Open Recipe
* * *
### 1\. Install PortOne Android SDK and Authorise it. [Skip link to 1. Install PortOne Android SDK and Authorise it.](https://docs.portone.cloud/docs/android-embed\#1-install-portone-android-sdk-and-authorise-it)
To begin, add the PortOne Android SDK to your project by adding the dependency to your build.gradle file.
- In the `build.gradle` (:app) file, add:
Kotlin
```rdmd-code lang-kotlin theme-light
implementation 'com.github.iamport-intl:portone-android-native-sdk:V3.0.48'
```
- Next, add the authKey to your `gradle.properties` file:.
Kotlin
```rdmd-code lang-kotlin theme-light
authKey= XXXXXXXXXXXXXXXXXXXXXX
```
- Authorize the SDK by adding the provided authKey to your `gradle.properties` file, which you can request by emailing the PortOne team at [in.dev@portone.io](mailto:in.dev@portone.io).
Then, configure your `build.gradle` (:Project) or `settings.gradle` to reference the key:
1. **`Build.gradle` (:Project) Setup:**
Kotlin
```rdmd-code lang-kotlin theme-light
repositories {
maven { url '<https://maven.google.com/>' }
maven{
url '<https://jitpack.io>'
credentials { username authKey }
}
}
```
2. **`Settings.gradle` Setup:**
Kotlin
```rdmd-code lang-kotlin theme-light
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
maven {
url 'https://maven.google.com/'
}
maven {
url 'https://jitpack.io'
credentials { username authKey } // Add your generated authKey here
}
}
}
```
Include the necessary code in your `build.gradle ()` file, specifying the project dependency and Kotlin version.
Kotlin
```rdmd-code lang-kotlin theme-light
buildscript {
ext.kotlin_version = "1.5.10" // Specify the Kotlin version here
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.2.2" // Add the Android Gradle plugin version
// Add any other dependencies needed for your project setup
}
}
```
### 2\. Set the Intent Filters in the Manifests [Skip link to 2. Set the Intent Filters in the Manifests](https://docs.portone.cloud/docs/android-embed\#2-set-the-intent-filters-in-the-manifests)
- Next, you need to add intent filters in your `AndroidManifest.xml` to handle payment status updates and navigate users back to your app after payment.
XML
```rdmd-code lang-xml theme-light
<activity android:name=".CheckoutActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="portone"
android:host="checkout" />
</intent-filter>
</activity>
```
This setup ensures your app can handle the redirection URL after payment completion. For detailed instructions, refer to the deep linking guide [here](https://developer.android.com/training/app-links/deep-linking).
### 3\. Set Intent Receivers for Payment Status: [Skip link to 3. Set Intent Receivers for Payment Status:](https://docs.portone.cloud/docs/android-embed\#3-set-intent-receivers-for-payment-status)
You’ll need to handle the payment status response using the `onActivityResult` method. Here’s an example:.
Kotlin
```rdmd-code lang-kotlin theme-light
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == RESULT_CODE && data != null) {
when (requestCode) {
PAYOUT_REQUEST_CODE, PAYMENT_STATUS_REQUEST_CODE -> {
val paymentStatus: CheckoutConnectDto.UpdatedPaymentStatusResponse? =
(data.getSerializableExtra(PAYMENT_STATUS)
?: "Empty") as CheckoutConnectDto.UpdatedPaymentStatusResponse
}
}
}
}
```
This method receives the payment status and updates the user interface with the payment result.
### 4\. Have a setup to get JWT token from the server [Skip link to 4. Have a setup to get JWT token from the server](https://docs.portone.cloud/docs/android-embed\#4-have-a-setup-to-get-jwt-token-from-the-server)
The PortOne SDK requires a JWT token for authentication. You need to implement a server-side process to generate this token and retrieve it in your Android app.
**Steps:**
1. Implement server logic to generate a JWT token.
2. In your Android app, fetch the token to process the checkout.
The process for generating a JWT token can be found in detail [here](https://docs-v2.portone.cloud/docs/jwt-authentication)
### 5\. Generate Signture Hash [Skip link to 5. Generate Signture Hash](https://docs.portone.cloud/docs/android-embed\#5-generate-signture-hash)
To generate a signature hash, create it on the server side using a secret key that will be included in the payload. This ensures secure processing of transactions.
> **Note**: Generating a signature hash is optional if you have whitelisted your app while initializing the checkout. Detailed instructions on this are provided in the checkout setup section.
**Steps:**
1. Implement server logic to generate a signature hash.
2. In your Android app, fetch the signature hash to process the checkout.
The process for generating a Signature Hash can be found in detail [here](https://docs-v2.portone.cloud/docs/payment-request)

## Initialization [Skip link to Initialization](https://docs.portone.cloud/docs/android-embed\#initialization)
To begin using the PortOne SDK, initialize the PortOne SDK instance in your activity. Set the environment to either `"sandbox"` for testing or `"live"` for production.
Kotlin
```rdmd-code lang-kotlin theme-light
portOne = PortOneImpl(
context = this,
environment = RequestBodies.environment,
applicationId = BuildConfig.APPLICATION_ID)
```
Parameters:
- `context`: The activity context where the SDK is being initialized.
- `environment`: Defines the environment in which the SDK operates.
- `"sandbox"` for testing
- `"live"` for production
- `applicationId`: (Optional) The unique ID of your application.
> **Note**: The `applicationId` parameter is required if the merchant wants to whitelist the app. When an app is whitelisted, the signature hash generation becomes optional, as the app is pre-authorized to securely process payments without it.
* * *
## Update Payment Status [Skip link to Update Payment Status](https://docs.portone.cloud/docs/android-embed\#update-payment-status)
As part of the setup for app-to-app flow, a deep link is configured to handle the transaction response. When the payment process completes, the app receives an intent with payment status data. It’s essential to check if this intent is available, and if so, pass its content to the SDK to update the transaction status.
Kotlin
```rdmd-code lang-kotlin theme-light
if (null != intent && null != intent.data) {
val paymentStatus = intent.data.toString()
portOne.updatePaymentStatus(paymentStatus)
}
```
> **Note**:This step is crucial for completing the transaction in the app-to-app flow, as it synchronizes the payment status with the server.
* * *
## Implementation [Skip link to Implementation](https://docs.portone.cloud/docs/android-embed\#implementation)
This is the method that has been utilised to process the web checkout.
Kotlin
```rdmd-code lang-kotlin theme-light

### **Response:** [Skip link to [object Object]](https://docs.portone.cloud/docs/android-embed\#response)
Receiving the payment status within the override method `onActivityResult` is a common practice in integration to handle payment callbacks. By implementing this method during the integration process, developers can capture and process the payment status information returned by the payment gateway or SDK. This allows for real-time feedback on the payment's success or failure, enabling further actions to be taken based on the outcome of the transaction.
