How integrate Paypal in android Application?
I try to integrate paypal with Android app using sandbox. I'm getting successfully longing with paypal but when I am doing payment then Screen will get invisible directly without Response.
How can I get the response for the above question?
This is my code.
private void invokeSimplePayment()
{
try
{
PayPalPayment payment = new PayPalPayment();
payment.setSubtotal(new BigDecimal(Amt));
payment.setCurrencyType(Currency_code[code]);
payment.setRecipient("Rec_Email");
payment.setPaymentType(PayPal.PAYMENT_TYPE_GOODS);
Intent checkoutIntent = PayPal.getInstance().checkout(payment, this);
startActivityForResult(checkoutIntent, request);
}
catch (Exception e)
{
e.printStackTrace();
}
}
public void onActivityResults(int requestCode, int resultCode, Intent data)
{
switch(resultCode)
{
case Activity.RESULT_OK:
resultTitle = "SUCCESS";
resultInfo = "You have successfully completed this " ;
//resultExtra = "Transaction ID: " + data.getStringExtra(PayPalActivity.EXTRA_PAY_KEY);
break;
case Activity.RESULT_CANCELED:
resultTitle = "CANCELED";
resultInfo = "The transaction has been cancelled.";
resultExtra = "";
break;
case PayPalActivity.RESULT_FAILURE:
resultTitle = "FAILURE";
resultInfo = data.getStringExtra(PayPalActivity.EXTRA_ERROR_MESSAGE);
resultExtra = "Error ID: " + data.getStringExtra(PayPalActivity.EXTRA_ERROR_ID);
}
System.out.println("Result=============="+resultTitle);
System.out.println("ResultInfo=============="+resultInfo);
}
Answer
This is my code and it works fine. There are two classes.
For PayPal from sandbox to live environment you have to do 2 things: put the actual account holder in set recipient and get a live ID by submitting your app to PayPal
public class ResultDelegate implements PayPalResultDelegate, Serializable {
private static final long serialVersionUID = 10001L;
public void onPaymentSucceeded(String payKey, String paymentStatus) {
main.resultTitle = "SUCCESS";
main.resultInfo = "You have successfully completed your transaction.";
main.resultExtra = "Key: " + payKey;
}
public void onPaymentFailed(String paymentStatus, String correlationID,
String payKey, String errorID, String errorMessage) {
main.resultTitle = "FAILURE";
main.resultInfo = errorMessage;
main.resultExtra = "Error ID: " + errorID + "\nCorrelation ID: "
+ correlationID + "\nPay Key: " + payKey;
}
public void onPaymentCanceled(String paymentStatus) {
main.resultTitle = "CANCELED";
main.resultInfo = "The transaction has been cancelled.";
main.resultExtra = "";
}
The main class :
public class main extends Activity implements OnClickListener {
// The PayPal server to be used - can also be ENV_NONE and ENV_LIVE
private static final int server = PayPal.ENV_LIVE;
// The ID of your application that you received from PayPal
private static final String appID = "APP-0N8000046V443613X";
// This is passed in for the startActivityForResult() android function, the value used is up to you
private static final int request = 1;
public static final String build = "10.12.09.8053";
protected static final int INITIALIZE_SUCCESS = 0;
protected static final int INITIALIZE_FAILURE = 1;
