Fatal, uncaught InterruptedException: No surface became available

[jpribble]

I just upgraded to v2.0.0 and found this fatal exception when first starting the camera. It only occurred once and I was unable to reproduce it (tried about 30 times).

How did you initialize FA?

Fotoapparat
        .with(this)
        .into(cameraView!!)
        .previewScaleType(ScaleType.CenterCrop)
        .photoResolution([custom_selector])
        .previewResolution([custom_selector])
        .lensPosition(single(LensPosition.Back))
        .focusMode(firstAvailable(
            continuousFocusPicture(),
            autoFocus(),
            fixed()))
        .flash(off())
        .frameProcessor {
          processFrame(it)
        }
        .previewFpsRange(highestFps())
        .cameraErrorCallback { e ->
          [error_handling_code]
        }
        .logger(logcat())
        .build()

What was the result you received?

Fotoapparat crashed with a fatal exception when trying to start the camera.

What did you expect?

Expected for the camera to start successfully and not crash. If there is an exception while starting, pass the error to the cameraErrorCallback listener.

Context:

• FA version: 2.0.0
• Devices affected: Samsung Galaxy S8 running Android 7.0

Let's do that. Should be happening only if the CameraView#onDetachedFromWindow got called quicker than the preview surface became available. UnavailableSurfaceException will be returned in cameraErrorCallback for transparency but can be normally get ignored.
