Android Paypal Gateway Example | Paypal demo in android | Pay inside App using Paypal and Credit card


Hi Friends, in past we were using third party library for Paypal payment but now Paypal provide us their own library for payment so it is now much secure and easy to implement in our application. Below are the important step to do -




1)First go through Paypal Developer web site and create an application.

2)Now open your manifest file and give the below permissions-

<uses-permission android:name="android.permission.INTERNET" />

     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />


3)And some required Activity and Services-

<service
            android:name="com.paypal.android.sdk.payments.PayPalService"
            android:exported="false" />

        <activity android:name="com.paypal.android.sdk.payments.PaymentActivity" />
        <activity android:name="com.paypal.android.sdk.payments.LoginActivity" />
        <activity android:name="com.paypal.android.sdk.payments.PaymentMethodActivity" />
        <activity android:name="com.paypal.android.sdk.payments.PaymentConfirmActivity" />
        <activity android:name="com.paypal.android.sdk.payments.PayPalFuturePaymentActivity" />
        <activity android:name="com.paypal.android.sdk.payments.FuturePaymentConsentActivity" />
        <activity android:name="com.paypal.android.sdk.payments.FuturePaymentInfoActivity" />
        <activity
            android:name="io.card.payment.CardIOActivity"
            android:configChanges="keyboardHidden|orientation" />
        <activity android:name="io.card.payment.DataEntryActivity" />


4)Open your Activity class and set Configuration for your app-
//set the environment for production/sandbox/no netowrk
       private static final String CONFIG_ENVIRONMENT = PayPalConfiguration.ENVIRONMENT_PRODUCTION;


5)Now set client id from the Paypal developer account-
     private static final String CONFIG_CLIENT_ID = "PUT YOUR CLIENT ID";


6)Inside onCreate method call the Paypal service-
Intent intent = new Intent(this, PayPalService.class);
        intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);
        startService(intent);


7)Now you are ready to make a payment just on button press call the Payment Activity-
PayPalPayment thingToBuy = new PayPalPayment(new BigDecimal(1),"USD", "androidhub4you.com",
                                 PayPalPayment.PAYMENT_INTENT_SALE);

                             Intent intent = new Intent(MainActivity.this, PaymentActivity.class);

                             intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);


                             startActivityForResult(intent, REQUEST_PAYPAL_PAYMENT);    


8)And finally from the onActivityResult get the payment response-
  @Override
           protected void onActivityResult(int requestCode, int resultCode, Intent data) {
               if (requestCode == REQUEST_PAYPAL_PAYMENT) {
                   if (resultCode == Activity.RESULT_OK) {
                       PaymentConfirmation confirm = data
                               .getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
                       if (confirm != null) {
                           try {
                           System.out.println("Responseeee"+confirm);
                               Log.i("paymentExample", confirm.toJSONObject().toString());

                            
                               JSONObject jsonObj=new JSONObject(confirm.toJSONObject().toString());
                              
                               String paymentId=jsonObj.getJSONObject("response").getString("id");
                               System.out.println("payment id:-=="+paymentId);
                               Toast.makeText(getApplicationContext(), paymentId, Toast.LENGTH_LONG).show(); 

                           } catch (JSONException e) {
                               Log.e("paymentExample", "an extremely unlikely failure occurred: ", e);
                           }
                       }
                   } else if (resultCode == Activity.RESULT_CANCELED) {
                       Log.i("paymentExample", "The user canceled.");
                   } else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID) {
                       Log.i("paymentExample", "An invalid Payment was submitted. Please see the docs.");
                   }
               }
              
               
         }




For any query or suggestion please post your feedback.

Thanks,

    1. you are using the Classic API Username instead of the application client_id. To fix, log in to developer.paypal.com, navigate to Applications > My Apps > the name of your app. Open the 'REST API CREDENTIALS ' window, and you'll see a sandbox and live client_id. Copy the appropriate id into your app.

    1. I think for security reason you can't. You need to make an app on Paypal account and only that account you can use for transaction.
