobile-payment/
* for more details.
*
* For sample mobile backend interactions, see
* https://github.com/paypal/rest-api-sdk-python/tree/master/samples/mobile_backend
*/
displayResultText(authID);
} catch (JSONException e) {
Log.e(TAG, "an extremely unlikely failure occurred: ", e);
}
}
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.i(TAG, "The user canceled.");
} else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID) {
Log.i(
TAG,
"An invalid Payment or PayPalConfiguration was submitted. Please see the docs.");
}
}
Now I have authorization id in authId now i want to capture this amount. Can I do this within my app without any server side work.

Make a post request to https://api.sandbox.paypal.com/v1/oauth2/token
2.Set the Authorization type to Basic Auth and then set the client_id into the Username field and secret into the Password field.
3.Set the Body to x-www-form-urlencoded and then set grant_type in the key field and client_credentials in the value field.
In response to above you will get an access token.
Now make GET request to https://api.sandbox.paypal.com/v1/payments/payment/PAY-5YK922393D847794YKER7MUI with Headers, Content-Type -- application/json" and Authorization -- Bearer accessToken_you_get_in_above_call .(PAY-5YK922393D847794YKER7MUI this is your payment id)
In response of above you will get an object as "state": "approved", if it is approved means your payment has been successfully done.
Note:- In the first response you will get an access token, but this token is valid for only few seconds , so you have to get another access token if it is expired.

Android InAppBilling PurchaseStatusAPI

I want to establish a content provider server whose different contents have to be bought using the Android InAppBilling API. If a mobile user buys an item he gets a unique purchase token. If the user wants to download some content from my server I can use that token to check if the purchase is valid and thus the user is allowed to download the content.
But how do I check if that purchase token really belongs to the user my server is talking to? Is there an existing authentication mechanism?

as you can see at the end of image there are "response code" you can use it like developer docs
#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();
}
}
}
}
if not enough also you can check In-app Billing Reference (IAB Version 3)
well I am trying to help not a prof..

How to detect In-App Purchase's Status on Activity Result Method

I am testing In-App Purchase using Static References.
I am using the Static Reference android.test.purchased but i can't figure out how to get the response of the Test Purchase in my onActivityResult(...) Method.
Here is my onActivityResult(....) Method's Body:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Log.d("In-App", "Data = "+data.toString());
Log.d("In-App", "Request Code = "+requestCode);
Log.d("In-App", "Result Code = "+resultCode);
}
My Logcat says:
08-16 10:48:10.114: D/In-App(3889): Data = Intent { (has extras) }
08-16 10:48:10.114: D/In-App(3889): Request Code = 666
08-16 10:48:10.114: D/In-App(3889): Result Code = -1
Screen Shots of my Test Purchase:
1.
2.
The question is that, what extras should i extract from the Data Object in my onActivityResult(....) method, to detect the status of the current test purchase (Canceled, already purchased, Successfully accepted, etc) and the information about the product (JSON respnse)?
Any help is highly appreciated, thanks.

I have updated my onActivityResult(...) Method
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) {
//Purchased Status = Purchased
try {
//Product Details JSON
JSONObject jo = new JSONObject(purchaseData);
//Purchased Product ID
String sku = jo.getString("productId");
}
catch (JSONException e) {
e.printStackTrace();
}
}
else {
//Purchased Status = Not Purchased
}
This way i have got the purchase's status and the purchased product's details JSON.

First of all, you need a database to persist the orders. Second of all, when the user install the your app. You have to issue a RESTORE_TRANSACTIONS what the user has bought and insert the result into the local database. you can read more HERE.
