Hello,
I have my own Android application with Square point-of-sale sdk integrated. When a payment is required, our application uses the sdk method to call the Square app to process the payment.
This process works fine if we just started our application. However, if the application has been kept running for a a couple days, the Square callback scheme doesn’t work any more. That is, regardless of onTransaction success or failed in the Square pop-up, it doesn’t call the callback function in my app.
Having been struggling in this issue for a long time. Really appreciate if anyone could help out!
