JarCastingPayPal IAP for Android
An unofficial PayPal In-App-Purchase library for Android apps. Using this you can easily accept payments within your Android app.
The library source is hidden to protect it from anti-tampering.
If you are likely publishing your app to Google Play. It is recommended not to use any other payment method other than their official one. There is a high chance your app might get banned.
It is always good to have other IAP methods.

FAQ
Q. How is this different from the offical?
Well, for starters the official sdk repository has no long term support but its ok since it still works. The main problem with direct payments are, they don't return purchase details as this library does.
Also it doesn't accept credit card purchase which is possible by using PayPal buttons. XDA Labs uses their own implementation of such process.
Q. Can you steal our credentials?
If you are thinking that I might steal your credential during payment process, then I must say this is technically not possible with only having "Internet" permission in manifest (also I don't care).

Usage
For more information on how to use this payment mode, check the sample provided in this Github repo. A basic workflow is shown below.
- Each IAP is basically a Paypal button, so you first need to create it by following this guide.
Checkout (Single payment only)
- You will need a
button Id&redirect urlwhich you have created in above step. Create anOptionsfromOptions.Builderclass with this information.
val options = Paypal.Options(
paypalButtonId = "button-id",
purchaseCompleteUrl = "redirect-url",
isSandbox = true // Set this to false to accept live payments
)
- Initialize
PayPalclass usingPayPal.Builderclass where you need to pass thisoptionas constructor parameter. This class will be responsible for payment checkout.
Note: Each instance of PayPal class can hold one button Id only.
private lateinit var paypal: Paypal
paypal = Paypal.Builder(options)
.setCallingContext(this) // Activity or Fragment
- Start your checkout process.
paypal.checkout(
closeOnCheckout = false, // See this parameter behavior at the bottom of this guide.
onCheckOutComplete = { details ->
Toast.makeText(this, "Completed with ${details?.email}", Toast.LENGTH_SHORT).show()
},
showCloseDialog = true, // (Optional) default true
showDoNotCloseInfo = true, // (Optional) default true
showProgressBar = true // (Optional) default true
)
Detect completion or cancellation
- You need to override
onActivityResultmethod as follows.
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (paypal.isPurchaseComplete(requestCode, resultCode)) {
val details = data?.getSerializableExtra(Paypal.PURCHASE_DATA) as? Paypal.History
// Do something after purchase complete.
// ...
} else if (paypal.isPurchaseCancelled(requestCode, resultCode)) {
// Do something after purchase cancelled.
}
}
Anatomy of closeOnCheckout
closeOnCheckout = false |
closeOnCheckout = true |
|---|---|
| You need to manually click "Return to Merchant" button to trigger purchase complete. | Directly exit payment screen after completing checkout. |
