IPay88 Payment Gateway into Android

In this article, we are going to learn how we can integrate the IPay88 payment gateway into android.

We are going to do this step by step

1. First, you need to download the .jar or .aar file of the SDK. Download the IPay88 SDK from this link.

2. Once downloaded you need to place the SDK in the libs folder and update your app level gradle file to read the SDK.

api fileTree(include: ['*.aar', '*.jar'], dir: 'libs')

1	api fileTree(include: ['.aar', '.jar'], dir: 'libs')

3. Now we need to initialize the payment.

private fun initPayment(data: IPay88Data): IPayIHPayment {
        return IPayIHPayment().apply {
            responseURL =
                data.responseUrl // replace this with the response URL that comes from server
            backendPostURL = data.postUrl // replace this with server's post url
            country = data.country
            merchantKey = data.merchantKey
            merchantCode = data.merchantCode
            paymentId = data.paymentId
            refNo = data.refNo
            amount = data.amount
            currency = data.currency
            prodDesc = data.productDescription
            userName = data.username
            userEmail = data.userEmail
            userContact = data.userContact
            remark = data.remark
            lang = data.language
        }
    }

private fun initPayment(data: IPay88Data): IPayIHPayment {

return IPayIHPayment().apply {

responseURL =

data.responseUrl // replace this with the response URL that comes from server

backendPostURL = data.postUrl // replace this with server's post url

country = data.country

merchantKey = data.merchantKey

merchantCode = data.merchantCode

paymentId = data.paymentId

refNo = data.refNo

amount = data.amount

currency = data.currency

prodDesc = data.productDescription

userName = data.username

userEmail = data.userEmail

userContact = data.userContact

remark = data.remark

lang = data.language

}

IPay88Data.kt class

class IPay88Data(
    var responseUrl: String,
    var postUrl: String,
    var country: String,
    var merchantKey: String,
    var merchantCode: String,
    var paymentId: String,
    var refNo: String,
    var amount: String,
    var currency: String,
    var productDescription: String,
    var username: String,
    var userEmail: String,
    var userContact: String,
    var remark: String,
    var language: String
)

class IPay88Data(

var responseUrl: String,

var postUrl: String,

var country: String,

var merchantKey: String,

var merchantCode: String,

var paymentId: String,

var refNo: String,

var amount: String,

var currency: String,

var productDescription: String,

var username: String,

var userEmail: String,

var userContact: String,

var remark: String,

var language: String

)

Now we need to instantiate the payment process.

// code ...

val intent = IPayIH.getInstance()
                .checkout(payment, this, ResultDelegate(), IPayIH.PAY_METHOD_CREDIT_CARD)

startActivityForResult(intent, PAYMENNT_CODE)

// code ...

// code ...

val intent = IPayIH.getInstance()

.checkout(payment, this, ResultDelegate(), IPayIH.PAY_METHOD_CREDIT_CARD)

startActivityForResult(intent, PAYMENNT_CODE)

// code ...

Here ResultDelegate class is responsible for the result (i.e success, failed, cancelled etc)

ResultDelegate.kt class

class ResultDelegate : IPayIHResultDelegate, Serializable {
    override fun onPaymentSucceeded(
        transactionId: String?,
        p1: String?,
        p2: String?,
        p3: String?,
        p4: String?,
        p5: String?,
        p6: String?,
        p7: String?,
        p8: String?
    ) {
        MainActivity.paymentSuccess = true

        Log.i(TAG, "onPaymentSucceeded")
    }

    override fun onPaymentFailed(
        transactionId: String?,
        p1: String?,
        p2: String?,
        p3: String?,
        p4: String?,
        p5: String?,
        p6: String?,
        p7: String?,
        p8: String?
    ) {
        MainActivity.paymentFailed = true
        Log.i(TAG, "onPaymentFailed: ")
    }

    override fun onPaymentCanceled(
        transactionId: String?,
        p1: String?,
        p2: String?,
        p3: String?,
        p4: String?,
        p5: String?,
        p6: String?,
        p7: String?,
        p8: String?
    ) {
        MainActivity.paymentCancelled = true
        Log.i(TAG, "onPaymentCanceled: ")
    }

    override fun onRequeryResult(p0: String?, p1: String?, p2: String?, p3: String?) {
        Log.i(TAG, "onRequeryResult: ")
    }

    override fun onConnectionError(
        p0: String?,
        p1: String?,
        p2: String?,
        p3: String?,
        p4: String?,
        p5: String?,
        p6: String?
    ) {
        Log.i(TAG, "onConnectionError: ")
    }

    companion object {
        private const val TAG = "ResultDelegate"
    }
}

class ResultDelegate : IPayIHResultDelegate, Serializable {

override fun onPaymentSucceeded(

transactionId: String?,

p1: String?,

p2: String?,

p3: String?,

p4: String?,

p5: String?,

p6: String?,

p7: String?,

p8: String?

) {

MainActivity.paymentSuccess = true

Log.i(TAG, "onPaymentSucceeded")

}

override fun onPaymentFailed(

transactionId: String?,

p1: String?,

p2: String?,

p3: String?,

p4: String?,

p5: String?,

p6: String?,

p7: String?,

p8: String?

) {

MainActivity.paymentFailed = true

Log.i(TAG, "onPaymentFailed: ")

}

override fun onPaymentCanceled(

transactionId: String?,

p1: String?,

p2: String?,

p3: String?,

p4: String?,

p5: String?,

p6: String?,

p7: String?,

p8: String?

) {

MainActivity.paymentCancelled = true

Log.i(TAG, "onPaymentCanceled: ")

}

override fun onRequeryResult(p0: String?, p1: String?, p2: String?, p3: String?) {

Log.i(TAG, "onRequeryResult: ")

}

override fun onConnectionError(

p0: String?,

p1: String?,

p2: String?,

p3: String?,

p4: String?,

p5: String?,

p6: String?

) {

Log.i(TAG, "onConnectionError: ")

}

companion object {

private const val TAG = "ResultDelegate"

}

Create static variables to keep track of the result state i.e success, failed, canceled etc.

// Static members to keep track of different cases
@JvmField
var paymentSuccess = false

@JvmField
var paymentFailed = false

@JvmField
var paymentCancelled = false

// Static members to keep track of different cases

@JvmField

var paymentSuccess = false

@JvmField

var paymentFailed = false

@JvmField

var paymentCancelled = false

4. We also need to declare the IPayActivity in the manifest as well.

Add the following line in your Manifest file under the application tag.

<activity
    android:name="com.ipay.IPayIHActivity"
    android:configChanges="orientation|screenSize" />

<activity

android:name="com.ipay.IPayIHActivity"

android:configChanges="orientation|screenSize" />

Note: If you have declared minSdk to 21 then you might get the following error.

To fix the above issue add this line in your Manifest file under the application tag

<uses-library
    android:name="org.apache.http.legacy"
    android:required="false" />

<uses-library

android:name="org.apache.http.legacy"

android:required="false" />

5. Once your payment is initiated you should see a screen like this.

6. Finally manage the different cases using static variables that we have created earlier.
