You can find a converter in Google’s camera samples repo. You may need to convert it to a RGB bitmap if you need to perform other operations. You can set setOutputImageRotationEnabled to rotate the image to match the camera preview. It is rotated based on device rotation for camera preview while the ImageProxy gives the raw image. The camera sensor’s natural orientation is landscape.The resolution can also be set using setTargetAspectRatio. The Size should match the screen orientation. The resolution is set using setTargetResolution.Preview and ImageAnalysis should share the same target resolution.Set event listener for the open camera protected void onCreate ( Bundle savedInstanceState ) Use CameraX to Preview and Analyse Images A Button is used to open the camera activity.Ĭreate a new activity named CameraActivity to show camera preview and barcode reading results. Here is the content of activity_main.xml which defines the layout of the MainActivity. Add Dynamsoft Barcode Reader by following this guide.

In this article, we will talk about how to build a barcode scanner with CameraX as shown below. We don’t have to worry about concurrency as CameraX takes care of this for us. Image analysis is designed to facilitate using technologies like ML Kit to analyse buffered images, which is also useful for barcode reading.

These features reduce the amount of code you need to write when adding camera capabilities to your app.ĬameraX has three basic use cases: preview, image analysis and image capture. It also resolves device compatibility issues for you so that you don’t have to include device-specific code in your code base. While CameraX leverages the capabilities of camera2, it uses a simpler approach that is lifecycle-aware and is based on use cases. It provides a consistent and easy-to-use API surface that works across most Android devices, with backward-compatibility to Android 5.0 (API level 21).
Here is the description from Google 2:ĬameraX is a Jetpack support library, built to help you make camera app development easier. 1 Its usage is complex (The two are compared in a previous post).ĬameraX is a newer one. Camera2 provides in-depth controls for complex use cases but requires you to manage device-specific configurations. In Android, there are three sets of Camera APIs to use: Camera, Camera2 and CameraX.Ĭamera can take photos and record videos. Making a good camera app, however, is not easy.
