Android API Level 23
Android API Level 23, also known as Android 6.0 (Marshmallow), is a specific version of the Android operating system's application programming interface (API) that defines the set of features, permissions, and capabilities available to developers. It introduced significant changes such as runtime permissions, Doze mode for battery optimization, and fingerprint authentication support. This API level serves as a target for app development, ensuring compatibility with devices running Android 6.0 and above.
Developers should learn and target API Level 23 when building apps that require modern Android features like runtime permissions for better user privacy control, or when optimizing for battery life with Doze mode. It is essential for apps that need to support fingerprint authentication or target devices running Android 6.0 and later, as it marks a key transition in Android's permission model and security enhancements.
