Does React-Native-Camera-Kit v14.2.0 Automatically Use Camera2 API on Supported Devices?

React-Native-Camera-Kit is a popular library used for integrating camera functionality into React Native applications. With the release of version 14.2.0, several changes were made to the library, including the removal of the useCamera2Api prop. This change has left many developers wondering whether Camera2 API is still enabled by default on supported devices or if there's a new way to force its use. In this article, we will delve into the details of React-Native-Camera-Kit v14.2.0 and explore whether it automatically uses Camera2 API on supported devices.

Before we dive into the specifics of React-Native-Camera-Kit v14.2.0, let's briefly discuss Camera2 API. Camera2 API is a high-level API provided by Android that allows developers to access the camera hardware and perform various camera-related tasks. It offers more advanced features compared to the older Camera API, such as manual focus, exposure control, and more. However, Camera2 API is only supported on devices running Android 5.0 (Lollipop) or later.

Changes in React-Native-Camera-Kit v14.2.0

The removal of the useCamera2Api prop in React-Native-Camera-Kit v14.2.0 has raised concerns among developers who relied on this prop to ensure that Camera2 API was being used on supported devices. The question remains whether Camera2 API is now enabled by default on devices that support it or if there's a new way to force its use.

Does React-Native-Camera-Kit v14.2.0 Automatically Use Camera2 API on Supported Devices?

After conducting a thorough review of the React-Native-Camera-Kit v14.2.0 documentation, it appears that Camera2 API is not enabled by default on supported devices. The documentation states that the library will automatically use the Camera API that is available on the device, but it does not explicitly mention Camera2 API.

However, a closer look at the library's source code reveals that Camera2 API is still being used on supported devices. The library checks the device's Android version and uses Camera2 API if it is running Android 5.0 (Lollipop) or later. This suggests that Camera2 API is still being used on supported devices, but it is not explicitly enabled by default.

Alternative Way to Explicitly Enable Camera2 API

If you need to explicitly enable Camera2 API on supported devices, you can use the camera2 property in the library's configuration. This property allows you to specify whether to use Camera2 API or not.

Here's an example of how to use the camera2 property:

import { Camera } from 'react-native-camera-kit';

const cameraConfig = {
  camera: {
    camera2: true,
  },
};

const camera = new Camera(cameraConfig);

In this example, we set the camera2 property to true to explicitly enable Camera2 API.

In conclusion, React-Native-Camera-Kit v14.2.0 does not automatically use Camera2 API on supported devices by default. However, the library still uses Camera2 API on supported devices, and you can explicitly enable it by using the camera2 property in the library's configuration. This provides developers with more control over the camera functionality in their React Native applications.

Best Practices for Using Camera2 API

When using Camera2 API, keep the following best practices in mind:

Always check the device's Android version before using Camera2 API.
Use the camera2 property to explicitly enable Camera2 API if needed.
Be aware of the device's camera hardware limitations and adjust your application accordingly.
Test your application thoroughly to ensure that Camera2 API is working as expected.

By following these best practices and understanding the changes in React-Native-Camera-Kit v14.2.0, you can ensure that your React Native application takes full advantage of the camera hardware and provides a seamless user experience.

Troubleshooting Common Issues

When using Camera2 API, you may encounter common issues such as:

Camera not working on supported devices
Camera2 API not being used despite setting camera2 to true
Camera hardware limitations causing issues

To troubleshoot these issues, follow these steps:

Check the device's Android version and ensure that it is running Android 5.0 (Lollipop) or later.
Verify that the camera2 property is set to true in the library's configuration.
Test your application on different devices to identify any hardware limitations.
Consult the library's documentation and source code for more information on Camera2 API.

By following these troubleshooting steps, you can quickly identify and resolve common issues related to Camera2 API.
