Implementing Google Pay on Android
Currently Google Pay cannot be used as a webview within Android apps. This is because pop-up blockers are built into the webviews, preventing Google Pay to be displayed. As a result, in order to allow your customers to purchase crypto using Google Pay, you will need to redirect the customer to the browser.
