Android Camera API
The Android Camera API is a set of classes and interfaces provided by the Android SDK that allows developers to capture photos and videos, control camera hardware, and process image data on Android devices. It provides low-level access to camera features such as autofocus, flash, exposure, and manual settings, enabling custom camera applications beyond the default system camera. The API supports both the legacy Camera API (deprecated in Android 5.0) and the newer Camera2 API (introduced in Android 5.0) for advanced camera control.
Developers should learn the Android Camera API when building custom camera apps, augmented reality features, or applications requiring specialized image capture, such as barcode scanners, document scanners, or photography tools. It is essential for scenarios where fine-grained control over camera parameters is needed, like adjusting shutter speed or ISO in manual mode, or when integrating real-time image processing. Use the Camera2 API for modern Android apps (API level 21+) to leverage advanced capabilities like burst capture and RAW image support.
