Overview of Android SDK
The Zettle payment SDK for Android lets you accept 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 in Java.
