Common mistakes when working with CameraX?

CameraX is a powerful library in Android for managing camera functionalities. However, developers often encounter common pitfalls while integrating it into their applications. Here are some mistakes to avoid:

1. Not Handling Permissions Correctly

Failing to request runtime permissions can lead to app crashes or unexpected behaviors. Always ensure you have the proper camera permissions in your AndroidManifest.xml file and handle runtime permissions appropriately.

2. Ignoring Lifecycle States

CameraX is lifecycle-aware. Not properly binding it to the correct lifecycle can cause issues such as camera preview not starting or stopping unexpectedly. Make sure to bind the UseCases to the lifecycle of your activity or fragment.

3. Using Incompatible Devices

CameraX is designed to work across a variety of devices. However, always check whether a device supports specific features you wish to utilize. Ignoring device compatibility may result in crashes or features not behaving as expected.

4. Incorrectly Configuring UseCases

Improper configuration of UseCases like Preview, ImageCapture, and ImageAnalysis can lead to performance issues. Ensure you are using the correct settings and formats for your requirements.

5. Not Handling Image Processing on Background Threads

Image processing, such as converting an image or analyzing frames, should always be offloaded to a background thread. Doing this on the main thread can cause UI freezes and a poor user experience.

6. Overlooking Camera Rotation

When capturing images, not accounting for device rotation can lead to improperly oriented photos. Always set the correct orientation for your captured images according to device orientation.
