What is Camera2 API?

Camera 2 API was introduced by Google with the Android Version 5.

Before Camera 2 API, camera functions of any device was very limited. Camera app could just be used to preview and capture images and take a video. With Camera 2 API, Google gives camera developers options to do more with the camera. Control the shutter speed(ISO), focus, RAW capture etc.

How to check if Camera2 API is enabled at your phone

All you need to do is download a simple app called ‘Manual Camera Compatibility’ from the Google Play Store and run it.

1. Install the Manual Camera Compatibility app from the Play Store.

2. Open the app and click on the Start button to start the Camera2 API test.

3. The app will show you the camera2 API support, once the test is completed.

4. If it shows all features are supported, then you can just download the compatible GCam APK for your phone and install it.

5. If the Manual Camera Compatibility app reports that your device does not support manual settings, then you need to manually enable the Camera2 API.

Uses:

The most common and the only use for most of the people here would be to know whether or not Gcam can be used in their phone. If the phone has Camera2 API enabled, Gcam can be used else it cannot be used on the phone.

This helps third-party developers to include more features in their applications with the tools they are given through the API.
