Hello @nacho007,

thanks for your report, I'm working on a fix and keep you updated.

[SenNeonoveNoci]

@nacho007 I have identified the issue, I will prepare a build with a fix for you. It will be out tomorrow.

[SenNeonoveNoci]

@nacho007 I'm so sorry for the delay, but here is a fixed build for you:

implementation 'com.smartlook.recording:app:1.8.10-native-internal-log'

Hi there, now we are having a crash when the app is signed in release mode and this function is called: private fun scrollDown() { val executor: ScheduledExecutorService = Executors.newSingleThreadScheduledExecutor() executor.schedule( { binding.svMainContent.fullScroll(View.FOCUS_DOWN) }, 500L, TimeUnit.MILLISECONDS ) }

This function is for scrolling automatically some content when an edit text gains focus. Data: Model:Pixel 4a (5G), Version:Android 12, Orientation: Portrait.

Crash:

@nacho007 Let me look into this and fix it.

[SenNeonoveNoci]

@nacho007 Can you please try this build:

implementation 'com.smartlook.recording:app:1.8.10-native-focus-null

It should fix your issue. Also all the fixes I have posted here would be included in an official release of the SDK next Monday/Tuesday.
