Overview of Android SDK
The Zettle Payments SDK for Android lets your merchants take payments from an Android app, using a Zettle card reader or QRC.
The SDK is compatible with apps supporting Android API level 21 and above. The SDK itself is written in Kotlin which is the preferred language. However, examples are available both in Kotlin and Java.
Currently, SDK offers 2 payment methods : Card payments, and QRC using PayPal or Venmo.
