    Reduce network battery drain. Most of the code will be written in this MainActivity, and all the functions will be implemented as easily as possible so that readers can focus only on the focus. It would be wise to have this handler instance instantiated with a thread of our choosing so we can delegate work to it. The next thing we need to do is call the CameraManager. Sharing files with NFC. I pulled out almost all functionalities that relate to Camera out side of Camera2BasicFragment. On the other, there is a way to customize your interaction with the camera.

    Camera2 is the latest Android camera framework API that replaces the deprecated camera framework libraries. Camera2 provides in-depth.There are a lot of other things you can do, like capturing a slow motion video, switching between the front and back cameras, controlling the focus, and much more.

    Learn Android - Camera2 APIs are available in API 21+ (Lollipop and beyond)Even if an Android device has a 21+ ROM officially, there is no guarantee that it.It can be said that CameraManager is the starting point of Camera2 usage process, so first we need to get an instance of CameraManager through getSystemService :.

    To reduce the difficulty of reading the source code, I do not intend to introduce any third-party libraries, focus on performance issues, or design in any mode.

    For most developers, we recommend you use the CameraX Jetpack library for a consistent and easy-to-use API surface that works across all Android devices starting from Android 5.
