Paypal Redirect URI problem

[shobaky]

I am trying to integrate paypal checkout button with my android app, i have followed the official guide but it doesn't seem to work, when i click the button, it logs in taking the permissions but then it gives me a page saying "Returning to (application name)" with no progress!!

This is the returning URI in my developer console 

   com.example.myapplication://paypalpay

This is the returning URI in my application code

  com.example.myapplication://paypalpay

The configuration code

val config = CheckoutConfig(
    application = this,
    clientId = YOUR_CLIENT_ID,
    environment = Environment.SANDBOX,
    returnUrl = "com.example.myapplication://paypalpay",
    currencyCode = CurrencyCode.USD,
userAction = UserAction.PAY_NOW,
settingsConfig = SettingsConfig(
    loggingEnabled = true
)
)
PayPalCheckout.setConfig(config)
