If you are interested in Paymob payment and want Paymob payment gateway integration in android with SDK then this blog will help you to do so.

Paymob payment gateway work on the below steps:

Implementation

1. Initial setup

Download the SDK from the link.

Add the .aar files in the lib folder.

2. Initialize payment

SDK PaymentForm provides the UI interface for payment. So you have to create or initialize the view.

We are using the Paymob PayActivity that will contain the UI for payment. So we have to start the Activity for result like:

val pay_intent = Intent(mFragmentContext.context, PayActivity::class.java)
pay_intent.putExtra(PayActivityIntentKeys.PAYMENT_KEY, "Payment key")
pay_intent.putExtra(PayActivityIntentKeys.THREE_D_SECURE_ACTIVITY_TITLE, "Verification")
pay_intent.putExtra(PayActivityIntentKeys.SAVE_CARD_DEFAULT, false)
pay_intent.putExtra(PayActivityIntentKeys.SHOW_SAVE_CARD, false)
pay_intent.putExtra(PayActivityIntentKeys.THEME_COLOR, mFragmentContext.requireContext().getResources().getColor(R.color.colorPrimary))
pay_intent.putExtra("ActionBar", true)
pay_intent.putExtra("language", "en")
mFragmentContext.startActivityForResult(pay_intent, RC_PAYMOB_REQUEST)
val secure_intent = Intent(mFragmentContext.context, ThreeDSecureWebViewActivty::class.java)
secure_intent.putExtra("ActionBar", true)

val pay_intent = Intent(mFragmentContext.context, PayActivity::class.java)

pay_intent.putExtra(PayActivityIntentKeys.PAYMENT_KEY, "Payment key")

pay_intent.putExtra(PayActivityIntentKeys.THREE_D_SECURE_ACTIVITY_TITLE, "Verification")

pay_intent.putExtra(PayActivityIntentKeys.SAVE_CARD_DEFAULT, false)

pay_intent.putExtra(PayActivityIntentKeys.SHOW_SAVE_CARD, false)

pay_intent.putExtra(PayActivityIntentKeys.THEME_COLOR, mFragmentContext.requireContext().getResources().getColor(R.color.colorPrimary))

pay_intent.putExtra("ActionBar", true)

pay_intent.putExtra("language", "en")

mFragmentContext.startActivityForResult(pay_intent, RC_PAYMOB_REQUEST)

val secure_intent = Intent(mFragmentContext.context, ThreeDSecureWebViewActivty::class.java)

secure_intent.putExtra("ActionBar", true)

Payment key is the the token generated from the server end. For more details please follow the link.

3. Handling payment callback:

It’s time to handle the payment callback. ThreeDSecureWebViewActivty() of payment, SDK is responsible for return callback to your app. Now, you have to get the data from the intent like :

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == ConstantsHelper.RC_PAYMOB_REQUEST) {
            if (resultCode == IntentConstants.USER_CANCELED) {
                //User canceled
            } else if (resultCode == IntentConstants.MISSING_ARGUMENT) {
                //Missing the key arguments
            } else if (resultCode == IntentConstants.TRANSACTION_ERROR) {
                //Tansaction error
            } else if (resultCode == IntentConstants.TRANSACTION_REJECTED) {
                //Transaction rejected 
            } else if (resultCode == IntentConstants.TRANSACTION_SUCCESSFUL) {
                //Payment success perform the next action
            }
        } 
    }

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

super.onActivityResult(requestCode, resultCode, data)

if (requestCode == ConstantsHelper.RC_PAYMOB_REQUEST) {

if (resultCode == IntentConstants.USER_CANCELED) {

//User canceled

} else if (resultCode == IntentConstants.MISSING_ARGUMENT) {

//Missing the key arguments

} else if (resultCode == IntentConstants.TRANSACTION_ERROR) {

//Tansaction error

} else if (resultCode == IntentConstants.TRANSACTION_REJECTED) {

//Transaction rejected

} else if (resultCode == IntentConstants.TRANSACTION_SUCCESSFUL) {

//Payment success perform the next action

}
