In the Android phone, the best feature is a camera for capturing the picture and videos. And in the apps, we can take pictures and videos just by using default mobile camera app but sometime in the app, we need to add a camera functionality inside our app.
In Google IO 2019, Google added another powerful tool for camera development in Android development called CameraX as part of Jetpack.
CameraX is an addition to Jetpack that makes it easier to leverage the capabilities of Camera2 APIs. This topic covers the architecture of CameraX, including its structure, how to work with the API, how to work with Lifecycles, and how to combine use cases.
Steps to implement cameraX
1. Add the dependency in build.gradle file
2. We are using TextureView tag in order to display camera in a view. Please review the xml file here:-
3. Now, we have to add Camera permission in AndroidManifest file
And we also need to take runtime permission for all android version 6 and above.
4. Now we have to add the following code in the CameraActivity.kt file.
You can also review the more details about cameraX and its feature and enjoy in making more interesting functionality like dubsmash, edit picture in your android app. Please refer the following the link for more details:-
