CameraX crashing randomly with IllegalStateException

Question

I'm using CameraX API in my app. I have bound a Preview UseCase and an ImageAnalysis UseCase to an Activity lifecycle like

preview.previewSurfaceProvider = frontFacingCameraPreviewSurface.previewSurfaceProvider
imageAnalysis.setAnalyzer(mainExecutor, myAnalyzer)
cameraProvider.bindToLifecycle(this as LifecycleOwner, cameraSelector, preview, imageAnalysis)

The app works most of the time but randomly crashes with following logs

The exception occurs mostly during launching the activity or closing the activity. Any idea why it occurs?

Possible error at this piece of code on your snippet "this as LifecycleOwner". — Gurupriyan, Jan 17 '20 at 09:03
Are you use some dependencies to CameraX? If no, try this: https://stackoverflow.com/questions/56227684/java-lang-illegalstateexception-camerax-not-initialized-yet — Max Shwed, Jan 17 '20 at 12:25

i have somehow fix my issue by using updated version of camerax library and preview:

    def camerax_version = "1.0.0-beta03"
    implementation "androidx.camera:camera-camera2:${camerax_version}"
    // If you want to use the CameraX View class
    implementation "androidx.camera:camera-view:1.0.0-alpha10"
    // If you want to use the CameraX Extensions library
    implementation "androidx.camera:camera-extensions:1.0.0-alpha10"
    // If you want to use the CameraX Lifecycle library
    implementation "androidx.camera:camera-lifecycle:${camerax_version}"
