Hi
Could you please share more details about your integration? what terminal integration are you following exactly ?

feral sphinx
#

hello, I'm trying to test Tap to pay on Android phone samsung galaxy S9 and I'm using

#

those packages:

// Stripe Terminal library
implementation "com.stripe:stripeterminal-localmobile:2.20.0"
implementation "com.stripe:stripeterminal-core:2.20.0"
jagged shuttle
#

You are getting this execption in which step ?

#

You are getting this failure, when proceeding a contactless payment transaction?

feral sphinx
#

in this method

#

private val collectPaymentMethodCallback by lazy {
object : PaymentIntentCallback {
override fun onSuccess(paymentIntent: PaymentIntent) {
Terminal.getInstance().processPayment(paymentIntent, processPaymentCallback)
}

        override fun onFailure(e: TerminalException) {
            e.printStackTrace()
        }
    }
}
#

once I type the amonut and then the app should show the tap the card screen, but the app crash because of the onFailure method

on this step:

Collect payments with Tap to Pay on Android

When your application is ready to collect a payment, the Stripe Android SDK takes over the display to handle the collection process. After calling the collect payment method, your application remains running. The Android device displays a full-screen prompt to the cardholder, instructing them to present their card or NFC-based mobile wallet. If there’s an error reading the card, a prompt for retry displays. A successful presentation returns a success indication, and then control returns to your application to process the payment.

Ok according to the error message, it's a connectivity/network issue:

#

Could you try inspect the network/connectivity of that device?

feral sphinx
#

the netwrok is working, because I can connect ty my store location and get the lcation id as well a PaymentIntent

jagged shuttle
#

Ok let me do a quick test...

feral sphinx
#

this is the code I'm using for testing

#

the function I send before it's on 243 in MainActivity.kt

#

and this backend:

stripe/example-terminal-backend running on Render

jagged shuttle
#

So far, I'm not able to reproduce... trying to do more tests..

#

There must be something in your network that is blocking some request to AIDL server

#

Try another network

#

or another device.

feral sphinx
#

ok, i'll test withother device
