Google Pay Android SDK

Android SDK allows you to accept Google Pay payments from Android application.

The latest version of Android SDK you can always find in our public repository

https://github.com/cloudipsp/android-sdk

In the demo directory you can find an example of an application which implements Google Pay functionality

Also, you can refer the central Maven repository: https://search.maven.org/search?q=g:com.cloudipsp and use SDK as maven dependency as:

compile 'com.cloudipsp:android:+'

For complete examples of code in Activity.java or Kotlin, please scroll down.

1 Setup your application

Add dependencies to your project in app/build.gradle. This implementation requires Google Play services 17.0.0 or greater

implementation 'com.google.android.gms:play-services-base:17.0.0'
implementation 'com.google.android.gms:play-services-wallet:19.4.0'
implementation 'com.cloudipsp:android:+'

2 Update AndroidManifest.xml to enable Google Pay API.

Add the following lines:

<uses-permission android:name="android.permission.INTERNET" />
<meta-data
    android:name="com.google.android.gms.wallet.api.enabled"
    android:value="true"
>
For more information please follow Google Pay API setup instruction

3 Setup your MearchantId

Create an instance of Cloudipsp with your MerchantID identifier from Flitt Merchant Portal

cloudipsp = new Cloudipsp(<your merchant_id>, webView);

4 Create Google Pay button in your application layout 

<Button
    android:id="@+id/google_pay_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Pay with Google Pay" />

And add CloudIpspdWebView Component 

<com.cloudipsp.android.CloudipspWebView
    android:id="@+id/webView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:visibility="gone" 
/>

5 Implement the Activity.java file as follows: 

import com.cloudipsp.android.Cloudipsp

Public class MainActivity extends AppCompatActivity implements
        View.OnClickListener, // Implementing OnClickListener for handling button clicks
        Cloudipsp.PayCallback, // Implementing Cloudipsp.PayCallback for payment callbacks
        Cloudipsp.GooglePayCallback { // Implementing Cloudipsp.GooglePayCallback for Google Pay callbacks

}

6 Make sure that Google Pay is supported on the device and user account

googlePayButton = findViewById(R.id.google_pay_button); // Initialize Button from layout

// Check if Google Pay is supported and set button visibility accordingly
if (Cloudipsp.supportsGooglePay(this)) {
    googlePayButton.setVisibility(View.VISIBLE); // Show Google Pay button
} else {
    googlePayButton.setVisibility(View.GONE); // Hide Google Pay button if unsupported
    Toast.makeText(this, R.string.e_google_pay_unsupported, Toast.LENGTH_LONG).show(); // Show unsupported message
}

7 Initiate payment on backend and obtain payment token

Create order at your server:

curl -i -X POST \
 -H "Content-Type:application/json" \
 -d \
'{
  "request": {
    "server_callback_url": "http://myshop/callback/",
    "order_id": "TestOrder_JSSDK_v2",
    "currency": "GEL",
    "merchant_id": 1549901,
    "order_desc": "Test payment",
    "lifetime" : 999999,
    "amount": 1000,
    "signature": "91ea7da493a8367410fe3d7f877fb5e0ed666490"
  }
}' \
 'https://pay.flitt.com/api/checkout/token'

Receive payment token:

{
  "response":{
    "response_status":"success",
    "token":"b3c178ad84446ef36eaab365b1e12e6987e9b3d9"
  }
}

8 Add click listener on Google Pay button 

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); // Set the layout for this activity

    // Initialize UI elements
    webView = findViewById(R.id.webView); // Initialize CloudipspWebView from layout
    googlePayButton = findViewById(R.id.google_pay_button); // Initialize Button from layout

    googlePayButton.setOnClickListener(this); // Set click listener for Google Pay button

    if (Cloudipsp.supportsGooglePay(this)) {
        googlePayButton.setVisibility(View.VISIBLE); 
    } else {
        googlePayButton.setVisibility(View.GONE); 
        Toast.makeText(this, R.string.e_google_pay_unsupported, Toast.LENGTH_LONG).show();
    }
}

@Override
public void onClick(View v) {
    if (v.getId() == R.id.google_pay_button) {
        processGooglePay(); 
    }
}

9 Process googlePay

Declare and initialize CloudipspWebView

private CloudipspWebView webView;

Initialize CloudipspWebView from Layout

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); 

    webView = findViewById(R.id.webView); // Initialize CloudipspWebView 

}

Initialize Cloudipsp with 0 merchant ID and WebView (token instead of merchant ID will be taken from step 7)

private void processGooglePay() {
    cloudipsp = new Cloudipsp(0, webView);
}

Handle Google Pay initialization if needed

@Override
public void onGooglePayInitialized(GooglePayCall result) {
    Toast.makeText(this, "Google Pay initialized", Toast.LENGTH_LONG).show(); // Show Google Pay initialization message
    this.googlePayCall = result; // Store Google Pay call result
}

Initiate the payment process, call method – googlePayInitialize with token

if (Cloudipsp.supportsGooglePay(context)) {
    cloudipsp?.googlePayInitialize(
        paymentToken,
        context.findActivity(),
        MainActivity.RC_GOOGLE_PAY,
        googlePayCallback
    )
}

cloudipsp.googlePayInitialize get 4 params : paymentToken , activity , request code And Google Pay callback

WebView 3DSecure confirmation

After initiating the payment process, the configured 3DS WebView will open. In test mode, it should look like this :

Handle payment failure

@Override
public void onPaidFailure(Cloudipsp.Exception e) {
    if (e instanceof Cloudipsp.Exception.Failure) {
        Cloudipsp.Exception.Failure f = (Cloudipsp.Exception.Failure) e;
        Toast.makeText(this, "Failure\nErrorCode: " +
                f.errorCode + "\nMessage: " + f.getMessage() + "\nRequestId: " + f.requestId, Toast.LENGTH_LONG).show(); // Show specific failure details
    } else if (e instanceof Cloudipsp.Exception.NetworkSecurity) {
        Toast.makeText(this, "Network security error: " + e.getMessage(), Toast.LENGTH_LONG).show(); // Show network security error
    } else if (e instanceof Cloudipsp.Exception.ServerInternalError) {
        Toast.makeText(this, "Internal server error: " + e.getMessage(), Toast.LENGTH_LONG).show(); // Show internal server error
    } else if (e instanceof Cloudipsp.Exception.NetworkAccess) {
        Toast.makeText(this, "Network error", Toast.LENGTH_LONG).show(); // Show network access error
    } else {
        Toast.makeText(this, "Payment Failed", Toast.LENGTH_LONG).show(); // Show generic payment failure
    }
    e.printStackTrace(); // Print stack trace for debugging
}

10 Complete payment

Pass the result from onActivityResult to the SDK.

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case RC_GOOGLE_PAY:
            if (!cloudipsp.googlePayComplete(resultCode, data, googlePayCall, this)) {
                Toast.makeText(this, R.string.e_google_pay_canceled, Toast.LENGTH_LONG).show(); // Show payment canceled message
            }
            break;
    }
}

Handle Result of payment 

@Override
public void onPaidProcessed(Receipt receipt) {
    Toast.makeText(this, "Paid " + receipt.status.name() + "\nPaymentId:" + receipt.paymentId, Toast.LENGTH_LONG).show(); // Show payment success message
}

Handle back navigation 

@Override
public void onBackPressed() {
    if (webView.waitingForConfirm()) {
        webView.skipConfirm(); // Skip confirmation in WebView if waiting
    } else {
        super.onBackPressed(); // Otherwise, perform default back button behavior
    }
}

If your activity is destroyed and recreated (e.g., due to a screen rotation), onSaveInstanceState() ensures that googlePayCall, which is presumably a critical object related to payment processing, is saved (putParcelable()) and restored (onRestoreInstanceState()) properly.

private GooglePayCall googlePayCall; // <- this should be serialized on saving instance state

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); // Set the layout for this activity

    if (savedInstanceState != null) {
        googlePayCall = savedInstanceState.getParcelable(K_GOOGLE_PAY_CALL);
    }
}

Save instance

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putParcelable(K_GOOGLE_PAY_CALL, googlePayCall);
}
