PayPal Here Android App Cash Payment Declined

[StinkyHlavinka]

When I swipe or try a cash payment in the PayPal Here app I get a "Transaction Cancelled Unable to process payment" message. It then goes to a screen showing a big red "DECLINED" message. I'm sideloading the PayPal Here app from my Android app, sending it a JSON invoice object. It worked before, so I'm not sure what's going on now and I don't know where to get more details.

Got it. The "invoice number" I was passing it was incorrect, I guess. Once I stopped sending one, or sending one in that specific format, it allowed my transaction to go through. An integer invoice number must be the way to go.
