I am making a simple camera application using new Jetpack library CameraX. As soon as I launch the application just by adding dependencies it is crashing.
Dependencies:
implementation "androidx.camera:camera-core:1.0.0-alpha06"
implementation "androidx.camera:camera-camera2:1.0.0-alpha06"
Crash Logs:

Above scenario is the most common scenario when CLassNotFoundException is raised. However, it can become bit ugly or messy sometimes in a complex web deployment environments. Suppose your application is deployed as an EAR and it contains multiple jar and WAR files, it can sometimes raise this exception because of class visibility issues.
Sometimes accidentally the generated class files might be lost or set in different locations and hence there are a lot of chances of “ClassNotFoundException” occurs. After the existence of editors like Eclipse, Netbeans, etc., IDE creates a “ClassPath” file kind of entries.
Following simple steps will show you how to implement this app easily with details. To add dependency on camera X you must add the Google maven repository to your project in build.gradle. Add the following to end of the Android block. dependencies { …
In this tutorial will be looking into Android camera X architecture with basic camera example using Java language and Android IDE. Camera X is jetpack support library used to leverage the capabilities of camera 2 API built to help you make camera based app development easier.
ERROR:
// CameraX
def camerax_version = "1.0.0-beta07"
implementation "androidx.camera:camera-camera2:$camerax_version"
implementation "androidx.camera:camera-lifecycle:$camerax_version"
implementation "androidx.camera:camera-view:1.0.0-alpha20"
SOLUTION:
// CameraX
def camerax_version = '1.0.0-rc01'
implementation "androidx.camera:camera-camera2:$camerax_version"
implementation "androidx.camera:camera-lifecycle:$camerax_version"
implementation "androidx.camera:camera-view:1.0.0-alpha20"
