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-

            android:exported="false" />

        <activity android:name="" />
        <activity android:name="" />
        <activity android:name="" />
        <activity android:name="" />
        <activity android:name="" />
        <activity android:name="" />
        <activity android:name="" />
            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);

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", "",

                             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-
           protected void onActivityResult(int requestCode, int resultCode, Intent data) {
               if (requestCode == REQUEST_PAYPAL_PAYMENT) {
                   if (resultCode == Activity.RESULT_OK) {
                       PaymentConfirmation confirm = data
                       if (confirm != null) {
                           try {
                               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.

  3. Hi Manish ...Thanks for ur awesome tutorials on uncommon & nice topics... This tutorial was great too. Please let me know if you have any prior experience with paypal...Do they accept indian cards? And ...Only these steps you mentioned are required to start online transactions.

    1. Indian cards means? well try this demo app it will accept all type of common card like Visa, Master etc.

  4. Can you check my code here
    i am getting invalid merchant clientId, Thanks

    1. you are using the Classic API Username instead of the application client_id. To fix, log in to, 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.

  5. Hi manish thanks for the above tutorial... and i have few queries... i have done all the above steps but my response remains same i.e pay ID and created_time... why so? and how will i know that the payment has happened? (will there be any mail sent or invoice to acknowledge my transfer) and i have already droped question in stack overflow regarding this( if you could help then it will be great thanks...
