Creating Android Project

Adding PayPal Client ID

  • Create a new Android Project. I created PayPalIntegration.
  • In your package create a class named and write the following code.

  • In the above code you have to put your paypal client id. Now we need to add PayPal SDK to our project.

Adding PayPal SDK

  • We are using Android Studio so go inside your app level build.gradle file. (Someone said that he doesn’t understand app level build.gradle) So I am posting the screenshot. The highlighted one is app level build.gradle file and above that you have the project level build.gradle file. You need to open the app level build.gradle file.


  • Inside the app level build.gradle file you will see dependencies block. Inside that you need to add your paypal sdk. So add the following code.

Integrating Paypal Payment

  • You will get the following UI with the above given code.

  • Now come inside and declare objects for your views and add listener to the button.

  • Inside onCreate() initialize the views and add listener to the buttons.

  • Now create a method named getPayment() and call it on button click.

  • Now to get Payment from PayPal we need a PayPal Configuration Object and a Request Code.

  • Inside onCreate() method we need to start PayPalService.

  • We should destroy the service when app closes.

  • Now complete the method getPayment() with the following code.

  • The above method will invoke the onActivityResult() method after completion. So override onActivityResult() and write the following code.

  • In the above code you can see the string paymentDetails. It is in json format as follows. It contains the payment detail with a unique payment id.

  • In this post I am not covering the verification process. As you need to verify the payment at your server with the payment id you are seeing in the above json.
    You need to store the unique id at your server after the verification. In the next part we will cover the verification process at the server.
    In this tutorial we will show these details to another activity. 
  • Now we will create another activity where we will show the payment details. So create a new empty activity I created And inside layout file for this activity write the following xml code.

  • Now in the java file which is write the following code.

  • Thats it now just run your application and you will get the following output.
