Question

Android

Good afternoon. There is an Android application, which is, roughly speaking, an online store.
How to implement the function of paying for purchases with a card? Are there any payment systems for this?
ps I saw similar functionality in the AliExpress application.

Answer 1

Through webview and payment gateway of any bank. On API 16 and above, there should be no particular problems.
With PayPal it's easier, they have an SDK.
Just remember, through external services you can only pay for real goods. Otherwise they will be banned.
